First Claim
1. A system for transmission of power between a first location external of a living body and a second position internal of the living body which comprises:
- (a) a primary controller comprising a power source and a transmitter, locatable at the first location; and
(b) an antenna based device locatable at the second position to receive an output from the transmitter, said antenna based device including a capacitor, wherein the power source is adapted to emit high frequency electromagnetic radiation between 0.5 to 5 GHz; and
wherein, in use, the antenna based device converts the transmitted power to electrical energy which is used to operate the antenna based device, wherein the primary controller and the antenna based device do not communicate by inductive coupling; and
wherein the primary controller is capable of transmitting power to the antenna based device from at least about 50 cm.

Abstract
There is provided a system for transmission of power and/or information between a first location external of a living body and a second position internal of the living body which comprises: (a) a primary controller (2) comprising a power source and a transmitter locatable at the first locations; and (b) an antenna (12) based device (10) locatable at the second position to receive an output from the transmitter, wherein the power source is adapted to emit high frequency electromagnetic radiation between 0.5 to 5 GHz. A medical appliance comprising a spring-based stent incorporating a monitoring device wherein the spring of the stent acts as the aerial for the monitoring device and wherein the medical appliance is capable of receiving electromagnetic radiation with a frequency between 0.5 to 5 GHz.

26. A method for transmitting power between a first location external of a living body at which a primary controller is located, wherein the primary controller comprises a power source and a transmitter and a second position internal of the living body at which the antenna based device is located, said antenna based device comprising a capacitor, the method comprising the steps of:
-
(a) generating high frequency electromagnetic radiation between 0.5 to 5 GHz from the power source and emitting that radiation from the transmitter of the primary controller, (b) receiving the radiation at the antenna based device, and (c) powering the antenna based device with the radiation;
wherein the primary controller and antenna-based device do not communicate by inductive coupling; and
wherein the primary controller is capable of transmitting power to the antenna based device from at least about 50 cm. - View Dependent Claims (27, 28)
