摘要:
This invention is directed to methods for treating aneurysms wherein the aneurysmal sac is filled with a non-particulate agent or plurality of such agents and/or with a fluid composition which solidifies in situ. Filling of the aneurysmal sac employs sufficient amount of the non-particulate agent or plurality of such agents and/or the fluid composition to inhibit blood flow into the aneurysm sac. In addition, the methods of this invention also provide for non-endogenous isolation of the parent artery proximal and distal to the aneurysmal sac from systemic blood flow of the treated mammal. The combination of these features provides for treatment of the aneurysmal sac while, at the same time, inhibiting aneurysm formation and/or regrowth in the diseased portions of the arterial wall proximal and distal to the treated aneurysm.

This invention is directed to novel methods for gynecologic embolotherapy by endovascular embolization with a fluid embolic composition which in situ in the blood vessel forms a coherent solid mass.
摘要:
Disclosed are compositions suitable for use in embolizing blood vessels which compositions comprise a polymer, a biocompatible solvent and a contrast agent. The polymer is selected from the group consisting of polyacrylonitrile, polyvinylacetate, cellulose acetate butyrate, nitrocellulose and copolymers of urethane/carbonate and copolymers of styrene/maleic acid.

Disclosed are novel methods for embolizing blood vessels which are particularly suited for treating vascular lesions via catheter delivery of an embolic composition comprising a biocompatible polymer and an embolic solvent.
摘要:
A liquid embolic delivery system is provided for trapping an injected liquid embolic composition to prevent the liquid embolic from solidifying or otherwise passing outside of an embolization area. The delivery system includes a catheter for delivery of a liquid embolic composition and a containment member positioned at a distal end of the catheter which is shaped to trap the liquid embolic composition delivered through the lumen of the catheter. The containment member is formed as a brush, nest, sponge, swab, flexible sack, or other shape into and around which the liquid embolic composition is injected. The liquid embolic composition is trapped or meshes with the containment member during solidification containing the liquid embolic and preventing the embolic composition from passing into the blood stream.

Disclosed are novel syringes (10) and catheters (34) for delivering compositions which form solid masses in vivo. These syringes (10) and catheters (34) are particularly useful for delivering embolizing compositions intravascularly.
