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: A method detects at a tissue site an electrical activity causing a transient relaxation of at least a portion of one of a sphincter, a lower esophageal sphincter, a stomach, a cardia or a fundus. The method treats the electrical activity at the tissue site by delivering electromagnetic energy to ablate at least a portion of one of the nerve, the gastric nerve, a nerve plexus, a myenteric nerve plexus, a ganglia, a nerve pathway or an electrically conductive pathway. The method conducts a cooling solution to the tissue site at a flow rate and adjusts the flow rate in response to sensed temperature conditions.

Abstract: Systems and methods manipulate a support structure to form a composite lesion in a tissue region at or near a sphincter. The support structure carries an array of electrodes attachable to a source of energy capable of heating tissue when transmitted by the electrodes. The systems and methods advance the electrodes to penetrate the tissue region and form, when the energy is transmitted, a first pattern of lesions. The systems and methods retract the electrodes, and shift the position of the electrodes, either rotationally, or axially, or both rotationally and axially. The systems and methods advance the electrodes a second time to form, when the energy is transmitted, a second pattern of lesions either rotationally or axially or both rotationally and axially shifted from the first pattern of lesions. The first and second patterns of lesion together comprise the composite lesion.

Abstract: Methods treat a tissue region. In one arrangement, the methods deploy an electrode on a support structure in a tissue region at or near the cardia of the stomach. In one embodiment, the support structure has a proximal region and a distal region. The proximal region is enlarged in comparison to the distal region, and the electrode is carried by the enlarged proximal surface. The methods advance the electrode in a path to penetrate the tissue region and couple the electrode to a source of radio frequency energy to ohmically heat tissue and create a lesion in the tissue region.
