The present invention provides a snare for intravascular use having an elongate proximal member and a loop-shaped distal segment oriented at an angle to the adjacent portion of the proximal member. The snare may be formed of a superelastic shape memory alloy, which permits the distal segment to be collapsed for passage through a catheter and yet automatically open into its original, unrestrained configuration upon emerging from the distal tip of the catheter.
