Abstract
A distal electrode of an electrode assembly, for example, employed by an implantable medical electrical lead device, extends distally from a distal terminal end of a sleeve of the assembly; and the sleeve, which defines a longitudinal axis of the assembly, includes a plurality of channels that provide fluid communication between a steroid eluting component, which is seated in an external groove of the sleeve, and an area distal to the distal terminal end of the sleeve. Floors of some or all of the sleeve channels may angle toward the longitudinal axis of the assembly, being closer to the axis at the distal terminal end of the sleeve. The assembly may further include a proximal electrode secured to a proximal end of the sleeve, wherein the proximal electrode may be mounted around an outer surface of the sleeve or coupled to the sleeve by means of a coupling component.
