  • Ultrasonic transesophageal probe with articulation control for the imaging and diagnosis of multiple scan planes
    Patent number: 5479930
    Abstract: A multiplane TEE probe is provided for the imaging and diagnosis of multiple scan planes from within a cavity of the body. The probe includes an articulation section formed of a plurality of interconnected links. The articulation section is controlled from the handle of the probe, with the articulation limit stops located in the handle. The articulation section may be locked in a given bent position, but the lock will be overcome by the force of the esophagus against the transducer tip if the probe is withdrawn in a locked and bent position. When the articulation section is locked an indication signal is displayed on the handle of the probe and on the display of the ultrasound system.
