Abstract
A perfusion catheter is designed to be used both as an exploring catheter for measuring potential difference across the gastrointestinal wall and for simultaneous measurement of pressure at the same site. The catheter includes a perfusion lumen into which an Ag/AgCl wire is inserted as an electrode thus avoiding the need of half cells and bridges. By perfusing saline around the wire, the environment is kept constant around the wire, a prerequisite for the electrode. The flow rate of the distal end of the lumen is altered by making the diameter of the outlet different to the diameter of the lumen. The perfused solution is also used to measure pressure.
