CATHETER SYSTEM FOR EMBOLI CONTAINMENT
First Claim
1. A catheter system, comprising:
- a hollow inner catheter having a proximal end and a distal end;
an occlusion device mounted on the distal end of the inner catheter; and
a main catheter sized to receive the inner catheter such that an outer fluid pathway is formed therebetween for irrigation or aspiration, said main catheter having an occlusion device mounted on a distal end which cooperates with the occlusion device on the inner catheter to form a chamber therebetween, and the main catheter having a dedicated irrigation/aspiration port to permit simultaneous irrigation and aspiration within the chamber.

Abstract
A multi-catheter emboli containment system is disclosed which is adapted to provide at least one pair of optimized paths for irrigation and aspiration fluid flow. Through careful design of the cross-sectional area of these paths, the present system is able to be compactly utilized in even the smaller size blood vessels. The catheter system itself is provided with occlusive devices to form an emboli containment chamber in which irrigation and aspiration occur. The catheter system of the present invention provides an improved emboli containment and removal system which can be utilized in a wide range of vessel diameters. The system is easy to use and can quickly and efficiently evacuate the containment chamber.

21. A catheter system, comprising:
-
a hollow guidewire having a proximal end and a distal end;
an inflatable balloon mounted on the distal end of the guidewire;
an intermediate catheter, wherein at least a portion of said intermediate catheter is positioned over said guidewire such that an inner fluid pathway is formed therebetween and such that the intermediate catheter is slidable to a location proximal to the balloon; and
a main catheter sized to receive the intermediate catheter such that an outer fluid pathway is formed therebetween for irrigation or aspiration, said main catheter having an inflatable balloon mounted on a distal end which cooperates with the balloon on the inner catheter to form a chamber therebetween, and the main catheter having a dedicated irrigation/aspiration port to permit simultaneous irrigation and aspiration within the chamber.
