Filed:

Mar 15, 2000

Appl. No.:

09/525778

Inventors:

Samuel M. Shaolian - Newport Beach CA
Gilbert Madrid - Laguna Niguel CA
Thanh Van Nguyen - Irvine CA
Trinh Van Pham - Santa Ana CA

Assignee:

Endologix, Inc. - Irvine CA

International Classification:

A61F 206

US Classification:

623 111

Abstract:

A deployment catheter for deploying a tubular endoluminal vascular prosthesis includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy the prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. In one embodiment, a reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section. In another embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central-core.

International Classification:

A61F 206

US Classification:

623 111, 623 123

Abstract:

Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.

Assignee:

Endologix, Inc. - Irvine CA

International Classification:

A61F 206

US Classification:

623 135

Abstract:

The present invention relates to the endoluminal repair of abdominal aortic aneurysms at the aortic and iliac bifurcation. In particular, a deployment system and graft are disclosed for deploying the bifurcated graft within both iliac branches, as well as the aortic trunk, from a single vascular access.

International Classification:

A61F 2/84

US Classification:

623 123, 623 111

Abstract:

A graft deployment system, comprises an elongate, flexible catheter body, having a proximal end and a distal end and comprising an outer sheath and an inner core that is axially moveable with respect to the outer sheath. A main vessel graft restraint comprising a first peelable cover for restrains a main vessel portion of a graft. In a bifurcated graft, a first branch vessel graft restraint restrains a first branch vessel portion of the graft. A second branch vessel graft restraint restrains a second branch vessel portion of the graft. The first peelable cover is coupled to a main branch release element and wherein each of the main vessel graft restraint, first branch vessel graft restraint, and the second branch vessel graft restraint are positioned within the catheter body in a graft loaded condition.
