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

1. A tissue attachment device, comprising:

a frame with a first major surface, a second major surface opposite the first major surface, a peripheral surface that extends between the first and second major surfaces, and a surface between the first and second major surfaces and opposite the peripheral surface defining a pinch point region configured to engage a biological tissue, the pinch point region having a predefined opening defined by a predefined shape, where the frame elastically deforms under a stress to alter an area of the predefined opening and the predefined shape of the pinch point region to close an opening in the biological tissue; and

a tab integrally formed from the frame and positioned radially from a center of the pinch point region, where the tab is defined by an opening having an arcuate shape between the first major surface and the second major surface of the frame and an open anchor attachment defined by another opening between the first major surface and the second major surface of the frame such that the frame surrounds the tab, where when the frame is in an elastically undeformed state the tab extends in an upright position relative the first major surface of the frame and the tab is adapted to receive a suture through the open anchor attachment of the tab to provide an anchor attachment for the frame.

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 the upright position from a position planar with the frame.

9. The device of claim 8, where the tab folds into an upright position relative the second major surface of the frame.

10. The device of claim 9, where a vacuum is applied through a 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.
