  • Patent number: 10835133
    Abstract: A method for monitoring a cardiovascular pressure in a patient may include storing, in a memory of an implantable medical device system and in association with each one or more different patient postures, a respective offset value for the cardiovascular pressure of the patient. The one or more offset values may be determined based on a distance between an implantable pressure sensing device and an anatomical structure of the patient, a location of the implantable pressure sensing device within the patient, or one or more dimensions an anatomical structure of the patient. The method further includes determining a measured value of the cardiovascular pressure and a posture of the patient when the value of the cardiovascular pressure was measured, selecting a stored offset value associated with the current patient posture, and determining an adjusted cardiovascular pressure value based on the selected offset value and the measured cardiovascular pressure value.

  • Publication number: 20200306529
    Abstract: An implantable medical device delivery system includes a delivery catheter including an elongated body with a first portion defining a first lumen and a second portion defining a second lumen. An angle is defined between a first axis and a second axis defined by the first and second portions, respectively. The second axis points toward the left ventricular (LV) apex of the patient's heart when the first axis points into the CS. The first portion or an elongated element may extend into the CS to anchor the delivery catheter to the orientation of the CS.

  • Publication number: 20200288989
    Abstract: A method for monitoring a cardiovascular pressure in a patient includes measuring, by pressure sensing circuitry of an implantable pressure sensing device, the cardiovascular pressure of the patient. The method further includes transmitting, via wireless communication circuitry of the implantable pressure sensing device, the measured cardiovascular pressure to another device. The method further includes determining, by processing circuitry of the other device, whether a posture of the patient at a time of the measured cardiovascular pressure was a target posture for cardiovascular pressure measurements. The method further includes determining, by the processing circuitry of the other device, whether to store or discard the transmitted cardiovascular pressure based on determining whether the posture was the target posture.

  • Publication number: 20190374781
    Abstract: An implantable medical device system and method for delivering cardiac resynchronization therapy (CRT) pacing that includes determining capture associated with the delivered CRT pacing is ineffective in response to the delivered CRT pacing. A reason for capture being ineffective is determined and a safety margin is adjusted if the determined reason for capture being ineffective is loss of capture and a left ventricle (LV) pre-excitation is adjusted if the determined reason for capture being ineffective is delayed LV depolarization. Monitoring for a change in effective cardiac resynchronization therapy is used to confirm that the adjustment of the CRT pacing was effective in resolving the ineffective capture.

  • Publication number: 20190336767
    Abstract: An implantable cardiac rhythm management medical device is configured to switch from a first operating mode to a second, ventricular assist device operating mode for detecting cardiac arrhythmias and controlling delivery of anti-arrhythmia therapy during the ventricular assist device operating mode. The implantable medical device may receive a command from another medical device indicating co-implantation of a ventricular assist device with the implantable medical device in a patient and switch from the first mode of operating to the second mode of operating in response to receiving the command. Switching from the first mode to the second mode may include adjusting at least one control parameter used for controlling an electrical stimulation therapy deliverable by the implantable cardiac rhythm management medical device.

  • Patent number: 10376159
    Abstract: Systems, devices disclosed provide example methods comprising determining that a triggering event has occurred based on statuses for a set of physiological parameters associated with the patient, the physiological parameters indicative of the patient engaging in a patient initiated physical activity, generating a trigger output signal in response to the determination that the triggering event has occurred, wirelessly transmitting the trigger output signal to a pressure sensing device implanted in a vessel of the patient, triggering, based on receiving the trigger output signal, the pressure sensing device to sense a cardiovascular pressure of the patient; and transmitting, by the pressure sensing device, a wireless signal comprising data corresponding to the sensed cardiovascular pressure of the patient.

  • Publication number: 20170164845
    Abstract: An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation assembly that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation assembly is formed having at least one flexible asymmetric connector where each fixation member includes a plurality of loops, wherein a first loop of the plurality of loops has a maximum pitch that is different from a maximum pitch of a second loop of the plurality of loops. The attachment of the housing and the fixation assembly includes providing a tubular member that is welded to the housing and crimped over a section of the fixation assembly.

  • Patent number: 9101772
    Abstract: A method of stimulation therapy and an apparatus for providing the therapy which addresses cardiac dysfunction including heart failure. The therapy employs atrial pacing pulses delivered to a heart after the atrial refractory period and timed so that they will not cause a ventricular contraction. These atrial pacing are timed to achieve beneficial effects on myocardial mechanics (efficacy) while maintaining an extremely low level of risk of arrhythmia induction. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.
