摘要： One embodiment of the present invention relates to an implantable medical device (“IMD”) that can be programmed from one operational mode to another operational mode when in the presence of electro-magnetic interference (“EMI”). In accordance with this particular embodiment, the IMD includes a communication interface for receiving communication signals from an external device, such as a command to switch the IMD from a first operation mode to a second operation mode. The IMD further includes a processor in electrical communication with the communication interface, which is operable to switch or reprogram the IMD from the first operation mode to the second operation mode upon receiving a command to do so. In addition, the IMD includes a timer operable to measure a time period from when the processor switches the IMD to the second operation mode. In accordance with this aspect of the invention, the processor is in electrical communication with the timer, and is further operable to switch the IMD from the second operation mode back to the first operation mode when the measured time period reaches a predetermined time period.

摘要： A telemetry system enabling radio frequency (RF) communications between an implantable medical device and an external device, or programmer, in which the RF circuitry is normally maintained in a powered down state in order to conserve power. At synchronized wakeup intervals, one of the devices designated as a master device powers up its RF transmitter to request a communications session, and the other device designated as a slave device powers up its RF transmitter to listen for the request. Telemetry is conducted using a far field or near field communication link.

摘要： One embodiment of the present invention relates to a telemetry device which is in communication with an MRI system, and which is operable to communicate with an implantable medical device (IMD). The telemetry device includes a controller and telemetry circuitry. In one embodiment, the telemetry device is operable to automatically detect the presence of an IMD, and determine if the IMD is in an MRI-safe mode. If the IMD is not in an MRI-safe mode, the telemetry device can initiate processing to prevent the MRI system from conducting an MRI scan while the IMD in not in an MRI-safe mode.
