A device for snaring cord-like objects is provided. The device comprises a hollow shaft having a pointed distal end, a rod having a pair of wires attached to its distal end, the wires being spring biased away from one another, and housing. The rod and wires are located in the lumen of the shaft in reciprocally movable relationship with each other. The housing is attached to the proximal ends of the shaft and the rod so as to allow controlled movement of the rod and wires relative to the shaft. One of the wire-like elements defines a hook-shaped configuration at its distal end. The device allows the wire-like elements to be selectively located within the distal end of the shaft or in a configuration where the wire-like elements extend outwardly from the distal end of the shaft in flaring relationship to one another. |
