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.

Claims

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.

2. An esophageal catheter as in claim 1 with said plurality of electrodes and said temperature sensor carried on a flexible planar member with said planar member removably affixed to said body.

3. An esophageal catheter as in claim 2 with said planar member carrying a layer of adhesive wherein said adhesive layer removably affixes said member to said body member.

4. An esophageal catheter as in claim 1 with said plurality of electrodes and said temperature sensor carried on a flexible, plastic, planar member with a layer of adhesive carried thereon, said planar member being removably affixed to said body member by said layer of adhesive.

5. An esophageal catheter as in claim 1 with said electrodes carried on a flexible sheet member removably carried on said body member.

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.

7. An esophageal probe comprising:

an elongated body having a proximal end and a distal end;

an imaging transmitter/receiver carried on said distal end;

a plurality of spaced-apart electrodes usable for esophageal pacing affixed to said body between said proximal end and said transmitter/receiver with at least some of said electrodes located about 10 centimeters from said transmitter/receiver;

a temperature sensor removably located on said distal end near at least some members of said plurality; and

means for electrically coupling to and selecting at least some of said electrodes.

8. 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 distal end, said distal end insertable into the esophagus of the individual;

a cardiac imaging transducer carried at said distal end;

a plurality of spaced apart conductive members carried on said body member, displaced from said transducer toward said proximal end with each of said members electrically coupled to said proximal end, said transducer usable for carrying out a cardiac imaging function in combination with a cardiac stimulating function using at least a selected one of said conductive members; and

a temperature sensor removably carried on said body member, adjacent to said distal end for monitoring a temperature of the individual.

9. An esophageal catheter as in claim 8 with said plurality of conductive members removably affixed to said body member.

10. An esophageal catheter as in claim 8 with said plurality of members and said temperature sensor carried on a flexible planar member with said planar member removably affixed to said body member.

11. An esophageal catheter as in claim 10 with said planar member carrying a layer of adhesive removably affixing said member to said body member.

12. An esophageal catheter as in claim 8 with said plurality of members and said temperature sensor carried on a flexible planar member with adhesive carried on said planar member, said planar member being removably affixed to said body member by said adhesive.
