Claims7
An esophageal probe, comprising:
- a shaft assembly comprising an elongated shaft having a distal end, a proximal end, an inflation lumen extending along the shaft, and an inflatable balloon on the shaft communicating with the inflation lumen;
- and
- at least one conductive electrode on an outer surface of said balloon, said shaft assembly including a first connector adjacent the proximal end of the shaft, and including a second connector releasably attached to the first connector, means for establishing electrical connection between the attached first and second connectors, and conductive means connecting said electrode to the electrical establishing means, said inflation lumen extending through the first connector and into said second connector, and said shaft assembly having valve means in the second connector communicating with the inflation lumen to inflate and deflate the balloon.
An esophageal probe, comprising:
- a shaft assembly comprising an elongated shaft having a distal end, a proximal end, an inflation lumen extending through the shaft and communicating with an opening adjacent the distal end of the shaft, and an inflatable balloon adjacent the distal end of the shaft, said balloon comprising a cylindrical sleeve of elastic material having opposed ends bonded to the shaft in circumferential zones, said sleeve defining a cavity communicating with said opening;
- and
- a pair of annular spaced conductive electrodes adjacent opposed ends of the sleeve on an outer surface of the sleeve, said electrodes extending completely circumferentially around the sleeve in circumferential zones, and a pair of conductive leads connected to said electrodes.
