An electro catheter for neurostimulation includes a stimulation end of essentially helical shape, suited to be wrapped around a nerve. The stimulation end is deformable, meaning that it has a helical shape that can be modified in diameter and/or pitch, according to the dimensions of the nerve to be wrapped, and can be modified even to the point of assuming an essentially rectilinear linear shape according to the profile of the nerve, so that it is suited to be positioned in proximity to the nerve, along its profile.
