Abstract
An esophageal probe comprising, an elongated hollow sleeve defining a cavity. The probe has a first vibration detection device at a first distal location in the sleeve cavity, and a second vibration detection device in the sleeve cavity, with the second detection device being spaced a substantial distance proximally from the first detection device.
Claims7
An esophageal probe, comprising:
- an elongated hollow sleeve;
- first electrical means for detecting sounds at a first distal location in the sleeve, and a conductive lead connected to the first detecting means;
- and
- second electrical means for separately detecting sounds at a second location in the sleeve proximal said first location, and a conductive lead connected to the second detecting means.
