Surface coatings for catheters, direct contacting diagnostic and therapeutic devices

摘要: A catheter including a distal end assembly having an external surface coating. Where the includes electrodes or other electrical components, coating is preferably electrically conductive. Such conductive formed from material comprising regenerated cellulose, although materials such as hydrogel plastic component are utilizable. optical ultrasonic cellulose suitable. The robustness of permits manufacture and utilization electrode configurations that on non-conductive base member by processes pad printing, vapor deposition, ion beam assisted electroplating printed circuit manufacturing processes. Additionally, because produces smooth outer to assembly, lead wires temperature sensing devices can be bonded exterior then coated produce surface; thus providing simple, inexpensive method for attachment components electrodes.
