Ablation of exterior of stomach to treat obesity
First Claim
Patent Images
1. A method for treating obesity comprising ablating tissue on an exterior surface of a stomach of a patient with an ablation probe sized to fit the stomach and further comprising:
- monitoring gastric myoelectric activity of the stomach prior to the ablation to determine a baseline digestion rate;
monitoring the gastric myoelectric activity of the stomach after the ablation to determine a post-ablation digestion rate; and
ablating additional stomach tissue based on a comparison of the post-ablation digestion rate to the baseline digestion rate.

Abstract
The invention provides methods and devices to treat obesity by ablating tissue from an exterior surface of a stomach of a patient. For example, the invention may involve ablation of exterior stomach tissue to alter gastric myoelectric activity or muscle function from the exterior surface of the stomach to produce abnormal gastric peristalsis without damaging the mucosal lining of the stomach. The invention may further provide methods and devices to monitor the gastric myoelectric activity before and after the ablation procedure.

7. A method comprising:
-
ablating tissue on an exterior surface of a stomach of a patient with an ablation probe sized to fit the stomach; and monitoring gastric activity of the stomach after the ablation, wherein monitoring gastric activity comprises assessing the impact of the ablation upon one of gastroparesis, nausea, and gastroesophageal reflax disease.
