Abstract:
The catheter has a retainer/seal made of soft material glued to the inside circumference at its opening. The catheter is applied by inserting the penis head into the opening and pulling the catheter retainer/seal onto the penis shaft. The excess material at the opening is wrapped around the shaft of the penis and secured with a short length of tape applied to the outside of the catheter. The retainer/seal encircles the penis shaft just proximal to the penis head. The lower (distal) surface of the retainer/seal shoulders up against the ridge formed by the penis head. The diameter of the penis shaft is less than the diameter of the penis head at its proximal end. Because the retainer/seal has been fitted to the smaller diameter penis shaft, the catheter cannot be removed without deforming the penis head.
