METHODS AND DEVICES TO TREAT DISEASED OR INJURED MUSCULOSKELETAL TISSUE
First Claim
1. A knotless suture anchoring system comprising:
- an outer anchor having a central channel and a distal tip adapted to penetrate tissue;
an inner anchor positionable in the central channel of the outer anchor;
a locking feature on one or both of the inner and outer anchors configured to retain the inner anchor within the central channel; and
a continuous length of suture coupled with the inner and outer anchors, the suture having a free end,wherein at least one of the inner and outer anchors further comprises a cinching mechanism adapted to allow the suture to be tensioned by passage of the suture through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained.

Abstract
A knotless suture anchoring system includes an outer anchor having a central channel and a distal tip adapted to penetrate tissue. An inner anchor is positionable in the central channel of the outer anchor and a locking feature on one or both of the inner and outer anchors retains the inner anchor within the central channel. A continuous length of suture is coupled with the inner and outer suture anchors and has a free end. At least one of the inner and the outer anchors also has a cinching mechanism that allows the suture to be tensioned by passage of the suture through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained.

11. A knotless suture anchoring system comprising:
-
an outer anchor having a central channel and a distal tip adapted to penetrate tissue; an inner anchor positionable in the central channel of the outer anchor and having a distal tip adapted to penetrate and be retained in tissue outside the outer anchor whereby the inner anchor may be positioned either in the outer anchor or in tissue apart from the outer anchor; a locking feature on one or both of the inner and outer anchors configured to retain the inner anchor within the central channel; and a continuous length of suture coupled with the inner and outer anchors, the suture having a free end, wherein at least one of the inner and outer anchors further comprises a clamping mechanism adapted to clamp the suture under tension without knotting the suture. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A knotless suture anchoring system comprising:
-
a first anchor having a housing with a central channel sized to receive a suture therein; and a cinching mechanism having a radially deflectable arm integral with the housing and disposed at least partially in the central channel, the suture passing through an opening in the arm and passing between a free end of the arm and the housing, wherein the cinching mechanism is adapted to allow the suture to pass through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A knotless suture anchoring system comprising:
-
a pin having a distal tip adapted to penetrate tissue; an anchoring bracket; and a length of suture, wherein the suture is adapted to be coupled to the pin and the bracket. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56)

57. A knotless suture anchoring system comprising:
-
a delivery instrument having a longitudinal axis, a shaft axially movable along the longitudinal axis, and a hammer adapted to convert axial movement along the longitudinal axis into movement transverse thereto; and a first anchor carried by the delivery instrument and having a distal tip adapted to penetrate tissue, wherein axial movement of the slidable shaft along the longitudinal axis moves the hammer in a motion transverse thereto, thereby impacting the anchor, whereby the first anchor is driven into the tissue at an angle transverse to the longitudinal axis of the delivery instrument.

58. A method of knotless suturing comprising:
-
providing a delivery instrument carrying a first anchor and a second anchor, wherein a continuous length of suture is coupled with the first and the second anchors; advancing the delivery instrument to a treatment region comprising treatment tissue; placing the first anchor into a first region of the tissue; coupling the suture to a portion of the treatment tissue; attaching the second anchor to the first anchor; tensioning the suture; and securing the suture without knotting the suture by moving the suture through a cinching mechanism in the first or the second anchor, wherein the cinching mechanism is adapted to allow the suture to move through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained independently of the position of the second anchor relative to the first anchor. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)

71. A method of knotless suturing comprising:
-
providing an anchoring device having an anchoring bracket, a length of suture and a pin, wherein the suture is coupled to the bracket and the pin; anchoring the bracket to a first tissue region; capturing tissue to be treated with the suture; securing the pin to a structure selected from the bracket and a second tissue region; and tensioning the suture. - View Dependent Claims (72, 73, 74, 75)
