  • Patent number: 10220185
    Abstract: A flushable catheter having an outer wall defining an inner conduit and an inner core member positioned within the inner conduit. The inner core being made from flushable materials, which are preferably degradable water soluble materials such that the inner core degrades as urine or water pass through the inner conduit defined by the outer wall.

  • Patent number: 8523843
    Abstract: A catheter assembly and method is disclosed which comprises a catheter having a coating on at least a part of its length intended to produce a low-friction surface on the catheter when treated with an activating substance in the form of a vapor. The catheter assembly also includes a catheter package forming an interior space divided by a gas permeable, liquid impermeable barrier into a first cavity and a second cavity. The first cavity of the catheter package accommodates the catheter therein and the second cavity accommodates at least a quantity of liquid in its liquid phase therein. The liquid in the second cavity can change phase into a vapor capable of passing from the second cavity, through the barrier, and into the first cavity where the vapor can activate the coating. As a result, the vapor produced when the liquid changes phase causes the coating on the catheter to be activated to thereby produce the low-friction surface on the catheter so it is ready-to-use when it reaches the end user.

  • Patent number: 8118797
    Abstract: A flushable biodegradable pouch having water-dispersible fibers along at least a portion of the outer surface of the pouch's cover layer provided with a water-soluble hydrophilic coating. The pouch's cover layer is water-disintegratable, and the water-soluble hydrophilic coating is a lubricating agent capable of becoming slippery when exposed to water and, upon subsequent drying, again becoming water-soluble upon re-exposure to water. As such, the hydrophilic coating serves as a rewettable, redesolving lubricating agent.
