Technology of Surface Modification of CatheterSuper Lubricating Hydrophilic Coating And Application The Principle of Lubrication The surface of catheter is covered with hydrophilic polymer by coupled action of a coupling agent. The principle is that one end of coupling agent is connected to the hydrophobic group on the surface of the catheter, the other end is connected to the hydrophilic polymer. The hydrophilic polymer on the surface will dissolve and expand quickly when the catheter meets water. So it shows super lubricating property. The hydrogel surface has high water-retention abilities and remains self-lubricating throughout the entire catheterization insertion and withdrawal process. The hydrogel surface minimizes the incidence of complications and recurrent infections The Principle of Lubrication The surface of catheter is covered with hydrophilic polymer by coupled action of a coupling agent.

The hydrogel surface minimizes the incidence of complications and recurrent infections Characteristic of Technology The surface of the catheter is just like the loach, patients have no pain in the catheterizing operation. The lubricating coat keeps stable and is not easy to separate from the surface for a long time. Good biocompatibility---do not cause intraluminal tissue infection. Need no paraffin oil lubricant, which can minimize irritation to intraluminal tissue. Convenient operation--- easy to pass through human luminal stricture or scar, and no need to dilate the human lumen.
