ABSTRACT:
A catheter for making pressure measurements in a sphincter canal. The example illustrated is for an anal sphincter canal. It has an inflation tube and water-perfusion tubes or lumens in a unitary, elongated body. A balloon or cuff is inflatable through the inflation tube. The body has a section in which the water-perfusion tubes are helically wound about the inflation tube which is centrally located. The water-perfusion tubes have side openings communicating with the lumens therewithin. These side openings are positioned along a line parallel to the longitudinal axis. Examples are shown where these side openings are located in one, two or four quadrants of the catheter surface, at different axial levels.
