RETRIEVAL DEVICES AND RELATED METHODS OF USE

摘要

A retrieval device may include a sheath including a distal end and a proximal end, and an end effector at the distal end. At least a portion of the end effector may be movable relative to the sheath between extended and retracted states. The end effector may include a support member extending from the distal end of the sheath, and a movable member extending from the distal end of the support member. The device may include a handle assembly at the proximal end of the sheath, having an actuation member for transitioning the end effector between the extended and retracted states. The device may include a biasing member coupled to at least one of the actuation member and the sheath that may control a force, exerted by one of the movable members and the support member on the other, generated by relative movement between the movable and support members.

1. A device, comprising:
a sheath including a distal end and a proximal end; an end effector at the distal end of the sheath, at least a portion of the end effector being movable relative to the sheath between an extended state and a retracted state, the end effector including a support member extending from the distal end of the sheath, and a movable member extending from the distal end of the support member; a handle assembly at the proximal end of the sheath, the handle assembly including an actuation member for transitioning the end effector between the extended state and the retracted state; and a biasing member coupled to at least one of the actuation member and the sheath, the biasing member controlling a force exerted by one of the movable member and the support member on the other of the movable member and the support member, the force being generated by relative movement between the movable member and the support member.
