ABSTRACT:
A medical device has a body, an actuating member mounted to move relative to the body, a working element, and an elongated force-transmitting member capable of transmitting actuating force between the actuating member and the working element. The force-transmitting member includes a flexible cable portion, the force-transmitting member is attached, on one side of the cable portion, to the body and associated in a driving relationship on the opposite side of the cable portion with the working element. According to the invention the actuating member includes a pulley surface bodily movable therewith, the cable portion is trained about the pulley surface such that movement of the actuating member a given distance, relative to the body, causes the working element to move a substantially greater distance than the given distance. Another aspect of the invention is a medical snare with the above features.
