Abstract

A system and method for joining an end of a tubular prosthesis to the wall of a vessel wherein an anvil is inserted into the vessel through an opening in the vessel wall produced by a cutting surface on the anvil. The anvil is operated via an anvil handle which may extend through the tubular prosthesis. The tubular prosthesis is guided to the opening in the vessel wall whereupon jaws clamp the prosthesis around the anvil. Staples mounted on the jaws engage the anvil and are bent to thereby staple the end of the tubular prosthesis to the vessel wall. A cutting edge may be mounted to the anvil and utilized to create an enlarged hole to permit blood flow into the tubular prosthesis and to permit removal of the anvil from the vessel.

First claim

What is claimed is:

1. A surgical attaching system for joining a tubular prosthesis to a wall of a native vessel of an animate body, comprising: a tubular prosthesis suitable for joining to said wall of said vessel; at least two jaws carried by a first handle, said tubular prosthesis being secured to said at least two jaws, each of said at least two jaws having a first end and a second end opposite the first end, wherein a first hinge is configured to connect said at least two jaws at the first end and a second hinge is configured to connect said at least two jaws at the second end; the second end defined by end sections which are rounded or angular and lead up to the second hinge so that the jaws are configured to staple around an entire circumference of the tubular prosthesis; and an anvil mounted to a second handle, said anvil mounted so as to be moveable through said tubular prosthesis, wherein said first and second handles are configured to operate independent of each other.

2. The surgical attaching system of claim 1 , further comprising a sharp portion of said anvil suitable for making an opening in said vessel, said anvil being sized for insertion through said opening in said vessel.

3. The surgical attaching system of claim 1 , further comprising said at least two jaws being mounted with respect to said anvil for positioning said tubular prosthesis in surrounding relationship to an opening in said vessel.

4. The surgical attaching system of claim 3 , wherein said second handle is configured to be movable inside said tubular prosthesis.

5. The surgical attaching system of claim 1 , wherein said at least two jaws are configured to be pivotally mounted with respect to said first handle.

6. The surgical attaching system of claim 5 , further comprising a fork attached to the first handle and the at least two jaws, the fork configured to effect control of pivotal movement of the at least two jaws.

7. The surgical attaching system of claim 1 , wherein said anvil is adapted for making an opening in said vessel and insertion through said opening in said vessel.

8. The surgical attaching system of claim 7 , further comprising compression surfaces on said at least two jaws, said compression surfaces on said at least two jaws being pivotal to compress a wall of said vessel against opposite sides of said anvil when said anvil is positioned within said vessel.

9. The surgical attaching system of claim 8 , further comprising staples mounted to or adjacent to said compression surfaces for stapling said tubular prosthesis to said wall of said vessel.

10. The surgical attaching system of claim 9 , further comprising a cutting edge movable within said tubular prosthesis to provide an enlarged opening in said wall of said vessel such that said enlarged opening has a diameter approximately similar to an inner diameter of said tubular prosthesis to permit fluid flow through said hole, said anvil being removable through said tubular prosthesis.

11. The surgical attaching system of claim 1 , wherein said tubular prosthesis is woven.

12. A surgical attaching system for joining a tubular prosthesis to a wall of a native vessel of an animate body, comprising:
a tubular prosthesis suitable for joining to said wall of said vessel at a distal end of said prosthesis; at least two jaws attached to a jaws handle, said at least two jaws being movable with respect to each other, said tubular prosthesis being secured to said at least two jaws, each of said at least two jaws having a first end and a second end opposite the first end, wherein a first hinge is configured to connect said at least two jaws at the first end and a second hinge is configured to connect said at least two jaws at the second end; the second end defined by end sections which are rounded or angular and lead up to the second hinge so that the jaws are configured to staple around an entire circumference of the tubular prosthesis; wherein the hinges are positioned at the distal end of said prosthesis such that the jaws are configured to pivot adjacent to the surface of said vessel, staples secured to said at least two jaws, said staples being mounted for stapling said tubular prosthesis to an outer surface of said wall of said vessel; and an anvil attached to an anvil handle, said anvil sized for insertion into said vessel, said at least two jaws being movable to compress said wall of said vessel against said anvil when said anvil is positioned within said vessel for stapling said tubular prosthesis to said vessel, wherein said jaws handle and said anvil handle are configured to operate independent of each other.

13. The surgical attaching system of claim 12 , wherein said at least two jaws are pivotally mounted with respect to each other for compressing said wall of said vessel against opposite sides of said anvil for diametrically opposed application of force against said opposite sides of said anvil to effect said stapling.

14. The surgical attaching system of claim 13 , wherein said jaws handle is configured to be positioned outside of said tubular prosthesis.

15. The surgical attaching system of claim 12 , wherein said anvil handle is configured to be positioned within an interior of said prosthesis.

16. The surgical attaching system of claim 15 , further comprising a cutting edge positioned to produce a fluid flow opening in said wall of said vessel leading into said tubular prosthesis and through which said anvil may be removed through said tubular prosthesis with said anvil handle.

17. The surgical attaching system of claim 12 , further comprising a sharpened end of said anvil for producing an opening in said wall of said vessel for insertion of said anvil into said vessel.

18. The surgical attaching system of claim 17 , further comprising said at least two jaws being mounted with respect to said anvil for positioning said tubular prosthesis on said wall in surrounding relationship to said opening in said vessel.

19. The surgical attaching system of claim 18 , further comprising a cutting edge movable within said tubular prosthesis to enlarge said opening.

20. A surgical attaching system for joining a tubular prosthesis to a wall of a native vessel of an animate body, comprising:
a tubular prosthesis suitable for joining to said wall of said vessel; at least two jaws attached to a jaws handle and pivotal with respect to each other, each of said at least two jaws having a first end and a second end opposite the first end, wherein a first hinge is configured to connect said at least two jaws at the first end and a second hinge is configured to connect said at least two jaws at the second end, said tubular prosthesis being secured to said at least two jaws; an anvil; and an anvil handle for controlling said anvil, wherein said anvil is configured to be insertable through said wall of said vessel whereupon said at least two jaws are pivotal around said anvil to clamp a portion of said wall of said vessel against said anvil, wherein said jaws handle and said anvil handle are configured to operate independent of each other; and a fork attached to the jaws handle and positioned over the at least two jaws, the fork extending in the direction of the at least two jaws and configured to effect control of pivotal movement of the at least two jaws.

21. The surgical attaching system of claim 20 , further comprising staples secured to said jaws for stapling said tubular prosthesis to said vessel.

22. The surgical attaching system of claim 20 , wherein said anvil h
