Operatively coupled data and power transfer device for medical guidewires and catheters with sensors

A power and data coupling device for medical sensors comprising:

• a first conductive surface integrated into a medical device and configured to couple via an electric field with a second conductive surface, the medical device configured to remain outside a human body, the second conductive surface configured to be translatable with respect to the first conductive surface, wherein:
• the first conductive surface is connected to a power source for providing power, through the electric field, to the second conductive surface,
• the first conductive surface is configured to radiate a time-varying electric field that is configured to convey power to the second conductive surface, and
• the first conductive surface is connected to a pick-up that is configured to receive data signals from the second conductive surface, the data signals comprising data received from the medical sensors in electrical communication with the second conductive surface;
• wherein the first conductive surface is configured to simultaneously (i) provide multiple, different power signals to the second conductive surface, each power signal in the multiple, different power signals is configured to provide power to a different set of medical sensors and (ii) receive multiple, different data signals from the second conductive surface, each data signal in the multiple, different data signals provides data from a different group of medical sensors.
