Patent ID: 8273016

Claim:
An esophagus isolation catheter adapted for use within a patient's esophagus, the esophagus isolation catheter comprising: an elongated catheter body having an axis, and at least one lumen therethrough; a deflectable section distal the catheter body and comprising a single elongated tubing; an elongated tip section distal the deflectable section and extending generally along the axis of the catheter body; and means for deflecting a region of the patient's esophagus about the deflectable section comprising a puller wire having a distal end anchored near a center of the elongated tip section and distanced from a distal end of the elongated tip section, wherein a length of the elongated tip section is such that longitudinal movement of the puller wire relative to the catheter body results in deflection of the deflectable section to form a generally C-shaped curve having an outer wall that displaces the region of the esophagus to be deflected while the elongated tip section extends undeflected in the esophagus without displacing a region of the esophagus distal the deflectable section before, during and after deflection.
