Abstract

An engaging element for engaging tissue is described. The engaging element may include a first member including at least one tissue engaging portion and a second member including at least one tissue engaging portion. The second member may be pivotally connected to the first member. The engaging element includes a locking mechanism operatively associated with the first and second member. The locking mechanism may be configured to inhibit the relative motion of the first and said second member. An engaging system for engaging tissue is described. The engaging system may include an engaging element for engaging tissue, a first member having at least one tissue engaging portion, and/or a second member including at least one tissue engaging portion. A method for engaging tissue is described. The method may include positioning an engaging element relative to an engaging element delivery device and/or to a portion of tissue.

Claims

1. An engaging system for engaging tissue, the engaging system comprising:

an engaging element for engaging tissue, said engaging element comprising;

a first member including at least one tissue engaging portion having a sharpened tip, said sharpened tip extending distally from said first member;

a second member including at least one tissue engaging portion and being pivotally connected to said first member;

an elongate aligning portion located on at least one of the first member and the second member, the elongate aligning portion extending along a length and transversely from a surface of at least one of the first member and the second member;

a pivoting mechanism operatively associated with said first and said second member wherein said pivoting mechanism comprises a pivoting opening located on one of said first member and said second member and a pivoting member located on the other of said first member and said second member, and said pivoting member engaging the pivoting opening;

a locking mechanism operatively associated with said first member and said second member, said locking mechanism being configured to inhibit relative motion between said first member and said second member; and

a retaining member, said retaining member comprising a retaining mechanism configured to limit motion of the engaging element both longitudinally through the retaining member and radially about an axis within the retaining member, said retaining member further comprising an aligning mechanism which is operatively associated with said elongate aligning portion, said aligning mechanism being complementary to said elongate aligning portion to receive said elongate aligning portion; and

an engaging element delivery device, said engaging element delivery device comprising a transitioning member, said transitioning member being configured to transition said engaging element from an open configuration toward a closed configuration,

wherein said retaining mechanism is engaged with said pivoting opening to selectably inhibit relative motion between said engaging element and said retaining member.

2. The engaging system of claim 1, wherein said first member and said second member further comprise a proximal end, said proximal end of said first member and said proximal end of said second member being separated by a first transitioning dimension in said open configuration and being separated by a second transitioning dimension in said closed configuration.

3. The engaging system of claim 2, wherein said first transitioning dimension is larger than said second transitioning dimension.

4. The engaging system of claim 2, wherein said first transitioning dimension is smaller than said second transitioning dimension.

5. The engaging system of claim 1, wherein said locking mechanism comprises a first locking portion and a second locking portion, relative movement of said at least one tissue engaging portion of said first member and said at least one tissue engaging portion of said second member being inhibited by operative association between said first locking portion and said second locking portion.

6. The engaging system of claim 5, wherein said first locking portion comprises at least one tooth located on said first member and said second locking portion comprising a locking member located on said second member.

7. The engaging system of claim 6, wherein said locking member and said at least one tooth inhibit said at least one tissue engaging portion of said first member and said at least one tissue engaging portion of said second member from opening.

8. The engaging system of claim 6, wherein said locking member is biased toward said at least one tooth.

9. The engaging system of claim 5, wherein said first locking portion comprises a latch located on said first member and said second locking portion comprising a latching portion located on said second member.

10. The engaging system of claim 9, wherein said latch and said latching portion inhibit said at least one tissue engaging portion of said first member and said at least one tissue engaging portion of said second member from opening.

11. The engaging system of claim 1, wherein said at least one tissue engaging portion of said first member and said at least one tissue engaging portion of said second member are separated by a first distal dimension in said open configuration and are separated by a second distal dimension in said closed configuration, said first distal dimension being larger than said second distal dimension.

12. The engaging system of claim 1, wherein said engaging element comprises bioabsorbable, biodegradable, and/or bioerodible material.

13. The engaging system of claim 12, wherein said engaging element further comprises collagen, polycaprolactone (PCL), poly-D,L-lactic acid, Poly-L-lactic acid, poly (lactide-co-glycolide), poly(hydroxybutyrate), polyanhydrides, and/or poly(glycolic acid).

14. The engaging system of claim 1, wherein said retaining mechanism further comprises a retaining detent that engages said pivoting opening to selectably inhibit the relative motion between said engaging element and said retaining member.

15. The engaging system of claim 1, wherein said retaining member and said transitioning member are axially aligned.

16. The engaging system of claim 1, wherein said retaining member is configured to slidably receive said transitioning member.

17. The engaging system of claim 1, wherein said first member and said second member of said engaging element further comprise a transitioning portion, said transitioning member comprising a transitioning surface, said transitioning surface being shaped to engage with said transitioning portion of at least one of said first member and said second member of said engaging element.

18. The engaging system of claim 17, wherein said transitioning surface has a convex shape.

19. The engaging system of claim 17, wherein said transitioning surface has a concave shape.
