Abstract:
A device for selectively capturing, cutting and retrieving tissue, comprising:A) a handle having an elongated, flexible tube extending therefrom along a central axis to a distal end; B) a first set of elongated, flexible wires slidingly positioned within the tube and extending along the central axis from the handle to joined distal ends for extending out of the distal end of the tube; C) a second set of elongated, flexible wires slidingly positioned within the tube and extending along the central axis from the handle to joined distal ends for extending out of the distal end of the tube; and D) a control tip joining the distal ends of the first set of wires and including a transverse portion extending beyond the distal end of the tube in a direction transverse to the central axis, the transverse portion being adapted for interfering engagement with the distal end of said tube, thereby preventing the distal ends of said first set of wires from being wholly drawn into said tube, and wherein the wires of said first set and said control tip are formed from a single wire, said control tip having a substantially S shape defining two apertures separated by a retaining pin portion, and wherein the wires of said second set pass on opposite sides of said retaining pin portion and through an associated one of said apertures; and wherein said retaining pin portion is adapted for interfering engagement of the joined distal ends of said second set of wires, thereby maintaining said distal ends of said second set of wires farther from said distal end of said tube than said control tip.
