  • Publication number: 20240081808
    Abstract: Methods and devices for tissue fixation. A cortical button with a rib between two slotted openings. The rib increases the cortical button structural rigidity without increasing palpability. An adjustable loop construct with two discrete locking passages that provides manageable loop reduction and improved tissue coupling. The adjustable loop construct may be coupled to tissue via a passing construct. An assembly with a reduction bar, a button and an adjustable loop construct, the assembly provided assembled in a first configuration that disassembles to guide steps of tissue fixation. The reduction bar may be assembled to the reduction bar for reducing the adjustable loop construct.

  • Publication number: 20220409192
    Abstract: A harvesting assembly for harvesting a tissue graft from surrounding tissue is disclosed including a guide. The guide includes a means for fixedly engaging with an anterior surface of the tendon. The guide also includes a means of guiding a cutting blade along a preferred trajectory into and along a length of the tendon. The guide also includes a means of guiding a truncating blade along a preferred trajectory across a width of tendon. The cutting blade may include two parallel blades for forming lateral sides of the tendon graft simultaneously. Each of the two parallel blades may define a leading edge that extends along at least a 90 degree arc that is equidistant from a stop on the cutting blade. The stop in combination with the guide may limit a cut depth into the tendon for a range of cutting blade handle elevation angles.

  • Publication number: 20220167954
    Abstract: A system for improving graft harvesting including a blade guide (320) having a handle (370) and a guide portion with an elongate slot (330). The system may also include a first blade assembly (750) that slides along the elongate slot (330), the blade assembly (750) having a cutting blade (765) rotatably coupled to a handle (780). The cutting blade (765) may include a leading cutting edge and a trailing cutting edge. The blade assembly (350, 750) and blade guide (320) may cooperate to control a depth of blade penetration into a tissue, as the blade slides along the elongate slot (330). The blade guide (320) may include means to stabilize the guide with the tissue.

  • Publication number: 20210346148
    Abstract: An adjustable fixation system for coupling a tissue or graft to bone is disclosed including a suture construct including a first limb, a second limb and a body therebetween. The body is continuously braided with the first and second limbs and has a longitudinal passage therethrough. The first and second limbs define a braided portion including a braided core. The suture construct is configured to form at least one adjustable loop formed by passing the first limb between braids of the suture construct, along the longitudinal passage and back out between braids of the adjustable suture construct. Tension on at least one of the first or second limbs reduces a diameter of the longitudinal passage around a length of the first limb and thereby the braided core disposed along the body longitudinal passage and knotlessly locks the adjustable loop.
