Flexible stent-graft
First Claim
1. A stent graft for implantation in a body lumen comprising a tubular graft having a first stent section comprising reinforcing material formed into a first pattern and a second stent section comprising reinforcing material formed into a second pattern, the first pattern being different from the second pattern, the tubular graft having a first diameter in the region of the first stent section and a second diameter in the region of the first stent section, wherein the first diameter is different from the second diameter.

Abstract
A stent graft is provided which has two stent sections having different functions on, for example, a tubular graft. One stent section preferably comprises a plurality of circumferential reinforcing hoops and the other a Z-stent. The two sections are preferably separated by a spacer section and the tubular graft preferably increases in diameter from the Z-stent section to the hooped section. This enables the stent graft to be compressed radially so that it can be inserted in a catheter for later delivery to a body lumen.

11. A method comprising:
-
a. radially compressing a stent graft having;
(1) a first stent section having a first diameter, and including reinforcing material formed into a first pattern, and (2) a second stent section having a second diameter and including reinforcing material formed into a second pattern, wherein the second diameter is different from the first diameter and the second pattern is different from the first pattern;
b. inserting the compressed stent graft into a catheter having an internal diameter which is less than the diameter of the first stent section of the stent graft. - View Dependent Claims (12)

13. A stent graft for implantation in a body lumen comprising two or more tubular stent sections connected in series along a common axis, wherein:
-
a. at least one of the stent sections is radially expandable from a compressed state, wherein the stent section has decreased diameter when in its compressed state; and
b. each stent section includes patterned reinforcing material, wherein the stent sections have both;
(1) different diameters, and (2) different reinforcing material patterns, when the stent sections are fully expanded. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
