Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction. In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which propels a ball of food (called a bolus while in the esophagus and upper gastrointestinal tract and chyme in the stomach) along the tract. Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward.
Method and apparatus to treat disorders of gastrointestinal peristalsis
InactiveUS6895279B2Avoid damageAccurately localized and precisely graded electrical fieldsInternal electrodesExternal electrodesDiseasePeristalsis
Many patients suffer from diseases and surgical damage that result in failure of the stomach and intestinal tract to contract and relax normally in order to transfer contents distally. Electrical stimulation applied to one or more sites on the surface of the gastrointestinal viscera can treat this problem by triggering or altering muscle contractility. The present invention provides such stimulation by implanting leadless microstimulators in or on the walls of the viscera that can be programmed or controlled from a source outside the body.

A swallow challenge medium (10) is thixotropic for easy swallowing and to provide enough viscosity for effective challenge to peristalsis (20) and has high ionic density for effective impedance measurements by contact with electrodes (41–48) positioned in a person's esophagus (E) or oropharynx during swallow testing. The medium (10) also has a high surface tension so as not to adhere to or coat the electrodes (41–48) or probe (12) surfaces. These physical characteristics are stabilized and consistent enough to provide standard for esophageal and / or oropharyngeal function testing and diagnostics.

Self-stabilizing encapsulated imaging system
Wireless capsule endoscope technology has been used to image portions of the gastrointestinal (GI) tract, particularly the small bowel. However in other GI organs, especially those having larger-lumens, the capsule may become destabilized and tumble, precluding meaningful interpretation of the acquired images. The present invention describes a method and apparatus for permitting capsule imaging of organs having larger-lumens without tumbling, and includes an outer shell surrounding the capsule that targets the colon, as an example. Once the colon has been reached, the shell breaks or dissolves, and allows expansion of expandable materials attached to each end of the capsule, thereby stabilizing the capsule in the targeted organ, while permitting it to be moved by peristalsis and / or other means for locating the capsule. Imagers and light emitting diodes (LEDs) are activated during the expansion process, and enable overlapping of images. The capsule is moved through the colon, taking images at chosen frame rates with data being wirelessly transmitted by means of an RF transmitter, and is eventually expelled from the body.
