Wirelessly powered implantable medical device system and methods thereof

An implantable medical device comprising:

• a main body;
• a motor disposed within the main body;
• an extension rod operably coupled to the motor and configured to slide relative to the main body in response to operation of the motor;
• and
• a receive antenna configured to receive a power signal from an external controller, the power signal providing electrical power for operating the motor, wherein the implantable medical device is devoid of an onboard power storage device and is configured to operate solely from power received via the power signal from the external controller.

An implantable medical device comprising:

• a main body defining a first compartment;
• an extension rod slidably coupled with the main body and at least partially disposed in the first compartment, the extension rod being movable between a retracted position, an extended position, and a sterilization position;
• a sealing arrangement disposed between the main body and the extension rod;
• wherein:
• the extension rod includes a proximal end, a distal end, and a tapered portion disposed between the proximal end and the distal end;
• and
• when the extension rod is in the sterilization position, the tapered portion is withdrawn from the sealing arrangement to create a flow path between the extension rod and the sealing arrangement that allows sterilizing gas to flow into the first compartment.

A method for sterilizing an implantable medical device, comprising:

• providing an implantable medical device having an extension rod that is at least partially disposed in a compartment of the implantable medical device and that is movable between a starting position and a sterilization position, the extension rod including a tapered portion;
• positioning the extension rod in the sterilization position such that the tapered portion creates a flow path for sterilizing gas to enter the compartment of the implantable medical device;
• placing the implantable medical device in a sealable pouch;
• introducing sterilizing gas into the sealable pouch such that the sterilizing gas flows through the flow path into the compartment;
• maintaining the sterilizing gas in contact with surfaces within the internal compartments for a predetermined time;
• and
• moving the extension rod from the sterilization position to the starting position after sterilization is complete.
