FOAM MATRIX EMBOLIZATION DEVICE

摘要

The present invention relates to a medical device for placement at a predetermined location within a passageway of the human body, and more particularly, relates to a flexible embolization device which may be delivered by a cathet er to a pre-selected position within a blood vessel to thereby embolize a blood vess el or a blood vessel defect, such as an aneurysm or fistula. Specifically, the embolizatio n device comprises an elongated coil having a lumen, the coil and lumen being at leas t partially embedded in an elongated foam member comprising, in some embodiments, a flexible, biodegradable, water insoluble, open, interconnecting-cell foam material having embolic characteristics, and capable of allowing cell proliferation into the open ce ll foam interior.
