DETAILED DESCRIPTION

[0058] Turning to FIG. 1, a view of an embodiment of the present invention is shown with the following general components and interfaces: distal end amputation 1, long-bone prosthetic rod-implant 13 (also shown in FIG. 2) inserted into the long bone medullary cavity 1a, first muscle group 2, second muscle group 3, nerve attachment clips 4, BIOCL muscular attachment-ring 5, BIOCAM fascia attachment-ring 6, BIOCAM dermal/epidermal attachment-ring 7, nerve and biometric signal processor attachment connector 8, infusion-suction port(s) 9-xa, infusion-suction channels 9-xb, prosthetic implant-rod attachment ratchet (male) 10, prosthetic device attachment socket (female) 11, and a prosthetic attachment retention clip 12. Part 80 represents any compatible prosthetic attachment. As shown in FIG. 1, the infusion-suction ports 9-xa can be positioned on a lower portion of the axial implant-rod 13. The infusion-suction ports 9-xa allow both removal of puss and other fluids via the implant from within the contiguous body spaces and allow infusion of saline, antibiotics, and/or other medications via the implant into the contiguous body spaces. Further, the infusion-suction channels 9-xb connect to the infusion-suction ports 9-xa and allow flow into and out of the long bone medullary cavity 1a.

[0059] Turning to FIG. 2, 4, 5, most of the attachment to the axial skeleton long bone 1, is by the solely-internal (SI) long bone axial implant-rod 13 or the single internal-external (SIE) long bone axial implant-rods 22a, 22b composed of nickel-titanium or equivalent bio-acceptable material. The solely internal (SI) long bone axial implant-rod 13 or the single internal-external (SIE) long bone axial transfer implant-rods 22a, 22b insert into the long bone medullary cavity 1a. Additionally, an optionally included porous nature of the surface of the SI long bone axial implant rod 13 and the SIE long bone axial transfer implant-rods 22a, 22b allows the bone matrix to grow into conformity and mechanically provide for a union with the long bone axial implant-rod.

[0060] In an embodiment as shown, the SI long bone axial implant-rod 13 can be hollow for accepting the IE transfer implant-rod 19. The SIE long bone axial implant-rods 22a, 22b provide the combined mechanical interface of the SI long bone axial implant-rod 13 and the IE transfer implant-rod 19 in one element. FIG. 2 illustrates an exploded view of an embodiment of the present invention wherein an internal-external (IE) transfer implant-rod 19 with matching screw interfaces 21a on an upper portion of the exterior of the IE transfer implant-rod 19 mates with matching screw interfaces 21b on an internal portion of the SI long bone axial implant-rod 13. Further, infusion-suction channels 9-2b within the IE transfer implant-rod 19 align with infusion-suction channels 9-2d of the SI long bone axial implant-rod 13. As best seen in FIG. 2, the channels 9-2b have an outlet 9-2c on a tip of the IE transfer implant-rod 19 which aligns with the channels 9-2d on the SI long bone axial implant-rod 13 and allows for fluid to flow into and out of the medullary cavity 1a with an outlet 9-2e on a tip of the SI long bone axial implant-rod 13. Further, infusion-suction channels 9-3a, 9-4a within the SIE long bone axial implant rod 22a,22b are continuous with the infusion-suction channels 9-3b, 9-4b and have their outlet at the tip of the SIE long bone axial implant rod 22a, 22b at the rod's tip 9-3b, 9-3b.

[0061] Embodiments of the SI long bone axial implant-rod 13 and the SIE long bone axial transfer implant-rods 22a, 22b may have screw-like proximal segments 14. The screw-like section transfers weight bearing forces from the long bone axial implant to the long bone 1, or from the long bone 1 to the either the SI long bone axial transfer implant-rod 13 or the SIE long bone axial implant-rods 22a, 22b and thereby to the entire implanted transcutaneous system 100. The entire implanted transcutaneous system 100, can have clamps 17, which clamp to the external surface—periosteum—cortical surface of the long bone by appropriately shaped clamps 17 with pointed/ridge-like peaks 17a that grasp the long bone mechanically.

