Abstract

Devices and methods are disclosed herein for a closure device. A closure device includes a body movable from a pre-deployed configuration towards a deployed configuration, a plurality of tissue-engaging portions extending from the body. At least two of the tissue-engaging portions are separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration in which the first distance is smaller than the second distance. The closure device also includes a plurality of device-capture features secured to the body. The device-capture features are configured to move the tissue-engaging portions to a separation greater than the first distance.

Claims

1. A closure device, comprising:

a body movable from a pre-deployed configuration towards a deployed configuration;

a plurality of tissue-engaging portions extending from the body, at least two of the tissue-engaging portions being separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration, wherein the first distance is smaller than the second distance; and

a plurality of device-capture features secured to the body, the device-capture features being configured to move the tissue-engaging portions to a separation greater than the first distance.

2. The device of claim 1, the body further defining a plane, the body being disposed about a central axis extending substantially normal to the plane in the deployed configuration, the body being disposed out of the plane in the pre-deployed configuration, the tissue-engaging portions being oriented generally towards the central axis in the deployed configuration, and generally parallel to the central axis in the pre-deployed configuration.

3. The device of claim 1, wherein the body is biased towards the deployed configuration for biasing at least one of the tissue-engaging portions towards another tissue-engaging portion and the device capture feature is configured to move at least one of the tissue-engaging portions away from another tissue-engaging portion.

4. The device of claim 1, wherein the body comprises an inner periphery and an outer periphery and wherein at least one of the device-capture features is disposed within the inner periphery.

5. The device of claim 1, wherein the body comprises an inner periphery and an outer periphery and wherein at least one of the device-capture features is disposed generally about the outer periphery.

6. The device of claim 1, wherein the body comprises an inner periphery and an outer periphery and wherein at least one of the device-capture features is disposed outside of the outer periphery.

7. The device of claim 1, wherein the body comprises an inner periphery and an outer periphery and wherein at least one of the device-capture features is disposed inside of the outer periphery.

8. The device of claim 1, wherein the body comprises an inner periphery and an outer periphery and wherein at least one of the device-capture features is disposed outside of the inner periphery.

9. The device of claim 1, wherein at least one of the device-capture features includes a marker for visualizing the device-capture features.

10. The device of claim 9, wherein adjacent tissue-engaging portions have a first curved region disposed between them.

11. The device of claim 1, wherein the plurality of tissue-engaging elements further comprises:

a first primary tissue-engaging portion having a first length; and

a second primary tissue-engaging portion having a second length, the first and second primary tissue-engaging portions being disposed on opposing first curved regions and oriented towards one another in the deployed configuration, the first and second lengths causing the first and second primary tissue-engaging portions to at least partially overlap one another in the deployed configuration.

12. A method, comprising:

deploying a closure element having tissue-engaging portions and device-capture features, the tissue-engaging portions engaging tissue adjacent a tissue opening to substantially close the opening;

engaging device-capture features with a distal end of a medical device; and

moving the device-capture features to withdraw the tissue-engaging portions from engagement with the tissue adjacent the tissue opening.

13. The method as in claim 12, wherein the tissue is skin.

14. The method as in claim 12, wherein the tissue is a wall of a body lumen.

15. The method as in claim 12, further comprising removing the closure element.

16. The method as in claim 12, wherein the closure element further comprises a radiopaque marker and wherein the method further comprises locating the deployed closure element using the radiopaque marker.

17. The method as in claim 12, wherein moving the device-capture features to withdraw the tissue-engaging portions includes moving the device-capture features in a direction away from a central axis of the closure element.

18. The method as in claim 12, wherein moving the device-capture features to with the tissue-engaging portions includes moving the tissue-engaging portions toward a direction being generally parallel to a central axis of the closure element.

19. A method, comprising:

deploying a closure element to tissue adjacent a tissue opening to substantially close the opening following a first procedure, the closure element including a body having a plurality of expandable elements, the expandable elements being configured to move resiliently between a pre-deployed configuration and a deployed configuration, a plurality of tissue-engaging portions extending from the body, at least two of the tissue-engaging portions being separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration, wherein the first distance is smaller than the second distance, and a plurality of device capture elements operatively associated with the expandable elements;

locating the deployed closure element;

engaging the device-capture features; and

moving the device-capture features to withdraw the tissue-engaging portions from engagement with the tissue adjacent the tissue opening.

20. The method as in claim 19, wherein the tissue is skin.

21. The method as in claim 19, wherein the expandable elements include alternating curved elements having inner and outer curved regions.

22. The method as in claim 21, wherein moving the device-capture features to withdraw the tissue-engaging portions includes applying a force to at least one of the inner curved regions.

23. The method as in claim 21, wherein moving the device-capture features to withdraw the tissue-engaging portions includes applying a force to at least one of the outer curved regions.
