Abstract
A biocompatible meniscal repair device is disclosed. The tissue repair device includes a scaffold adapted to be placed in contact with a defect in a meniscus, the scaffold comprising a high-density, dry laid nonwoven polymeric material and a biocompatible foam. The scaffold provides increased suture pull-out strength.
Claims26
A biocompatible meniscal repair device, comprising;
- a biocompatible tissue repair scaffold adapted to be placed in contact with a defect in a meniscus, wherein the scaffold comprises a dry laid nonwoven polymeric material, the dry laid nonwoven polymeric material consists of a density in the range of about 120 mg/cc to 360 mg/cc, and wherein the scaffold has an initial modulus of elasticity greater than 1.5 MPa or about 1.5 MPa and an initial suture pull-out strength greater than 6 N or about 6 N, and wherein viable tissue is disposed on the tissue repair scaffold, the viable tissue having viable cells capable of integrating with native tissue adjacent to the tissue repair scaffold.
A biocompatible meniscal repair device, comprising
- a biocompatible tissue repair scaffold adapted to be placed in contact with a defect in a meniscus, the scaffold including:
