Connector for interfacing intravascular sensors to a physiology monitor

[0038]In general, an exemplary signal conditioning device embodying the present invention, described herein below with respect to FIG. 2, is designed to interface a guide wire-mounted pressure sensor to a standard physiology (e.g., blood pressure) monitor. The signal conditioning device processes a signal received from the guide wire-mounted pressure sensor and presents a normalized signal to any of multiple different physiology monitors having potentially differing signal requirements.

[0039]From the point of view of overall system setup, the exemplary signal conditioning device reduces the number of power sources, as well as the distinct cables and physically distinct apparatuses, required to conduct intravascular blood pressure measurements. These desirable attributes are achieved by having the conditioning device receive and / or utilize a differential sensor excitation signal, transmitted by known physiology monitors in a novel manner.
