Abstract

An opening in a fascia is closed by inserting a cannula through the fascia, and attaching a tissue anchor to the fascia from the exterior or through a side of the cannula.

Claims

1. An instrument for performing surgery, comprising:

a cannula having a distal end and a proximal end connected by a substantially cylindrical body, configured to be inserted through tissue into a body cavity, wherein the cannula includes at least one openable port in a wall of the cylindrical body.

2. The instrument of claim 1, wherein the instrument further comprises a cutting edge.

6. The instrument of claim 1, wherein the cannula includes at least two cylinders, and wherein the openable port is an opening in at least one of these cylinders.

9. The instrument of claim 6, wherein the openable port is openable by relatively rotating the at least two cylinders.

10. The instrument of claim 6, wherein the openable port is configured to be opened by withdrawing one of the at least two cylinders.

11. The instrument of claim 6, wherein the two cylinders are configured to lock together with the openable port open.

12. The instrument of claim 6, wherein the two cylinders are configured to lock together with the openable port closed.

13. The instrument of claim 1, wherein the openable port is configured to be opened by removing a block from an opening.

14. The instrument of claim 13, wherein the block is configured to be replaced in the opening to reseal the port.

16. The instrument of claim 1, wherein the openable port is configured to permit access to tissue when the cannula is inserted through tissue.

17. The instrument of claim 1, further comprising an anchor deployment mechanism, configured to place a tissue anchor in tissue outside the cannula and adjacent to the openable port.

18. The instrument of claim 17, wherein the anchor deployment mechanism is configured to be inserted into the cannula.

21. The instrument of claim 17, wherein the anchor deployment mechanism includes a mechanism for securing the tissue anchor to the tissue outside the cannula.

24. An instrument for performing surgery, comprising:

a cannula having a distal end and a proximal end connected by a substantially cylindrical body, configured to be inserted through tissue into a body cavity, wherein the cannula includes a structure configured for mounting a tissue anchor on the exterior of the substantially cylindrical body.

25. The instrument of claim 24, further comprising at least one tissue anchor mounted on the exterior of the substantially cylindrical body.

26. The instrument of claim 25, further comprising an anchor deployment mechanism, configured to place the tissue anchor in tissue outside the cannula.

31. The instrument of claim 25, wherein the tissue anchor is configured to engage an approximation mechanism.

32. The instrument of claim 24, further comprising an anchor deployment mechanism, configured to place a mounted tissue anchor in tissue outside the cannula.

33. The instrument of claim 24, wherein the structure configured for mounting a tissue anchor includes a recess shaped to accept a tissue anchor on the exterior of the cannula.

40. A method of performing surgery on a body, comprising:

inserting into the body a cannula having a distal end and a proximal end connected by a substantially cylindrical body, the cannula having at least one openable port in a wall of the cylindrical body, wherein inserting includes creating an opening in a fascia and passing the cannula through the opening;

accessing the body via the cannula with the openable port sealed;

opening the openable port;

applying a tissue anchor to the fascia through the opened openable port;

removing the cannula from the body; and

closing the opening via the tissue anchor.

41. The method of claim 40, wherein the cannula includes two concentric cylindrical members.

44. The method of claim 41, wherein opening the openable port includes locking the two concentric cylindrical members in an open position.

45. The method of claim 41, wherein opening the openable port includes unlocking the two concentric cylindrical members from a closed position.

46. The method of claim 40, wherein the cannula includes a transparent portion.

47. The method of claim 46, wherein the transparent portion is positioned to allow visualization of the fascia.

48. The method of claim 40, wherein accessing the body includes performing surgery in the body.

49. The method of claim 48, wherein the surgery is endoscopic.

50. The method of claim 48, wherein the surgery is laparoscopic.

55. A method of performing surgery on a body, comprising:

inserting into the body a cannula having a distal end and a proximal end connected by a substantially cylindrical body, the cannula having at least one tissue anchor mounted on its exterior, wherein inserting includes creating an opening in a fascia and passing the cannula through the opening;

accessing the body via the cannula;

applying the tissue anchor to the fascia;

removing the cannula from the body; and

closing the opening via the tissue anchor.

56. The method of claim 55, wherein the cannula includes a tissue anchor deployment mechanism, and wherein applying the tissue anchor to the fascia includes activating the tissue anchor deployment mechanism.

62. The method of claim 55, wherein the tissue anchor is mounted in a recess on the exterior of the cannula.

65. The method of claim 55, wherein accessing the body includes performing surgery in the body.

70. A method of closing an opening in a fascia, comprising:

inserting though the opening a cannula having a distal end and a proximal end connected by a substantially cylindrical body, the cannula having at least one openable port in a wall of the cylindrical body;

applying a tissue anchor to the fascia through the opened openable port;

removing the cannula from the body; and

closing the opening via the tissue anchor.

76. The method of claim 70, wherein the cannula includes a transparent portion.

78. The method of claim 70, wherein accessing the body includes performing surgery in the body.

81. The method of claim 70, wherein the tissue anchor is configured to pierce the fascia.

82. The method of claim 70, wherein the tissue anchor is configured to grasp the fascia.
