Abstract

An occlusion clamp including: (a) an occlusion tongs including a primary spring coupling a first longitudinal arm to a second longitudinal arm, the first longitudinal arm including a first linear occlusion surface configured to be parallel to and overlap a second linear occlusion surface of the second longitudinal arm, each of the first and second longitudinal arms having a free distal end; and, (b) a secondary spring removably coupled to the occlusion tongs.

First claim

What is claimed is:

1. An occlusion clamp comprising:
an occlusion tongs including a primary spring coupling a first longitudinal arm to a second longitudinal arm, the primary spring including a fold interposing the first and second longitudinal arms, the first longitudinal arm including a first linear occlusion surface configured to be parallel to and overlap a second linear occlusion surface of the second longitudinal arm, each of the first and second longitudinal arms having a free distal end; and,
a secondary spring removably coupled to the occlusion tongs.

2. The occlusion clamp of claim 1 , wherein the first longitudinal arm, the primary spring, and the second longitudinal arm are integrated.

3. The occlusion clamp of claim 1 , wherein:
the first longitudinal arm includes a first trench extending longitudinally along a majority of a length of the first longitudinal arm;
the second longitudinal arm includes a second trench extending longitudinally along a majority of a length of the second longitudinal arm;
at least a first portion of the secondary spring is configured engage the first trench to removably couple the secondary spring to the occlusion tongs; and,
at least a second portion of the secondary spring is configured to engage the second trench to removably couple the secondary spring to the occlusion tongs.

4. The occlusion clamp of claim 3 , wherein the first trench includes a first plurality of cavities each configured to potentially receive the first portion of the secondary spring to maintain a relative position of the secondary spring with respect to the first longitudinal arm.

5. The occlusion clamp of claim 4 , wherein the second trench includes a second plurality of cavities each configured to potentially receive the second portion of the secondary spring to maintain a relative position of the secondary spring with respect to the second longitudinal arm.

6. The occlusion clamp of claim 4 , wherein the first plurality of cavities is spaced apart from one another.

7. The occlusion clamp of claim 5 , wherein the first plurality of cavities is spaced apart from one another and the second plurality of cavities are spaced apart from one another.

8. The occlusion clamp of claim 1 , wherein:
the first longitudinal arm includes a first projection extending longitudinally along a majority of a length of the first longitudinal arm;
the second longitudinal arm includes a second projection extending longitudinally along a majority of a length of the second longitudinal arm;
at least a first portion of the secondary spring is configured to engage the first projection to removably couple the secondary spring to the occlusion tongs; and,
at least a second portion of the secondary spring is configured to engage the second projection to removably couple the secondary spring to the occlusion tongs.

9. The occlusion clamp of claim 8 , wherein the first projection comprises a first plurality of projections each configured to potentially engage the first portion of the secondary spring to maintain a relative position of the secondary spring with respect to the first longitudinal arm.

10. The occlusion clamp of claim 9 , wherein the second projection comprises a second plurality of projections each configured to potentially engage the second portion of the secondary spring to maintain a relative position of the secondary spring with respect to the second longitudinal arm.

11. The occlusion clamp of claim 9 , wherein the first plurality of projections is spaced apart from one another.

12. The occlusion clamp of claim 10 , wherein the first plurality of projections is spaced apart from one another and the second plurality of projections is spaced apart from one another.

13. The occlusion clamp of claim 1 , wherein:
the first longitudinal arm includes at least one of a first cavity and a first projection extending longitudinally along a majority of a length of the first longitudinal arm;
the second longitudinal arm includes at least one of a second cavity and a second projection extending longitudinally along a majority of a length of the second longitudinal arm;
at least a first portion of the secondary spring is configured to engage at least one of the first cavity and the first projection to removably couple the secondary spring to the occlusion tongs; and,
at least a second portion of the secondary spring is configured to engage at least one of the second cavity and the second projection to removably couple the secondary spring to the occlusion tongs.

14. The occlusion clamp of claim 13 , wherein:
the first projection comprises a first plurality of projections each configured to potentially engage the first portion of the secondary spring to maintain a relative position of the secondary spring with respect to the first longitudinal arm; and,
the second projection comprises a second plurality of projections each configured to potentially engage the second portion of the secondary spring to maintain a relative position of the secondary spring with respect to the second longitudinal arm.

15. The occlusion clamp of claim 14 , wherein:
the first plurality of projections is spaced apart from one another; and,
the second plurality of projections is spaced apart from one another.

16. The occlusion clamp of claim 13 , wherein:
the first cavity comprises a first plurality of cavities each configured to potentially engage the first portion of the secondary spring to maintain a relative position of the secondary spring with respect to the first longitudinal arm; and,
the second cavity comprises a second plurality of cavities each configured to potentially engage the second portion of the secondary spring to maintain a relative position of the secondary spring with respect to the second longitudinal arm.

17. The occlusion clamp of claim 16 , wherein:
the first plurality of cavities is spaced apart from one another; and,
the second plurality of cavities is spaced apart from one another.

18. The occlusion clamp of claim 1 , wherein:
the secondary spring comprises a discontinuous ring having a first end and a second end;
the first end is spaced apart from the second end;
the first end is mounted to the first longitudinal arm; and,
the second end is mounted to the second longitudinal arm.

19. The occlusion clamp of claim 18 , wherein:
the first end includes a first planar surface;
the second end includes a second planar surface; and,
the first planar surface extends parallel to the second planar surface.

20. The occlusion clamp of claim 18 , wherein:
the first longitudinal arm includes a first arcuate boundary defining a first arcuate depression;
the second longitudinal arm includes a second arcuate boundary defining a second arcuate depression; and,
the primary spring interposes the first arcuate boundary and the second arcuate boundary.

21. The occlusion clamp of claim 1 , wherein:
the first longitudinal arm, the primary spring, and the second longitudinal arm are fabricated from at least one of a polymer, a composite, concrete, a metal, wood, and a ceramic;
the secondary spring is fabricated from at least one of a polymer, a composite, concrete, a metal, wood, and a ceramic.
