Abstract:
A method of fabricating a sensing catheter assembly, comprising:forming a catheter body having a circumferential wall and defining first and second lumens, placing first and second electrical leads in the second lumen by co-extruding the first and second electrical leads and the catheter body; forming an opening in the circumferential wall to expose the first and second electrical leads; providing a microminiature sensor module comprising a substrate, a microminiature sensor disposed on the substrate, a signal conditioning circuit disposed on the substrate and in electrical communication with the sensor, and first and second electrical contacts in electrical communication with the sensor and circuit; disposing the sensor module in the opening and adjacent the first and second electrical leads; placing the first and second electrical contacts in electrical communication with the first and second electrical leads; and sealing the opening.
