  • Publication number: 20210177435
    Abstract: In one embodiment, a cutting guide is disclosed for use in a surgical procedure to removed damaged tissue from a patient and form a recipient site configured and dimensioned to receive a donor graft. The cutting guide includes a first aim that abuts a section of the damaged tissue to be removed, and a second arm including a hole and a slot that receives a cutting implement, the first arm and the slot defining a distance therebetween corresponding to a desired dimension of the recipient site. In another embodiment, a cutting guide is disclosed for use in forming a donor graft from donor tissue. The cutting guide includes a body that receives the donor tissue, and a shaping member that is rotatably secured to the body. The shaping member includes at least one vane that shapes the donor tissue so as to form the donor graft.

  • Publication number: 20190059911
    Abstract: Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.

  • Publication number: 20170172585
    Abstract: Systems, apparatus, and methods for forming a non-circular tissue graft from donor tissue, and a corresponding recipient site in patient's tissue, are disclosed. In one embodiment, a cutting guide is disclosed for use in forming the recipient site. The cutting guide comprises a deformable body including a non-circular window, through which the patient's tissue is accessed, that is reconfigurable to contour to the patient's tissue. A cutting bit is also disclosed for use with the cutting guide in forming the recipient site. The cutting bit engages and follow a cutting route defined by the cutting guide, and includes a shaft, as well as a cutting head that removes portions of the patient's tissue. A cutting guide for use in forming the tissue graft from the donor tissue is also disclosed, which includes a removable template defining a channel that corresponds in configuration and dimensions to the cutting route.

  • Publication number: 20160074151
    Abstract: A graft-positioning system that includes a body further comprising a shaft, a handle engaged to the first end of the shaft, a guide rest engaged to the second end of the shaft and a flange engaged to the guide. In addition, the shaft also includes a plurality of pin channels that extend from the first end to the second end of the shaft. The graft-positioning system may also include plurality of guide pins that are configured and arranged to be received within the plurality of pin channels. Additional embodiments provide an arthroscopic cutter that includes a tubular body and a drive shaft attached to a cutting head at one end and situated within a lumen defined within the tubular body. The tubular body further includes a guide rest engaged to the distal end of the tubular body and a flange engaged to the guide rest.
