    Abstract: A tethering assembly for securing a medical device includes a shaft and a wire that extends in sliding engagement within a proximal lumen, a channel, and a distal receptacle of the shaft. A retainer zone of the shaft, through which the channel extends, stops a transition segment of the wire, which extends between a proximal and a distal segment of the wire, from moving into the shaft receptacle, thereby restraining a distal-most tip of the wire from moving through a distal-most opening of the receptacle. When a projecting member of the device has entered a secure zone of the receptacle, via movement through the distal-most opening and a tapering passageway thereof, the distal-most tip of the wire, which may be spring-biased, can move distally into the passageway so that the tip blocks the projecting member from moving distally, back through the passageway.

    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.
