  • Patent number: 12256912
    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: 20250049465
    Abstract: A system for harvesting a tendon graft is disclosed, the system including a retractor, a guide and at least one harvesting tool. The retractor holds open an anatomic space in a patient above the tendon. The guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. A first harvesting tool and the guide include a plurality of surfaces that cooperate with each other to transect the tendon and form at least one side of the tendon graft, the plurality of surfaces cooperating to limit a trajectory and a depth of cut into the tendon and also limiting both ends of the translational extent of the harvesting tool along the tendon. A second harvesting tool may extend along the anatomic space formed by the retractor and form both a posterior cut along the tendon and transect a tendon graft end.

  • Publication number: 20250049448
    Abstract: In one embodiment of the present disclosure a method may include presenting, on a user interface, a single aimer indicator to identify when a first parameter of a tool is satisfied, wherein the first parameter pertains to a first axis associated with the tool. The method may include modifying a first aspect of the single aimer indicator to identify when a second parameter of the tool changes, wherein the second parameter pertains to a second axis associated with the tool. The method may include determining when a threshold associated with the second parameter is satisfied. Responsive to determining the threshold associated with the second parameter is satisfied, the method may include modifying a second aspect of the single aimer indicator to represent the tool is in coaxial alignment.

  • Patent number: 12207808
    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.

  • Patent number: 12138679
    Abstract: A single-patient-use disposable tool comprises a molded, single-piece body with a curved upper surface having a predetermined bend radius for bending a needle slidably disposed in a sheath. A distal end of the curved surface has a slot for insertion of a tip of a needle, while the proximal end of the curved surface has a guide member for slidably receiving the sheath. Two finger loops or similar ergonomic features allow the user to rotate the bending tool relative to the sheath to bend the needle about the predetermined bend radius. After completing the bend, the tool is removed from the needle and disposed of.

  • Patent number: 11903593
    Abstract: An anchor delivery system includes both a straight and curved drill guide along with a flexible drill, a flexible obturator and a flexible anchor inserter. The curved drill guide has a distal tip with approximately a 15° bend from the primary axis of the drill guide. Both the drill and the obturator have a reduced diameter section to improve flexibility during passage through the curved drill guide. Additionally, a surface of the inserter shaft has a laser cut pattern which permits flexing of the inserter around the inner diameter of the curved drill guide.

  • Patent number: 11712255
    Abstract: Surgical drill guides having a guide shaft and a set of distal guide teeth extending from the guide shaft. The guide shaft has proximal and distal portions having two distinct inner and outer diameters, with a tapered zone extending between the two portions. Wall thickness is maintained or increased from the proximal portion to the distal portion of the shaft, reinforcing the rigidity of both the shaft and the distal guide teeth.

  • Publication number: 20230109413
    Abstract: Depth penetration limiters for use with meniscal repair devices which have a built-in, self-stopper feature to prevent the limiter from disengaging from the device housing. The self-stopper feature is a cantilevered flexure on a bottom surface of the limiter that deflects as it is moved through the housing. As the flexure passes the edge of a recess in the housing, the flexure returns to its original shape, trapping the flexure within the recess and preventing further distal movement of the limiter/depth tube. A connection feature on the limiter provides increased pull-off resistance of the depth tube from the limiter.

  • 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.