[0062] These clamps can mount to the long bone axial implant-rod by fixation screw 16 through the clamps and through the distal end of the long bone axial implant-rod 13, 22a, 22b via screw bores 15. This arrangement transfers external rotational forces from the prosthetic 80 to the entire implanted system 100 and subsequently to the long bone. Possible extrinsic forces that could pull at the implant would include turning a knob or a screwdriver or the kickback torsion from a power drill. Additionally, this segment of the long bone axial implant-rods 13, 22a, 22b with the bore holes 15 may have a square, or hexagonal segment 18 which allows for mechanically turning the long bone axial implant-rods during implantation.

[0063] Additionally, the long-bone axial implant-rod fixation screws 16 extend through the long bone bores holes 15 and into the medullary shaft of the long bone providing additional mounting stability against forces transmitting from the external environment to long bone of the body. The hexagonal segment 18 can include multiple bore holes 15 and fixation screws 16, and in embodiments not shown may include one and/or a plurality of bore holes 15 and fixation screws 16.

[0064] The fixation clamps 17 can have several rows of ridged peak mounting teeth 17a that grip into the external cortical bone-periosteum as a mechanical-structural-force interface. The fixation screws 16 can also penetrate through the periosteum and into the endosteum for additional mechanical fixation. The solely internal (SI) long bone axial implant-rod 13 may be hollow and can accept an inserted internal-to-external (IE) transfer implant-rod 19. The IE transfer implant-rod 19 (as shown in FIGS. 2 and 3) can provide for the physical connection between the entire implanted system 100 and the soft tissues of the limb and the external environment.

[0065] For the SIE long bone axial transfer implant-rods 22a, 22b, (as shown in FIGS. 4 and 5) the proximal end provides the physical connection between the long bone 1 and the distal end and connects to the external environment. The IE transfer implant-rod 19 inserts into the long bone axial implant-rod 13 and screws into place with matching screw interfaces 21a, 21b, to mount it within the long bone axial implant-rod 13 and provide for substantive force and weight bearing transmission from the long bone 1 to the long bone axial implant-rod 13 and to the IE transfer implant-rod 19. The IE transfer implant-rod 19 and the SIE long bone axial implant rod 22a, 22b interface to the soft tissues of the limb by various BIOCAM lamina-rings 31 and BIOCL 32. It connects to external prosthetics via a matched mechanical junction system for substantive force and weight bearing and transmission to a male/female dual ratchet-socket mechanism, 10 and 11 respectively.

[0066] The SI long bone axial implant-rod 13 and the SIE long bone axial implant rod 22a, 22b have bore holes 15 through which fixation screws 16 attach fixation clamps 17 and into the long bone itself. Additionally, the segment of the SI long bone axial implant-rod 13 and the SIE long bone axial implant-rod 22a, 22b with the bore holes 15 may have a square, or hexagonal segment 18 which allows for mechanically turning the long bone axial implant-rod 13, 22a, 22b into the long bone 1 during implantation. The IE transfer implant-rod 19 is inserted and screwed into the SI long bone axial implant-rod 13 by matching screw interfaces 21a and 21b. The IE transfer implant-rod 19 has an exterior screw segment 21a which mates with the SI long bone axial implant-rod's 13 interface interior bore screw segment 21b.

[0067] The IE transfer implant-rod 19 is affixed to the distal end of the long-bone axial implant-rod 13 by screw bores 15 and fixation screws 16. Additionally, the IE transfer implant-rod 19 fixation screws 16 and SIE long bone axial implant-rod 22a, 22b fixation screws 16 extend through the long bone bores holes 15 and into the medullary cavity 1a of the long bone 1 providing additional mounting stability against forces transmitting from the external environment to long bone 1 of the body. The diagram shows multiple bore holes 15 and screws 16, but not all may be necessary to be utilized at the time of implantation.

