09343923 cites 431 patents.

An implantable medical device is disclosed that includes a charging coil configured to inductively couple to a first external coil to receive a charging signal to charge a charge storage element of the implantable medical device. The implantable medical device also includes a circuit coupled to the charging coil. The circuit includes a circuit component that, in response to the charging signal, generates a backscatter signal. The implantable medical device also includes a communication coil orthogonal to the charging coil and coupled to the circuit component. The communication coil is configured to inductively couple to a second external coil to communicate the backscatter signal to the second external coil.
