FORMATION OF MONOLITHIC NANOSTRUCTURES ON PROSTHETIC DEVICES
A method for formation of monolithic nanostructures on an implantable device includes: a. depositing a metal film to a surface of the implantable device; b. heating the metal film for a period of time, such that the metal film transforms into multiple discrete nanoparticles, the multiple nanoparticles thereby forming an etch mask on the surface of the implantable device; c. etching the implantable device such that the surface of the implantable device is etched through the etch mask, thereby forming monolithic nanostructures in the surface of the implantable device; and d. (optionally) removing the etch mask, such as by immersion in an aqua regia solution.
Method of performing anterior cruciate ligament reconstruction using biodegradable interference screw
A method of replacing an ACL with a graft. The method provides for the drilling bone tunnels in a femur and a tibia. A replacement graft is provided having first and second ends. A biodegradable composite screw is provided. The screw is made from a biodegradable polymer and a bioceramic or a bioglass. At least one end of the graft is secured in a bone tunnel using the biodegradable composite screw.
Resorbable pouches for implantable medical devices
Biodegradable and resorbable polymer pouches are described for use with cardiac rhythm management devices (CRMs) and other implantable medical devices (IMDs), i.e., a pouch, covering, or other receptacle capable of encasing, surrounding and/or holding the CRM or other IMD for the purpose of securing it in position, inhibiting or reducing bacterial growth, providing pain relief and/or inhibiting scarring or fibrosis on or around the CRM or other IMD. Optionally, the biodegradable and resorbable pouches of the invention include one or more drugs in the polymer matrix to provide prophylactic effects and alleviate side effects or complications associated with the surgery or implantation of the CRM or other IMD.
Implants for inducing soft and hard tissue integration
The present invention provides a biocompatible implant comprising one or more metal(s), metal alloy(s), metal oxide(s) or a combination thereof, wherein an antioxidant compound selected from the group of flavonoids or methoxytryptophols, an ester thereof, a pharmaceutically acceptable salt thereof or a combination thereof, is/are coated to at least a part of a metal, metal alloy or metal oxide surface of said biocompatible implant. This implant is useful for replace bone tissue in vertebrate animals, and furthermore restore the normal function of said tissue, mainly due to its ability of induce osseointegration and soft tissue attachment.
Medical devices and implements with liquid-impregnated surfaces
Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.
Cell or tissue embedding device
A cell or tissue embedding device having an aqueous gel serving as an immunoisolation layer, the aqueous gel containing, as components thereof, a denatured polyvinyl alcohol resin having an activated carbonyl group and a crosslinking agent is highly capable of supplying a physiologically active substance.
METHOD FOR PRODUCING AN ATTACHMENT PIECE OF A COVER DEVICE FOR A BONE DEFECT SITE, AND DEVICE FOR COVERING AND/OR RECONSTRUCTING A BONE DEFECT SITE
A process for manufacturing a cap (4) which has at least one nominal breaking point (16) of a covering device for a bone defect site (2) and a device (1) for covering and/or reconstructing a bone defect site (2) are proposed, wherein through comparing a first data set which represents the affected bone defect site (2) in the actual condition with a second data set which represents the nominal condition of a regenerated bone at the bone defect site (2), wherein the second data set has been calculated or recorded at a time at which the bone at the site now to be regenerated was still a healthy bone (18) it is made possible that the regenerated bone produced through the regeneration of the bone defect point (2) has a shape which corresponds to the shape the bone had at the site to be regenerated when it was still healthy.
HYDROPHILIZATION AND ANTIFOULING OF ENHANCED METAL SURFACES
A coating for a roughened metal surface of an implantable medical device includes a poly(ethylene glycol) disposed on at least a portion of the roughened metal surface, wherein the poly(ethylene glycol) is covalently bonded directly to the roughened metal surface.
INFECTION RESISTANT SURFACES FOR DEVICES
This disclosure is directed to a medical device including a surface that has been roughened to provide a roughened surface that inhibits the adhesion of microorganisms on the roughened surface.
EXTRACELLULAR MATRIX SHEET STRUCTURES
An implantable medical product and method of use for substantially reducing or eliminating harsh biological responses associated with conventionally implanted medical devices, including inflammation, infection and thrombogenesis, when implanted in in a body of a warm blooded mammal. The bioremodelable pouch structure is configured and sized to receive, encase and retain an electrical medical device therein and to allow such device to be inserted into the internal region or cavity of the pouch structure; with the pouch structure formed from either: (a) first and second sheets, or (b) a single sheet having first and second sheet portions. After receiving the electrical device, the edges around the opening are closed by suturing or stapling. The medical device encased by the bioremodelable pouch structure effectively improves biological functions by promoting tissue regeneration, modulated healing of adjacent tissue or growth of new tissue when implanted in the body of the mammal.
