Abstract
A medical guidewire system for guiding thereon a medical implement includes an end effector, an actuation guidewire having a distal end permanently connected to the end effector, and a control assembly. The assembly has a handle, a shaft receiving the guidewire. The shaft has a proximal end permanently connected to the handle and a distal end temporarily connected to the end effector. A first actuator is movably connected to the handle and operatively connected to the guidewire to actuate the end effector. A second actuator is movably connected to the handle and operatively connected to a portion of the guidewire to disconnect the guidewire from the handle when actuated and, thereby, permit removal of the control assembly from the end effector and guidewire. When the control assembly is removed, the end effector and the guidewire form a surgical exchange or guidewire for guiding thereon the medical implement.
