Vascular delivery system and method
First Claim
1. A device for deploying a stent-graft within a body lumen comprising:
- an outer tubular member defining an outer lumen;
an intermediate tubular member at least partially disposed within the outer lumen and configured to move axially therein, wherein the intermediate tubular member defines an intermediate lumen;
an inner tubular member at least partially disposed within the intermediate lumen and configured to move axially therein;
a self-expanding stent-graft disposed in the outer lumen and at least partially overlying the intermediate member, wherein the stent-graft is configured to move axially in cooperation with the intermediate member;
a stent lock substantially disposed from a distal end to a proximal end thereof directly on the intermediate tubular member, wherein the stent lock is configured to releasably couple the stent-graft and the intermediate tubular member and is configured to be cylindrically shaped in an unconstrained configuration; and
a tubular member lock configured to releasably couple the inner tubular member and the outer tubular member such that, when the inner tubular member and the outer tubular member are coupled, movement of the outer tubular member in an axial direction results in movement of the inner tubular member in the axial direction with respect to the intermediate tubular member so as to deploy the stent-graft.

Abstract
A delivery device and method for deploying a stent-graft within a body lumen of a patient are provided. According to one embodiment, the delivery device includes a tubular member lock that couples an outer tubular member of the device with an inner tubular member, such that as the outer tubular member is retracted to deploy the stent-graft, the distal-most end of the delivery device is also retracted. In one embodiment, the delivery device also includes a stent lock disposed on an intermediate tubular member that is configured to releasably couple the stent-graft and the intermediate tubular member. The inner tubular member and the outer tubular member are configured to be coupled to one another such that movement of the outer tubular member results in movement of the inner tubular member with respect to the intermediate tubular member so as to deploy the stent-graft.

19. A method for deploying a self-expanding stent-graft within a body lumen comprising:
-
providing a device comprising; an outer tubular member defining an outer lumen; an intermediate tubular member at least partially disposed within the outer lumen, wherein the intermediate tubular member defines an intermediate lumen; an inner tubular member at least partially disposed within the intermediate lumen; a self-expanding stent-graft disposed in the outer lumen and at least partially overlying the intermediate member, wherein the stent-graft is configured to move axially with the intermediate member; and a stent lock substantially disposed from a distal end to a proximal end thereof directly on the intermediate tubular member, wherein the stent lock is configured to releasably couple the stent-graft and the intermediate tubular member and is configured to be cylindrically shaped in an unconstrained configuration; positioning the device within a body lumen; locking the inner tubular member to the outer tubular member; and retracting the outer tubular member and the inner tubular member with respect to the intermediate tubular member, thereby deploying the stent-graft. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
