Abstract

The present invention is comprised of an apparatus for stapling graft material to a vessel wall comprising a stapling device, a balloon catheter, a sheath, and an inflation means.

Claims

1. An apparatus for stapling graft material to a vessel wall comprising in combination:

a stapling device, said stapling device comprising an expandable member and a tube, said tube having a proximal end and a central lumen, said expandable member being integrally connected to said proximal end of said tube, said expandable member further having an upper surface and a stapling surface which are integrally connected to define a closed, substantially hollow structure, said hollow structure communicating with said central lumen of said tube;

a balloon catheter, said balloon catheter being configured for insertion through said central lumen of said tube and into said expandable member for activation of said stapling device; and

an inflation means for inflating said balloon catheter.

2. An apparatus according to claim 1 wherein said stapling surface comprises one or more capsules;

a magnetic coil within each capsule; and

a means for applying and releasing a magnetic charge to said coil.

3. An apparatus according to claim 2 wherein said means for applying and releasing a magnetic charge to said coil comprises a conductive wire in contact with said magnetic coils within each capsule.

4. An apparatus according to claim 3 wherein said tube further comprises an inner surface and an outer surface, and said wire passes between said inner surface and said outer surface.

5. An apparatus according to claim 2 further comprising one or more pins positioned within each capsule.

6. An apparatus according to claim 5 wherein said one or more pins are comprised of a head and insertion portion;

said insertion portion having a proximal and distal end;

said proximal end of said insertion portion integral with said head;

said distal end of said insertion portion in a hook shape for affixing said pin in position after deployment.

7. An apparatus according to claim 1 wherein said upper surface is stretchable.

8. An apparatus according to claim 1 wherein said balloon catheter comprises a proximal end, an inflatable/deflatable balloon integral with said proximal end, a first lumen for passing said balloon catheter over a guide wire, and a second lumen in fluid communication with said balloon.

9. An apparatus according to claim 1 where said inflation means is a syringe.

10. An apparatus according to claim 1 further comprising a sheath.

11. An apparatus according to claim 10 wherein said sheath is retractable.

12. An apparatus according to claim 11 wherein said sheath is comprised of a fillable space and a ring.
