PROBLEM TO BE SOLVED: To provide medical electrostimulation electrodes the electrode support for which can be reduced in the outer diameter when the electrodes are withdrawn.SOLUTION: Medical electrostimulation electrodes 1 inserted into a blood vessel and used to stimulate nerves from inner walls of the blood vessel, comprise: stimulating electrode parts 10, 11 for providing electrical stimulations through inner walls of a blood vessel; a linear lead part 20 for insertion of a wiring electrically connected to the stimulating electrode parts; and an electrode support 25 which is formed of linear elastic members 26A, 26B, 26C in a shape of a cage substantially rotationally symmetrical about a certain axis C, and has stimulating electrode parts in portions of the elastic members, and one end of which in an axial direction is connected to an end of the lead part. The electrode support is formed so as to protrude radially outwardly from outer surfaces of the elastic members and has a plurality of projecting parts 30 in different positions in the axial direction when the diameter of the electrode support is reduced.SELECTED DRAWING: Figure 2 |
