Surface coatings for catheters, direct contacting diagnostic and therapeutic devices

Abstract

A method for manufacturing a catheter assembly including a handle, a guide tube having a proximal end engaged with the handle, and a distal end assembly engaged with a distal end of the guide tube. The method includes applying an active electrode element on the distal end assembly by a process selected from the group consisting of electroplating, vapor deposition, IBAD and pad printing, and applying a regenerated cellulose coating over the distal end assembly. The regenerated cellulose coating is applied by applying a viscous liquid coating to the catheter distal end assembly, regenerating the viscous coating, and then curing the regenerated coating. The cured coating is preferably hydrated.
