    摘要： An implantable lead having a silicone rubber lead body which has a reduced coefficient of friction on an internal or external surface. The reduction in coefficient of friction is accomplished by extruding a tubular lead body to define a plurality of small parallel longitudinally extending grooves on the inner or outer surface of the lead body. The grooves may be formed by means of a die having inwardly or outwardly directed projections that form the grooves during the extrusion process. The formation of the grooves during extrusion provides a lead body having a lower coefficient of friction without the necessity of additional manufacturing process steps and without additional manufacturing costs.

    摘要： A medical electrical lead having an elongated lead body carrying a conductor therein, the lead body being formed of an inner sleeve of a first, relatively more rigid plastic and an outer sheath of a second, relatively less rigid plastic, the inner sleeve having a tubular portion and having outwardly extending helical ridges extending along its length, the ridges having lateral wall surfaces extending radially from the tubular portion and an outer sheath over the inner sleeve and in contact with the lateral wall surfaces of the inner sleeve. A fixation helix may be mounted at the distal end of the lead body and a conductor, which is also rotatable relative to the lead body may be located within the inner, tubular sleeve. Conductors may also be located between the ridges of the inner sleeve, embedded in the outer sheath.
