The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

A method of manufacturing an implant, including mixing a first quantity of biocompatible polymer particles, a second quantity of bioactive ceramic particles, and a third quantity of fugitive material particles to define an admixture, forming the admixture to define a composite body having an inferior portion, a superior portion and a central portion disposed between the inferior and superior portions, heating the admixture to fuse the first quantity of bioactive polymer particles to define a composite implant body, and infiltrating the composite implant body with a solvent to remove fugitive material particles to yield a network of interconnected pores and to define a porous implant body. The fugitive material particles are hollow spheres partially filled with a material selected from the group comprising air, bioactive agents, biological growth enhancers, drugs, and biocompatible polymer material, combinations thereof.

A spacer for a knee replacement prosthesis may be provided. The spacer may include a lower surface, the lower surface having a locking component adapted to interlock with a tibial tray; an upper surface, the upper surface having an optional central femoral guide and a pair of condyle support platforms, each of the condyle support platforms being disposed on an opposite side of the central femoral guide, each of the condyle support platforms being smooth, the surface of each of the condyle support platforms further having a shallow concavity; and a body incorporating the upper and lower surfaces, the body having a hollow outer portion surrounding an internal reservoir, the body being impermeable to fluid; the body further having one or more ports, each with a channel, each channel extending through the hollow outer portion of the body directing the flow of fluid in and out of the port(s).

Techniques and devices for improved breast surgeries are provided. The devices can include tissue matrix and synthetic meshes for surrounding breast implants or tissue expanders to provide improved implant outcomes for pre-pectoral implantation or other implantation techniques.

A surgical implant and a surgical kit. The surgical implant having a body for contacting and supporting adjacent vertebrae. The body has a) opposing superior and inferior surfaces with or without corrugations, b) recesses formed in the opposing superior and inferior surfaces within a peripheral boundary of the body, and a recess-fill material (which preferably promotes osseointegration) disposed in the recesses.

The present invention provides a valved vascular prosthesis and a manufacturing method thereof. The valved vascular prosthesis, comprising an artificial blood vessel and a valve disposed inside for obstruction; the valve is in a skirt state extending toward the centerline of the artificial blood vessel; the valve is made by sewing a tubular vascular material on the artificial blood vessel; one end of the vascular material is connected to the artificial blood vessel along its radial direction, and the other end is a free end; the entire tubular body of the vascular material is sewed on the artificial blood vessel by a plurality of sutures; the sutures are radially parallel to the tubular body of the vascular material, and are arranged at intervals along the circumference of the tubular body of the vascular material. The valved vascular prosthesis of the present invention adopts suture of a polymer material and an artificial blood vessel. When the valved vascular prosthesis is implanted into human body, the valved part is implanted together. The process is simple, easy to mold and has good biocompatibility.

An annuloplasty repair segment for heart valve annulus repair and a method for forming. A multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves which allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. The particular shape of the annuloplasty ring is fixed using a heat setting process including heating the flexible core member to a temperature higher than 500° C. and holding it in a desired heat-set saddle shape for a period of time. The core is then rapidly cooled to impart physical properties such that the flexible core member can be straightened, during implantation, to fit through a tubular access device and regain the heat-set saddle shape after exiting the access device and, when attached to the native heart valve, the flexible core member is strong enough to remodel the native heart valve.

A total knee implant prosthesis is disclosed. The total knee implant prosthesis includes a tibial component including a pair of bearing surfaces and a post positioned between the bearing surfaces, and a femoral component configured to rotate relative to the tibial component. The femoral component includes a pair of condyles sized and shaped to articulate on the bearing surfaces and a cam positioned between the pair of condyles. The cam engages the post at a first contact point when the femoral component is at 0 degrees of flexion and engages the post at a second contact point located lateral of the first contact point when the femoral component is at a first degree of flexion greater than 0 degrees. The cam is disengaged from the post when the femoral component is at a second degree of flexion greater than the first degree of flexion.
