A positive fixation cardiac lead includes an electrode sleeve/crimp tube assembly in which a recess is formed for retaining a drug impregnated matrix. The electrode sleeve and crimp tube threadedly engage, to permit insertion of the matrix prior to their assembly. The distal end section of the crimp tube can be provided with a helical groove corresponding to the shape of a fixation helix, with the sleeve and distal section spaced from one another to permit insertion of an annular drug matrix. The distal portion of the electrode sleeve can have an annular groove formed to receive a length of platinum wire, for increased electrode sensitivity.
