Dorros-Spring pressurizer: an inflation device for use in transluminal angioplasty procedures.
A simple hand-operated balloon inflation device has been developed for use in coronary and peripheral transluminal angioplasty procedures. This device is compact, portable, and easily sterilized and eliminates the need for compressed gas, pneumatic pistons, carbon dioxide cartridges, or a complex holder or mounting apparatus. This device, the Dorros-Spring pressurizer, provides for precise control of pressures which inflate the angioplasty dilatation catheters by means of an hydraulic saline-contrast system. This inflation device has been used in over 150 coronary and 100 peripheral transluminal angioplasties without the occurrence of failure of mechanical components or loss of calibration.
