An interactive restraint system for securing catheters in position following installation in a human or animal patient and preventing movement or unplanned removal thereof in response to the application of significant forces in any direction thereto, be they longitudinal, torsional/rotational or bending. The system includes a retention collar which can be secured to any catheter and releasably interacts with a securing device attached to a patient to ensure proper positioning of the catheter. The restraint system includes a unique universal, after-market applied retention collar readily adapted for use in hospital and field emergency situations to engage any catheter and facilitate ease of application and positioning under all conditions.

A holding mechanism assembly 1 includes: a tubular inserting member 2; a fixing device 3 having a fixing portion 31 and a communicating portion 32; and a holding structure 4 to hold the inserting member 2 to the fixing device 3 in a liquid tight manner. The communicating portion 32 has a first opening 321 opened toward the outside of the living body; a second opening 322 opened toward the inside of the living body; and a communication path 323 formed between the first opening 321 and the second opening 322. An outer surface 2a of the inserting member 2 has a covered region A1 covered with fiber that can guide cells and a non-covered region A2 not covered with fiber, and the non-covered region A2 extends between the holding structure 4 and the second opening 322.

The present disclosure concerns a vascular access device (1) comprising a vascular access tube (2), such as a cannula, having a distal end region (3) terminating in a tip (4) for insertion into a blood vessel (V) of a patient and at least one lumen (5) for infusing a medicament and/or for introducing one or more catheters there-through into the blood vessel (V). The device (1) further comprises a fixation mechanism (10) that is operable to secure or fix the distal end region (3) of the vascular access tube (2) with respect to the patient to inhibit or prevent withdrawal of the tip (4) from the blood vessel (V) and/or to inhibit or prevent overinsertion of the tip (4) into the blood vessel (V). The tip (4) of the vascular access tube (2) has an opening (6) for communication between the at least one lumen (5) of the access tube (2) and the blood vessel (V) of the patient into which the tip (4) is inserted, and the fixation mechanism (10) is desirably configured to position and fix the opening (6) of the tip (4) at or adjacent a wall (W) of the blood vessel (V) at a point of insertion of the tip (4). The fixation mechanism (10) is preferably configured to secure or fix the vascular access tube such that the access tube extends longitudinally at a predetermined angle (#) with respect to the blood vessel (V) at a point of insertion of the tip (4). The predetermined angle (#) may be within the range of about 20 degrees to about 90 degrees. The disclosure provides a corresponding method of implanting the vascular access device (1) in a patient.

A system for attachment of a device to a bone is provided. The system includes an internal axial rod with a proximal and distal end that is configured to be inserted and secured into a bone cavity's distal end. The system can also include an internal-external transfer rod with a proximal and distal end mounted into the distal end of the axial rod and a central channel extending through the transfer rod from the proximal end to the distal end and a plurality of attachment rings for attaching at least one tissue or muscle group to the transfer rod. The system also includes a bio-compatible and bio-occlusive artificial membranes (BIOCAMS) lamina, wherein the lamina includes either a polyetheretherketone (PEEK) mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissue, allogenic tissue, a collagen/hyaluronic acid-based tissue, or connective tissue biosynthetic substrate material suitable as webbing.

A drug delivery system including an implantable reservoir containing drug microspheres, with an innocuous fluid flushed through the implantable microsphere reservoir to form a drug containing solution for delivery within a body of a patient.

The present disclosure relates generally to the field of medical devices and drug delivery. In particular, the present disclosure relates to implantable medical devices, systems and methods for controlled and consistent drug release through a porous body into a patient.

A vascular access system can include a port configured to be implanted outside of a target body lumen, at least one conduit fluidly connected to the port, and at least one one-way valve proximate the distal end of the conduit and within the fluid pathway of the sidewall of the conduit. The system can also include a gateway element comprising a through lumen operably connected to an outer diameter of the conduit, the gateway element comprising a first radially compressed configuration in which the gateway element causes occlusion within the through lumen, and a second radially expanded configuration in which the gateway element permits passage of fluids within the through lumen.

A medical anchor device (1) for securing a medical article to a subject comprising an upper medical article attachment portion (2) and a lower insertion portion (3) for securing the medical anchor device (1) to the subject wherein the insertion portion (3) comprises a spiral anchor (5) so that the medical anchor device (1) is securable to and detachable from the subject by rotating the medical anchor device (1) in a clockwise or an anti-clockwise manner as required by the direction of the spiral anchor (5).

A catheter system includes abase plate having a bottom surface, an outer circumferential wall, a circular flange extending inwardly from the outer circumferential wall, and an inner ring that is spaced apart from the outer circumferential wall, extends upwardly from the bottom surface, and defines a central opening in the base plate. A catheter is placed within the central opening of the base plate. A cover is placed over and secured to the base plate. The cover has a closed upper portion defining an internal chamber of the cover and a lower portion defining an opening in the cover. The lower portion includes a skirt with a flange extending outwardly around a periphery of the skirt to engage the circular flange of the base plate and form a closed reservoir. Methods of accessing cerebrospinal fluid using the catheter systems are also provided.

An assembly for attachment to a gastrostomy feeding tube is provided. The assembly comprises a valve connector and an anchor. The valve connector comprises a housing, a conduit traversing the housing from an inlet to an outlet; and a retaining element extending outwardly from the housing. The anchor comprises an anchor housing configured to receive a portion of the valve connector. The anchor housing has a gastrostomy feeding tube attachment feature for attaching the anchor to the feeding tube, and a valve connector retaining feature that defines a retaining space, wherein the retaining space receives the retaining element of the valve connector and is sized to enable rotation of the retaining element and the valve connector relative to the anchor such that the conduit of the valve connector maintains fluid connection with the gastrostomy feeding tube during rotation. Additional assemblies and systems are also provided for other medical devices.
