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 (23)

1 . A left atrial appendage occlusion device comprising:

a first beam and a second beam biased toward one another by a first spring coupled thereto, wherein the first and second beams are covered by a fabric, the fabric coupled to a first fabric pocket and a second fabric pocket, wherein the first fabric pocket extends parallel to a longitudinal axis of the first beam and the second fabric pocket extends parallel to a longitudinal axis of the second beam so the first fabric pocket and the second fabric pocket are interposed by the first beam, the second beam, and the fabric covering the first beam and the second beam, and wherein each of the first fabric pocket and the second fabric pocket is peripherally enclosed along its longitudinal length to delineate a longitudinal cavity open on at least one longitudinal end.

2 . The occlusion device of claim 1 , wherein each of the first and second beams receives a portion of the first spring.

3 . The occlusion device of claim 1 , wherein the first and second fabric pockets are permanent.

4 . The occlusion device of claim 1 , wherein a length of the first fabric pocket is less than a length of the first beam.

5 . The occlusion device of claim 4 , wherein a length of the second fabric pocket is less than a length of the second beam.

6 . The occlusion device of claim 1 , wherein the first and second beams each comprise a load spreading platen.

7 . The occlusion device of claim 1 , further comprising a deployment device removably coupled to each of the first and second fabric pockets.

8 . The occlusion device of claim 7 , wherein the deployment device is configured to transition the left atrial appendage occlusion device from a closed position to an open position.

9 . The occlusion device of claim 7 , wherein the deployment device includes a first shaft configured to be removably received within the first fabric pocket, and a second shaft configured to be removably received within the second fabric pocket.

10 . A left atrial appendage occlusion device comprising:

a first beam and a second beam biased toward one another by a pair of U-shaped springs, wherein each of the first beam and the second beam comprises a permanent pocket extending parallel to a longitudinal axis of at least one of the first beam and the second beam, and wherein each permanent pocket includes an open, first longitudinal end and a closed, second longitudinal end peripherally bounded therebetween to delineate a longitudinal cavity configured to receive a repositionable shaft for repositioning the first beam with respect to the second beam.

11 . The occlusion device of claim 10 , wherein each of the first and second beams receives a portion of each of the pair of U-shaped springs.

12 . The occlusion device of claim 10 , wherein the pair of U-shaped springs are parallel to one another.

13 . The occlusion device of claim 10 , wherein a length of at least one of the permanent pockets is less than a length of the first beam.

14 . The occlusion device of claim 10 , wherein a length of each of the permanent pockets is less than a length of the first beam.

15 . The occlusion device of claim 10 , wherein each of the first beam and the second beam comprises a load spreading platen.

16 . The occlusion device of claim 10 , further comprising a deployment device removably coupled to each of the first beam and the second beam.

17 . The occlusion device of claim 16 , wherein the deployment device includes a pair of repositionable shafts configured to be received within the permanent pockets, wherein the pair of repositionable shafts are configured to move apart from one another to reposition the occlusion device from a closed position to an open position.

18 . A left atrial appendage occlusion device comprising:

a first beam and a second beam biased toward one another using a first spring, wherein the first beam and the second beam are covered by a fabric, and a first fabric pocket is sewn along its longitudinal length to the fabric covering the first beam, and a second fabric pocket is sewn along its longitudinal length to the fabric covering the second beam, wherein the first fabric pocket has a dominant longitudinal dimension extending parallel to a longitudinal axis of the first beam and the second fabric pocket has its own dominant longitudinal dimension extending parallel to a longitudinal axis of the second beam, and wherein a majority of the dominant longitudinal dimension of each of the first and second constituent pockets is peripherally enclosed to delineate a longitudinal cavity open at one longitudinal end.

19 . The occlusion device of claim 18 , wherein a length of the first fabric pocket is less than a length of the first beam, and a length of the second fabric pocket is less than a length of the second beam.

20 . The occlusion device of claim 18 , further comprising a deployment device removably coupled to each of the first beam and the second beam, wherein the deployment device includes a first shaft configured to be received within the first fabric pocket, and a second shaft configured to be received within the second fabric pocket, wherein the first shaft is repositionable with respect to the second shaft when the first and second shafts are received within the first and second fabric pockets in order to reposition the occlusion device from a closed position to an open position.
