Abstract
Disclosed is a self-expanding medical implant for placement within a lumen of a patient. The implant comprises a woven or non-woven structure having a substantially tubular configuration, and is designed to be low-profile such that it is deliverable with a small diameter catheter. The implant has a high recoverability and desired mechanical properties.
Claims25
An implantable medical device, comprising:
- a self-expanding tubular structure comprising at least one strand comprising a first polymer characterized by a modulus of elasticity greater than about 1 GPa;
- and
- a second polymer at least partially and conformally coating said strand, said second polymer being an elastomeric thermoset polymer characterized by a percent elongation to break that is greater than about 150 percent at 37° C.;
- wherein the second polymer increases the mass of said self-expanding tubular structure by at least about 20 percent.

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 75 weight percent of lactic acid;
- and
- poly(lactic acid-co-caprolactine) at least partially coating said strand;
- wherein said poly9lactic acid-co-caprolactone) is cross-linked and has a number average molecular weight (Mn) greater than 30,000 Da;
- wherein said poly(lactic acid co-caprolactone) increases the mass of said self-expanding tubular structure by at least 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 110 degrees and 135 degrees.
