1. A method of making a stent-graft, comprising:
- providing a self-expanding stent having a collapsed configuration with a first diameter and an expanded configuration with a second diameter greater than the first diameter, the stent including a polymeric coating on at least an inner surface;
disposing a graft on a mandrel having a third diameter greater than the second diameter; and
contacting an outer surface of the graft with the coated inner surface of the stent, the stent applying a compressive force to the graft.

Abstract
A method of making a stent-graft includes providing a self-expanding stent having a collapsed configuration with a first diameter and an expanded configuration with a second diameter greater than the first diameter, the stent including a polymeric coating on at least an inner surface, disposing a graft on a mandrel having a third diameter greater than the second diameter, and contacting an outer surface of the graft with the coated inner surface of the stent, the stent applying a compressive force to the graft.

16. A method of making a stent-graft, comprising:
-
providing a self-expanding stent having a collapsed configuration with a first diameter and an expanded configuration with a second diameter greater than the first diameter, the stent including a polymeric material on at least a portion of an inner surface; disposing an ePTFE graft on a mandrel having a third diameter about 1 mm greater than the second diameter; placing the stent onto the graft by expanding the stent to a fourth diameter greater than the third diameter, positioning the stent over the graft and releasing the stent; and heating the stent-graft.

-
providing a self-expanding stent having a collapsed configuration with a first diameter and an expanded configuration with a second diameter greater than the first diameter, the stent including a polymeric coating on at least an inner surface; disposing an ePTFE graft on a mandrel having a third diameter greater than the second diameter; expanding the stent to a fourth diameter greater than the third diameter, positioning the stent over the graft and releasing the stent, the coated inner surface of the stent contacting an outer surface of the ePTFE graft; wrapping ePTFE tape about an outer surface of the stent under tension; and removing the ePTFE tape prior to subjecting the stent-graft to a heating step. - View Dependent Claims (18, 19, 20)
