Abstract:
A method for forming an electrophysiology catheter with at least one electrode on the outer surface thereof comprising the steps of:providing a catheter body having an elongated flexible tubular member with an outer surface having a proximal end and a distal end; forming a coating of an electrically conductive material on said outer surface of said tubular member; forming a radial groove of predetermined axial length in said outer surface in the area within the coated area while maintaining the electrical conductivity of said conductive material; removing at least one portion of said coating within said groove so that at least two coated portions result that are electrically insulated from one another; forming a port hole in said groove in the area of said conductive material to create communication between the interior and exterior of said tubular member; extending an elongated flexible wire through said tubular member from said proximal end and out of said port hole; wrapping said wire around said coating within said groove, and filling said groove with an adhesive filler material to form a smooth substantially continuous outer surface on said catheter.
