Physiologic analyzers that determine the peristaltic smooth movement of some part of the digestive tract (e.g., esophagus, stomach, small intestine, colon) and the intraluminal pressure exerted in its content. Some of these analyzers can evaluate motility in several areas of the intestinal tract using interchangeable dedicated catheters. These analyzers may include catheters that either use a manometric sensor in the tip to measure the pressure directly (nonperfusion catheter) or are connected to extracorporeal pressure transducers to measure the pressure indirectly (perfusion catheters). Motility analyzers usually have multichannel capabilities for measuring pressure at several points simultaneously, as well as some additional sensors to perform other measurements of interest (e.g., pH); they may also include computing capabilities for data processing and recording.
