A method of assembly of a sensor in a pressure guidewire, the method comprising:
- using a band and a shaft tube window in a sensor housing section of a shaft tube of the pressure guidewire to position an inner hypotube within the sensor housing section, the band being bonded to a pressure sensor communication means, and
- securing the sensor within a pressure guidewire to the sensor housing section by bonding the band to the sensor housing section using a sensor joining window.
A pressure guidewire comprising:
- a sensor housing;
- a sensor assembly embedded in the sensor housing and comprising a pressure sensor and an inner hypotube;
- and
- a shaft tube window though a shaft tube of the sensor housing giving access to the inner hypotube for welding, soldering or bonding the inner hypotube to the shaft tube.
