Abstract

A medical device that 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. A plurality of tissue engaging portions are associated with the plurality of struts, with each tissue engaging portion extending towards the longitudinal axis in a deployed configuration.

Claims

1. A 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 the medical device; and

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

2. The medical device of claim 1, wherein each generally diamond-shaped opening has a mid-portion having a width in a direction transverse to a longitudinal axis of the generally diamond-shaped opening greater than widths of a remainder of the generally diamond-shaped opening.

3. The medical device of claim 1, wherein each tissue engaging portion extends away from the generally diamond-shaped opening to engage tissue disposed adjacent to the tissue engaging portion.

4. The medical device of claim 1, wherein the plurality of tissue engaging portions are disposed substantially symmetrically about the longitudinal axis.

5. The medical device of claim 1, wherein the generally diamond-shaped openings are biased toward an expanded, deployed configuration.

6. The medical device of claim 1, wherein two adjacent struts of the plurality of struts are coupled together at a hinged region.

7. The medical device of claim 1, wherein the medical device includes 5 or more diamond-shaped openings.

8. The medical device of claim 1, wherein the plurality of tissue engaging portions extend distally from a proximal end of the plurality of generally diamond-shaped openings.

9. A medical device comprising:

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

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

10. The medical device of claim 9, wherein each generally diamond-shaped opening is configured to receive tissue.

11. The medical device of claim 9, wherein the plurality of curved elements are formed of a shape memory material.

12. The medical device of claim 9, wherein the plurality of curved elements collectively forms a plurality of spring elements configured to move the plurality of tissue penetrating portions.

13. The medical device of claim 9, wherein each apex is a tissue engaging portion.

14. The medical device of claim 13, wherein the apices being spaced substantially symmetrically about an axis of the medical device.

15. The medical device of 13, wherein each apex is a hinged region.
