Abstract
The invention provides methods and devices to reduce stomach acid secretion in a patient with a hyper acid condition. For example, the invention may involve ablation of the stomach lining to destroy acid-producing cells. Destroying acid-producing cells may reduce the amount of stomach acid produced and, therefore the amount of acid refluxed in the esophagus. The invention may further provide methods and devices to monitor the esophageal acid level before and after the ablation procedure.
Claims26
A method for reducing stomach acid secretion comprising:
- determining a first acid level of a patient with a hyperacid condition;
- temporarily impairing functionality of a gastro-intestinal tract of the patient;
- ablating tissue within a stomach with an ablation probe sized to fit the stomach to inhibit the production of acid by the tissue;
- and
- determining a second acid level of the patient following a period of time sufficient to allow the gastro-intestinal tract to regain functionality after ablation.

A method for reducing stomach acid secretion comprising:
- determining a first acid level of a patient with a hyperacid condition;
- ablating tissue within a stomach with an ablation probe sized to fit the stomach to inhibit the production of acid by the tissue;
- determining a second acid level of the patient one week after ablation;
- and
- comparing the second acid level with the first acid level to determine whether the second level is lower than the first acid level.
