Balloon assisted occlusion of aneurysms

摘要

A catheter and related methods for percutaneous treatment of an aneurysm. The present catheters include an outlet for deploying an occluding agent; and a deflector for deflecting the occluding agent. A second deflector may be provided to cooperate with the first deflector. One or both of the deflectors may each include an inflatable balloon. The occluding agent may include a length of wire.

1. A catheter for percutaneous treatment of an aneurysm, comprising:
a first stem, a second stem, and a third stem; an outlet configured to deploy an occluding agent comprising a length of wire, wherein the second stem comprises the outlet; a first deflector for deflecting said occluding agent into said aneurysm, wherein the first stem comprises the first deflector; a second deflector, wherein the third stem comprises the second deflector; and the occluding agent; wherein said first and second deflectors are configured to be actuatable selectively and/or to a variable extent so as to cooperatively adjust the orientation of the second stem and thereby to adjust the at least one of the position and orientation of said outlet; and wherein said first deflector is configured to deflect said occluding agent back into said aneurysm after it has been deflected by the inside of said aneurysm.
