Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
An esophageal probe for use in diagnosis or as a stimulant comprising: a flexible elongated conduit having a proximal end and a distal end; a first EKG electrode positioned on said conduit near said distal end; a first ultrasonic transducer longitudinally positioned on said conduit in selective spaced relationship to said first electrode; a second ultrasonic transducer longitudinally positioned on said conduit in selective spaced relationship to said first transducer; a second EKG electrode positioned on said conduit in selective spaced relationship to said second ultrasonic transducer and spaced at a distance from the proximal end; the ultrasonic transducers being positioned between the EKG electrodes, conductive pathways connected to said electrodes and transducers; said proximal end being adapted for receiving the conductive pathways from each of the electrodes and transducers for connection with electrocardiological and echocardiographic devices; and wherein the selective spaced relationship between each electrode and transducer is equal and not more than 5 centimeters.
Claim 2
Dependent Claim
156 words
