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

Capture devices

A medical device may include a shaft and an end-effector extending distally of the shaft. The end-effector may be expandable between a collapsed configuration and an expanded configuration. The end-effector may include a proximal nose and a distal body. The proximal nose may have a radial dimension smaller than a radial dimension of the distal body in the expanded configuration. The end-effector may include a plurality of legs and a transition point of each leg may be located between the nose and the distal body along a common plane normal to the shaft. The shaft may include proximal ends of the legs wrapped about one another.
