Hypotube endoluminal device and method
View Patent ↗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.
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.
2. The endoluminal device of claim 1 , wherein the tubular filamentary member hollow core is adapted to permanently contain a substance.
3. The endoluminal device of claim 1 , wherein the tubular filamentary member hollow core is adapted to receive a substance and to elute the substance from the hollow core.
4. The endoluminal device of claim 3 , wherein the tubular filamentary member is coated with a coating material, wherein the coating material comprises (a) a material that the substance within the tubular filamentary member hollow core is capable of leaching through, (b) a material comprising the at least one biologically or pharmacologically active substance, or (c) both (a) and (b).
5. The endoluminal device of claim 1 further comprising a severable connecting element between the proximal extension and the endoluminal device.
6. The endoluminal device of claim 5 , wherein the connecting element is severable through application of a mechanical force originating at or near the proximal end of the proximal extension.
7. The endoluminal device of claim 5 , wherein the connecting element is severable through application of an electric current originating at or near the proximal end of the proximal extension.
8. The endoluminal device of claim 5 , wherein the connecting element is severable through dissolution by injection of a solvent into the tubular filamentary member.
9. The endoluminal device of claim 1 , wherein the endoluminal device comprises a plurality of filamentary members attached together.
10. The endoluminal device of claim 9 , wherein the device comprises a single tubular filamentary member and a plurality of non-tubular filamentary members.
11. An endoluminal device and delivery system for deploying the endoluminal device in a body lumen from a proximal point outside of the body lumen, the endoluminal device and delivery system comprising:
at least one guidewire; and
the endoluminal device of claim 1 .
