Abstract
An implantable electrode lead has a proximal end intended for connection to, e.g., a pacemaker and has a distal end with an electrode head equipped with an external, tine-type anchoring unit. The anchoring unit has a number of projections which are integrally formed as a one-piece unit together with a ring-shaped carrier. The carrier is made of an elastic material, and is disposed under elastic tension in an annular groove in the exterior of the electrode head, which fixes the position of the anchoring unit relative to the electrode head. The anchoring unit detaches from the electrode head, by the carrier being pulled out of the groove, when a predetermined, minimum pulling force is exerted on the electrode head from the proximal end of the lead.
