| The therapy uses a device, produced by BARRX Medical of Sunnyvale, Calif., that fits on the tip of a gastroscope, with a balloon that expands to fill the esophagus. |
| His work led to development of medical devices such as gastroscope, endoscope and bronchoscope. |
| When viewed with a gastroscope they look a little like mouth ulcers. |
| The gastroscope is a long, thin, flexible tube with a light, suction and camera. |
| While a gastroscope looks at the stomach, others, for example, can be inserted anally. |
| Patients are placed under local or general anesthesia and the stricture is dilated using a flexible gastroscope and Savary bougies. |
