Abstract

An articulable medical device includes a link, a transfer member, a tool member, and a non-drive wire. The tool member has a base portion movably coupled to the transfer member, and a contact portion configured to engage a target tissue. The transfer member is rotatably coupled to the link to rotate with the tool member relative to the link from a first orientation to a second orientation. The non-drive wire has a first end portion coupled to an energy source, a second end portion coupled to the tool member contact portion, and a central portion between the first and second end portions that includes a transition portion disposed within a cavity defined within the base portion of the tool member, a distal portion of the link, or the transfer member, which has a compact first configuration in the first orientation and an expanded second configuration in the second orientation.
