Lyophilized Foams of End Block Containing Absorbable Polymers

摘要

Novel absorbable foams, lyophilizing solutions, and lyophilizing and annealing processes are disclosed. The foams are made from copolymers of glycolide and epsilon-caprolactone. The foams are useful in or as implantable medical devices.

主权项

1. An absorbable polymer foam, comprising:
a semicrystalline absorbable segmented copolymer having a random segment of repeating units of polymerized glycolide and polymerized epsilon-caprolactone and at least one segment that comprises predominantly polymerized glycolide, wherein the mole ratio of polymerized glycolide to polymerized epsilon-caprolactone of the entire segmented copolymer is between about 55:45 to about 65:35, and having a mole ratio of polymerized glycolide to polymerized epsilon-caprolactone in the random segment between about 45:55 to about 60:40.