[0068] The fixation screws 16 also mechanically attach the axial implant-rod to the long bone by clamps 17 with pointed-ridged peaks 17a gripping the external surface—periosteum—cortical surface of the long bone 1. The fixation screws 16 also penetrate through the periosteum and into the endosteum for additional mechanical fixation.

[0069] Turning to FIGS. 3-9, “PEEK” stands for polyetheretherketone, which is a semi-crystalline, high temperature plastic. It is chosen to represent any selection of a large family of bio-neutral polymers available for surgical implantation purposes. The BIOCAM lamina can be constructed either from a PEEK mesh, a biocompatible metallic mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissues, allogeneic tissue, collagen/hyaluronic acid based tissue, and/or any other equivalent connective tissue biosynthetic substrate material suitable as webbing for surgical implantation into the body.

[0070] The BIOCAM lamina can further include any formation of transitional webbed areas interlaced across a biocompatible material scaffolding and may allow for a range of degrees of bio-integration or bio-dissolution. The webbed area can include a generally central area that is more densely woven and has a decreasing density of webbing as it approaches the outer edge of the lamina. The host body's tissue layers can be sutured or glued onto and into the webbed areas of the lamina. The lamina materials may further include surface coated molecules of epithelial growth factors or other growth factors. Biocompatible linkages (BIOCLs) for attachment to tendon & muscle groups are generally made of similar materials as BIOCAMs. BIOCAMs and BIOCLs allow for “cytointegration” and “organointegration” of the BIOCAMs and BIOCLs with bodily tissues.

[0071] In FIGS. 1, 3, 4 the IE transfer implant rod 19 and the SIE long bone axial implant-rod 22a may have an included channel 20 which may be a groove along the rod's edge, or a channel within the IE transfer implant-rod 19 or the SIE long bone axial implant rod 22a through which a sealed micro-wire cable 23 which is insulated with PEEK, a carbon fiber or other bio-acceptable dielectric material, attaches to a modified Utah Array 46, in FIG. 10, which itself interfaces to a nerve/nerve bundle 46, 47. Additionally, optionally included biometric sensors can attach to the same transmission bundle.

[0072] The micro wire 23 runs from inside the limb or body region from the nerve attachment sites and biometric sensor sites, then passes down the IE transfer implant-rod 19 or the SIE long bone axial transfer implant-rod 22a at the channel 20 and exits those implant-rod channels to the exterior of the body, where it can attach by an appropriate connector to an external processor connection 26. The biocompatible signal conduit may have an optionally included additional sheathing or sub-conduit which may be fenestrated 23s along portions to allow infusion of fluids such as antibiotics along its length via an external port.

[0073] The micro-wire cables 24 can come in bundles 27, and attach to micro connectors 28 that clamp directly onto an associated nerve or nerve bundle (see FIG. 10). The IE transfer implant-rod 19 and SIE long bone axial transfer implant-rods 22a, 22b have a Tissue Attachment BIOCAM lamina-Ring and BIOCL Region (TARR) 30 comprised of gear-like pitches-teeth-ridges shown in cross-section 29a to which mating slotted ring hubs 30a of the BIOCAM/BIOCL tissue rings shown in cross section 30a allow mechanical attachment, force translation, environmental barriers and various connective purposes at various tissue layers.

[0074] Referring to FIGS. 3, 4, 5, 6A-6C, and 7A-7E, in general, there is an attachment-ring for any BIOCAM lamina-ring 31 and BIOCL 32 for limb tissue attachments. BIOCL-muscle attachment-rings may be for one, two, three, four or more associated muscle groups 31. There are BIOCAM lamina-rings 31 attachments for tissue closure at the fascia and dermal layers.

