Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more structured tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture and can be useful in many different tissue repair procedures that are disclosed in the application. The present disclosure includes structured tissue augmentation blocks for tendon repair that have a flexible or semi-flexible skeleton integrated into the block. The skeleton can be bioabsorbable and can create both in-plane and out-of-plane curvature in the block.

Systems and methods for using structured tissue augmentation constructs in soft tissue fixation repair

Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a suture anchor is provided that includes one or more bone-engaging surfaces features and an external sidewall. The external sidewall can allow a suture coupled to the suture anchor and located between the anchor and bone to be movable relative to the suture anchor, even when the suture anchor is partially or fully disposed within a bone hole. Suture threaders and suture anchor drivers are also provided that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.

Knotless instability anchor

Various exemplary surgical fasteners are provided, and methods and devices are provided for deploying a surgical fastener. In general, the methods and devices allow a surgical fastener to be deployed to secure tissue to bone. In one embodiment, a surgical fastener can be configured to move between a first linear or compressed configuration, in which the fastener can have a first maximum diameter, and a second bent or expanded configuration, in which the fastener can have a second maximum diameter greater than the first maximum diameter. A delivery device can be configured to advance the fastener through tissue and into bone to attach the tissue to the bone. The delivery device can be configured to maintain the fastener in the compressed configuration such that when the fastener is released from the delivery device, the fastener can be configured to self-expand from the compressed configuration to the expanded configuration.

Surgical fasteners and methods and devices for deploying a surgical fastener

Devices, systems, and methods are provided for managing suture filaments when performing soft tissue repair. One exemplary embodiment of a surgical suture management device is in the form of a suture loop management card. The card can generally be configured to hold open a collapsible loop of suture until a force applied to the loop is greater than a threshold tension. The card can include a number of different features that help to keep the loop open until the threshold tension is achieved, including features designed to prevent the filament from being mistakenly offloaded. The card can be configured to be removably inserted into a handle of an inserter tool for use as a surgical tissue repair system. Other devices, systems, and methods for performing soft tissue repair are also provided.

Suture storage devices, systems, and methods

A method of compacting and stabilizing bone in the spine using an expandable screw and bone filler. The method includes placing an expanding screw through a pedicle and into a fractured vertebral body using established techniques; and expanding the screw within the body to create a cavity by tamping bone around the expanded aspect of the screw. The screw can be expanded and rotated about its rotational-axis to tamp bone adjacent to the expanded screw. After compaction, the screw is removed and the cavity is filled with bone filler.

Expansion screw bone tamp

A spinal implant insertion device is hereby provided. The device includes an insertion blade assembly having a set of opposed insertion blades wherein the assembly is adapted to slide from a retracted position to an extended position relative to an elongate shaft. In the extended position, a blades are adapted to be positioned above and below a portion of a spinal implant so as to shield the portion of the implant during delivery to an intervertebral space. The insertion blades assembly can also be modular so as to utilize a wide range of distinct insertion blades. Additionally, a method for delivering a spinal implant to an intervertebral space is herein provided. Like above, the method utilizes an insertion blade assembly adapted to slide along a shaft of a spinal implant insertion device.

Insertion blade assembly and method of use

Methods and devices for locking a fastener in a thru-bore are provided herein. In one exemplary embodiment, a spinal anchor is provided that includes a bone engaging fastener, an anti-backout mechanism, and a locking mechanism. The anti-backout mechanism can be movable between a retracted position in which it is disposed within the fastener and a deployed position in which is extends from the bone engaging fastener. The locking mechanism can be matable to the bone engaging fastener and can be configured to move the anti-backout mechanism from the retracted position to the deployed position. In the deployed position, the anti-backout mechanism can prevent the bone engaging fastener from backing out of a thru-bore in a spinal plate.

Anti-backout mechanism

An intervertebral disc prosthesis comprises a first plate including a socket and a second plate comprising a recess. A core is sandwiched between the socket and the recess. The core includes a domed surface and a plug portion. The first plate is configured to rotate upon the domed surface of the core. The second plate is substantially fixed to the core, with the plug portion engaging the recess. The core may be press-fit into the second plate during assembly of the intervertebral disc prosthesis. The first plate and second plate both include tabs that define notches, wherein the notches are configured to engage prongs of a disc insertion tool. Teeth provided on the first plate and the second plate assist in fixing the first plate and the second plate to the vertebral bodies.
