To provide a collapsible medical device which can easily be deployed and retracted during a minimally invasive medical procedure.
The medical device has a distal end and a stop spaced proximally of the distal end. A proximal length of a mandrel extends proximally of the stop, and a distal length of the mandrel extends distally of the stop. An operation member has a radially expandable body, and has a proximal slider and a distal slider. The proximal slider and the distal slider are slidable along the mandrel independently of one another so that a different configurations of the operation member can be effected by the variation of the distance between the proximal slider and the distal slider. By urging the mandrel distally, the operation member is urged to a treatment site. Thus, the stop exerts a distal biasing force on the distal slider, acts against a restorage force of the operation member to axially elongate the operation member, and reduces the friction between the operation member and the wall wall of the vessel.
