A corporeal access tube assembly including a tube segment in which a coil spring is embedded along a portion of the segment. A retention balloon is secured to the tube segment around a portion which does not contain the coil spring. The balloon is inflated when in operation but its walls are not stretched to any noticeable extent. The tube segment extends through a split external bolster which opens to permit positioning of the tube segment and closes to clamp the tube segment in place. A gauging system on the tube segment permits precise positioning of the bolster.
