    摘要: A method and device for treating myocardial ischemia in which an implantable pulse generator delivers electrical stimulation to electrodes disposed near a coronary artery. The stimulation parameters may be adjusted to produce vasodilation and/or vasoconstriction of the artery. The device may be configured to operate in a vasodilation and/or vasoconstriction mode in accordance with specified entry and exit conditions.

    摘要: Systems and methods to monitor cardiac mechanical vibrations using information indicative of lead motion are described. In an example, a system including an implantable medical device can include an excitation circuit configured to provide a non-tissue stimulating, non-therapeutic electrical excitation signal to a portion of an implantable lead. A receiver circuit can be configured to obtain information indicative of a mechanical vibration of the implantable lead due at least in part to one or more of an impact of at least a portion of the heart to the implantable lead, or friction contact between the implantable lead and cardiac tissue. The system can include a processor circuit configured to determine one or more of a lead mechanical status, or information indicative of valvular activity using the information indicative of the mechanical vibration of the implantable lead.

    摘要: An implantable neural stimulation system includes an implantable medical device having a neural stimulation circuit and at least one implantable lead configured to allow one or more stimulation electrodes to be placed in one or more lymphatic vessels of a patient, such as the patient's thoracic duct and/or vessels branching from the thoracic duct. Neural stimulation pulses are delivered from the implantable medical device to one or more target regions adjacent to the thoracic duct or the vessels branching from the thoracic duct through the one or more stimulation electrodes.

    摘要: A device and method for delivering electrical stimulation to the heart in order to improve cardiac function in heart failure patients. The stimulation is delivered as high-output pacing in which the stimulation is excitatory and also of sufficient energy to augment myocardial contractility. In order to provide a consistent hemodynamic response, the high-output pacing is optimized by delivering it using different parameter sets, evaluating the hemodynamic response thereto as reflected by one or more measured physiological variables, and selecting the parameter set with the best hemodynamic response.

    摘要: Acoustic energy is delivered to innervated vascular that contributes to renal sympathetic nerve activity, such as innervated tissue of the renal artery and abdominal aorta. Focused acoustic energy is delivered via an intravascular device of sufficient power to ablate innervated renal or aortal tissue. Focused acoustic energy may be delivered via an intravascular or extracorporeal device to image and locate target innervated renal or aortal tissue. Intravascular, extravascular, or transvascular focused ultrasound devices provide for high precision denervation of innervated vascular to terminate renal sympathetic nerve activity.
