Abstract
Actuating mechanism for rapidly and selectively moving a threaded screw and nut member combination into or out of threaded engagement, particularly for use of the screw as a control fluid plunger to pressurize angioplasty balloon catheters, or the like, which mechanism includes a housing and a threaded screw slideably displaceable through the housing, and a nut member having partial threads engageable and disengageable with the threaded screw structure. A carriage structure is secured to the nut structure and arranged to enable reversibly translating motion together with the nut member relative to the screw structure to enable the selectively threaded engageability of the partially threaded nut member with the screw structure.
