Abstract: An effector includes a tubular body having a proximal end and a distal end. The effector includes a plug or closure at the distal end of the tubular body; an active electrode at the distal end of the body; an insulator on the body; and one or more return electrodes on the insulator. The body dissipates heat generated by the one or more return electrodes from the distal end of the body to the proximal end of the body.

Abstract: A method of withdrawing an endoscope from anatomy comprises inserting the endoscope into the anatomy to deliver a distal end of the endoscope to a location, positioning a guide sheath around a proximal end of the endoscope, sliding the guide sheath along the endoscope to reach the distal end and withdrawing the endoscope from the guide sheath and anatomy. A system for intraoperatively attaching a suturing device to an in-situ endoscope comprises an insertion sheath comprising an elongate tunnel body extending between proximal and distal ends and a slit extending axially along the elongate tunnel body, and a suturing device couplable in a releasable manner to an endoscope. A reinsertion sheath for an endoscope comprises an elongate body comprising proximal and distal ends and a skin extending axially between the proximal and distal ends, and a slit extending along the shaft to allow circumferential expansion of the elongate body.

Abstract: A surgical instrument comprises an elongate body comprising a proximal end portion and a distal end portion and a tissue separator coupled to the distal end portion that is configured to engage sample tissue for collection, wherein the tissue separator is at least partially made from a material that allows light to pass through the tissue separator. A method of collecting biological matter using a tissue retrieval device comprises inserting the tissue retrieval device into anatomy of a patient, guiding a tissue collector of the tissue retrieval device to a target tissue, viewing the target tissue through the tissue collector and collecting biological matter from the target tissue with the tissue retrieval device.
