摘要:
The invention provides an implantable medical device comprising: a structural element, wherein the structural element includes: a continuous phase comprising a first polymer; a discrete phase within the continuous phase, wherein the discrete phase has a second polymer including discrete phase segments; and anchor segments that have substantially the same chemical make up as the first polymer of the continuous phase; wherein at least some of the anchor segments have partially or completely phase-separated from the discrete phase into the continuous phase.
