Abstract
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.
Claims20
A catheter system for draining a fluid, the system comprising:
- a catheter having an uncoated surface;
- an introducer coupled to a proximal end of the catheter, the introducer having a tip which is covered by a lubricant with a viscosity of greater than 2,000 cP;
- a sheath surrounding the catheter;
- and
- a pliable plastic foil sachet positioned loosely within the sheath and external to the catheter, the sachet containing a water-based gel having a viscosity of less than 2,000 cP.

- a sheath surrounding the catheter;
- a collection bag positioned at one of the catheter;
- and
- a pliable plastic foil sachet comprised of a pliable plastic foil type and positioned loosely within the sheath and external to the catheter, the sachet containing a water-based gel having a viscosity of less than 2,000 cP.
