Patent ID: 8137396

Claim:
An implantable medical device, comprising: a self-expanding tubular structure comprising at least one biodegradable strand comprising poly(lactic acid-co-glycolic acid) comprising at least about 75 weight percent of lactic acid; and poly(lactic acid-co-caprolactone) at least partially coating said strand; wherein said poly(lactic acid-co-caprolactone) is crosslinked and has a number average molecular weight (Mn) greater than about 30,000 Da; wherein said poly(lactic acid-co-caprolactone) increases the mass of said self-expanding tubular structure by at least about 24 percent; wherein said self-expanding tubular structure is a braided structure comprising between 16 and 48 strands forming an average braid angle of between about 110 degrees and about 135 degrees.
