  • Patent number: 8180428
    Abstract: A method and system for use in selecting a cardiac pacing site includes sensors for tracking wall motion (e.g., sensors coupled to the right and left ventricular heart wall). The wall motion of one or more non-paced cardiac cycles is compared to the wall motion of one or more paced cardiac cycles to determine the effectiveness of one or more pacing sites. For example, image data may be generated to notify the user as to the effectiveness of the one or more pacing sites.

  • Publication number: 20090125078
    Abstract: A method for selecting a cardiac pacing site includes steps of: securing first and second electromagnetic receiver coils at first and second positions, respectively, along a heart wall; collecting a set of non-paced heart wall motion data from each of the coils secured at the corresponding positions; applying cardiac pacing stimulation at at least one first pacing site; collecting a first set of paced heart wall motion data from each of the secured coils; comparing the non-paced heart wall motion data to the first set of paced heart wall motion data; and determining, based on the comparing, whether to maintain pacing at the at least one first cardiac pacing site or to apply pacing stimulation at a second pacing site for collection of a second set of paced heart wall motion data. The at least one first pacing site may include a right ventricular site and a left ventricular site.

  • Patent number: 6904315
    Abstract: An algorithm is implemented in a circuit for sensing P-waves in a pacemaker to ensure ventricular pacing synchronization with sensed atrial depolarization waves. VDD and VDDR pacing (atrial synchronized, ventricular inhibited pacing) are implemented via a single standard ventricular pacing lead (unipolar or bipolar) and preferably a subcutaneous electrode array (SEA). Specifically, an implanted ventricular lead provides ventricular pacing and ventricular sensing while the SEA enable atrial sensing, thus eliminating the need for an implanted atrial lead or a specialized single pass VDD lead. The algorithm manages the sensed cardiac waves to effect a desired pacing regimen based on the input from the single lead and SEA.

  • Patent number: 6236889
    Abstract: An apparatus and method for communicating acoustic telemetry data produced by an implantable medical device over a communication channel includes a signal generator, a modulator, and an acoustic transmitter each provided in the implantable medical device. The modulator modulates a carrier signal with an information signal representative of information acquired or produced by the implantable medical device so as to produce a modulated information signal. The modulated information signal may have a frequency content that is readily accommodated by a public exchange communication channel. The transmitter transmits the modulated information signal as an acoustic information signal in a form communicable over the communication channel. The acoustic information signal may constitute telephonic tones which are directly communicable over a conventional telephone connection.

  • Patent number: 6154675
    Abstract: An automatic, body-implantable medical device having at least two modes of operation is disclosed. The device is provided with circuitry for automatically detecting when the device has been implanted in a patient, so that the device can automatically switch from a first mode to a second mode of operation upon implantation. In one embodiment, the first mode is a power conserving mode in which one or more non-essential sub-systems of the device are disabled. Prior to detection of implant, at least two conditions of the device known to reflect whether the device has been implanted are monitored. After implant has been detected, situations in which power to the device is disrupted and then restored will cause the device to enter a predefined "power-on-reset" mode of operation. Prior to detection of implant, however, such conditions do not result in the device entering the power-on-reset mode, or this mode is reset.

  • Patent number: 5836989
    Abstract: An implantable medical device and corresponding system and method are disclosed having programmable operating functions for monitoring a patient condition or delivering a therapy. The device has a primary operating function and a trial operating function. Those functions are enabled or disabled in a time dependent manner to permit their comparison and evaluation in a patient. The device may include a telemetry transceiver for receiving external programmable sequences of operating instructions and for transmitting data externally to a programmer. The device may further include a memory for storing the sequence of operating instructions and for storing data related to the delivery of the therapy or the monitoring function.

  • Patent number: 5527347
    Abstract: There is provided a dual chamber pacemaker system and method for ventricular pacing to provide therapy for a patient with cardiomyopathy, this system being characterized by automatically adjusting the AV escape interval so that ventricular pace pulses are delivered at an AV delay which is optimized for HOCM and/or dialated cardiomyopathy therapy. The pacemaker system continually obtains and stores representations of a QRS wave characteristic such as duration, derived either directly from the QRS signal or from an FFRS signal, and compares duration data from one or more cycles to prior stored duration data. The system then adjusts the AV interval as a function of the duration comparison, and the direction of the last adjustment of AV escape interval. By this means, the AV escape interval is maintained at or just short of the onset of fusion, thereby automatically providing for optimally lengthened AV escape intervals consistent with full capture by the delivered ventricular pace pulse.

  • Patent number: 5441525
    Abstract: A rate-responsive cardiac pacemaker implements a novel scheme which detects incipient vasovagal syncope (or other episodes caused by a vasodepressive or cardioinhibitory disorder) when a) the heart rate drops below a programmable minimum size, and b) the rate after said drop is below a programmable maximum drop ending rate. The pacemaker implements a stability and intervention procedure upon the detection of an episode, in which it ignores transient drops in rate, and paces at a predetermined high rate if the drops are stable. The pacemaker then gradually reduces the pacing rate over a predetermined time to the pre-episodic level. A sleep disable feature disables the vasovagal syncope detection and therapy features during the patient's sleeping hours to reduce or eliminate false positive responses.
