Sensor jacket

Abstract

A sensor guide wire for intravascular measurement of a physiological variable includes: a core wire extending at least partly along a length of the sensor guide wire; a sensor element in a sensor region of the sensor guide wire; a jacket having a jacket wall, the jacket being fixed relative to the core wire; and at least one lead connected to the sensor element. The jacket is tubular and includes a proximal end opening, a distal end opening, and a first set of openings extending through the jacket wall. The first set of openings extending through the jacket wall includes a first opening located above the sensor element, a second opening located at a first lateral side of the sensor element, and a third opening located at a second lateral side of the sensor element, and wherein the first, second, and third openings are elongated in a longitudinal direction of the jacket, and are aligned in a circumferential direction of the jacket.
