Method for producing an ablation catheter comprising flushing passages

Abstract

A method producing a catheter body comprising flushing passages, including steps of: a) providing a hollow-cylindrical inner liner with an inner lumen and a radially outer inner liner outer surface; b) providing a flexible circuit board comprising a plurality of electrical conductors; c) arranging the flexible circuit board on the inner liner outer surface; d) sheathing the inner liner and the flexible circuit board with an outer insulation; e) establishing a connection between the inner liner and the outer insulation so that the flexible circuit board is fixed between the inner liner and the outer insulation; f) providing at least one electrode; g) establishing electrical contact between the at least one electrode and at least one of the electrical conductors of the flexible circuit board; and, h) creating a plurality of flushing passages which fluidically connect the inner lumen to a surface of the catheter body.
