Abstract

The present disclosure relates generally to devices, systems, and methods for use with tissue, more particularly the present disclosure relates to a device including a frame with a surface defining a pinch point region with a predefined shape. The device also includes a tab with an opening defining an anchor attachment on the frame. The frame can elastically deform under a stress to alter the predefined shape of the pinch point region.

Claims

13. A device, comprising:

a frame with a surface defining an array of pinch point regions having a predefined shape; and

a member coupled to the frame, where the frame elastically deforms under a stress applied through the member to alter the predefined shape of the pinch point regions.

14. The device of claim 13, where the stress is applied through the member in a planar direction to deform the pinch point regions.

15. The device of claim 13, where the stress is applied through the member to deform the frame to a configuration where the predefined shape of the pinch point regions deform into a projection.

16. The device of claim 13, where the stress is applied through the member to deform the frame into an arcuate shape, where the predefined shape of the pinch point regions deform into a projection.

17. The device of claim 13, where the member is detachable from the frame.

18. The device of claim 13, where the frame is formed from a material having a transition temperature, where heating the material above the transition temperature causes the array of pinch point regions to return towards the predefined shape.

19. The device of claim 13, where the surface of the frame further defines an array of projections.

20. The device of claim 13, including a delivery device, the delivery device comprising:

an elongate body member having a first arm and a second arm connected by a pivot point; and

a series of hooks on distal ends of the first and second arm, where the series of hooks releasably engage the frame, and where the first and second arms move to apply the stress to the member to elastically deform the frame.

21. The device of claim 20, where the distal ends of the first and second arms move apart as proximal ends of the first and second arm are moved towards each other.

22. The device of claim 20, including an elongate tubular body positioned on top of the first or second arm and a vacuum is applied through the elongate tubular body to provide a vacuum force at the distal end of the first or second arm.

23. A device, comprising:

a frame with a first region, a second region, and an elastic region, the first region and the second region each including a surface defining a projection, where the elastic region applies a force on the first and second region when the frame is deformed, and the projection extends in the direction of the force.

1. A device, comprising:

a frame with a surface defining a pinch point region having a predefined shape; and

a tab provided with the frame, the tab having an opening defining an anchor attachment on the frame, where the frame elastically deforms under a stress to alter the predefined shape of the pinch point region.

2. The device of claim 1, where the surface defines a corner of the pinch point region that projects from a planar configuration of the frame as the frame elastically deforms.

3. The device of claim 2, where the corner of the pinch point region and the frame elastically return toward the planar configuration when the stress to the frame is removed.

4. The device of claim 1, where a portion of the surface projects from a planar configuration of the frame as the frame elastically deforms.

5. The device of claim 4, where a portion of the surface and the frame elastically return toward the planar configuration when the stress to the frame is removed.

6. The device of claim 4, where the surface defining the pinch point region defines a pinch point region having a circular configuration.

7. The device of claim 1, where the frame is coupled to an electrical contact to form an electrode.

8. The device of claim 1, where the tab folds to an upright position from a position planar with the frame.

9. The device of claim 8, where the tab folds into an upright position that is non-planar to the frame.

10. The device of claim 9, where a vacuum is applied through the third elongate inner tubular body to provide a vacuum force at a distal end of the third elongate inner tubular body.

11. The device of claim 1, including a catheter, the catheter including:

a first elongate exterior tubular body;

a second elongate tubular body having a proximal end and a distal end, the second elongate tubular body positioned within the first elongate tubular body; and

a third elongate inner tubular body positioned at least partially within the second elongate tubular body, where the frame abuts the distal end of the second elongate tubular body and is held in a deformed configuration between the third elongate inner tubular body and the first elongate exterior tubular body.

12. The device of claim 11, where the first elongate exterior tubular body and the second elongate tubular body can move longitudinally relative each other, and the distal end of the second elongate tubular body holds the frame as the first elongate exterior tubular body is retracted to allow the frame to return toward a planar configuration.

24. The device of claim 23, where the surface defining a projection includes an array of projections.

25. The device of claim 23, where the frame has a cylindrical configuration.

26. The device of claim 23, where the frame has a circular configuration.

27. The device of claim 26, where the frame deforms radially.

28. The device of claim 23, where the frame is deformed by expanding the elastic region.

29. The device of claim 28, where the tab folds to an upright position from a position planar with the frame.

27-1. The device of claim 23, where the frame is deformed by contracting the elastic region.

28-2. The device of claim 23, further comprising a tab provided with the frame, the tab having an opening defining an anchor attachment on the frame.

30. A method comprising:

applying a stress to a frame to expand a pinch point region defined by the frame;

applying the expanded pinch point regions to a material; and

releasing the stress to the frame to allow the pinch point regions to contract on the material.

31. The method of claim 30, where applying the stress to the frame includes applying the stress in a planar direction.

32. The method of claim 30, where applying the stress to the frame includes holding the frame in a deformed configuration between an outer and an inner elongate tubular body of a delivery catheter.

33. The method of claim 32, where releasing the stress includes retracting the outer elongate tubular body of the delivery catheter.

34. The method of claim 30, where applying the expanded pinch point regions to the material includes applying a vacuum force to assist in the application of the expanded pinch point regions to the material.
