Abstract
A passive fixation, body implantable lead assembly has a cylindrical tip electrode whose outer side surface is covered with a thin dielectric insulating layer so as to mask an active, disk-shaped electrode surface at the distal extremity of the tip electrode. The active electrode surface preferably has an area less than about 1 mm . An MCRD, in the form of a collar, may be carried by a proximal portion of the tip electrode. Supplementing a set of main tines projecting from the distal end portion of an insulating sheath housing the lead assembly is a set of nubby auxiliary tines extending from the sheath immediately adjacent the distal extremity thereof.
