Abstract
A retention catheter in which a closed forward end portion of the drainage tube is provided with a pair of resilient inflatable bags which serve to retain the catheter end in an established drainage position. The bags extend circumferentially about the tube in diametrical opposition and along the same length portion of the tube, with the circumferential extent of each bag being so limited as to define on the tube wall a pair of opposed oblong open windows through which fluid drainage occurs. One duct extends along the tube wall to carry fluid for inflating the bags, and another duct communicates the bags with each other to equalize their inflation.
