Abstract
Textile vascular prostheses having a coating include an absorbable polymer in the form of a three-armed polyester having terminal hydroxyl groups from hydroxy acids polymerized onto a central trifunctional hydroxy compound, the three arms being tetrapolymers of lactide, ε-caprolactone, trimethylene carbonate and glycolide. The polymer is composed of about 30 to about 45 mol % of lactide, about 20 to about 40 mol % of ε-caprolactone, about 10 to about 28 mol % of trimethylene carbonate and about 10 to about 25 mol % of glycolide.
