A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.

Surgical filament snare assemblies

Knotless suture anchors and methods are provided for affixing soft tissue to a bone. One exemplary embodiment of a suture anchor includes an insertion rod, a distal tip member removably coupled to a distal end of the insertion rod, the distal tip member having a suture engagement feature configured to have a plurality of suture limbs slidably coupled to the tip member, and a proximal main member having an elongated cylindrical body with one or more bone-engaging features disposed on its outer surface and a longitudinal lumen extending from a proximal end to a distal end. The suture anchor can also include two suture limb holding surfaces to maintain two suture limbs a distance apart from each other. Other exemplary embodiments, as well as methods for affixing soft tissue to a bone, are also provided.

Knotless instability devices and methods for soft tissue repair

Systems are provided for securing tissue to bone. A suture anchor can include an elongate body having a proximal end and a distal end and an external surface with a plurality of longitudinally spaced bone-engaging features formed at least partially circumferentially thereon over at least a portion of a length of the suture anchor. The proximal end can have a lumen extending at least partially into the elongate body and the distal end can have a suture engaging feature proximate thereto. A first series of bone-engaging features can have a dimension that increases from a distal to a proximal end of each bone-engaging feature of the first series of bone-engaging features. A second series of bone-engaging features can have a dimension that decreases from a distal to a proximal end of each bone-engaging feature of the second series of bone-engaging features.

Knotless suture anchors

Meniscal repair devices, systems, and methods are provided.

Meniscal repair devices, systems, and methods

Various devices, systems, and methods are provided for securing soft tissue to bone. In one exemplary embodiment, a two-piece inserter tool is provided that includes a tip portion that is configured to be removably coupled to a handle portion. A distal portion of the tip portion can be configured to be coupled to a suture anchor, and the tip portion and the anchor can be passed through a continuous suture loop prior to mating the tip portion to the handle portion.

Multi-piece anchor inserter

Methods and devices for fixation of soft tissue to bone are provided. In one embodiment, a suture anchor is provided having an elongate cylindrical body with proximal and distal ends and an inner lumen extending therethrough. The elongate body can be configured so that upon partial insertion into a bone hole, it is securely anchored within the bone hole and a suture extending through the inner lumen is freely slidable. It can also configured so that, upon further insertion into the bone hole, at least a portion of the elongate body compresses to lock the suture within the inner lumen such that the suture is prevented from sliding. In another embodiment, a suture anchor is provided having arms that have an open position for receiving a suture therebetween, and a closed position in which the suture is retained but allowed to slide freely.

Suture anchor system with compressible distal tip

Devices, systems, and methods are provided for managing suture filament during a tissue repair procedure. One exemplary embodiment of an anchor insertion tool includes a handle, an elongate shaft extending distally from the handle, and a ring disposed around the elongate shaft. The ring can be configured to slide along a length of the shaft, and can be configured to engage a filament extending from an anchor removably coupled to the shaft's distal end during a suture anchor insertion procedure. In some embodiments, the ring can include one or more slots for receiving a filament and maintaining a tension applied to the filament. The ring can also include features that prevent it from rotating with respect to the shaft, such as a boss formed on a ring's central opening that engages a slot formed in the shaft. Other devices, systems, and methods for suture anchor insertion are also provided.

Devices, systems, and methods for suture management

Methods, systems, and devices are provided for guiding surgical instruments using radio frequency (RF) technology. In general, the methods, systems, and devices can allow a trajectory, e.g., an angular approach, of a surgical instrument relative to a patient to be identified during use of the instrument in a surgical procedure being performed on the patient. The trajectory can be identified using a plurality of RF modules. The methods, systems, and devices can allow the trajectory to be compared to a predetermined trajectory so as to identify whether the trajectory matches the predetermined trajectory. A result of the matching can be communicated to a user of the instrument. Based on the result, the user can maintain the trajectory, e.g., if the trajectory matches the predetermined trajectory, or can adjust the trajectory to closer align the trajectory with the predetermined trajectory, e.g., if the trajectory does not match the predetermined trajectory.

Methods, systems, and devices for guiding surgical instruments using radio frequency technology

A trans-soft tissue anchor implantation system in one embodiment includes a positioning wire having a tissue penetrating distal tip, a cannula for passage through the soft tissue and a suture anchor. The cannula has an axial lumen therethrough sized to accommodate at least the positioning wire, a thin-walled distal portion and a tissue engaging feature, such as an arcuate groove, on at least a portion of an outer surface of the cannula proximal of and adjacent to the distal portion. Tissue, such as a tendon, expands into the groove allowing a surgeon to manipulate the tissue with the cannula. Also featured is a cannula having a first curved section having a first thin-walled distal portion and a second curved section having a second thin-walled distal portion, the first and second curved sections capable of being moved relative to each other from an initial, low-profile configuration, with the second section nesting at least partially within the first section to present less than a full circumference of cannula to the soft tissue, to a second, larger configuration defining an axial cannula lumen therethrough.
