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.

Abstract: In one example, a medical device includes a housing having a channel configured to receive an electrical lead. The medical device can further have a rotatable member having a longitudinal axis about which the rotatable member is configured to rotate. The rotatable member can have an outer surface having a first radius from the longitudinal axis. The rotatable member can also have a cam lobe extending farther from the longitudinal axis than the first radius of the outer surface. The cam lobe can have a substantially planar surface parallel to the longitudinal axis. The substantially planar surface of the cam lobe can be configured to retain the electrical lead within the channel. The medical device can further have a slider having a central portion substantially parallel with the cam lobe. The slider can further have a slider protrusion on the central portion of the slider.

Abstract: An implantable medical device (IMD) includes a housing that is configured to enclose internal components including at least a processor and a power source. The housing defines two major surfaces that are generally parallel to each other and one or more channels that are each configured to receive a lead and electrically couple the respective lead to the internal components, where each of the channels extend substantially straight in to the housing along an axis generally parallel to the two major surfaces. The housing may be configured to be mounted to a cranium of a patient such that at least one of the two major surfaces approximates a curvature of the cranium. The IMD may include one or more funneling walls that define a rounded and smooth transition from a sidewall of the housing to a surface that defines one or more mouths to the channels.

Abstract: In some examples, an implantable medical device (IMD) including a hermetically sealed housing that is configured to enclose internal components. The internal components may include stimulation circuitry, processing circuitry configured to control the stimulation circuitry to deliver electrical stimulation using one or more leads received by the housing, telemetry circuitry, and a rechargeable power source. The IMD may also include a coil configured to at least one of receive energy to recharge the rechargeable power source or receive and/or transmit signals for wireless telemetry with another device, wherein the implantable medical device is configured to mount to a cranium of a patient, and wherein the coil is coiled about an axis that is approximately orthogonal to a major surface of the IMD.
