RETRIEVAL DEVICES AND RELATED METHODS OF USE |
摘要 |
<p>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.</p> |
