Abstract

An exemplary surgical apparatus may include a surgical staple deformable from a first configuration to a second, deployed configuration, where the surgical staple includes a first leg and a second leg; where in the second, deployed configuration the surgical staple forms substantially a D-shape. Another exemplary surgical apparatus may include a feeder belt; a surgical staple deformable from a first configuration to a second, deployed configuration, where the surgical staple includes a first leg and a second leg connected to the first leg, where one end of the first leg is frangibly affixed to the feeder belt and one end of said the leg is free; where in the second, deployed configuration the surgical staple forms substantially a D-shape. An exemplary method of treating tissue may include providing a surgical staple; urging the surgical staple into tissue, while the surgical staple has a first shape; and deforming the surgical staple into substantially a D-shape.

Claims (22)

1. A surgical apparatus, comprising:

a surgical staple deformable from a first configuration to a second, deployed configuration, said surgical staple including a first leg and a second leg, wherein, in said second, deployed configuration, said surgical staple forms substantially a D-shape; and

a feeder belt to which surgical staple is frangibly affixed, wherein one end of said first leg is affixed to said feeder belt, and one end of said second leg is free, and wherein said ends are closer to one another in said second, deployed configuration than in said first configuration.

2. The surgical apparatus of claim 1 , wherein said ends contact one another in said second configuration.

3. The surgical apparatus of claim 1 , wherein said surgical staple is plastically deformable from said first configuration to said second configuration.

4. The surgical apparatus of claim 1 , wherein in said first configuration, said first leg of said surgical staple is substantially straight, and said second leg of said surgical staple is at least partially curved.

5. The surgical apparatus of claim 1 , wherein in said second, deployed configuration, said surgical staple forms a completely closed D-shape.

6. The surgical apparatus of claim 1 , wherein said surgical staple is generally V-shaped in said first configuration.

7. The surgical apparatus of claim 1 , wherein said surgical staple includes a continuously curved segment in said first configuration.

8. A surgical apparatus, comprising:

a feeder belt;

a surgical staple deformable from a first configuration to a second, deployed configuration, said surgical staple including a first leg and a second leg connected to said first leg, wherein one end of said first leg is frangibly affixed to said feeder belt and one end of said second leg is free;

wherein in said second, deployed configuration said surgical staple forms substantially a D-shape, and wherein said ends contact one another in said second configuration.

9. The surgical apparatus of claim 8 , wherein in said first configuration, said first leg of said surgical staple is substantially straight, and said second leg of said surgical staple is at least partially curved.

10. The surgical apparatus of claim 8 , wherein said surgical staple is plastically deformable from said first configuration to said second configuration.

11. The surgical apparatus of claim 8 , further comprising at least one additional differently sized surgical staple affixed to said feeder belt.

12. A method of treating tissue, comprising:

urging a surgical staple into tissue, while said surgical staple has a first shape;

deforming said surgical staple from said first shape into a second, deployed configuration comprising substantially a D-shape; and

breaking said surgical staple from a feeder belt to which said staple is frangibly affixed, after said deforming, wherein one end of a first leg of said staple is affixed to said feeder belt before said breaking, and wherein one end of a second leg of said staple is free before said breaking, and wherein said ends are closer to one another in said second configuration than in said first configuration.

13. The method of claim 12 , wherein said first shape is generally V-shaped.

14. The method of claim 12 , wherein said deforming is plastically deforming.
