Abstract: Embodiments of the invention include instruments and methods useful in preparing and delivering graft material to a surgical site. Some embodiments may particularly be directed to forming a graft from a blood clot and accurately and effectively handling and delivering the graft to a surgical site. Graft material may include blood components such as clotted fibrin derived from a patient's or a donor's blood.

Abstract: A graft caliper provides for a first member having a first pick at its distal end and its proximal end attached to a handle. A second member of the graft caliper is disposed above the first member and has a second pick at its distal end that extends beyond the first pick. The proximal end of the second member is attached to an adjuster which causes the second member to move from a first position to a second position in order to change a distance the second pick extends beyond the first pick. The graft caliper provides for an indication of at least one metric for describing the distance the second pick extends beyond the first pick and places an identifier on a surface of bone representing the location of a tunnel to be formed through a femur, tibia or any other anatomical structure.

Abstract: A sheath for organizing soft tissue includes a first tube having a flexible body sized and shaped to receive a fixation device, and a second tube coupled to the first tube having a flexible body sized and shaped to receive a soft tissue graft. A method for implanting soft tissue in a bone tunnel includes coupling a soft tissue graft to a sheath assembly; and positioning the sheath assembly relative to the soft tissue graft based on a measured depth of a bone tunnel. A set of surgical devices for implanting soft tissue grafts in a bone tunnel includes a sheath assembly, a measurement device for measuring the depth of the bone tunnel, a securing element configured to secure the sheath assembly to the soft tissue graft at a position determined by the measured bone tunnel depth, and a tensioning device configured to organize a plurality of soft tissue grafts.

Abstract: A medical device that attaches to tissue without requiring stitching includes a tissue fixation device having a first sub-loop and a second sub-loop, and an assisting member disposed through the first sub-loop and through the second sub-loop. The tissue fixation device includes an adjustable, flexible member formed by inserting one end portion of the flexible member through another end portion of the flexible member, and first and second sub-loops formed by crossing a portion of the flexible member over a different portion of the flexible member.

Abstract: A graft anchor includes an anchor member for placement in bone tissue. The anchor member defines an opening. An inner member is insertably securable into the anchor member opening. A fastener is configured such that insertion and securing of the inner member into the anchor member opening results in a holding force being applied to the graft. The anchor member is of limited length to maintain its distal end within the bone. The anchor member includes a distal drive opening for receiving a drive tool and the inner member includes a proximal drive opening for receiving the drive tool. The fastener includes channels for containing the graft, a fastener body with protrusions extending from the fastener body for penetrating bone tissue, and a reinforcing member contained within the fastener body.

Abstract: A graft clamp for securing a tissue graft located within a tunnel in bone includes a first member having a first clamping face, and a second member having a second clamping face. The first and second members are sized for positioning at an opening of the tunnel such that the first and second clamping faces are positioned substantially transversely to a bone surface defining the tunnel opening to secure the tissue graft therebetween. The clamping faces have ridges. The first member includes a spike for insertion into the bone, and a collar for insertion into the opening of the tunnel. An attaching element, for example, a screw, attaches the second member to the first member. The clamping faces are located exterior to the tunnel with the attaching element extending into the tunnel. The position of the first member and the second member at the tunnel opening is maintained at least partially by tension applied to the tissue graft.
