Abstract

Controlled deployable medical devices that are retained inside a body passage and in one particular application to vascular devices used in repairing arterial dilations, e.g., aneurysms. Such devices can be adjusted during deployment, thereby allowing at least one of a longitudinal or radial re-positioning, resulting in precise alignment of the device to an implant target site.

Claims

1. An apparatus, comprising:

a catheter having a proximal end portion and distal end portion;

a stent arranged on the proximal end portion of the catheter, the stent having an inner surface and an outer surface;

a graft member arranged about the stent member; and

a movable element connected to a torsional member, wherein the torsional member is capable of retracting a portion of the movable element and thereby radially compressing at least a portion of the stent.

2. The apparatus of claim 1, further comprising a tube having a proximal end portion and distal end portion arranged on at least a portion of the stent, wherein at least a portion of the torsional member extends within a portion of the tube.

3. The apparatus of claim 2, wherein the distal end portion of the tube extends to a hub arranged on the distal end portion of the catheter.

4. The apparatus of claim 2, wherein the tube comprises two lumens.

5. The apparatus of claim 1, wherein the movable element comprises a filament.

6. The apparatus of claim 5, wherein the filament comprises a wire.

7. The apparatus of claim 5, wherein the filament comprises a polymer.

8. The apparatus of claim 7, wherein the polymer comprises a fluoropolymer.

9. The apparatus of claim 8, wherein the fluoropolymer comprises polytetrafluoroethylene.

10. The apparatus of claim 9, wherein the polytetrafluoroethylene comprises expanded polytetrafluoroethylene.

11. The apparatus of claim 5, wherein the filament is arranged circumferentially around the graft member and is threaded between adjacent undulations of the stent.

12. The apparatus of claim 1, wherein the tubular graft member is positioned on an inside portion of the stent.

13. The apparatus of claim 2, wherein the tube is positioned on an inside portion of the stent.
