摘要：
A gastro-electrical activity mapping system and comprises a catheter insertable through a natural orifice into the gastro-intestinal (GI) tract and comprising an array of electrodes for contacting an interior surface of a section of the GI tract to detect electrical potentials at multiple electrodes, and a signal analysis and mapping system arranged to receive and process electrical signals from multiple electrodes of the array and spatially map GI smooth muscle electrical activity as an activation time map, a velocity map, or an amplitude map, which may be in the form of contour plots and may be mapped on an anatomical computer model of at least the section of the GI tract and may be animated. A GI mapping method and catheter are also claimed.
