Esophageal stethoscope
First Claim
1. An esophageal stethoscope comprising a tubular flexible body having a proximal end and a closed distal end, an acoustic input region defined on said body and spaced from said closed distal end, first and second spaced apart electrodes mounted on said body and between said distal end and said acoustic input region, said electrodes being spaced from each other and the acoustic input region, the distance between the mid-point of the space between said electrodes and said acoustic input region being about 5-10 cm.

Abstract
An esophageal stethoscope comprises a tubular flexible body having a proximal end and a closed distal end, an acoustic region defined on the body and spaced from the closed distal end. First and second spaced apart electrodes are mounted on one side of the body and between the distal end and the acoustic input region. The electrodes are spaced from each other and the distance between the mid-point of the electrodes and the acoustic input region is about 5-10 cm. A second pair of electrodes are mounted between the distal end and the first electrode pair and are manually movable laterally into engagement with the esophageal tissue.
