Patent Images
1. A system comprising:
- a detachable helical antenna comprising;
a first threaded portion;
an electrically insulated portion coupled to the first threaded portion; and
a conductive portion at least partially contained within the electrically insulated portion;
wherein the detachable helical antenna is configured to use the first threaded portion to threadably engage an implantable medical device assembly;
wherein the implantable medical device assembly includes an implantable telemetry circuit configured to wirelessly transfer information electromagnetically using the detachable helical antenna;
wherein the detachable helical antenna includes a tapered profile having a decreasing outer radius in a direction distal to the first threaded portion; and
wherein the conductive portion includes two or more concentric helical portions including a tapered helical portion.
