Abstract
An example implantable medical device includes a stimulating lead includes receive one or more signals indicative of one or more physiologic parameters; deliver electrical therapy to stimulate a muscle wrapped around a heart via one or more electrodes of a stimulating lead; and adjust an amount of the electrical therapy delivered, via the stimulating electrodes, based on the one or more physiologic parameters.
Claims19
An implantable medical device comprising:
- a stimulating lead comprising one or more electrodes;
- an implantable cardioverter defibrillator (ICD) lead comprising:
- one or more pace/sense electrodes, and
- one or more defibrillation electrodes;
- and
- circuitry configured to:
- receive one or more signals indicative of one or more physiologic parameters;
- deliver electrical therapy to stimulate a muscle wrapped around a heart via the one or more electrodes of the stimulating lead;
- adjust an amount of the electrical therapy delivered, via the one or more electrodes of the stimulating lead, based on the one or more physiologic parameters;
- detect a tachyarrhythmia via one or more pace/sense electrodes of the ICD lead;
- and
- based on detecting the tachyarrhythmia:
- suspend, for a period of time, delivery of the electrical therapy to stimulate the muscle wrapped around the heart, and
- deliver an antitachyarrhythmia shock via the one or more defibrillation electrodes of the ICD lead during the period of time.
11 more elements
An implantable medical system comprising:
- an implantable medical device comprising:
- a housing;
- and
- circuitry within the housing, the circuitry configured to:
- receive one or more signals indicative of one or more physiologic parameters;
- and
- output a signal to cause electrical therapy to be delivered to stimulate a muscle wrapped around a heart based on the one or more physiologic parameters;
- and
- an implantable medical lead configured to be coupled to the medical device and to receive the signal output by the circuitry, the implantable medical lead comprising one or more electrodes to deliver the electrical therapy to stimulate the muscle wrapped around the heart in response to receiving the signal received from the circuitry;
- and
- an implantable cardioverter defibrillator (ICD) lead comprising one or more pace/sense electrodes and one or more defibrillation electrodes,
- wherein the circuitry is configured to:
- send a second signal to adjust an amount of the electrical therapy to be delivered, via the one or more electrodes of the implantable medical lead, based on the one or more physiologic parameters;
- detect a tachyarrhythmia based on a signal received via the one or more pace/sense electrodes of the ICD lead;
- based on the detection of the tachyarrhythmia:
- suspend, for a period of time, delivery of the electrical therapy to stimulate the muscle wrapped around the heart, and
- deliver an antitachyarrhythmia shock via the one or more defibrillation electrodes of the ICD lead during the period of time.
14 more elements
A method comprising:
- receiving, via circuitry, one or more signals indicative of one or more physiologic parameters;
- determining, via the circuitry, an amount of electrical therapy to deliver to stimulate a muscle wrapped around a heart of a patient based on the one or more physiologic parameters;
- delivering, via a stimulating lead, the determined amount of electrical therapy to stimulate the muscle wrapped around the heart of the patient;
- receiving, via one or more pace/sense electrodes of an implantable cardioverter defibrillator (ICD) lead, one or more sensed signals indicative of tachyarrhythmia;
- detecting, based on the one or more sensed signals indicative of tachyarrhythmia, a tachyarrhythmia;
- based on detecting the tachyarrhythmia:
- suspending, for a period of time, delivery of the electrical therapy to stimulate the muscle wrapped around the heart, and
- delivering, via one or more defibrillation electrodes of the ICD lead, an antitachyarrhythmia shock during the period of time.
