Abstract

A system and method for transferring power includes a power transmitting unit for transmitting power and a power receiving unit for receiving power from the power transmitting unit. The power transmitting unit may be positioned outside a human body and the power receiving unit is located on an intrabody instrument adapted to be movable from the outside of the human body to inside the human body. The intrabody instrument may be a medical instrument connected to or incorporated within a robotic arm. The power transmitting unit may wirelessly transfer power to the power receiving unit in a continuous, non-interrupted manner.

Claims

1-20. -20. (canceled)
