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 catheter to a pre-selected position within a blood vessel to thereby embolize a blood vessel or a blood vessel defect, such as an aneurysm or fistula. Specifically, the embolization device comprises an elongated coil having a lumen, the coil and lumen being at least 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 cell foam interior.
