1. A sensor guide wire device comprising:
- a sensor guide wire configured to perform an intravascular measurement of a physiological variable in a living body, the sensor guide wire comprising at least one sensor element configured to sense the physiological variable in the living body; and
a connector unit configured to be directly or indirectly connected to a proximal end of the sensor guide wire, the connector unit being physically attachable to a signal converter via electrical contacts, the connector unit being configured to provide the signal converter with a signal indicative of the physiological variable sensed by the sensor element, the signal converter being configured to convert the signal received from the connector unit into a processed signal that is receivable by a physiology monitor,wherein the connector unit comprises a housing and a power supply disposed in the housing, the housing of the connector unit being separate from a housing of the signal converter,wherein the housing of the connector unit is reversibly attachable to and detachable from the housing of the signal converter,wherein the connector unit is configured such that, when the housing of the connector unit is attached to the housing of the signal converter, a surface of the housing of the connector unit abuts a surface of the housing of the signal converter, and the power supply of the connector unit powers the signal converter via the electrical contacts, andwherein the sensor guide wire and the connector unit are disposable.

Abstract
A sensor guide wire device (200) for intravascular measurements of a physiological variable in a living body is disclosed. The sensor guide wire (200) may comprise a sensor element (213) and a connector unit (220). The connector unit (220) is attachable to a signal converting device (310). The sensor element (213) provides the signal converting device (310) with a signal indicative of a physiological variable sensed by the sensor element (213). Furthermore, the connector unit (220) comprises a battery (222). A system (300) comprising the sensor guide wire device (200) and the signal converting device (310) is also disclosed.
