ABSTRACT:
A surgical instrument and method for facilitating the capture of objects during surgery are provided. The surgical instrument includes a flexible tube defining a cable passageway and being configured for insertion of at least portion of the flexible tube into a body cavity of a patient. The surgical instrument further includes flexible cable slidably disposed in the cable passageway. A snare loop is attached to the cable end and both are adapted so that the snare loop can be selectively retracted or extended within the cable passageway by sliding the cable proximally or distally within the cable passageway. The loop member is adapted for selectively encircling and engaging at least a portion of an object in the body cavity. The system also comprises a tether, the tether attached to the loop member at one end and to the flexible tube at the other, so that extension of the flexible cable causes the snare loop to deform in a predetermined manner.
