Abstract: Techniques for use with an implantable medical device (IMD) reduce how often a first receiver of the IMD wakes up a second receiver thereof to reduce power consumption. A received message and/or a channel over which messages can be received is/are examined, and a value is adjusted based on results thereof. After being adjusted, the value is compared to a first threshold if the IMD is in a normal state, or compared to a second threshold if the IMD is in a noise state. If in the normal state, there is a determination whether to stay in the normal state or switch to the noise state. If in the noise state, there is a determination whether to stay in the noise state or switch to the normal state. At least the second receiver is temporarily put to sleep, if the IMD is maintained in or switched to the noise state.

Abstract: Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and performing error detection and correction on the message. Such a method can also include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.

Abstract: Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and measuring a message interval indicative of a length of time between when the message was received and when a preceding message was received. The method can also include determining, based on the measured message interval, whether the message was received within the message window, and determining whether to reject the message based on results thereof. The method can also include adjusting a temporal position of the message window based on the measured message interval. The method can further include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.

CPC classification number: A61N1/3655 , A61N1/3756
Abstract: A cardiac rhythm management system provides an increase in pacing rate as a combination of responses to three characteristics of a relative-temperature signal: a dip, a positive slope, and a positive magnitude. The relative-temperature signal is the difference between a short-term and a long-term temperature average. A dip produces a limited and temporary rate increase having a first proportionality. A positive slope produces a rate increase with a second proportionality. A positive magnitude produces a rate increase with a third proportionality. The dip response seeds the slope response to provide a seamless and immediate rate transition after a dip. The cardiac rhythm management system limits and filters the sum of the rate increases to provide a sensor indicated rate, which is used to stimulate the heart.

Abstract: In accordance with an embodiment, a system and method is provided for providing communications between first and second implantable medical devices (IMDs). The system comprises a first implantable medical device (IMD) configured to transmit a first event message during or preceding a first cardiac cycle, and a second IMD configured to receive the first event message, wherein receipt of the first event message configures the second IMD to generate pacing pulses for only a predetermined number (“n”) of consecutive cardiac cycles, wherein n is an integer equal to or greater than 2. The method comprises transmitting a first event message during or preceding a first cardiac cycle from the first IMD, receiving the first event message at the second IMD, in response to receiving the first event message, arming the second IMD to generate a pacing pulse for a second cardiac cycle, and arming the second IMD to generate a pacing pulse for only a predetermined number of consecutive cardiac cycles immediately subsequent to the second cardiac cycle.
