<P>PROBLEM TO BE SOLVED: To provide a fluid pressurizing device for a balloon catheter or the like, which particularly is the improved device for operating a screw plunger and monitoring the fluid pressure resulting therefrom. <P>SOLUTION: The fluid displacement device 200 is used for pressurizing the balloon catheter or the like. The device 200 includes the plunger displaceable through a housing 208, and an actuating mechanism for engaging with the plunger. The actuating mechanism includes a nut member biased into engagement with a threaded portion of the plunger. The device has a pressure-to-release function wherein the plunger is releaseable by simply depressing a control surface to overcome a restorative spring force. Subsequently, the plunger can be translated by macro movements (that is, by pushing/pulling the plunger). <P>COPYRIGHT: (C)2013,JPO&INPIT |
