Abstract
The present document describes a pressure guidewire. It comprises a shaft tube having a proximal section and a sensor housing having a distal end, the proximal section and the sensor housing being the continuity of the same shaft tube. A fiber optic pressure sensor is embedded in the sensor housing and comprises an optical fiber extending within the sensor housing, the sensor adapted to measure a pressure of a fluid which is substantially applied in an axis collinear with the longitudinal axis of the guidewire. A marker band, to help in localizing the pressure guidewire in a patient's vessels, is embedded inside the sensor housing and fixed to the optical fiber for holding the pressure sensor inside the sensor housing.
