A surgical filament securement assembly has an anchor having a channel therethrough through which a surgical filament is passed. The surgical filament is tied to form a dilated knot having at least one throw around a dilater member at an entrance of the channel such that the surgical filament is able to run around the dilater member when a limb thereof is pulled in a first direction through the channel whilst the dilated knot remains in place. When the dilater member is pulled out from within the dilated knot, the dilated knot itself strangulates to form a tightened stopper knot. The channel has a diameter less than that of the tightened stopper knot such that the tightened stopper knot cannot pass through the entrance in the first direction.

An apparatus and method is disclosed for securing tissue to a bone comprising a novel screw anchor for insertion into a bone by a novel rotational driver. The screw anchor and rotation driver enables the screw to be completely embedded into the bone while permitting a suture to be threaded through a transverse aperture in the screw. The rotation driver facilitates insertion and engagement of a capture with one of a series of protuberance formed along a length of a suture. In addition, the method is disclosed of forming the series of protuberance.

Disclosed herein is a device and method for securing soft tissue such as the long head of the biceps tendon (or similar) as well as free grafts or allografts directly to bone. The device is directly crimped to the preferred soft tissue. This is accomplished by the application of a crimping device to the implantable device and application of sufficient force to crimp the implantable device thereby fixing said device to the tissue in question. The complex of the device and the tissue/tendon can then be directly fixed to bone as necessary. Additionally, the same device and method can be used to connect one tendon to another as indicated.

An anchor device for attaching suture material to bone includes a body portion having a first end and a second end. The body portion includes a trabecular mesh core that at least partially defines a central bore between the first end and the second end. The trabecular mesh core includes a plurality of openings configured to receive/allow/facilitate bone growth through the trabecular mesh core. The body portion also includes at least one thread extending spirally along an exterior of the trabecular mesh core. The anchor device further includes a post at least partially positioned within the central bore and rotatably coupled to the body portion, wherein the post comprises a fork extending from the second end of the body portion and configured to attach soft tissue to the bone using the suture material. The body portion and the post are additively manufactured from a biocompatible material.

A setting assembly for a clamped fixation of a tissue strand, such as a tendon or a band in particular, to a securing recess, which is recessed into a bone, has a clamping element which has a clamping section that tapers along a central axis of the clamping element towards a first end, a recess that is provided on a second end facing away from the first end for passing through the tissue strand, and a tool receiving area that is recessed onto the first end and has a first contact for applying a force acting in a pushing direction and a second contact for applying a force acting in a pulling direction opposite the pushing direction. The setting assembly additionally has an applicator which has an insertion end for releasably connecting to the tool receiving area, the insertion end having a first mating contact which can be placed against the first contact and a second mating contact which can be placed against the second contact means. The tool receiving area has first and second rotation locks, and the insertion end of the applicator has a rotating device which can be placed against the first and second rotation locks in a first rotational direction and a second rotational direction opposite the first rotational direction in order to transmit first and second torques.

Cartridges configured to hold anchors and associated locking sutures and a common suture used in an array of anchors. A suture anchor array is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a suture lock having a free tail that can be pulled to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture bridge between each implanted suture anchor and the just previously implanted anchor. The cartridges are configured to securely hold an individual anchor and store the tail of the suture lock, while allowing flossing of anchors along the common suture.

A delivery device for transtendinous implantation of a toggle-type suture anchor into bone is disclosed. The device includes a proximal housing having an outer tubular shaft extending distally with a lumen therethrough. An anchor delivery tube extends through the lumen of the outer tubular shaft having a proximal end affixed to the proximal housing. The anchor delivery tube includes a nub portion that is used to insert through the tendon and partly into bone to maintain registration with a bone hole into which an anchor is placed. A bone punch assembly extends through the lumen of the anchor delivery tube and the nub portion with a pointed distal end. When the bone punch is fully inserted, the pointed distal end extends a distance distal of the distal end of the nub portion.

Compression anchor systems, devices, instruments, implants, and methods for using the compression anchor systems, devices, instruments, and implants are disclosed. The compression anchor system including an implant and a suture anchor. The compression anchor system may also include an inserter for engaging the implant and receiving at least a portion of the suture anchor. The implant may include a threaded head and a shaft with at least one thread portion and at least one anchor portion. Finally, methods for assembling and surgically inserting the anchor system are also disclosed.

Fixation assemblies having a button captured by a continuous (i.e., closed) loop of thread, such as ultra high molecular weight polyethylene (UHMWPE) fiber are disclosed herein. Preferred assemblies are constructed such that the intact button cannot be detached from the continuous loop without breaking or opening the loop of fiber. The closed fiber advantageously contains at least one or two stitched, or otherwise secured or reinforced, sections positioned on the loop.

Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.
