First Claim
Patent Images
1. A tendon or ligament repair implant, comprising:
- a biocompatible porous scaffold having an aspect ratio in the range of greater than 2 and less than 100; and
at least one minced tissue fragment derived from ligament tissue or tendon tissue, the at least one tissue fragment distributed on at least a portion of the scaffold at a concentration in the range of about 1 to about 100 mg/cm2, wherein the at least one tissue fragment has a particle size in the range of about 0.1 mm3 to less than 1 mm3;
wherein the scaffold is made from polymers or copolymers formed from monomers selected from the group consisting of lactide, glycolide, dioxanone, and caprolactone.

Abstract
A biocompatible ligament repair implant or scaffold device is provided for use in repairing a variety of ligament tissue injuries. The repair procedures may be conducted with ligament repair implants that contain a biological component that assists in healing or tissue repair. The biocompatible ligament repair implants include a biocompatible scaffold and particles of viable tissue derived from ligament tissue or tendon tissue, such that the tissue and the scaffold become associated. The particles of living tissue contain one or more viable cells that can migrate from the tissue and populate the scaffold.
