Abstract
A retrieval device includes a sheath having a distal end, and a plurality of support members extending distal of the distal end, the support members each including a distal loop. The retrieval device further includes a hollow member extending distal of the distal end, and a movable member extending distally from the hollow member and slidably extending through the distal loops of the support members.
Claims19
A retrieval device, comprising:
- a sheath having a distal end and a longitudinal axis;
- a plurality of support members extending distal of the distal end, the support members each having at least one distal loop, wherein at least one of the distal loops of the support members forms at least one biasing coil;
- a hollow member extending distal of the distal end;
- and
- a movable member extending distally from the hollow member and slidably extending through the distal loops of the support members,
- wherein a first plurality of the support members are longitudinally movable relative to the sheath, and wherein a second plurality of the support members are longitudinally fixed relative to the sheath.
