Abstract

A tissue connector has a first pointed end, an anchor end, a body with a periphery and a plurality of protrusions projecting from said periphery of said body. The plurality of protrusions are adapted to grasp tissue in a direction of movement of the first end of the connector through tissue and are not adapted to grasp tissue in an opposite direction of movement of the connector through tissue, which is in the direction of the anchor end. At axial locations of said body, three said protrusions are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body protrusions are locate at about 120 degree spacings.

Claims

1. A tissue connector comprising:

an elongated body with a circular cross-sectional shape having a first end, a second end, a circular periphery, and a plurality of protrusions extending from said circular periphery of the body,

wherein said protrusions extend along a portion of said body and face the first end, the protrusions are adapted to grasp tissue in a direction of movement of the first end of the connector through tissue and are not adapted to grasp tissue in an opposite direction of movement of the connector through tissue;

wherein at each of a plurality of axial locations of said body, said protrusions face said first end and are about equally and circumferentially spaced about the circular periphery of the body, and

said first end including a pointed end, and said second end including a head.

2. The tissue connector of claim 1 wherein:

said head includes an anchor which is adapted to prevent tissue from going past said head.

3. The tissue connector of claim 1 wherein:

said head is larger than a diameter of said elongated body and said head is adapted to prevent tissue from going past said head.

4. The tissue connector of claim 1 wherein:

said head is adapted to have tissue located below said head.

5. The tissue connector of claim 1 wherein:

said head is adapted to be located above tissue.

6. The tissue connector of claim 1 and including:

a cannula through which said tissue connector is adapted to be deployed into tissue.

7. The tissue connector of claim 1 and including:

a cannula through which said tissue connector is adapted to be deployed into tissue during an endoscopic procedure.

8. The tissue connector of claim 1 wherein:

said protrusions are arranged on said periphery and adapted to lessen a tendency of said connector to damage tissue.

9. The tissue connector of claim 1 wherein:

said protrusions are conical.

10. The tissue connector of claim 1 wherein:

said connector is made of a bioabsorbable material.

11. The tissue connector of claim 1 wherein:

said protrusions are arranged in a helical pattern.

12. The tissue connector of claim 1 wherein:

said protrusions have a non-uniform configuration.

13. The tissue connector of claim 1 wherein:

said protrusions are located in staggered positions about said periphery of said connector.

14. The tissue connector of claim 1 wherein:

said pointed end is free of protrusions.

15. The tissue connector of claim 1 wherein said protrusions are barbs.

16. The tissue connector of claim 1 wherein said protrusions are tissue holding elements.

17. The tissue connector of claim 1 wherein at said axial locations of the plurality of axial locations, three said protrusions are about equally and circumferentially spaced about the circular periphery of the body.

18. A tissue connector comprising:

an elongated body with a circular cross-sectional shape having a first end, a second end, a circular periphery, and a plurality of protrusions extending from said circular periphery of the body,

wherein said protrusions extend along a portion of said body and faces said first end, the protrusions are adapted to grasp tissue in a direction of movement of the first end of the connection through tissue and are not adapted to grasp tissue in an opposite direction of movement of the connection through tissue; and

wherein at each of a plurality of axial locations of said body, said protrusions face said first end and are about equally and circumferentially spaced about the circular periphery of the body, and

said first end including a pointed end, and said second end including a head; and

said head is larger than a diameter of said elongated body and said head is adapted to prevent tissue from going past said head such that said head is adapted to be located adjacent to tissue.

19. The tissue connector of claim 18 wherein:

said head includes an anchor.

20. The tissue connector of claim 18 wherein at said axial locations of the plurality of axial locations, three said protrusions are about equally and circumferentially spaced about the circular periphery of the body.
