摘要：
Numerous devices are described. One device may comprise: a handle (20) including a wire attachment portion； an actuator (30) movably mounted to the handle (20), the actuator (30) including a reaction chamber (39)； a plunger (40) movably mounted to the actuator (30), the plunger (40) including a distal stop (44D) with a sheath attachment (46) portion, and a proximal stop (44P) located in the reaction chamber (39)； a resilient element (80) including a distal end (80D) attached to the proximal stop (44P), and a proximal end movable relative to plunger (40)； and a force reduction element (90) located in the reaction chamber (39) between the resilient element (80) and a reaction surface in the cavity. The resilient element (80) may bias the plunger (40) distally relative to the actuator (30), and be compressed when a proximally-directed force is applied to the plunger (40). The force reduction element (90) may dissipate a portion of the proximally-directed force. Related devices and methods are also described.
