Abstract
A process for manufacturing a flexible electrode catheter is disclosed. The process involves coating the catheter with an adhesive without affecting the integrity of the polymer substrate of the catheter. The process includes the steps of corona plasma treating a catheter, coating the catheter with an adhesive, baking the adhesive on the catheter, creating radial indents, and removing portions of the coating from the indented areas so that conduction between the different electrodes is broken. Portholes are then punched into the indented conductive areas and magnetic wires are inserted through the catheter and wrapped around the indented conductive areas. A small amount of formulated silver paint is then placed around the coiled magnetic wires. The entire indent, which includes the coiled wire and the area where the coating was removed, is then filled in radially with an adhesive coating.
