Abstract

Devices and methods for managing access through tissue is disclosed. The device includes a body. The body is movable from a pre-deployed configuration towards a deployed configuration. The device includes a plurality of tissue engaging portions that extend from the body. At least a portion of the tissue engaging portions are obtuse. 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. The first distance is smaller than the second distance. The method includes deploying a closure element to tissue adjacent a tissue opening to substantially close the opening following a first procedure. The method also includes selectively opening the opening in the tissue by advancing a distal end of a medical device through the deployed closure element as a part of or before a second procedure.

Claims

1. A method for managing access through tissue, comprising:

deploying a closure element, having a plurality of tissue engaging portions, to tissue adjacent a tissue opening to bring the plurality of tissue engaging portions of the closure element toward one another to bring tissue together to substantially close the opening following a first procedure; and

following closing of the tissue opening and following the first procedure and removal of any devices used during the first procedure and removal of a delivery device for deploying the closure element, advancing a distal end of a medical device through the deployed closure element as a part of or before a second procedure to selectively open the tissue opening and transition the deployed closure element from a deployed configuration towards a pre-deployed configuration and move the plurality of tissue engaging portions away from each other.

2. The method as in claim 1, wherein the tissue is skin.

3. The method as in claim 1, wherein the tissue is a wall of a body lumen.

4. The method as in claim 1, further comprising:

removing the distal end of the medical device through the opening in the tissue and through the closure element thereby redeploying the closure element to the tissue adjacent the opening in the tissue to substantially close the opening.

5. The method as in claim 1, wherein the closure element further comprises a radiopaque marker and wherein the method further comprises locating the deployed closure element using the radiopaque marker.

6. The method as in claim 1, wherein the method further comprises locating the deployed closure element using skin marking.

7. The method as in claim 1, wherein the medical device includes a cannula or other access device.

8. The method as in claim 1, wherein the closure element further comprises:

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

the plurality of tissue engaging portions extending from the body, at least a portion of the tissue engaging portions being obtuse, 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.

9. A method for managing access to a body lumen, comprising:

deploying a closure element to tissue adjacent a tissue opening to substantially close the opening following a first procedure with a plurality of non-penetrating tissue engaging portions, the closure element comprising;

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

the plurality of non-penetrating tissue engaging portions extending from the body, at least a portion of the non-penetrating tissue engaging portions being obtuse, at least two of the non-penetrating 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

wherein deploying the closure element brings the plurality of non-penetrating tissue engaging portions of the closure element towards one another to bring tissue together to substantially close the opening following the first procedure;

following closing of the tissue opening and following the first procedure and removal of any devices used during the first procedure and removal of a delivery device for deploying the closure element, locating the deployed closure element at the closed tissue opening;

following locating the deployed closure element, selectively opening the opening in the tissue by advancing a distal end of a medical device through the deployed closure element as a part of or before a second procedure to selectively open the tissue opening and transition the deployed closure element from a deployed configuration towards a pre-deployed configuration and move the plurality of tissue engaging portions away from each other; and

removing the distal end of the medical device through the opening in the tissue and through the closure element thereby redeploying the closure element to the tissue adjacent the opening in the tissue to substantially close the opening.

10. The method as in claim 9, wherein the tissue is skin.

11. The method as in claim 9, wherein the tissue is a wall of a body lumen.

12. The method as in claim 9, wherein the closure element further comprises a radiopaque marker and wherein the method further comprises locating the deployed closure element using the radiopaque marker.

13. The method as in claim 9, wherein the locating the deployed closure element further comprises locating the deployed closure element using skin marking.

14. The method as in claim 9, wherein the medical device includes a cannula or other access device.
