Filed:

Sep 3, 2003

Appl. No.:

10/653812

Inventors:

Richard J Morrill - Billerica MA, US
John R. Fagan - Pepperell MA, US
David O. Williams - Barrington RI, US

Assignee:

Advanced Vascular Technologies LLC - Barrington RI

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

An improved arterial catheter device for capturing emboli within the aorta and other arteries is described. The system typically includes an elongated catheter member bearing a filtration apparatus disposed at its the distal region, comprising a filter membrane and a mechanism for deploying and collapsing the filter. For reliable deployment, the deployment mechanism comprises at least one pair of struts, one being a compression strut and the other a tension strut. In use, the catheter is positioned so that the filter membrane is down stream from the possible embolic source and upstream from any vital organs of concern. When deployed the filter membrane will capture emboli from the blood stream, and upon filter removal will extract the emboli from the patient.

Assignee:

C. R. Bard, Inc. - Murray Hill NJ

International Classification:

A61M 2900

US Classification:

604 96

Abstract:

A balloon dilatation catheter adapted for use in percutaneous transluminal coronary angioplasty has an integral guidewire. The balloon and its supporting members are not attached to the guidewire at their distal ends. The supporting members are attached at their proximal ends to the guidewire. The guidewire has an increased freedom of rotational movement and the balloon and its supporting members do not adversely twist about the guidewire.
