Suture retaining arrangement
DCFirst Claim
1. A device for attaching an object such as a suture to a bone, comprising:
- a relatively rigid, elongate body having first and second ends, a central portion between said ends, and a longitudinal axis extending through said ends; and
means for attaching a suture substantially midway between the first and second ends of the body at a point which is offset from the longitudinal axis so that, when the device is placed in a hole in the bone and a force having a component acting in a direction which is parallel to the longitudinal axis of the device is applied to the suture, the device will rotate causing the ends to engage the bone and prevent removal of the device and suture from the hole;
wherein at least one of said first and second ends is formed as a sharp point and wherein said sharp point is offset from the longitudinal axis, and faces away from said axis and the central portion of the elongate body.

Abstract
An arrangement for attaching a suture to a bone includes a device which has an elongate body having first and second ends, a central portion, and a longitudinal axis extending through the ends. A suture is attached to the central portion of the body at a point which is offset from the longitudinal axis so that, when the device is placed in a hole in the bone and a force having a component acting in a direction which is parallel to the longitudinal axis of the device is applied to the suture, the device will rotate causing the ends to engage the bone and prevent removal of the device and suture from the hole. The ends of the device are preferably formed as sharp points. One embodiment is formed from a continuous length of stainless steel rod which is bent into a 360° loop. A novel method of using the device to secure a suture to a bone includes forming a hole which extends through a cortical layer of the bone and into a cancellous portion of the bone to a depth which at least equals the length of the device. The device and attached suture are inserted into the hole such that the outwardly facing end of the device is disposed inwardly of the inner cortical wall of the bone. Pulling the suture causes the device to rotate such that the ends penetrate the relatively soft cancellous portion of the bone and come to rest substantially adjacent the inner wall of the relatively hard cortical bone so as to secure the suture in place.

15. A device for anchoring a suture to a bone or similar structure, comprising:
-
an elongate body having first and second ends, a central portion between said ends, a longitudinal axis extending through each of said ends, and a transverse axis extending through the central portion of the body and intersecting the longitudinal axis at substantially right angles; and means for attaching the suture substantially midway between the first and second ends of the body at a point along the transverse axis which is offset from the longitudinal axis; wherein said first end is formed as a point which is offset from the longitudinal axis in generally opposing relation to the means for attaching the suture. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A device for anchoring a suture to a bone or similar structure, comprising:
-
an elongate body having first and second ends, a central portion between said ends, a longitudinal axis extending through each of said ends, and a transverse axis extending through the central portion of the body and intersecting the longitudinal axis at an acute angle; and means for attaching the suture to the central portion of the body, said means comprising a passage which extends through said body and coaxially with said transverse axis, said passage defining two openings on substantially opposite sides of the body; wherein said first end is formed as a point which is offset from the longitudinal axis in generally opposing relation to the nearer of said two openings. - View Dependent Claims (25, 26)

27. A method of securing a suture to a bone using a device which comprises an elongate body having first and second ends, a central portion between said first and second ends, and means for attaching the suture to the central portion at a point which is offset from a longitudinal axis which extends through the first and second ends, comprising the steps of:
-
a. forming a hole which extends through a cortical layer of the bone and into a cancellous portion of the bone to a depth which at least equals a length of the elongate body of the securing device; b. inserting the device and attached suture into the hole such that the outwardly facing end of the device is disposed inwardly of an inner cortical wall of the bone; and c. pulling the suture to cause the device to rotate such that the first and second ends penetrate the relatively soft cancellous portion of the bone and come to rest substantially adjacent the inner wall of the relatively hard cortical bone so as to secure the suture in place.

28. A method of securing a suture to a bone using a device which comprises an elongate body having first and second ends, a central portion between said first and second ends, a sharp point on said first end, and means for attaching the suture to the central portion at a point which is offset from a longitudinal axis which extends through the first and second ends, comprising the steps of:
-
a. forming a hole in the bone having a depth which at least equals a length of the elongate body of the securing device; b. inserting the device and attached suture into the hole; and c. pulling the suture to cause the device to rotate and the sharp point to penetrate the bone so as to prevent the device and suture from being removed from the hole.

29. In combination, a suture and a device for attaching the suture to a bone, comprising:
-
a relatively rigid, elongate body having first and second ends, a central portion between said ends, and a longitudinal axis extending through said ends, at least one of said first and second ends being adapted to engage the bone; and means for attaching the suture substantially midway between the first and second ends of the body at a point which is offset from the longitudinal axis so that, when the device is placed in a hole in the bone and a force having a component acting in a direction which is parallel to the longitudinal axis of the device is applied to the suture, the device will rotate causing the end to engage the bone and prevent removal of the device and suture from the hole.
