Method to treat gastric reflux via the detection and ablation of gastro-esophageal nerves and receptors
View Patent ↗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.
1. A method comprising
detecting 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,
treating 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,
conducting a cooling solution to the tissue site at a flow rate,
measuring temperature at or near the tissue site,
comparing the measured temperature to a desired temperature,
increasing the flow rate of the cooling solution to the tissue site if the measured temperature exceeds the desired temperature, and
maintaining the flow rate of the cooling solution to the tissue site if the measured temperature does not exceed the desired temperature.
2. A method according to claim 1 , further comprising:
imaging the tissue site.
