Anatomical location markers and methods of use in positioning sheet-like materials during surgery

An implant positioning and delivery kit comprising:

• a tissue marker assembly including a delivery sleeve with a tissue marker slidably disposed within a lumen therethrough and a proximal handle coupled to the delivery sleeve;
• a guidewire including a distal portion having a tissue fixation member for releasably coupling the guidewire to bone and a proximally extending wire portion;
• and,
• an implant delivery system for delivering a sheet-like implant having a delivery shaft with a proximal end and a distal end defining a generally longitudinal direction and including a guidewire port proximate the distal end of the delivery shaft for slidably receiving the guidewire therein to track the proximal wire portion to a delivery site when the guidewire is coupled to bone or other tissue.

A method of marking the location of a biceps tendon relative to a supraspinatus tendon on the bursal side of the supraspinatus tendon for accurately positioning a sheet-like implant over at least a portion of the bursal side of the supraspinatus tendon during arthroscopic surgery, the method of marking comprising the steps of:

• observing the location of the biceps tendon relative to the supraspinatus tendon on the articular side of the supraspinatus tendon;
• providing a tissue marker including an elongate shaft defining a longitudinal direction;
• and,
• inserting the tissue marker through the supraspinatus tendon so that a distal end emerges on the articular side adjacent the posterior side of the biceps tendon.
