An implantable medical device assembly comprises a sealed housing; a motor including a rotating output shaft within the sealed housing; a first coaxial shaft within the sealed housing, the first coaxial shaft being mechanically coupled to the rotating output shaft such that rotation of the rotating output shaft drives rotation of the first coaxial shaft; a second coaxial shaft external to the sealed housing, the second coaxial shaft being in axial alignment with the first coaxial shaft; an oscillating component mechanically coupling the first coaxial shaft to the second coaxial shaft, wherein rotation of the rotating first coaxial shaft drives the oscillation of the oscillating component, wherein the oscillation of the oscillating component drives rotation of the second coaxial shaft; and a flexible seal including the oscillating component. The sealed housing and the flexible seal combine to form a substantially sealed enclosure encasing the motor and the first coaxial shaft.

Various embodiments of this disclosure concern a lead end containing a slotted member. A slotted member can have a plurality of slots extending along at least a portion of the length of the slotted member, each of the slots having a respective positioning feature, the plurality of slots having a plurality of positioning features at different longitudinal positions along the length of the slotted member. The lead end can further include a plurality of conductors at least partially within the plurality of slots, each slot of the plurality of slots containing at least a respective one of the plurality of conductors, the plurality of conductors electrically connecting exposed electrical elements of both ends of the lead.
