Gastrointestinal intraluminal pressures have been recorded in eight patients by a pressure-sensitive telemetering capsule energized by an external, wireless source. The capsule is smaller and simpler than a battery-powered capsule, and has a relatively unlimited life. The pressure records are similar to those obtained by other sensing devices.
