Abstract

A graft preparation system includes a fixation implant including a strand of suture wrapped around a graft preparation card. A tenaculum includes a first arm having a first tooth and a second arm having a second tooth that are pivotally connected at a pivot. The first arm includes a slot between the first tooth and the pivot that receives the graft preparation card. A tape suture assembly includes a tape suture and a first suture strand. The tape suture is positioned on a graft, and the tape suture is attached to the graft with a stitch formed with the first suture strand.

Core Innovation

A graft preparation system integrates a graft preparation card having a longitudinal axis with a suture strand wrapped around the graft preparation card and a button including a button hole. The suture strand passes through the button hole of the button, so the button is used to direct the suture strand with respect to the graft preparation card. The system further incorporates a fixation implant configured to work with the adjustable suture construct and an adjustable loop.

The graft preparation system includes a graft preparation card with a defined passage and a keyhole shaped opening having a curved portion, as well as first and second holes on the card. The card further includes first and second slits and grooves and cleats arranged for routing and sliding parts of the suture construct, including first adjustable eyesplice and second adjustable eyesplice. A loop is positioned and guided relative to holes on a front side of the graft preparation card.

The system additionally uses a tenaculum with pivotally connected arms and teeth that pierce a tape suture and graft. A tape suture assembly is described in which a tape suture has a first suture strand and a second suture strand and is attached to a graft using stitches. Fixation implant sutures pass through the tape and graft to secure the adjustable loop, including an adjustable loop length.

Claims Coverage

The provided independent claims cover a graft preparation system using a graft preparation card, a suture strand wrapped around the card, and a button with a button hole through which the suture strand passes; and a graft preparation card that includes third, fourth, and fifth holes. Across these independent claims, the main inventive features focus on the card-based suture and button interface and the presence and geometric location/alignment of multiple holes on the card.

As recited, the claim coverage centers on a graft preparation card and a buttonhole-controlled suture strand path, together with a card geometry that includes multiple holes, including third, fourth, and fifth holes.
