Abstract
Methods, systems, and devices for applying and utilizing a water-soluble polymer on a surface to provide desirable properties, attributes and/or characteristics to the surface. In a first embodiment, the water-soluble polymer at least partially fills one or more pores of a fluoropolymer or a porous metal. In a second implementation, the water-soluble polymer is mixed into a base material and the mixture is applied as a coating layer onto the surface. Where the surface is an electrosurgical electrode tip, the desirable properties, attributes and/or characteristics may include the ability to attract water that assists in cooling and/or lubricating the tip, to create a low shear, sacrificial layer that protects and enhances the tip, to supply a radical scavenger or inhibitor that reduces damage at the tip, and/or to deposit factors, such as healing factors, from the tip onto one or more contact surfaces of the patient's body.
