Abstract
A tissue marker assembly which can be useful with an implant delivery system for delivering a sheet-like implant is disclosed. The tissue marker assembly can include a delivery sleeve with a tissue marker slidably disposed within a lumen therethrough. A proximal handle can be coupled to the tissue marker and delivery sleeve, having a first part and a second part. The second part of the proximal handle can be releasably attached to the tissue marker proximal end so that the second part can be removed to allow the delivery sleeve to be removed proximally over the tissue marker after it is affixed to tissue. The distal portion of the marker can include a plurality of longitudinally extending arms when unconstrained project outward from the shaft to retain the marker's position in tissue.
