Abstract

Claims (13)

1. A method comprising:

deploying a first stent-graft within a vessel such that a body portion of the first stent-graft has a first diameter and a waist portion of the first stent-graft has a second diameter less than the first diameter, the body portion of the first stent-graft transitions into the waist portion of the first stent-graft through a transition portion of the first stent-graft, the waist portion of the first stent-graft has a distal end; and deploying a proximal portion of a second stent-graft within the first stent-graft proximal to the waist portion of the first stent-graft to capture the proximal portion of the second stent-graft within the first stent-graft, the proximal portion of the second stent-graft has a proximal end, the proximal portion of the second stent-graft follows a profile of the body portion, the transition portion, and the waist portion of the first stent-graft from the proximal end of the proximal portion of the second stent-graft to the distal end of the waist portion of the first stent-graft, the second stent-graft has a distal portion extending distally from the proximal portion of the second stent-graft, the distal portion of the second stent-graft having a waist portion, the waist portion of the distal portion of the second stent-graft transitions, distally from the distal end of the waist portion of the first stent-graft, into a body portion of the distal portion of the second stent-graft through a transition portion of the distal portion of the second stent-graft, the body portion of the distal portion of the second stent-graft has a third diameter greater than a fourth diameter of the waist portion of the distal portion of the second stent-graft;

wherein the body portion of the first or second stent-graft is expanded more than the waist portion of the first or second stent-graft, respectively, during the deploying of the first or second stent-graft.

2. The method of claim 1 wherein the body portion of the first stent-graft is selectively expandable relative to the waist portion of the first stent-graft.

3. The method of claim 1 wherein the deploying the first stent-graft comprises pressurizing the first stent-graft to cause the expansion.

4. The method of claim 1 wherein the proximal portion of the second stent-graft includes a seated portion.

5. The method of claim 4 wherein an interlock between the first stent-graft and the second stent-graft is created by locating the seated portion of the second stent-graft proximal to the waist portion of the first stent-graft.

6. The method of claim 1 wherein the body portion of the first or second stent-graft comprises first graft material having angled yarns.

7. The method of claim 6 wherein the waist portion of the first or second stent-graft comprises second graft material having perpendicular yarns.

8. The method of claim 1 wherein a diameter of the transition portion of the first stent-graft is less than the first diameter and greater than the second diameter.

9. The method of claim 1 wherein the transition portion of the first stent-graft has a varying diameter transitioning from the first diameter at the body portion of the first stent-graft to the second diameter at the waist portion.

10. The method of claim 1 wherein the body portion extends distally from a proximal end of the first stent-graft to the transition portion, and the waist portion extends proximally from a distal end of the first stent-graft to the transition portion.

11. The method of claim 1 wherein the waist portion of the first stent-graft has a longitudinal length.
