Abstract
Abstract A vascular stent-graft system comprises a stent-graft with an expandable tip and a restraining member disposed about at least a portion of that tip. The restraining member constrains expansion of the tip, even absent contact with a delivery device by which the stent-graft is deployed. Thus, unlike prior art designs, the tip can be partially positioned and at least temporarily freed from the grasp of a deployment device without risk that the tip will be prematurely expand into a potentially undesirable fit in the aorta.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
76 words
A method of vascular treatment comprising: A. inserting into a vascular cavity a stent-graft system comprising i. an expandable tip, ii. a restraining member disposed about at least a portion of the tip, the restraining member constraining expansion of the tip, B. positioning at least the tip and restraining member at a desired location in the cavity, and C. removing the restraining member from the tip of the stent-graft via a motion in a central-to-peripheral direction.
Claim 2
Independent Claim
76 words
A method of vascular treatment comprising: A. inserting into a vascular cavity a stent-graft system comprising i. an expandable tip, ii. a restraining member disposed about at least a portion of the tip, the restraining member constraining expansion of the tip, B. positioning at least the tip and restraining member at a desired location in the cavity, and C. removing the restraining member from the tip of the stent-graft via a motion in a central-to-peripheral direction.
Claim 3
Dependent Claim
27 words
A method according to claim 1 , wherein the restraining member constrains expansion of the tip even absent contact with means by which the stent-graft is deployed.
Claim 4
Dependent Claim
19 words
A method according to claim 1 , wherein step (C) comprises slidably removing the restraining member from the tip.
Claim 5
Dependent Claim
17 words
A method according to claim 1 , wherein the restraining member is detachably affixed to the tip.
Claim 6
Dependent Claim
28 words
A method according to claim 4 , wherein the restraining member is detachably affixed by any a suture, hook, aperture, button, hook-and-loop, and friction seal to the tip.
Claim 7
Dependent Claim
24 words
A method according to claim 1 , wherein step (B) comprises grasping the restraining member in order to position the tip in the cavity.
Claim 8
Dependent Claim
26 words
A method according to claim 1 , wherein step (C) comprises detaching the restraining member from the stent-graft in order to remove it from the tip.
Claim 9
Dependent Claim
30 words
A method according to claim 7 , wherein step (C) comprises any of breaking a suture and detaching a hook in order to remove the restraining member from the tip.
Claim 10
Independent Claim
106 words
A method of treatment of an abdominal aortic aneurysm, comprising of A. inserting a stent-graft into one or more of a patient's aortic artery and iliac artery in a vicinity of the aneurysm, the stent-graft comprising: i. an expandable tip, ii. a restraining member disposed about at least a portion of the tip, the restraining member constraining expansion of the tip, B. positioning at least the tip of the stent-graft and restraining member at a desired location in one or more of the aortic and iliac arteries, and C. removing the restraining member by sliding it from the tip of the stent-graft in a central-to-peripheral direction.
Claim 11
Independent Claim
106 words
A method of treatment of an abdominal aortic aneurysm, comprising of A. inserting a stent-graft into one or more of a patient's aortic artery and iliac artery in a vicinity of the aneurysm, the stent-graft comprising: i. an expandable tip, ii. a restraining member disposed about at least a portion of the tip, the restraining member constraining expansion of the tip, B. positioning at least the tip of the stent-graft and restraining member at a desired location in one or more of the aortic and iliac arteries, and C. removing the restraining member by sliding it from the tip of the stent-graft in a central-to-peripheral direction.
Claim 12
Dependent Claim
27 words
A method according to claim 9 , wherein the restraining member constrains expansion of the tip even absent contact with means by which the stent-graft is deployed.
Claim 13
Dependent Claim
19 words
A method according to claim 9 , wherein step (C) comprises slidably removing the restraining member from the tip.
Claim 14
Dependent Claim
20 words
A method according to claim 9 , wherein step (A) comprises inserting the stent-graft directly into an abdominal aortic aneurysm.
Claim 15
Dependent Claim
22 words
A method according to claim 9 , wherein step (A) comprises pushing the stent-graft into the aneurysm via a translumbar, percutaneous approach.
Claim 16
Dependent Claim
38 words
A method according to claim 13 , wherein step (B) comprises grasping the restraining member with a catheter loop-snare in order to position a tip of the stent-graft into one or more of the aortic and iliac arteries.
Claim 17
