Abstract

An electrode array configured to be inserted at least partially into a blood vessel including: a self-expandable array body; at least two axially spaced-apart electrodes connected to said array body; wherein at least part of said array body expands to an open conformation and pushes at least one selected electrode against a blood vessel inner tissue with a force designed not to damage venous tissue.
