GE Thermometrics and GE NovaSensor, providers of miniature thermistors, silicon microstructures and sensors, and units of GE Industrial Systems and the General Electric Company have announced two multi-year agreements with Edwards Lifesciences Corporation.
The agreements, worth more than $50 million over the next five years, will provide thermistors and pressure sensors for use in the Swan-Ganz thermodilution catheter and disposable blood pressure transducers produced by Edwards Lifesciences.
Used extensively in cardiac diagnostic and corrective procedures, the disposable Swan-Ganz thermodilution catheter is inserted into a vein in the groin or neck of a patient and fed through the heart via the pulmonary artery. A glass sealed GE thermistor is located near the tip, where the time-temperature profile is measured by the thermistor. The resulting analysis yields the cardiac output or blood volume per minute.
GE will also provide its NPC-107 pressure sensor, specifically designed for use in disposable medical applications. The sensor integrates a pressure sensor die with temperature compensation circuitry and gel protection in a small package for use in disposable blood pressure transducers.
