Kink resistant endovascular graft
First Claim
1. A tubular intracorporeal device comprising a longitudinal section which comprises a plurality of circumferential radial support members with a substantially constant longitudinal spacing between the circumferential radial support members that is about 50 to about 200 percent of a longitudinal thickness of the circumferential radial support members.

Abstract
An intracorporeal device, such as an endovascular graft, having a tubular section with circumferential or helical radial support members. The radial support members may be inflatable channels which support the tubular structure of the graft and which are appropriately sized and longitudinally spaced to prevent or reduce kinking of the tubular structure upon bending of the tubular structure.

- 26. An endovascular graft section comprising a plurality of circumferential inflatable channels having a longitudinal spacing between a first segment of a first circumferential inflatable channel and an adjacent segment of a second circumferential inflatable channel that is about 50 to about 200 percent of a longitudinal thickness of the first segment when the first segment is in an expanded state.
- 35. An endovascular graft section comprising a helical inflatable channel having a longitudinal spacing between a first segment of the helical inflatable channel and an adjacent second segment of the helical inflatable channel disposed longitudinally from the first segment that is about 50 to about 200 percent of a longitudinal thickness of the first segment when the helical inflatable channel is in an expanded state.
