Appl. No.:

13/458076

Inventors:

Meghan Pearson - Santa Rosa CA, US
Emilie Simmons - Cotati CA, US
Stephen Pearce - Santa Rosa CA, US
Stephannie Rundle - Santa Rosa CA, US
Ana Zavala - Santa Rosa CA, US

Assignee:

MEDTRONIC VASCULAR, INC. - Santa Rosa CA

International Classification:

A61F 2/82

US Classification:

623 135

Abstract:

A circumferentially constraining suture for an endovascular prosthesis having a tubular body and a plurality of stents coupled to the tubular body includes a first thread coupled at a first end to one of the stents and a first thread loop disposed opposite the first end. The first thread extends only partially around a circumference of the tubular body in a radially expanded configuration. A second thread having a second thread loop is interlocked with the first thread loop and extends from the first thread loop around a remainder of the circumference of the tubular body. Pulling the second thread causes the first thread to circumferentially constrain the tubular body to a reduced diameter configuration. A trigger wire inserted through the first thread loop retains the first thread such that the tubular body is in the reduced diameter configuration after removal of the second thread.

US Classification:

623 113, 623 12

Abstract:

A self-expanding main vessel stent-graft includes a trunk portion configured for placement within the abdominal aorta and a bifurcated portion configured for placement above the aortic bifurcation of the common iliac arteries. The trunk portion includes a proximal end section having an anchor stent and a seal stent that accommodates a scallop or open-top fenestration; a suprarenal body section having at least one stent of variable stiffness to accommodate branch vessel prosthesis deployed alongside the main vessel stent-graft; a branch connection section having opposing couplings for connecting the main vessel stent-graft to branch vessel prostheses deployed within the renal arteries; an infrarenal body section having at least one stent of uniform stiffness; and a transition section for transitioning into the bifurcated portion. The main vessel stent-graft is configured to treat short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms in a wide range of patient anatomies.

International Classification:

A61F 2/84

US Classification:

623 112

Abstract:

A reconfigurable delivery system is disclosed having a multi-lumen delivery catheter configuration that permits the delivery and staged release of a self-expanding main vessel stent-graft and a delivery sheath configuration that permits the introduction of various medical devices for the delivery and implantation of various branch vessel stent-grafts that are to be mated with the main vessel stent-graft. A method is disclosed wherein the delivery system is first used in the multi-lumen delivery catheter configuration to deliver and release a main vessel stent-graft that is configured for placement in the abdominal aorta for treatment of short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms and then used in the delivery sheath configuration to facilitate the delivery of branch vessel stent-grafts that are configured to extend from the main vessel stent-graft into a respective renal artery.

The trunk portion includes a proximal end section having an anchor stent and a seal stent that accommodates a scallop or open-top fenestration; a suprarenal body section having at least one stent of variable stiffness to accommodate branch vessel prosthesis deployed alongside the main vessel stent-graft; a branch connection section having opposing couplings for connecting the main vessel stent-graft to branch vessel prostheses deployed within the renal arteries; an infrarenal body section having at least one stent of uniform stiffness; and a transition section for transitioning into the bifurcated portion. The main vessel stent-graft is configured to treat short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms in a wide range of patient anatomies.
