Abstract: 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.
