An implantable stent-like device for treating and occluding arteriovascular malformations (AVMs), fistulas, varicose veins or the like. More particularly, this invention relates to an implant body that includes an open-cell shape-transformable polymer structure that provides stress-free means for occluding an AVM without applying additional pressures an any distended walls of the AVM. In one embodiment, the shape-transformable polymer is a shape memory polymer implant body that self-deploys from a temporary shape to a memory shape. In another embodiment, the shape memory polymer structure is capable of a temporary compacted shape for carrying about the struts of an expandable stent for self-deployment to occlude an aneurysm. |
