    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.

    Abstract: A medical device comprises an end effector, a mechanical structure, a connector, and a force sensor unit. The connector extends from a drive component of the mechanical structure to the end effector. Motion of the drive component produces a tension force within the connector, which is associated with an end effector torque or force exerted by the end effector. The force sensor unit comprises a body, and the body is coupled in-line with the connector so that strain in the connector is imparted to the body. A strain sensor measures the strain on the body as an indication of strain in the connector, which is an indication of torque or force at the end effector. The connector may be continuous, and coupled to the body with a slack relief portion of the connector within the body. Alternatively, the connector may be discontinuous and coupled to opposite ends of the body.
