First Claim
Patent Images
1. A multi-function esophageal catheter usable to produce cardiac images of an individual from the individual'"'"'s esophagus comprising:
- an elongated body member having a proximal end and a distal end, said distal end insertable into the esophagus of the individual;
a cardiac imaging transceiver carried at said distal end;
a plurality of spaced apart electrodes carried on said body member, displaced from said transceiver toward said proximal end with each member of said plurality electrically coupled to said proximal end, said transceiver usable for carrying out a cardiac imaging function in combination with cardiac pacing using at least a selected one of said electrodes; and
a temperature sensor carried on said body member, a selected distance from said distal end for monitoring a temperature of the individual wherein said electrodes and said sensor are removably affixed to said body member.

Abstract
A single use disposable esophageal electrode structure is formed with a planar sheet body member. The body member carries a plurality of spaced-apart conductive electrode members. A temperature sensor can also be carried on the body member. A layer of adhesive on the body member can be used to affix it to an esophageal probe. A plurality of conducting members is coupled to the body member. Each of the conducting members is in turn coupled to a respective one of the electrodes. A free end of the conducting members carries an electrical connector for connection to other electrical units.

6. An esophageal pacing and imaging probe usable to pace the heart of a patient comprising:
-
an elongated body portion having a proximal end and a distal end; a heart imaging transmitter carried on said distal end; a plurality of spaced-apart electrodes carried on said body portion between said proximal end and said transmitter but spaced therefrom thereby providing for independent positioning of said transmitter and independent selection of a pacing electrode optimally positioned with respect to the patient'"'"'s heart; and a temperature monitor removably carried on said body portion adjacent to said plurality of electrodes.
