6 results about "Meniscal repairs" patented technology

A system for repairing tears in soft tissue, e.g., meniscal tissue, by employing cinch stitching. More specifically, the present invention provides an apparatus for meniscal repair using a suture implant construct. The suture implant construct includes a first and second implant which are connected to each other via a length of suture. The implants are designed to be loaded on external surfaces of the first and second trocars.

A meniscal repair device comprises a main gripping body provided with a distal end and a proximal end, an actuating element movable on the main body, adapted to move a surgical needle, insertable in the main body, between an initial position of first engagement to a final position of complete release. The device further comprises a cannula, within which the needle slides, comprising a respective proximal end connected to the distal end of the main body and a respective distal end through which the needle exits. The main body is longitudinally passed through by a central passage from the proximal end, at which an inlet hole is provided, to the distal end at which an interconnection hole is provided with the cannula, so that the inlet hole, the interconnection hole and the cannula are in fluid communication. The device further comprises a fastening mechanism actuatable independently of the movement of the actuating element and selectively positionable in an unlocked position, at which the needle is released from the actuating element, and a locked position, at which the needle is constrained to the actuating element.

A tissue repair device includes a pusher assembly including a rod portion configured to be advanced through a needle to expel a first implant and a second implant from the needle, a ratchet coupled to a proximal section of the rod portion and configured to advance the rod through the needle by axial and rotational movement, and a pusher member having a linear axis of travel including a first bore connected to a second bore. The first bore has a diameter that is less than a diameter of the second bore such that the first bore and the second bore include a stop. The rod portion has mechanical properties optimized to both conform to a needle curvature and provide sufficient compressive strength to expel the implants from the device.

Depth penetration limiters for tissue repair devices are disclosed. Depth penetration limiters for use with meniscal repair devices having a built-in self-stopping feature to prevent the limiter from dislodging from the device housing. The self-stopping feature is a cantilevered flexure on the bottom surface of the limiter that flexes as it moves through the housing. As the flexure passes the edge of a recess in the housing, the flexure returns to its original shape, thereby causing the flexure to catch on the recess and preventing further distal movement of the limiter / depth tube. A connection feature on the limiter provides increased pull-out resistance of the depth tube from the limiter.

A meniscal repair tool is described for use in arthroscopic knee surgery, designed to facilitate the repair of meniscal tears with improved precision and control. The tool features an ergonomic handle connected to an elongated shaft that extends into the knee joint. The distal end of the shaft includes a working end preloaded with sutures and anchors for securing meniscal tissue. A deployment mechanism allows for the controlled release of these sutures and anchors, while an integrated steering mechanism enables directional control of the working end. The steering mechanism, operable through dials or other controls on the handle, allows the working end to bend through a significant range, providing access to difficult -to-reach areas of the meniscus. Various embodiments include mechanical, electronic, or hydraulic actuators to enhance the flexibility and responsiveness of the steering mechanism, ensuring effective and minimally invasive meniscal repairs.
