Abstract

Electrosurgical tissue specimen recovery apparatus and system employing a multi-leaf capture component configured with pursing cables which are electrosurgically excited to define a cutting leading edge. To complete a capture, the cables are loaded in tension to purse and thus converge the tips of the capture component leafs together. The forward regions of the leafs are configured with a combination of a thin flat stainless steel region over which a polymeric cable guide is positioned. The polymeric cable guide and stainless steel leaf driving combination improves frictional aspects as well as the resulting aspect ratio of a recovered tissue specimen.
