Claims
- 1. A non-invasive cardiac device which may be inserted through the esophagus and into the gastroesophageal junction region and a selected portion urged adjacent the cardiac region for internal stimulation, pacing, and monitoring, comprising:
- an elongated conduit having a series of electrodes disposed thereon along its length so as to be adjacent the cardiac region when the device is in position in the esophagus;
- first locating means for positioning said electrodes adjacent the cardiac region and a distal end of said device adjacent said gastroesophageal region, said first locating means being joined to said conduit at the conduit distal end; and
- second locating means for positioning said device in said esophagus joined to the conduit and extending outwardly therefrom with at least some of said electrodes in abutting contact with the cardiac region.
- 2. A non-invasive cardiac device according to claim 1 wherein said first and second locating means each comprises expandable balloon-like members which selectively inflatable to position the device in the esophagus.
- 3. A non-invasive cardiac device according to claim 2 including third locating means, joined to the first and second locating means and operable from a position exterior said esophagus, for supplying said first and second locating means with a fluid.
- 4. A non-invasive cardiac device according to claim 1 including an external measurement device and means for electrically coupling said electrodes to the external measurement device.
- 5. A non-invasive cardiac device according to claim 1 wherein said electrodes are conductive, generally circular bands.
