    摘要： An implanted medical device (IMD) conserves power by discriminating received radio frequency (RF) signals between noise and data based on frequency. Data is processed while noise is attenuated. The IMD operates in a first, relatively low, power mode while not receiving the RF signals, in a second, higher, power mode responsive to receiving RF signals, and operates in still higher power mode when the RF signals' average frequency over a selected period is within a predetermined range. A receiver circuit receives RF signals and discriminates a data signal from noise based on average frequency of the RF signals over selected time periods. The receiver circuit operates in a power-conserving mode unless it receives RF signals, or otherwise operates in a relatively higher-power mode. The receiver transfers signals to a telemetry circuit that operates in a power-conserving mode until it receives a valid data signal to operate in higher power mode.

    摘要： An implantable medical lead includes a device, such as a physiological sensor, that is coupled to one or more stimulation/sensing sensing conductors within the lead. When the implantable medical lead is coupled to an implantable medical device, the device carried by the lead both receives power from, and communicates with the implantable medical device via the one or more stimulation/sensing sensing conductors. Each of the one or more stimulation/sensing sensing conductors is also coupled to an electrode that is exposed to body tissue.

    摘要： An implantable medical device communication system communicates information between an implantable medical device and at least one slave device by way of a two-wire bus. Slave devices may include remote sensors, actuators and other implantable medical devices. The implantable medical device includes a communication unit to output commands and power pulses, and receive information from the slave devices over the two-wire bus. The implantable medical device and slaves communicate over the bus by selectively changing one of the lines of the bus between a first and second voltage, the second voltage substantially equal to a reference voltage of the second line, e.g., zero volts. In some embodiments, the power pulses take the form of bipolar pulse pairs. The slave device includes a recovery unit to recover power from the power pulses.

    摘要： In an implanted medical device, a method and apparatus for detecting pressure waves caused by movement of a body organ, muscle group, limb or the like and transmitted through a catheter or lead body to the implanted medical device employing a pressure wave transducer mounted in relation to the proximal end of the catheter or lead to detect the transmitted pressure waves. The system may also include a reference transducer having the same pressure wave response characteristics as the pressure wave transducer but isolated from the proximal connector end for providing a reference signal including common mode pressure wave noise that both transducers are simultaneously subjected to. The pressure wave signal and the reference signal are preferably amplified, bandpass filtered to the body pressure wave of interest and stored, telemetered out or used to trigger a device operation. The pressure and reference wave transducers preferably are piezoelectric crystal transducers or accelerometers in direct or indirect mechanical contact with the proximal connector end of the catheter and is encapsulated from the body within a device connector assembly. Preferably, the catheter is a lead extending into direct or indirect contact with the patient's heart. Cardiac pressure waves and respiration pressure waves are both transmitted proximally through the lead body to the pressure wave transducer. Pressure wave signals may be derived in parallel to detect particular characteristics of the cardiac and/or respiratory cycle to provide timing signal(s) for controlling the device operations.

    摘要： A capture verification system for a cardiac pacemaker comprising an implantable pulse generator (IPG) and one or more pacing leads having a proximal end coupled to the IPG and a distal end in contact with a patient's heart. The capture verification system employs a pressure wave sensor mounted in the IPG in relation to the proximal end of the pacing lead for sensing pressure waves transmitted from the distal end of the pacing lead to the proximal end thereof. The pressure waves include characteristic sounds of heart contraction and/or distal end lead motion caused by the contraction motion of the patient's heart that are transmitted along the lead body to the active sensor. A further isolated, reference sensor is also incorporated into the IPG in a similar fashion. Signal processors are coupled to the pressure wave and reference sensors for nulling out common mode noise.

    摘要： In the present disclosure, conservation of an implantable medical device power supply of is facilitated by controlling the power consumption of the device's processing component. The power supplied to the processing component is controlled to enable processing of received events as a function of predetermined criteria rather than the actual occurrence of the events which is frequent, but irregular. Accordingly, the need for the processing component to start and stop (and thereby be fully powered on each start) with receipt of each event is obviated thereby maintaining the power consumption of the processing component and increasing longevity of the device. Event data associated with received events is stored in an event queue and subsequently retrieved and transmitted for processing based on predetermined criteria. The power supplied during an idle state of the processing component may be reduced in relation to the power supplied during a wake up state.
