Zusammenfassung:	An inline flow control device for passive irrigation tubing to be used with electrophysiology devices, includes an elastically deformable diaphragm that can assume a neutral configuration, a first flexed configuration and a second flexed configuration in response to pressure change upstream or downstream of the diaphragm in self-adjusting the fluid flow to normalize the pressure change. In one embodiment, the diaphragm is unaffixed at least at its peripheral edge to allow the diaphragm to flex at its peripheral edge to vary the fluid flow through the device. In another embodiment, the diaphragm is fixed at its peripheral edge to allow the diaphragm to flex in its inner region to allow different movement of a piston through which the fluid flows in response to pressure changes upstream and downstream of the diaphragm.
