Method of securing body tissue
DCFirst Claim
1. A method of securing first body tissue with second body tissue, said method comprising the steps of moving a first anchor along a first path into the second body tissue, moving a second anchor along a second path into the second body tissue, said steps of moving the first and second anchors along first and second paths include moving the first and second anchors along first and second paths which intersect in the second body tissue, connecting the first and second anchors together at the intersection between the first and second paths in the second body tissue, and transmitting force through the suture to the first body tissue.

Abstract
To secure a first body tissue with a second body tissue, a first anchor is moved along a first path through the first body tissue into the second body tissue. A second anchor is moved along a second path through the first body tissue into the second body tissue. A suture extending between the anchors may be tightened by moving the second anchor along a path which extends transverse to the path of the first anchor. The suture which extends between the anchors may have free ends which are connected with a suture retainer. The free ends of the suture may be interconnected either before or after the anchors are moved along the first and second paths. Alternatively, the suture may be a continuous loop which extends between the two anchors. A guide assembly may be provided to guide movement of the anchors along the two paths. The paths along which the anchors move may intersect so that the anchors may be interconnected at the intersection between the two paths.

- 10. A method of securing first body tissue with second body tissue, said method comprising the steps of moving a first anchor along a first path into the second body tissue with a suture extending between the first anchor and a second anchor, moving the second anchor along a second path into the second body tissue with the suture extending between the first anchor and the second anchors, determining when a predetermined tension is present in the suture, and transmitting force through the suture to the first body tissue.
- 35. A method of securing first body tissue with second body tissue, said method comprising the steps of moving a first anchor along a first path into the second body tissue with a first suture portion extending from the first anchor, moving a second anchor along the second path into the second body tissue with a second suture portion extending from the second anchor, tensioning the first and second suture portions, determining when a predetermined tension is present in the first and second suture portions during performance of said step of tensioning the first and second suture portions, interconnecting the first and second suture portions after determining that the predetermined tension is present in the first and second suture portions, and transmitting force through the suture to the first body tissue.
- 45. A method of securing first body tissue with bone, said method comprising the steps of moving a first anchor along a first path with a first suture portion extending from the first anchor, said step of moving the first anchor along the first path includes engaging a trailing end portion of the first anchor with a pusher, piercing the first body tissue with a leading end portion of the first anchor at a location ahead of the pusher which engages the trailing end portion of the first anchor as the first anchor moves along the first path with the first suture portion extending from the first anchor, piercing a hard outer layer of the bone with the leading end portion of the first anchor at a location ahead of the pusher which engages the trailing end portion of the first anchor as the first anchor moves along the first path with the first suture portion extending from the first anchor, piercing cancellous bone enclosed by the hard outer layer of the bone with the leading end portion of the first anchor at a location ahead of the pusher which engages the trailing end portion of the first anchor as the first anchor moves along the first path with the first suture portion extending from the first anchor, moving a second anchor along a second path with a second suture portion extending from the second anchor, said step of moving the second anchor along the second path includes engaging a trailing end portion of the second anchor with a pusher, piercing the first body tissue with a leading end portion of the first anchor at a location ahead of the pusher which engages the trailing end portion of the second anchor as the second anchor moves along the second path with the second suture portion extending from the second anchor, piercing the hard outer layer of the bone with the leading end portion of the second anchor at a location ahead of the pusher which engages the trailing end portion of the second anchor as the second anchor moves along the second path with the second suture portion extending from the second anchor, piercing the cancellous bone enclosed by the hard outer layer of the bone with the leading end portion of the second anchor at a location ahead of the pusher which engages the trailing end portion of the second anchor as the second anchor moves along the second path with the second suture portion extending from the second anchor, tensioning the first and second suture portions with the first and second suture portions extending across at least a portion of the first body tissue disposed between the first and second paths, and transmitting force from the first and second suture portions to at least a portion of the first body tissue disposed between the first and second paths, said step of transmitting force from the first and second suture portions to at least a portion of the first body tissue between the first and second paths includes transmitting force between the first and second anchors through the first and second suture portions.
-
46. A method as set forth in 45 further including the step of interconnecting the first and second suture portions at a location between the first and second paths to enable force to be transmitted between the first and second suture portions.
-
47. A method as set forth in 45 wherein the first and second suture portions are interconnected during performance of said step of moving the second anchor along the second path, said step of tensioning the first and second suture portions includes moving at least one of the first and second anchors along at least one of the first and second paths.
-
48. A method as set forth in 45 wherein the first and second suture portions are interconnected to form a continuous loop which extends between the first and second anchors.
