Abstract: Described embodiments include a system, apparatus, and method. A described system includes a power-receiving connector configured to be usable after sterilization, to releasably couple with a power-source connector, and configured to be carried by a health care provider proximate to a first body portion. If coupled, the power-receiving connector is operable to receive an electrical or radiant power from the power-source connector. The system also includes a power-output device configured to be usable after sterilization, to interact with a power-receiving device connected to a handheld medical device, and configured to be carried by the health care provider proximate to a second body portion. If interacting, the received electrical or radiant power is transferred from the power-output device to the power-receiving device.
