Filed:

Aug 24, 2005

Appl. No.:

11/210636

Inventors:

Arani Bose - New York NY, US
Vikas Gupta - San Leandro CA, US
Sean Donahue - Half Moon Bay CA, US
Delilah Hui - American Canyon CA, US

Assignee:

Penumbra, Inc. - Alameda CA

International Classification:

A61M 29/00
A61B 17/22

US Classification:

606127, 606113

Abstract:

A thromboembolic removal system for treating ischemic stroke includes an elongate member and a receiver on a distal portion of the elongate member. The receiver includes structural members arranged to form a sleeve having a central lumen. A plurality of the structural members form engaging elements having apex regions that extend into the central lumen. During use of the thromboembolic removal system, the receiver is advanced over a body of thromboembolic material within a blood vessel, causing the body to be received into the central lumen, and causing the engaging elements to engage the body within the lumen.

US Classification:

606200, 606159

Abstract:

A thromboembolic removal system for treating ischemic stroke includes an aspiration catheter and an elongate member having a separator on a distal portion of the elongate member. During use of the thromboembolic removal system, the aspiration catheter and elongate member are positioned in a blood vessel, with the elongate member extending through the lumen of the aspiration catheter. Vacuum is applied through the aspiration catheter and the separator is deployed distal to the aspiration catheter into contact with thromboembolic material within a blood vessel. Manipulation of the separator during aspiration can facilitate aspiration by loosening, separating, or softening pieces of thromboembolic material, by removing any clogs or flow restrictions within the lumen of the aspiration catheter, and/or by pushing or plunging loosened material towards and/or into the distal end of the aspiration catheter for subsequent aspiration out of the body.

International Classification:

A61F 2/06

US Classification:

623001150

Abstract:

An aneurysm occlusion device is positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes a tubular element having a lumen surrounded by an occlusive sidewall including a plurality of gaps. The gaps are sufficiently small to cause at least partial occlusion against flow of blood from the blood vessel through the side wall into the aneurysm, but are expandable in response to a fluid pressure differential between a first area inside the lumen and a second area outside the lumen to allow flow of fluid through the side wall between the blood vessel and a side branch vessel.

International Classification:

US Classification:

623 111

Abstract:

An aneurysm occlusion system includes devices positionable within a cerebral blood vessel covering a neck of an aneurysm in the blood vessel. A component device includes an expandable tubular body, an expandable anchor, and a link connecting the body to the anchor. One or more devices deployed using a method according to the invention includes a novel feature that guarantees that the distal high coverage segment aligns with the neck of the aneurysm. A single device or multiple devices, used in conjunction with an embolic material or coil, may be combined to form a system according to the invention. When positioned and deployed strategically either alone or with a second device utilizing a method according to the invention, the system has a high coverage region covering a neck of an aneurysm, and a gap between the system and healthy vessel. The system and method prevent blood flow into an aneurysm while permitting blood flow through healthy vessel.
