Abstract

A tined lead that includes an insulated electrical conductor having one end electrically connectable to a pulse generator and an opposite end extending into one end portion of a metal electrode in electrically conductive relationship therewith, the opposite end portion of the electrode having a rounded tip for contacting body tissue, an axial bore through the tip surface to reduce the electrical conductive surface area of the tip and cross bores intersecting the axial bore remote from the tip, nonconductive, integrally joined plastic plugs filling said bores, and a nonconductive molded plastic member circumferentially surrounding the electrode, other than the tip, and the portion of the conductor that is connected to the electrode; the molded plastic member having a plurality of circumferentially spaced tines extending outwardly in a direction away from the tip. The tines are finned shaped and are flattened to be more flexible about axes parallel to the electrode axis than about axes perpendicular thereto.
