    Abstract: An implantable cardiac rhythm management (CRM) device includes a sensing and detection circuit that senses at least one cardiac signal and detects cardiac electrical events from the sensed cardiac signal using a detection threshold that is adjusted based on a dynamic noise estimation. The sensed cardiac signal is filtered to produce a filtered cardiac signal having a signal frequency band and a noise signal having a noise frequency band. The noise frequency band is substantially different from the signal frequency band. A dynamic noise floor is produced based on the noise signal and used as the minimum value for the detection threshold. A cardiac electrical is detected when the amplitude of the filtered cardiac signal exceeds the detection threshold.

    Abstract: An implantable medical device comprising a far field RF transmitter and receiver, a controller circuit communicatively coupled to the RF transmitter and receiver, and a wakeup timer circuit integral to, or communicatively coupled to, the controller. The controller is configured to initiate power up of the RF transmitter and receiver during a wakeup interval defined by the wakeup timer circuit, detect a digital key received from a second device during the wakeup interval, transmit a response using the RF transmitter when the digital key is received, and receive a communication from the second device and resynchronize the wake-up timer according to a time of the communication.

    Abstract: Miniature defibrillators and cardioverters detect abnormal heart rhythms and automatically apply electrical therapy to restore normal heart function. Critical components in these devices are aluminum electrolytic capacitors, which store and deliver one or more life-saving bursts of electric charge to a heart of a patient. This type of capacitor requires regular “reform” to preserve its charging efficiency over time. Because reform expends valuable battery life, manufacturers developed wet-tantalum capacitors, which are generally understood not to require reform. Yet, the present inventors discovered through extensive study that wet-tantalum capacitors exhibit progressively worse charging efficiency over time. Accordingly, to address this problem, the inventors devised unique reform techniques for wet-tantalum capacitors. One exemplary technique entails charging wet-tantalum capacitors to a voltage equal to about 90% of their rated voltage and maintaining this voltage for about five minutes before discharging them.

    Abstract: 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.
