Abstract

A medical electrical lead having an elongated lead body carrying multiple conductors (104, 106, 108, 110), wherein the lead body comprises: an inner core member (102) having radially extending grooves therebetween along the length of the core (102), an outer tubular member (100) surrounding the core, and conductors (104, 106, 108, 110) located in said one or more of the longitudinally extending grooves of the core. The dimension of the longitudinally extending grooves at the outer periphery of the core is less than the maximum internal dimension of the grooves.
