Cartilage repair unit
First Claim
1. A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone, said system comprising a delivery unit and a porous insert;
- (A) said delivery unit being formed of bio-absorbable material and configured and dimensioned to be mounted in both an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone, said delivery unit having a central body and a plurality of radially extending, flexible support arms projecting outwardly from said central body and configured and dimensioned to support said insert; and
(B) said insert being formed of bio-absorbable material and establishing communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix.

Abstract
A bio-absorbable cartilage repair system is provided for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone. The system is an assembly of a delivery unit and a porous insert. The delivery unit is formed of bio-absorbable material and configured and dimensioned to be mounted in both an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone. The delivery unit has a central body and a plurality of radially extending, flexible support arms projecting outwardly from the central body and configured and dimensioned to support the insert at least partially thereover. The insert is supported by the delivery unit, formed of bio-absorbable material, and establishes communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix.

35. A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone, said system consisting essentially of two delivery units and a single flexible porous insert;
-
(A) each of said delivery units being formed of bio-absorbable material and configured and dimensioned to be mounted in both an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone, each said delivery unit having a central body and a plurality of radially extending, flexible support arms projecting outwardly from said central body and configured and dimensioned to support said insert; and
(B) said insert being formed of flexible bio-absorbable material and establishing communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix;
said delivery units being configured and dimensioned to enable them to be disposed facing each other and connected only by said insert for insertion into a patient and then unfolded to enable them to be separately mounted side-by-side. - View Dependent Claims (36)
