The present invention provides knotless suture anchor systems and devices for attaching soft tissue to bone. The systems and devices include suture anchors configured to engage and fasten sutures using set screws such that the locked sutures are free from frictional engagement with bone, screw threading, or internal walls of the anchors and set screws. Fastened sutures may also be re-tensioned by loosening a set screw to unfasten the sutures, adjusting the positioning of the sutures, and tightening the set screw to refasten the sutures. In some embodiments, the systems and devices enable the insertion of a suture anchor without preloading sutures, such that one or more sutures may be fastened to the suture anchor after implanting the suture anchor into a subject.

In one embodiment, an adjustable implant system includes a bone anchor having first and second ends, a bone engagement surface adjacent the first end, and a housing extending between the first and second ends. The adjustable implant system can further include a non-invasively actuatable driving element within the housing and coupled to an adjustment component configured to couple to a flexible elongate tension member which is capable of engaging a patient's soft tissue (e.g., rotator cuff or ACL). Non-invasive actuation of the driving element can cause the adjustment component to change the amount of tension on the flexible elongate tension member and consequently on the patient's soft tissue. The adjustable implant system can include an external adjustment device configured to be placed on or adjacent the patient's skin and comprising at least one energy transferring component configured to energize/actuate the driving element inside the housing of the adjustable implant.

The invention described is comprised of a system and method for rapid fixation of a lead anchor. The system includes a lead anchor and insertion device. The insertion device houses a lead anchor. A lead is threaded through the insertion device and the device is depressed against the fascia to insert the lead anchor and fix the lead in the desired position. This method produces repeatable amount of lead body compression grasp force, and controlled bend radius. This results in rapid lead anchoring, lowers the risk of lead migration, prevents mechanical damage to the lead due to over-compression and eliminates the need for tying a suture.

A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.

Improved suture anchor systems and methods of use are disclosed herein. The suture anchor may have proximal and distal ends, and first and second lateral sides extending between the proximal end and the distal end. A centrally located suture passage may extend through the anchor body from a first opening in the first lateral side to a second opening in the second lateral side. A channel may extend along a longitudinal axis of the anchor body. The insert may be configured to translate longitudinally within the channel between the proximal end of the anchor body and the distal surface of the suture passage. There may also be provided a surgical broach adapted for use with the suture anchor system.

This disclosure relates to expandable implants and methods of using expandable implants for tissue fixation and repair.

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.

Apparatus and methods are described herein for anchoring a prosthetic heart valve. In some embodiments, an apparatus includes a tether attachment member that includes a base member that defines at least a portion of a tether passageway through which a portion of a tether extending from a prosthetic heart valve can be received therethrough. The base member defines a locking pin channel that intersects the tether passageway. A locking pin is disposable within the locking pin channel and movable between a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and can engage the portion of a tether disposed therein to secure the tether to the tether attachment member.

A suture anchor assembly is disclosed herein. The assembly includes an anchor body for anchoring within a target tissue, the anchor body including a proximal connecting portion. The assembly also includes an insertion instrument for inserting the anchor body within the target tissue. The insertion instrument includes a connecting portion at a distal end thereof that interdigitates with the anchor body connecting portion to provide rotational stability between the anchor body and insertion instrument. The connecting portions, when assembled, forms a tubular shape with a shared inner diameter and a shared outer diameter. The shared inner diameter defines a cannulation that received a plug therethrough. The plug may axially advance into the anchor body, to knotlessly lock a suture of the suture anchor assembly.
