Abstract
According to an embodiment of the present disclosure, a retrieval device may include a distally located end effector movable between a contracted state and an expanded state. The end effector may include a plurality of support members each including a passage. The end effector may also include a plurality of movable members. A first movable member may include a first portion extending into a first passage of the support member passages. The retrieval device may also include a proximally located handle assembly including a longitudinal actuator and a twisting actuator coupled to the plurality of movable members. The longitudinal actuator and twisting actuator may be configured to longitudinally move and twist the movable members without longitudinally moving and twisting the support members.
Claims18
A handle assembly comprising:
- a housing coupled to an outer sheath including a lumen;
- and
- an actuation assembly that is coupled to a drive member extending through the lumen, movably mounted to the handle assembly, and movable to translate and rotate the drive member independent of the outer sheath,
- wherein a distal end of the outer sheath is coupled to a plurality of support members, and wherein each support member has a passage,
- wherein a distal end of the drive member is coupled to a plurality of movable members, and wherein each movable member extends through one of the passages, and
- wherein the drive member is rotatable relative to the plurality of support members to generate a torsion in the plurality of moveable members.
A handle assembly comprising:
- a housing coupled to an outer sheath including a lumen and a plurality of support members;
- and
- an actuation assembly that is movably mounted to the housing and coupled to a drive member extending through the lumen, the drive member including a plurality of moveable members extending through the plurality of support members, the actuation assembly being movable to translate and rotate the plurality of moveable members independent of the plurality of support members,
- wherein a distal end of the outer sheath is coupled to the plurality of support members, and wherein each support member has a passage,
- wherein each movable member extends through one of the passages of the plurality of support members, and
- wherein the drive member is rotatable relative to the plurality of support members to generate a torsion in the plurality of moveable members.
A handle assembly comprising:
- a housing coupled to an outer sheath including a lumen;
- and
- an actuation assembly that is coupled to a drive member extending through the lumen, movably mounted to the handle assembly, and includes:
- (i) a longitudinal actuator movable to translate the drive member independent of the outer sheath, and
- (ii) a rotational actuator movable to rotate the drive member independent of the outer sheath,
- wherein a distal end of the outer sheath is coupled to a plurality of support members, and wherein each support member has a passage,
- wherein a distal end of the drive member is coupled to a plurality of movable members, and wherein each movable member extends through one of the passages, and
- wherein the drive member is rotatable relative to the plurality of support members to generate a torsion in the plurality of moveable members.
