Abstract

A method that includes locating an opening in tissue by advancing a member through the opening in tissue and following locating the opening, deploying a medical device to aid with sealing the opening. The medical device includes a plurality of strut members forming a plurality of generally diamond-shaped openings, the plurality of strut member being configured to form an annular shaped structure with the generally diamond-shaped openings extending generally longitudinally relative to a longitudinal axis of the medical device. The medical device further includes a plurality of tissue engaging portions associated with the plurality of struts, each tissue engaging portion being disposed between adjacently positioned generally diamond-shaped openings.

Claims

1. A method comprising:

locating an opening in tissue by advancing a member through an opening in tissue; and

following locating the opening, deploying a medical device to aid with sealing the opening, including releasing engagement between the member and the medical device so that a portion of the medical device engages tissue and closes the opening, the medical device comprising;

a plurality of strut members generally biased to a deployed configuration to form a plurality of generally diamond-shaped openings in an annular shaped structure with the generally diamond-shaped openings extending generally longitudinally relative to a longitudinal axis of medical device; and

a plurality of tissue engaging portions, each tissue engaging portion being disposed between adjacently positioned generally diamond-shaped openings.

2. The method of claim 1, wherein deploying the medical device further comprises releasing the medical device from the member.

3. The method of claim 1, wherein deploying the medical device comprises proximally moving the member to allow the medical device to expand.

4. The method of claim 1, wherein deploying the medical device further comprises advancing the medical device along the member until the medical device disengages from the member.

5. The method of claim 1, further comprising removing the member from the opening in tissue.

6. The method of claim 1, wherein deploying the medical device further comprises advancing the medical device to move the plurality of tissue engaging portions with the plurality of struts, the plurality of struts forming a plurality of spring elements.

7. The method of claim 1, wherein the plurality of struts are biased to position the plurality of tissue engaging portions for tissue engagement.

8. The method of claim 1, wherein locating the tissue further comprises positioning a locator through the opening in tissue.

9. A method comprising:

locating an opening in tissue by advancing a member through the opening in tissue; and

following locating the opening, deploying a medical device to penetrate tissue, including releasing engagement between the member and the medical device so that a portion of the medical device engages tissue and closes the opening, the medical device comprising;

a plurality of generally diamond-shaped openings formed from a plurality of looped elements generally biased to a deployed configuration to, the plurality of looped elements being configured to position the plurality of generally diamond-shaped openings in an annular arrangement; and

a plurality of tissue engaging portions, each tissue engaging portion being disposed between adjacently positioned generally diamond-shaped openings and extending from a junction of adjacent looped elements of the plurality of looped elements at a location spaced apart from an apex of the generally diamond-shaped openings.

10. The method of claim 9, further comprising monitoring a position of the medical device.

11. The method of claim 10, wherein monitoring the position of the medical device comprising monitoring one or more radiopaque markers using fluoroscopy.

12. The method of claim 11, further comprising monitoring a relative position of the medical device to a distal tip of a locator locating the opening in tissue.

13. The method of claim 9, wherein deploying the medical device further comprises releasing the medical device from the member.

14. The method of claim 9, wherein deploying the medical device further comprises advancing the medical device along the member until the medical device disengages from the member.

15. The method of claim 9, further comprising removing the member from the opening in tissue.

16. The method of claim 9, the medical device further comprising a plurality of strut members, wherein deploying the medical device further comprises advancing the medical device to move the plurality of tissue engaging portions with the plurality of struts, the plurality of struts forming a plurality of spring elements.

17. The method of claim 9, the medical device further comprising a plurality of strut members, wherein the plurality of struts are biased to position the plurality of tissue engaging portions for tissue engagement.

18. The method of claim 9, wherein locating the tissue further comprises positioning a locator through the opening in tissue.
