    Abstract: 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, and a telemetry antenna located within the header block. The header block is formed from a dielectric material, which encapsulates the antenna. The antenna is configured to support far field telemetry with an external device such as a programmer. In one example embodiment, the antenna is formed from a thin round wire, has a feed point on the top perimeter sidewall of the housing, and has a floating endpoint in the header block. The antenna is contoured to form a simple curve in a plane that is approximately parallel with the major sides of the housing.

    Abstract: 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.

    Abstract: A medical device including an elongate lead connected to a pulse generator connector further includes a passive lossy circuit electrically connected in between a distal portion of the lead conductor and the high frequency-grounded surface. The passive lossy circuit has a high frequency impedance approximately equal to a characteristic impedance of the lead when implanted in a body and dissipates energy of an incident wave formed along the lead, thereby diminishing a reflection of the incident wave, the incident wave being induced by exposure of the medical device to a high frequency electromagnetic field. The passive lossy circuit further has low pass properties allowing for normal device operation.

    Abstract: An implantable device, such as an implantable medical device (IMD) includes at least two radio frequency (RF) antennas and may additionally include an RF communication circuit. The RF antennas are spatially diverse, are disposed adjacent a housing, and are each configured to receive RF signals transmitted to the IMD from a remote RF signal source. The RF communication circuit, if included, is disposed within the housing and is configured to selectively receive the RF signals received by one or more of the spatially diverse RF antennas.
