Abstract

Method and apparatus for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring of the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners at least one prosthesis end, usually as each end of the prosthesis. The fasteners are usually helical fasteners which are delivered from a helical track in the fastener applier by rotation with a rotator wire. The fasteners will be applied singly, typically in circumferentially spaced-apart patterns about the interior of each end of the prosthesis.

Claims

1. An intraluminal fastener applier comprising:

a tubular body with a deflectable distal end;

an obturator positioned within a lumen of the tubular body, wherein the obturator comprises a lumen configured to have a guidewire therein, the obturator being conical;

a stabilizer configured to engage a blood vessel wall to hold the distal end of the tubular body in place eccentrically within the blood vessel, the entire stabilizer being proximal of the distal end of the tubular body when the stabilizer is engaged with the blood vessel wall, the stabilizer being configured to be positioned for use when the obturator is removed;

a control handle at a proximal end of the tubular body having controls to separately deflect the distal end, and deploy the stabilizer that holds the deflected distal end in place; and

a fastener delivery device configured to advance a fastener from the distal end into the blood vessel wall engaged by the distal end.

2. An intraluminal fastener applier as in claim 1, wherein the fastener delivery device is introducable through the tubular body and carries at least one fastener.

3. An intraluminal fastener applier as in claim 2, wherein the fastener delivery device comprises a flexible shaft which carries a single helical fastener at its distal end.

4. An intraluminal fastener as in claim 3, wherein the flexible shaft has a helical track which carries the helical fastener and a rotator wire that engages and rotates the helical fastener to cause advancement from the distal end of the body.

5. An intraluminal fastener applier as in claim 1, wherein the stabilizer is located on an outer surface of the tubular body.

6. An intraluminal fastener applier as in claim 1, wherein the stabilizer is inflatable.

7. An intraluminal fastener applier comprising:

a tubular body with a deflectable distal end;

an obturator positioned within a lumen of the tubular body, wherein the obturator comprises a lumen configured to have a guidewire therein, the obturator being conical;

a stabilizer configured to engage a blood vessel wall to hold the distal end of the tubular body in place, the stabilizer being spring-loaded and configured to be positioned for use when the obturator is removed;

a control handle at a proximal end of the tubular body having a control to deflect the distal end; and

a fastener delivery device configured to advance a fastener from the distal end into the blood vessel wall engaged by the distal end.

8. An intraluminal fastener applier as in claim 7, wherein the obturator extends past the distal end of the tubular body.
