  • Inflation device for dilatation catheters
    Patent number: 5342304
    Abstract: An apparatus for inflating and deflating a balloon on a dilatation catheter in order to perform an angioplasty procedure therewith. The inflation/deflation apparatus has an elongated housing with a piston disposed within a bore within the housing and a threaded piston rod connected to the piston. A threaded split collar or nut is disposed about and engaged with the threaded piston which allows the piston rod to be rotated about its axis in order to move the piston longitudinally in small increments within the bore of the housing. Flexible arms are connected to each half of the split collar or nut which when moved away from the piston rod, disengage the split collar or nut from the piston rod and allow longitudinal movement of the piston within the bore by pushing on the piston rod.
