Patent ID: 8486143

Claim:
A device for replacement or regeneration of articular tissue comprising polymeric fibers degrading at between nine and twelve months following implantation, and polymeric fibers not degrading following implantation in less than one year, wherein the polymeric fibers are braided into a three-dimensional braided scaffold to form two end sections for attachment of the device at a site of implantation and at least one middle section between the end sections, wherein the polymeric braid of the middle section is more porous than the polymeric braid of the end sections and allows in-growth of connective tissue, and wherein the polymeric braids of the end sections are attachable to bone, have a porosity less than 50% and allow for ingrowth of bony tissue, wherein the device has a peak load strength range from 500 to 3200 N and provides articular tissue function at the site of implantation as tissue integrates into the device.
