Abstract

The instant disclosure is directed to devices and methods for deploying a biased occlusion clamp. In addition, the present disclosure includes devices and methods for deploying a biased occlusion clamp using robotics. Moreover, the present disclosure includes devices and methods for reducing the force necessary to open an occlusion clamp without permanently compromising the clamping force of the clamp itself.

Claims

1. An occlusion device comprising:

an occlusion clamp comprising a first beam and a second beam biased toward one another; and

,

an occlusion clamp deployment device comprising a repositionable frame removably coupled to the occlusion clamp, the repositionable frame comprising a plurality of repositionable links that are mounted to one another and are oriented around the occlusion clamp;

wherein the plurality of repositionable links include;

a first link extending along a length of the first beam;

a second link extending along a length of the second beam;

a first series of links concurrently mounted to the first link and the second link; and

,

a second series of links concurrently mounted to the first link and the second link;

wherein the first link, the second link, the first series of links, and the second series of links create a loop around the occlusion clamp; and

wherein the first and second series of links are repositionable with respect to the first link and the second link to vary a spacing between the first and second links.

2. The occlusion device of claim 1, wherein:

the first beam includes a first end coupled to a first end of the second beam by a first occlusion spring; and

,

the first beam includes a second end coupled to a second end of the second beam by a second occlusion spring.

3. The occlusion device of claim 2, wherein the first beam, the second beam, the first occlusion spring, and the second occlusion spring comprise a continuous loop.

4. The occlusion device of claim 1, wherein:

the first series of links comprises at least two links repositionably connected to one another;

the second series of links comprises at least two links repositionably connected to one another; and

,

the repositionable frame includes a tether operatively coupled to the first series of links and the second series of links, the tether being repositionable to vary the spacing between the first and second links.

5. The occlusion device of claim 1, further comprising a deployment shaft operatively coupled to the repositionable frame, wherein:

the first series of links comprises at least two links repositionably connected to one another;

the second series of links comprises at least two links repositionably connected to one another;

the repositionable frame includes a tether operatively coupled to the first series of links and the second series of links, the tether being repositionable to vary the spacing between the first and second links; and

,

at least a portion of the tether is threaded through the deployment shaft and repositionable within the deployment shaft.

6. A method of fabricating an occlusion device, the method comprising mounting an occlusion clamp deployment device to an occlusion clamp, the occlusion clamp comprising a first beam and a second beam biased toward one another, the occlusion clamp deployment device including a counterbias spring biasing the first and second beams of the occlusion clamp away from one another, wherein the biasing of the counterbias spring exerts a force less than a force biasing the first beam and the second beam toward one another.

7. The method of claim 6, wherein:

the first beam includes a first end coupled to a first end of the second beam by a first occlusion spring;

the first beam includes a second end coupled to a second end of the second beam by a second occlusion spring; and

,

the first beam, the second beam, the first occlusion spring, and the second occlusion spring comprise a continuous loop.

8. The method of claim 6, wherein the act of mounting the occlusion clamp deployment device to the occlusion clamp includes removably mounting the occlusion clamp deployment device to the occlusion clamp by using a suture to concurrently mount the occlusion clamp deployment device to the occlusion clamp.

9. An occlusion device comprising:

an occlusion clamp comprising a first beam and a second beam biased toward one another; and

,

an occlusion clamp deployment device including a counterbias spring removably mounted to the occlusion clamp, the counterbias spring biasing the first and second beam of the occlusion clamp away from one another;

wherein the biasing of the counterbias spring exerts a force less than a force biasing the first beam and the second beam toward one another.

10. The occlusion device of claim 9, wherein:

the first beam includes a first end coupled to a first end of the second beam by a first occlusion spring; and

,

the first beam includes a second end coupled to a second end of the second beam by a second occlusion spring.

11. The occlusion device of claim 9, wherein the counterbias spring comprises a continuous loop that includes a pair of torsion springs coupled to one another by a pair of crosspieces.

12. The occlusion device of claim 11, wherein:

a first crosspiece of the pair of crosspieces is mounted to the first beam of the occlusion clamp;

a second crosspiece of the pair of crosspieces is mounted to the second beam of the occlusion clamp; and

,

13. The occlusion device of claim 10, wherein the first beam, the second beam, the first occlusion spring, and the second occlusion spring comprise a continuous loop.

14. The occlusion device of claim 13, wherein the counterbias spring comprises a continuous loop that includes a pair of torsion springs coupled to one another by a pair of crosspieces.

15. The occlusion device of claim 14, wherein:

a first crosspiece of the pair of crosspieces is mounted to the first beam of the occlusion clamp;

a second crosspiece of the pair of crosspieces is mounted to the second beam of the occlusion clamp; and

,