[0075] Each BIOCAM lamina-ring will attach by sliding its hub 30a into position along the TARR 30 (tissue attachment-ring region). BIOCAM lamina-rings 31 and BIOCL rings 32 are fastened together by longitudinal bore holes 34 and screws 35 mounted. The most distal ring 30-1, which may be a mounting ring not otherwise used for tissue connection, is mounted via a transverse bore hole 36a mounted screw 36. Optionally, each attachment-ring may be each mounted via a similar bore and screw method.

[0076] At the end of the I E transfer implant-rod 19, or SIE long bone axial transfer implant-rods 22a, 22b and external to the limb or other bodily attachment point, is a dual ratchet type connector 10 sized for appropriate load bearing.

[0077] There is a simple ratchet retention spring-ball system 39 for initial connection. Between the two ratchet areas is a central rod area for a retention clip 12 to maintain definitive attachment of external prosthetic devices. Optionally included is any form of appropriate attachment hardware design configuration. In embodiments not shown, the system can include attachment devices between the implant 100 and the prosthetic 80 such as, but not limited to, magnetic coupling devices, electro-mechanical locking devices, rigidly fixed connectors, quick connect and disconnect connectors, snap-on/snap-off devices, and twist and click attachment connectors.

[0078] The BIOCAM lamina-rings 31 and BIOCLs 32 attach to the IE transfer implant-rod 19 or the SIE long bone axial transfer implant-rod 22a, 22b at the TARR—tissue attachment-ring region 29 of the implant-rods at the tissue ring central hubs 30a via matting gear-like pitches-teeth-ridges shown in FIGS. 3-7. The BIOCL rings that attach to muscle groups include from one to four or more attachment flanges 37 in FIGS. 6B, 6C, designed as levers connecting between muscle/tendons and the IE transfer implant rod 19 or the SIE long bone axial transfer implant-rods 22a, 22b.

[0079] Additionally, the adjacent, minimally weight bearing long bone, such as the radius-ulna or tibula-fibula which is not joined to the IE transfer implant-rod or the SIE long bone axial transfer implant-rod TARR, can be attached to a muscle flange via screw bore holes 38 and screws 38a for concurrent fixation. Muscle fibers 5 or tendons are surgically attached to the flanges 37 via suturing, stapling, gluing or similar means to a mesh network 40, 41 to provide intra-limb force transfer from the host body to the rod assemblies.

[0080] The BIOCAM lamina-rings 31, and BIOCLs 32 may have a metal, including nickel-titanium, mounting scaffold 40 as a skeletal framework, with a biocompatible webbing-mesh 41—described in section 0045—for sutures, staples, glue, or similar means for cyto-cellular attachment. The BIOCAM lamina-rings for fascia and dermal attachment may have a transitional web/mesh 42 with the central area being a solid biocompatible material attached and may be based upon a nickel-titanium scaffold.

[0081] This transitions to a progressively “looser” web zone of the specific biocompatible material-lamina and ends at the outer ring of metal scaffold. The mesh and sub-mesh may be composed of a PEEK mesh, a biocompatible metallic mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissues, allogeneic tissue, collagen/hyaluronic acid based tissue, any other equivalent connective tissue biosynthetic substrate material suitable as webbing for surgical implantation into the body.

[0082] It is into this biocompatible webbing 41 which the fascia 6 or dermal 7 layers are sutured, stapled, glued or similarly joined, and into which the fascia and dermal will grow and interweave with for exclusion of any external environment when fully healed. Such interfaced healing may be augmented by the use of epidermal growth factors or vascular endothelial growth factors, or similar endovascular growth promoting molecules.

[0083] Referring to FIGS. 1, 3, 4 and 11A-11B, the micro-wire cables 23 attached to typically to appropriately sized sensor/stimulator Utah Array matrix 44 arising from a semiconductor substrate 45 and mounted within nerve/bundle clips 43. The Utah Array penetrate through each associated nerve sphingomyelin nerve sheath 46a into the nerve cytoplasm 46b itself and clamps 43 onto the nerve(s) 46. The nerve(s) 46 are penetrated by appropriately sized modified Utah Array, potentially of carbon fiber spindles or similar bio-neutral conductor, which are integrated onto silicon on insulator (SOI) or similar semiconductor substrate, typically with an integrated digital signal processor (DSP) which uses analog to digital conversion, signal compression, time division multiplexing or similar asynchronous to synchronous multiplexing of data into a single or few digital streams for transmission through the micro-wire cable to external processing.

