Abstract: Methods treat a tissue region. In one arrangement, the methods deploy an endoscope in an esophagus and visualize with the endoscope a Z-line that marks a transition between esophageal tissue and stomach tissue by observing tissue color change at or near the Z-line. The methods deploy an electrode support structure over the endoscope at or near the Z-line visualized by the endoscope, wherein the endoscope serves as a guide for the electrode support structure. The methods introduce from the electrode support structure a tissue-piercing needle electrode into tissue at or near the Z-line and observe introduction of the tissue-piercing needle electrode using the endoscope. The methods couple the tissue-piercing electrode to a source of radio frequency energy to ohmically heat tissue and create a subsurface tissue lesion in tissue at or near the Z-line, and observe creation of the tissue lesion using the endoscope.

Abstract: A method for treating a sphincter provides a polymer material having a liquid state. The method also provides a catheter having a distal end, a tissue piercing device carried by the distal end, and an energy delivery device coupled to the tissue piercing device. The tissue piercing device has a lumen. The method introduces the catheter into an esophagus and pierces an exterior sphincter tissue surface within with the tissue piercing device. The method advances the tissue piercing device into an interior sphincter tissue site and conveys the polymer material while in a liquid state through the lumen into the interior sphincter tissue site. The method delivers energy to the tissue piercing device to transform the polymer material into a less liquid state within the interior sphincter tissue site, to thereby remodel the sphincter.

Abstract: Systems and methods for treating a tissue region employ an expandable structure projecting beyond the distal end of a catheter tube. A distal tail projects beyond the far end of the basket assembly. The distal tail includes a guidewire lumen that accommodates passage of a guidewire without threading the guidewire through the catheter tube.
