Abstract
A catheter for measuring motility and peristalsis in tubular organs that transport their contents by simultaneous, multiple impedance measurements includes an insulating plastic tube, conductive annular electrodes and interior channels for electrode leads. The electrodes also serve for biosignal detection and electrical stimulation of the organ being measured. The interior channels may be used to stiffen the catheter during use, remove sample materials from the organ for analysis and/or introduce substances to the organ such as a contrast medium.