[0084] External feedback to the nervous system is via the essentially reverse process. Other biometric data can also be integrated into the same data flow. FIGS. 11A and 11B show the orientation of the Utah array 44 longitudinally so spindles either increase or decrease in height and depth of nerve penetration along the length of the nerve, while other optional orientations can also occur.

[0085] The SOI-semiconductor substrate long dimension potentially ranges from about 0.5 mm to about 5 mm, according to the size of the target nerve/bundle. The Utah Array 44 is potentially composed of carbon fibers or other semiconductor spindles measuring about 1-100 um diameter spaced about 1 um-1 mm apart, and are about 0.5 mm to about 5 mm high, and are optionally partially coated with sphingosine, or another nerve sheath cell related molecule. The spindle coating allows for a more integrated transmembrane entry through the nerve sheath cell membrane and into the cellular cytoplasm.

[0086] Human nerves typically are 0.1-5 micrometers in diameter. Current generation integrated circuit transistor gate size is about 3-5 nm. The DSP is configurable after implantation to group sets of the UA spindles into functional groups and sensory or excitatory pathways.

[0087] The DSP detects the changes in the nerve cells' ion fluxes, surface potentials and internal voltages. It digitizes that information (at potentially 8-24 bit resolution) and serializes the information to allow connection 8 to exterior processing elements for transmission of the nerve signal data to the external environment. The nervous system connection and processing system also allows feedback signals to be returned to the nerve bundle by digital to analog processing via the same UA/DSP and potentials gated out to the UA array/nerve interface. Biometric sensors can transmit data along the same digital path.

[0088] Referring to FIGS. 8A, 8B, 8C, 9A, and 9B, an additional type of transverse prosthetic attachment 48 is shown mounted in transverse-perpendicular direction to a particular bone, such as the radius-ulna (forearm) 49a or ileum (lateral pelvis) 49b. These implants are meant for load bearing, load stabilization and external accessory attachment but not for high impact or high torsion connections.

[0089] The transverse bone implant 48 has a central-anchor 52 which is a metal, such as nickel-titanium, or carbon fiber or other appropriate highly tensile bio-neutral material. The implant 48 has BIOCAM lamina-ring zones 50 for attachment to fascia and dermis, similar to areas 32, 40, 41 and 42 in FIGS. 6A and 6B. The central-anchor has a screw-like region 52a which provides durable mechanical interface to cortical and/or medullary bone. Additionally, there is an engagement-region 53 comprised of gear-like pitches-teeth-ridges, which provides rotational stability to the implant. Additionally, an optionally included porous nature of the engagement-region 53 and the central-anchor screw-like region 52a allows the bone matrix to grow into conformity and mechanical union with the central-anchor.

[0090] Additionally, an optionally included long mounting screw 55 transverses through the bore 55a in the anchor's rim 51 and anchors through the periosteum into the endosteum to provide supplemental resistance to torsion and longitudinal forces that could dislodge the anchor. The central-anchor itself has a central channel 56 that is visible at the skin surface. A pronged-stud connector 57 fits into the central channel 56 and provides mechanical connection to any appropriate mount via at least one pronged-studs 57a that inserts into locking channels 58 and the pronged-stud 57a turns into a locked position and is spring 59 pressure loaded into a held-retained position. Other mechanical junction methods are optional between the central-anchor and an exterior attachment.

[0091] Any attachment of appropriate size and purpose could mount to the accessory pronged-studs, such as a load bearing backpack, additional attachments to a large manually operated tool, and so on.

[0092] A rubber or biocompatible plug 57-2 inserts into the empty stud's central channel to keep the connector clean between uses and would have texture and color similar to the host body.

