Abstract:
1. A method of accurately positioning a sheet-like implant over a treatment site during arthroscopic surgery comprising the steps of: observing and measuring the treatment site to determine a preferred location for the sheet-like implant to be delivered; identifying a guidewire attachment point proximate the treatment site that is a known lateral and longitudinal distance from the preferred location for the sheet-like implant to be delivered; fixing a distal end of a guidewire at the guidewire attachment point, tracking an implant delivery system over a proximal portion of the guidewire to a position adjacent the guidewire attachment point, the implant delivery system having the sheet-like implant releasably coupled proximate a distal end thereof and a distal guidewire port disposed the known lateral and longitudinal distance relative to the sheet-like implant; and, deploying the positioned sheet-like implant, and wherein the implant delivery system further including a delivery shaft having a proximal end and a distal end defining a generally longitudinal direction; an implant retainer assembly proximate the distal end of the delivery shaft configured to releasably couple the sheet-like implant thereto for positioning the sheet-like implant at the treatment site, and wherein the implant retainer assembly comprises a center post disposed proximate the distal end of the delivery shaft and a mating surface spaced from the center post, wherein the mating surface cooperates with the center post to retain the sheet-like implant therebetween.
