Abstract

An electrode catheter comprising: a catheter body (10) having one or more inner pores; a control handle (20) connected to the base end of the catheter body (10); and a catheter tip (30) which is connected to the top end of the catheter body (10), which has an inner pore communicatively connected to at least one of the inner pores of the catheter body (10), and which is formed in a circular, loop-like shape, wherein the catheter tip (30) has two or more ring-shaped electrodes (31) attached around the rim thereof and also has a spherical chip electrode (32) attached to the end part thereof. The electrode catheter can measure a potential almoston the whole area of the catheter tip and hardly damages the inner wall of a blood vessel with the end part of the catheter tip.
