An implantable electrode arrangement (1) for stimulating excitable tissue, in particular the neosphincter to control urinary incontinence. The electrode is in the form of a extending peg with a pair of electrode elements (2, 3) extending from a base (4). The elements are arranged to fit over the tissue to be stimulated and have electrodes (5, 6) on the inner surfaces of the peg portions. The tissue located between the peg portions receives stimulation. Also disclosed are methods of treating urinary incontinence by electrically stimulating a band of smooth muscle and electrode having an insulating member and electrodes on the inner surface such that an electric field applied to tissue is confined.
