INTERVERTEBRAL DISC ANNULUS REPAIR SYSTEM AND BONE ANCHOR DELIVERY TOOL
First Claim
1. An intervertebral disc repair system comprising:
- an implant including an anchor member and an adjustable suture assembly coupled thereto, the adjustable suture assembly forming an adjustable loop and including a tension line having a proximal end, and a toggle line coupled to the anchor member for selectively rotating the anchor member during deployment thereof; and
a delivery tool including;
a proximal handle,an outer tubular member extending distally from the handle and having an open distal end,a needle cannula slidably received within the outer tubular member having a proximal portion with a proximal end, and an open distal end terminating with a sharpened tip for penetrating tissue,an inner pusher member slidably received within the needle cannula and having a proximal end and a distal end, andan actuating mechanism coupled to the handle for selectively retracting the needle cannula relative to the outer tubular member and the inner pusher member,wherein the proximal end of the tension line of the implant is operable by the user to reduce at least one dimension of the loop,wherein the anchor member and at least a portion of the adjustable suture assembly of the implant are releasably received within the needle cannula distal to the distal end of the inner pusher member,wherein the delivery tool is configured such that actuation of the actuating mechanism proximally retracts the needle cannula relative to the outer tubular member and the inner pusher member to release the anchor member from the needle cannula, andwherein the toggle line of the adjustable suture assembly of the implant is operable to cause rotation of the anchor member as the anchor member is released from the needle cannula.

Abstract
An intervertebral disc repair system comprises an implant and a delivery tool configured to deploy the implant at least partially in a vertebral body of a patient. The implant includes an anchor member and an adjustable suture assembly coupled thereto. The delivery tool includes a proximal handle, an outer tubular member extending distally from the handle, a needle cannula slidably received within the outer tubular member having a sharpened tip for penetrating tissue (e.g., the vertebral body), an inner pusher member slidably received within the needle cannula, and an actuating mechanism coupled to the handle for selectively retracting the needle cannula relative to the outer tubular member and the inner pusher member. At least the anchor member of the implant is releasably received within the needle cannula.

11. An intervertebral disc repair system for repairing a defect in an intervertebral disc of a patient, the system comprising:
-
a first implant including first and second tissue anchors, and an adjustable connecting element connecting the first and second tissue anchors, the adjustable connecting element having an adjustable length between the first and second tissue anchors; a first delivery tool including a tissue penetrating tubular member, the first and second tissue anchors releasably received in the tubular member, the first delivery tool configured to deploy the first and second tissue anchors in the intervertebral disc; a second implant including an anchor member and an adjustable suture assembly coupled thereto, the adjustable suture assembly forming an adjustable loop and including a tension line having a proximal end operable by a user to reduce at least one dimension of the adjustable loop, and a toggle line coupled to the anchor member for rotating the anchor member during deployment thereof; and a second delivery tool including a proximal handle, an outer tubular member extending distally from the handle and having an open distal end, a needle cannula slidably received within the outer tubular member having a proximal portion with a proximal end and an open distal end terminating with a sharpened tip for penetrating tissue, an inner pusher member slidably received within the needle cannula and having a proximal end and a distal end, and an actuating mechanism coupled to the handle for selectively adjusting an axial position of the needle cannula relative to the outer tubular member and the inner pusher member, wherein the anchor member and at least a portion of the adjustable suture assembly of the second implant are releasably received within the needle cannula of the second delivery tool, wherein the toggle line of the adjustable suture assembly of the second implant is operable to cause rotation of the anchor member during deployment thereof upon actuation of the actuating mechanism by a user, and wherein the adjustable suture assembly and the connecting element are configured to be interconnected and placed under tension after deployment of the anchor member and the first and second tissue anchors. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A tissue repair system comprising:
-
an implant including an anchor member and an adjustable suture assembly coupled thereto, the adjustable suture assembly forming an adjustable loop and including a tension line having a proximal end, and a toggle line coupled to the anchor member for selectively rotating the anchor member during deployment thereof; and a delivery tool including; a proximal handle, an outer tubular member extending distally from the handle and having an open distal end, a needle cannula slidably received within the outer tubular member having a proximal portion with a proximal end, and an open distal end terminating with a sharpened tip for penetrating tissue, an inner pusher member slidably received within the needle cannula and having a proximal end and a distal end, and an actuating mechanism coupled to the handle for selectively retracting the needle cannula relative to the outer tubular member and the inner pusher member, wherein the proximal end of the tension line of the implant is operable by the user to reduce at least one dimension of the loop, wherein the anchor member and at least a portion of the adjustable suture assembly of the implant are releasably received within the needle cannula distal to the distal end of the inner pusher member, wherein the delivery tool is configured such that actuation of the actuating mechanism proximally retracts the needle cannula relative to the outer tubular member and the inner pusher member to release the anchor member from the needle cannula, and wherein the toggle line of the adjustable suture assembly of the implant is operable to cause rotation of the anchor member as the anchor member is released from the needle cannula.
