Abstract

A tissue staple that includes a pair of legs arranged generally parallel to one another connected by a pair of tabs. The tabs define an arc that extends distally from the proximal ends of the legs, and further define a slot between the tabs. The distal end of the leg may include a forked portion that defines two or more tissue piercing prongs. The location of the fork also may define a tissue stop. The legs may also include an indent that bends inwardly toward an indent formed on the other leg.

Claims

1. A tissue staple, comprising:

a pair of legs connected to a pair of tabs, said legs arranged generally parallel to one another, and each said leg comprising an indent portion bending inwardly toward one another;

said tabs forming an arc that extends distally from the proximal ends of said legs, and said tabs defining a slot therebetween.

2. A staple as claimed in claim 1, said legs further comprising a fork section on the distal end of said leg, said fork section defining a plurality of tissue-piercing members.

3. A staple as claimed in claim 2, wherein said fork section defining a tissue stop.

4. A staple as claimed in claim 1, said tab having a U-shape extending distally from the proximal ends of said legs.

5. A staple as claimed in claim 1, wherein said legs and tabs being formed in a unitary fashion of a deformable biocompatible and/or bioabsorbable material.

6. A tissue staple, comprising:

a pair of legs arranged generally parallel to one another, said legs connected together at the proximal ends thereof by a pair of tabs, and having fork section on the distal end of said leg, said fork section defining a plurality of tissue-piercing members;

said tabs forming an arc extending distally from the proximal ends of said legs.

7. A staple as claimed in claim 6, wherein said fork section defining a tissue stop.

8. A staple as claimed in claim 6, said tab having a U-shape extending distally from the proximal ends of said legs.

9. A staple as claimed in claim 6, wherein said tabs defining a slot therebetween.

10. A staple as claimed in claim 6, wherein said legs and tabs being formed in a unitary fashion of a deformable biocompatible and/or bioabsorbable material.

11. A staple as claimed in claim 6, each said leg further comprising an indent portion bending inwardly toward one another.

12. A tissue staple, comprising:

a pair of legs arranged generally parallel to one another, and each said leg comprising an indent portion bending inwardly toward one another and a fork section on the distal end of each said leg, said fork section defining a plurality of tissue-piercing members; and

a pair of tabs connected to the proximal ends of said legs, said tabs forming an arc that extends distally from the proximal ends of said legs and defining a slot between said tabs.

13. A staple as claimed in claim 12, wherein said fork section defining a tissue stop.

14. A staple as claimed in claim 12, said tab having a U-shape extending distally from the proximal ends of said legs.

15. A staple as claimed in claim 12, wherein said legs and tabs being formed in a unitary fashion of a deformable biocompatible and/or bioabsorbable material.
