Transpyloric Shuttle (TPS) is a device used for the delivery of medication to the small intestine for the treatment of gastroparesis, a condition in which the stomach does not empty properly. The TPS is a tube with a small balloon on the end that is placed through the mouth, down the esophagus, and into the small intestine. Once the balloon reaches the small intestine, it is inflated to keep the TPS in place and release the medication into the small intestine over a period of time.
