Abstract

A medical device that includes a plurality of members forming a body that can transition from a delivery configuration to a deployed configuration. The plurality of members form a plurality of openings each with a long axis extending substantially longitudinally relative to a longitudinal axis of the medical device in a delivery configuration. A plurality of end portions are associated with a distal portion of the medical device, the end portions extending towards the longitudinal axis in a deployed configuration.

Claims

1. A medical device comprising:

a plurality of members forming a body, the body being configured to transition from a delivery configuration to a deployed configuration, the plurality of members forming a plurality of openings each with a long axis extending substantially longitudinally relative to a longitudinal axis of the medical device in the delivery configuration, wherein each opening has a mid-portion having a width in a direction transverse to the long axis of the opening greater than widths of a remainder of the opening in the deployed configuration; and

a plurality of end portions disposed at a distal portion of the medical device, each end portion extending towards the longitudinal axis in the deployed configuration.

2. The medical device of claim 1, wherein each end portion extends away from the opening to engage tissue disposed adjacent to the tissue engaging portion.

3. The medical device of claim 1, wherein the plurality of end portions are disposed substantially symmetrically about the longitudinal axis.

4. The medical device of claim 1, wherein the openings are biased toward an expanded, deployed configuration.

5. The medical device of claim 1, wherein the plurality of members comprises a first member adjacent to a second member, the first member and the second member being coupled together at a hinged region.

6. The medical device of claim 1, wherein the plurality of end portions extend distally from a proximal end of the plurality of openings.

7. The medical device of claim 1, wherein the body is formed of a shape memory material.

8. A method comprising:

locating an opening in tissue; and

following locating the opening, deploying a medical device near the opening so that a portion of the medical device engages tissue, the medical device comprising;

a plurality of members forming a body, the body being configured to transition from a delivery configuration to a deployed configuration, the plurality of members forming a plurality of openings with a long axis extending substantially longitudinally relative to a longitudinal axis of the medical device in the delivery configuration, wherein each opening has a mid-portion having a width in a direction transverse to the long axis of the opening greater than widths of a remainder of the opening in the deployed configuration; and

a plurality of end portions disposed at a distal portion of the medical device, each end portion extending towards the longitudinal axis in the deployed configuration.

9. The method of claim 8, wherein deploying the medical device further comprises advancing the medical device along an elongate member until the medical device disengages from the elongate member.

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

11. The method of claim 8, wherein deploying the medical device further comprises advancing the medical device to move the plurality of end portions with the plurality of members, the plurality of members forming a plurality of spring elements.

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

13. The method of claim 8, further comprising monitoring a position of the medical device.

14. The method of claim 13, wherein monitoring the position of the medical device comprising monitoring one or more radiopaque markers using fluoroscopy.

15. The method of claim 14, further comprising monitoring a relative position of the medical device to a distal tip of a locator locating the opening in tissue.
