摘要:
A method of making a bioprosthetic device comprises treating a surface of a synthetic layer to increase the hydrophilicity of the surface, and securing the surface of the synthetic layer to a layer of naturally occurring extracellular matrix material. The synthetic material is a bioabsorbable fibrous material, selected from the group consisting of PLA, PGA, PCL, PDO, TMC, PVA, copolymers thereof, and blends thereof.
摘要:
An implant device (50) for cartilage regeneration in loading-bearing regions is formed of resorbable polymeric materials. The implant (50) is designed such that load is transmitted from the articulating surface of the bone platform (40) through the implant (50) to the entire area of subchondral bone (45) of the bone platform (40). Application of load in this manner results in reduced subchondral bone resorption, leading to joint stabilization and maintenance of normal joint biomechanics. The implant (50) allows for the incorporation therein of a resorbable scaffold or matrix material.

摘要:
A method of making a bioprosthetic device, the method comprises coating a synthetic layer with a comminuted naturally occurring extracellular matrix material, positioning the coated synthetic layer between a first layer of naturally occurring extracellular matrix material and a second layer of naturally occurring extracellular matrix material to make an assembly, and applying positive pressure to the assembly. The synthetic material is a bioabsorbable fibrous material, selected from the group consisting of PLA, PGA, PCL, PDO, TMC, PVA, copolymers thereof, and blends thereof.
