Antenna for an implantable medical device

This invention describes an antenna for medical devices implanted inside the body, such as in blood vessels. It uses a small electronic module within the device's main housing to send signals to an inner wire loop. This loop then wirelessly transfers the signals to a separate, stent-like structure that anchors the device to a vessel wall, allowing the stent itself to act as the main antenna for radiating signals.

Why it matters: Filed before significant advancements in miniaturized, low-power telemetry modules and biocompatible conductive materials. These could now enable a more compact and efficient stent-antenna design, improving feasibility for long-term implantation.
