Hypotube endoluminal device and method
First Claim
1. A method of deploying an endoluminal device in a body lumen from a proximal point outside of the body lumen, the method comprising the steps of:
- (a) providing a delivery system comprising a guidewire having an outer diameter, and a self-expanding endoluminal device comprising a plurality of filamentary members attached together, wherein at least one filamentary member is a tubular filamentary member having a gapless cross section at a proximal end of the guidewire and a hollow core for receiving the guidewire and having a straightened configuration for mounting on the guidewire at the proximal end and a shape memory configuration without the guidewire in the hollow core for deployment in the body lumen, the at least one tubular filamentary member comprising a distal end and a proximal extension having a proximal end;
(b) advancing at least the guidewire into the body lumen to a deployment location;
(c) using the guidewire to deploy the tubular filamentary member in its shape-memory configuration with the distal end in the deployment location and the proximal end of the proximal extension outside of the body lumen or in a location readily accessible from outside of the body lumen.

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.
