Abstract
The invention relates to a sensor/guide wire device for biological pressure measurements having a guide wire (,) having a distal and a proximal end, and a pressure sensor device (,) mounted at the distal end of the guide wire. The distal portion can be a solid wire member (,) surrounded by a spiral member (,), and the sensor (,) can be an electrical sensor of a piezoresistive type. The sensor (,) is mounted on the solid wire (,). The sensor is mounted in a cantilevering fashion such that a pressure sensitive end of the sensor does not contact any structure other than its mount. This prevents forces (bending artifacts) from being exerted on the sensor, which could otherwise interfere with pressure measurements.
