A medical lead includes a pitted, grooved or threaded electrode array tip and a flexible tube or sheath encompassing the electrode array located near the lead tip. In some embodiments, the electrode array adheres to tissue, the tube or sheath adheres to the electrode array at the distal end of the electrode array or the tube or sheath adheres to tissue at the proximal end of the tube or sheath. Embodiments of the tube or sheath may be made from biodegradable material and can include electrode windows spaced along the tube or sheath corresponding to placement of electrode contacts of the electrode array.
