Abstract

A surgical apparatus comprises a surgical staple for treating tissues of a patient in a surgical procedure. The surgical staple is deformable from a first configuration (e.g., an undeployed configuration) to a second configuration (e.g., a deployed configuration) in accordance with embodiments of the present invention. The surgical staple includes a first leg and a second leg, wherein said surgical staple substantially resembles a V-shape or a suture needle in the first configuration and substantially forms a D-shape in the second configuration in accordance with embodiments of the present invention.

First claim

What is claimed is:

1. A surgical apparatus for treating tissues comprising one or more surgical staples, each of the one or more surgical staples comprising:
a first leg comprising a first end and a second end opposite the first end;
a second leg comprising a third end attached to the first end of the first leg, and a fourth end opposite the third end; and
a notch defined in and extending completely through the second end of the first leg,
wherein the second leg is deformable relative to the first leg to close the staple,
wherein the second leg is deformable relative to the first leg to a first configuration, in which the fourth end of the second leg is outside of the notch, and
wherein the second leg is deformable relative to the first leg to a second configuration, in which the fourth end of the second leg travels through the notch, so as to avoid interference between the first leg and the second leg.

2. The surgical apparatus of claim 1 , wherein in the first configuration the first leg and the second leg of the surgical staple form a substantially V-shape.

3. The surgical apparatus of claim 1 , wherein in the first configuration the first leg of the surgical staple is substantially straight and the second leg of the surgical staple is substantially curved.

4. The surgical apparatus of claim 1 , wherein in the second configuration the first leg of the surgical staple remains substantially straight and the second leg of the surgical staple remains substantially curved.

5. The surgical apparatus of claim 1 , wherein deployment of said one or more surgical staples is done by said surgical apparatus and includes deforming said one or more surgical staples from the first configuration to the second configuration, wherein deforming said one or more surgical staples involves deforming said second leg relative to the said first leg.

6. The surgical apparatus of claim 1 , wherein in the second configuration, the first leg and the second leg of the one or more surgical staples form a substantially D-shape configuration.

7. The surgical apparatus of claim 1 , wherein the first configuration conforms to a V-shape and the second configuration conforms to a D-shape.

8. The surgical apparatus of claim 1 , wherein the fourth end of the second leg is conical.

9. The surgical apparatus of claim 1 , wherein the first leg and the second leg define a first distance therebetween when the second leg is in the first configuration, and a second distance therebetween when the second leg is in the second configuration.

10. The surgical apparatus of claim 9 , wherein the second distance between the first leg and the second leg is less than the first distance between the first leg and the second leg.

11. The surgical apparatus of claim 1 , wherein the second leg is deformable relative to the first leg to a third configuration between the first configuration and the second configuration.

12. The surgical apparatus of claim 1 , wherein the fourth end of the second leg is disposed inside the notch in the second configuration.

13. The surgical apparatus of claim 1 , wherein the fourth end of the second leg is passed completely through the notch in the second configuration.
