ABSTRACT:
An electrode arrangement for in vivo stimulation of tissue with electrical energy has a catheter containing an electrical lead, the lead and the catheter being electrically and mechanically connected to further electrical conductors, arranged in a configuration forming a broad, flat, thin and flexible electrode. The conductors in the electrode are partially exposed and define an electrode surface for delivering electrical energy to adjacent tissue. The electrode arrangement further includes a fixing device, for attaching the electrode to tissue surrounding the tissue to be stimulated. The fixing device includes a fixing element which is mounted on the electrode so as to be movable independently of the electrode, and a stylet which controls movement of the fixing element, the stylet extending through the catheter. The fixing element can be controlled so as to be advanced from a retracted position to a position extending beyond the electrode surface in which the fixing element penetrates the tissue.
