Abstract
A surgical snare instrument includes an elongated tubular sheath having proximal and distal ends, a flexible torqueable shaft having proximal and distal ends extending through and axially movable relative to the sheath, a snare loop at the distal end of the shaft, and a handle coupled to the proximal ends of the sheath and shaft for moving the shaft relative to the sheath and for rotating the shaft relative to the sheath so that the snare loop, when extended beyond the distal end of the sheath, is rotatable relative to the distal end of the sheath. The shaft is preferably a multifilament twisted and drawn cable. The filaments of the multifilament twisted and drawn cable are preferably either stainless steel, nickel-titanium alloy, or a combination of the two. Such a shaft has been demonstrated to provide the high torqueability necessary for controlled rotation of the snare loop.
