A closed-system urinary catheter with a low viscosity gel lubrication is disclosed. The system has an uncoated catheter, but a hydrophilic coated catheter could be used. The low viscosity lubricating gel within the sachet uniformly coats the catheter when the sachet is ruptured just prior to use. A low viscosity lubrication gel could alternatively be place in the area inside the sheath and external to the catheter. Therefore, the variability that occurs with a hydrophilic catheter or the areas of a non-lubricated catheter with the higher viscosity gel catheters is avoided.
