摘要:
Medical data is communicated from a transmitter of an external unit to a receiver of an implantable medical device. The transmitter generates a preamble signal having encoded configuration data that informs the receiver of configuration settings to be used in receiving the medical data. The receiver detects the preamble and validates a modulation pattern of the preamble. Configuration data is decoded from the preamble signal and the receiver configuration is adjusted to receive the medical data.
摘要:
An implantable medical device (“IMD”) configured in accordance with an example embodiment of the invention generally includes a housing, a connector header block coupled to the housing, a dielectric sheath located around at least a portion of the housing and/or around at least a portion of the header block, and a telemetry antenna located within the dielectric sheath. The antenna is configured to support far field telemetry with an external device such as a programmer. In one example embodiment, the antenna is configured as a balanced antenna having two separate antenna elements driven 180 degrees out of phase. Each of the antenna elements has a feed point on a perimeter edge of the IMD housing and a floating endpoint. A number of alternate embodiments are also provided.
