Summary for Patent: 6,656,488

Title:	Bioabsorbable bag containing bioabsorbable materials of different bioabsorption rates for tissue engineering
Abstract:	A device for tissue engineering is formed of a porous bioabsorbable bag containing at least two bioabsorbable materials having different rates of bioabsorption such as beads of different degrading rates and a bioabsorbable binding gel such as fibrin that binds the bioabsorbable materials in relation to each other. Slow degrading beads and the bag may be made of a copolymer of poly(L-lactide) and poly(glycolide), and fast degrading beads may be made of gelatin. The bag may contain cells and/or wound healing stimulants such as growth factors. Hydrolyzing enzymes may be used to enhance biodegradation of polymers. The device can be used to promote in-growth of host tissue into a void by inserting the bag with its contents into the void and conforming the bag to a desired shape. The binding gel may be injected into the bag after being placed in the void .