[0093] It is an embodiment of the present invention to provide a new system and method for improving percutaneous, bio-compatible and bio-occlusive attachment of medical devices including a wide array of tubes and catheters. These percutaneous interfaces potentially include mechanical interface—including air and fluid interface, neuronal interface, and sensory/biometric interface. In an embodiment of the present invention is a system to provide placement of a percutaneous catheters or tubes which have (a) bio-compatible and bio-occlusive artificial membranes (BIOCAMs) tissue attachment lamina to allow for attachment to any epithelial, mesothelial or endothelial derived tissue layer such as dermal, fascial, endothelial, mucosal, and pleural tissue layers and/or potentially multi-flanged biocompatible linkages (BIOCLs) for attachment to tendon & muscle groups for prolonged or semi-permanent periods of placement, which we call cytointegration and organointegration.

[0094] The BIOCAM lamina may have portal head through the lamina itself, typically within the central region, for external connection to the internally based catheters or tubes. The portal head contains all the ports for that particular catheter or tube. FIGS. 10a, 10b, and 10C, show three types of BIOCAM based catheters. In FIGS. 10a, 10b, and 10c, 60a, 60-1a, 60-2a, 60-3a, 60-4a are the external access ports to the catheter. The catheters themselves 62 may have as many sub-ports and channels as is deemed needed and reasonable for manufacture and use. The BIOCAM catheter may have an optionally included additional sheathing or sub-conduit which may be fenestrated 60s along portions to allow infusion of fluids such as antibiotics along a portion of its length via an external port 9-6a. This catheter sheathing would typically sheath the portion of the catheter that transitions through other tissues as it extends towards its intended distal position, for example the subcutaneous tissue of the back and retroperiteum for a percutaneous nephrostomy tube. The external access ports will likely have multilayer connection port head 64. The portal head contains all the device's ports, negates leakage and allows controlled drainage, suction or infusion of fluids or air. The portal head likely has several mechanically joined layers that may include a lamina-integrated base layer with bidirectional valves, an ‘inner’ adaptor that screws or snaps into and rests upon the base layer and provides high pressure sealant connectivity and secondary flow valves and is a replaceable long-term device. A secondary adaptor screws or snaps into the ‘inner adaptor and rests upon the inner adaptor and further provides a secondary high pressure sealant layer and allows for selectable connectivity.

[0095] Finally, a cap optionally sits upon the secondary adaptor, and provides occlusive seal and skin tone and texture blending. The inner, secondary, and cap portal head adaptors are removable and allow replacement all but the base layer of the portal connection head for general replacement reasons, non-sterile cleaning, sterile cleaning, and updated connectivity. The internal ports themselves 60b, 60-1b, 60-2b, 60-3b are internal to the organ or bodily region and are continuous, for fluid and air flows, with the catheters' external ports of the same base number and letter pair (each 60a is continuous with 60b). The flows are regulated external the portal head by external devices, except for the flow valves within the portal head itself, which keeps any flow from occurring unless a port control cap is placed. The BIOCAM lamina 61a, 61b attach to appropriate tissue layers such as dermal and mucosal layers (i.e. bladder wall) to provide isolation of the exterior environment 61a and from leakage from the internal organ environment 61b into adjacent soft tissues.

[0096] The non-catheter-based catheter portal head infusion port 9-6a, 9-6b allows for infusion-suction of any antiseptic-antimicrobial fluids that are necessary to episodically and/or repeatedly, sterilize the local soft tissue environment of the catheter itself either directly at the internal portion of the portal head or into transitional tissues via a catheter sheath 60s. For these catheters, the BIOCAM lamina may be biocompatible and bioabsorbable, perhaps upon a carbon fiber or manufactured biologic tissue mesh, to allow integration of the catheter lamina into the surrounding tissue except for the portal head device itself. If extraction is necessary, the portal head device and catheter would be removed but the bodily integrated lamina would likely remain in-situ/in-place.
