Abstract
An electrical lead having an elongated flexible lead body having a flattened cross sectional configuration. One flattened surface is provided with at least one aperture open to a longitudinal lumen carrying an electrode lead. The electrode lead is provided with electrodes located within the aperture, and the electrode lead is slideable within the lead body to allow for adjustment of the position of the electrodes within the aperture. The lead body is also provided with at least one expansible balloon, located radially opposite the aperture. In use, the lead is advanced down the esophagus, with the surface of the lead bearing the aperture facing anteriorly. Inflation of the balloon urges the aperture and the electrodes located therein adjacent the anterior surface of the esophagus. After inflation of the balloon, the electrode lead may be moved within the lead body to allow for adjacent of electrode location.
