Abstract
An endovascular device for occluding a vascular aneurysm is disclosed. The device includes a polymeric shell member that, in one embodiment, may be constructed from a bioactive and biocompatible polyurethane-diol-glycosaminoglycan copolymer, and a liquid embolic agent. The copolymer is sufficiently flexible and strong for endovascular delivery into a vascular aneurysm and for use as a polymeric shell for receiving the liquid embolic agent. Upon activation inside of the polymeric shell within the aneurysm, the liquid embolic agent solidifies enabling biological isolation of the aneurysm and improved patient outcomes.
