Claim 17:
18. A method of operating a medical device to close a jaw assembly of the medical device, wherein the medical device comprises an elongate transmission guide, a transmission cable within the transmission guide, and an input assembly at the proximal end of the transmission cable, the input assembly having an input member coupled to the transmission cable, wherein the transmission cable is coupled to an input of the jaw assembly, wherein the jaw assembly is distal to the elongate transmission guide, the method comprising:
actuating the input member to apply tension to the transmission cable during a first part of an input stroke of the input assembly to close a first and second jaw of the jaw assembly from an open configuration until the first and second jaws reach a stop;
continuing to actuate the input member during a second part of the input stroke after the first and second jaws have reached the stop and stretching the transmission cable;
wherein the input stroke consists of a displacement of the input member, and further wherein the input member transitions from the first part of the input stroke to the second part of the input stroke when the input member is between 30% and 70% displaced; and
applying a first mechanical advantage to the first and second jaws during the first part of the input stroke and applying a second mechanical advantage to the first and second jaws that is greater than the first mechanical advantage during the second part of the input stroke.
