Hypotube endoluminal device and method
First Claim
1. A self-expanding endoluminal device comprising at least one tubular filamentary member having a proximal end and a hollow core for receiving a guidewire and a graft attached at or near a distal end of the at least one tubular filamentary member, the graft to be deployed and extend proximally from a shape memory configuration at the distal end of the at least one tubular filamentary member, the tubular filamentary member having a straightened configuration for mounting on the guidewire at the proximal end and the shape memory configuration without the guidewire in the hollow core at the distal end, the shape memory configuration attached at or near a distal end of the graft to secure the graft inside a body lumen, the tubular filamentary member comprising a proximal extension having a length sufficient for a proximal end of the extension to be positioned in a location outside of the body lumen or in a location readibly accessible from outside of the body lumen with the distal end of the tubular filamentary member in the deployment location.

Abstract
A self-expanding endoluminal device comprising a tubular filamentary member having a hollow core for receiving a guidewire, the tubular member having a straightened configuration with the guidewire in the hollow core, a shape memory configuration without the guidewire in the hollow core, and an extension, optionally severable, accessible from outside of the body. The hollow core may be adapted to contain and elute or permanently contain a substance, which may be injected through the extension. A delivery system includes the guidewire, and a deployment method includes deployment with a proximal end of the extension accessible from outside of the body.
