A catheter device (102) for repair of the heart by implanting an artificial chordae line (114), the catheter device (102) comprising: a housing section extending from a distal end of the catheter device along the length of the catheter device toward a proximal end of the catheter device; a leaflet anchor (110) for placement in a leaflet (12) of a heart valve, wherein the leaflet anchor (110) is arranged to be coupled to the artificial chordae line (114); and a leaflet anchor deployment mechanism for deploying the leaflet anchor (110) to attach it to the leaflet (12) of the heart, wherein the leaflet anchor deployment mechanism comprises a mechanical gripper device (106) for grasping the leaflet (12) of the heart valve, and a leaflet anchor tube (138) for housing the leaflet anchor (110) in a folded configuration; the gripper device (106) and leaflet anchor (110) being arranged such that when, in use, the gripper device (106) grasps the leaflet (12), the leaflet anchor (110) can be pushed out of a leaflet anchor tube (138) to pierce the leaflet (12) and form the leaflet anchor (110) into an unfolded configuration so that hooked formations of the leaflet anchor (110) can, in use, secure the leaflet anchor (110) in the leaflet (12); wherein the mechanical gripper device (106) includes a gripper arm (130) rotatably coupled to a main body of the catheter device (102) so that the gripper arm (130) can rotate relative to the catheter device (102) to move an outer end of the gripper arm (130) away from the main body of the catheter device (102); and wherein the leaflet anchor tube (138) is arranged to implant the leaflet anchor (110) in the leaflet (12) of the heart by piercing the leaflet (12) from an atrial side of the leaflet (12).

Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

Various devices, systems and methods for knotless anchoring of sutures to repair bodily tissue are disclosed. These devices allow sutures to be anchored to bone or other tissues, and more specifically provide a suture anchor which eliminates the need for the operator to knot the suture to secure the suture under tension. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts and find particular utility in hip and shoulder arthroscopy, e.g. labral reattachment, rotator cuff repair, and similar procedures.

A suture anchor retaining a suture is fixated in hard tissue, in particular in bone tissue, using any per se known method and is then secured using a securing element including a material having thermoplastic properties, which is liquefied in situ and made to penetrate the hard tissue in which the suture anchor is fixated. The securing element is e.g. a thermoplastic plug or thermoplastic sleeve which is anchored above the suture anchor in a mouth area of the same hard tissue opening. Alternatively the securing element is a thermoplastic pin which is introduced into an inner cavity of the suture anchor, wherein the material having thermoplastic properties is liquefied in this cavity and, in a liquid state is pressed through passages connecting the cavity with outer surfaces of the anchor.

A knotless button includes a body defining a proximal portion and a distal portion. The body further defines an internal cavity and a first loop opening extending from the internal cavity to an outer surface of the body. A locking insert is slideably positioned within the internal cavity. The locking insert defines a second loop opening extending from a first side of the locking insert to a second side of the locking insert. The locking insert is slideably moveable from a first position to a second position within the internal cavity. A flexible strand defines a first adjustable loop extending through the first loop opening and the second loop opening. The locking insert is slideably moveable from a first position configured to allow adjustment of the first adjustable loop to a second position configured to lock the first adjustable loop.

A suture anchor for knotless fixation of tissue. A swivel suture anchor has an anchor tip for receiving a suture strand, for surgical tissue repair without requiring suture knots. Tension on the repair constructs is adjustable. The swivel anchor is secured in a hole in bone by advancing a fixation device, such as a cannulated interference screw, over the body of the anchor.

Biodegradable and bioabsorbable anchors and anchor systems for use in musculoskeletal fixation applications comprising (1) an anchor body comprising a longitudinal axis, a proximal end, a distal end, an outer surface, and a bore extending from the proximal end and parallel to the longitudinal axis, wherein the bore defines an inner surface of the anchor body, and wherein at least a portion of the anchor body is expandable in a direction non-parallel to the longitudinal axis, and (2) an expansion pin comprising a longitudinal axis, a proximal end, a distal end, and a surface, and configured for insertion into the bore such that, when inserted, it expands the expandable portion of the anchor body in a direction non-parallel to the longitudinal axis. Both the disclosed anchors and anchor systems are at least in part formed from a citrate-based polymer.

A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.

Knotless surgical constructs and methods of tissue repairs. A surgical construct can offer both repair and shuttling capabilities to allow for a single pass to load multiple sutures at once. A surgical construct is in the form of a flat suture tape provided with reinforced perforations and/or shuttling loops that can pass or shuttle multiple repair sutures while making a single pass through or around soft tissue.

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.
