  • Esophageal transducer
    Patent number: 3939823
    Abstract: An esophageal transducer measures pressure due to esophageal contractions. The transducer is inserted into the esophagus at the end of a catheter. The transducer is fully contained within a housing at the end of the catheter and is capable of measuring pressure variations at all points about its entire circumference. The housing has a flexible portion extending around its entire circumference which encloses a fluid-filled section. The fluid of the fluid-filled section contacts a pressure-sensitive piezoelectric material which produces an electrical output indicative of pressure changes in the fluid-filled section.
