A medical grasping device has an elongate control member with a grasping member proximal to its distal tip. An outer sheath with a passageway therethrough surrounds the elongate control member and is relatively movable with respect to the control member. A control assembly disposed at a proximal end of said outer sheath has a fixed handle and a sliding handle and the proximal end of the elongate control member is fixed to the sliding handle to move the control member. The grasping member has a plurality of pre-formed wire loops which self-deploy transversely upon emerging from said distal end of said outer sheath. Each wire loop is fastened to substantially opposite sides of the elongate control member so that each of said wire loops is substantially semi-circular upon full deployment and the respective ends of each wire loop extend substantially in opposite directions from the elongate control member.
