  • Patent number: 11931580
    Abstract: An example of a method embodiment may include receiving a user programmable neural stimulation (NS) dose for an intermittent neural stimulation (INS) therapy, and delivering the INS therapy with the user programmable NS dose to an autonomic neural target of a patient. Delivering the INS therapy may include delivering NS bursts, and delivering the NS bursts may include delivering a number of NS pulses per cardiac cycle during a portion of the cardiac cycles and not delivering NS pulses during a remaining portion of the cardiac cycles. The method may further include sensing cardiac events within the cardiac cycles, and controlling delivery of the user programmable NS dose of INS therapy using the sensed cardiac events to time delivery of the number of NS pulses per cardiac cycle to provide the user programmable NS dose. The user programmable NS dose may determine the number of NS pulses per cardiac cycle.

  • Publication number: 20230149716
    Abstract: A neurostimulation system provides for capture verification and stimulation intensity adjustment to ensure effectiveness of vagus nerve stimulation in modulating one or more target functions in a patient. In various embodiments, stimulation is applied to the vagus nerve, and evoked responses are detected to verify that the stimulation captures the vagus nerve and to adjust one or more stimulation parameters that control the stimulation intensity.

  • Publication number: 20230122366
    Abstract: Systems and methods for managing heart failure are described. The system receives physiological information including a first HS signal corresponding to paced ventricular contractions and a second HS signal corresponding to intrinsic ventricular contractions. The system detects worsening heart failure (WHF) using the received physiological information. A signal analyzer circuit can generate a paced HS metric from the first HS signal and a sensed HS metric from the second HS signal, and determine a concordance indicator between the paced and the sensed HS metrics. In response to the detected WHF, the system can use the concordance indicator to generate a therapy adjustment indicator for adjusting electrostimulation therapy, or a worsening cardiac contractility indicator indicating the detected WHF is attributed to degrading myocardial contractility.

  • Publication number: 20230038324
    Abstract: Systems and methods for monitoring and treating patients with heart failure (HF) are discussed. The system may sense cardiac signals, and receives information about patient physiological or functional conditions. A stimulation parameter table that includes recommended values of atrioventricular delay (AVD) or other timing parameters may be created at a multitude of patient physiological or functional conditions. The system may periodically reassess patient physiological or functional conditions. A therapy programmer circuit may dynamically switch between left ventricular-only pacing and biventricular pacing, or switch between single site pacing and multisite pacing based on the patient condition. The therapy programmer circuit may adjust AVD and other timing parameters using the cardiac signal input and the stored stimulation parameter table. A HF therapy may be delivered according to the determined stimulation site, stimulation mode, and the stimulation timing.

  • Patent number: 11337646
    Abstract: An example of a system for providing a patient with pain management includes a pain monitoring circuit. The pain monitoring circuit may include parameter analyzer circuitry and pain score generator circuitry. The parameter analyzer circuitry may be configured to receive and analyze one or more timing parameters and one or more baroreflex parameters allowing for determination of baroreflex sensitivity (BRS) of the patient. The one or more timing parameters are indicative of time intervals during which values of the one or more baroreflex parameters are used to determine the BRS. The pain score generator circuitry may be configured to compute a pain score using an outcome of the analysis. The pain score is a function of the BRS during the time intervals and indicative of a degree of pain of the patient.

  • Patent number: 11207523
    Abstract: Systems and methods for pacing cardiac conductive tissue are described. An exemplary system includes an electrostimulation circuit that may generate HBP pulses to stimulate patient physiologic conduction pathway, such as a His bundle or a bundle branch. The system includes an arrhythmia detector to detect an atrial tachyarrhythmia (AT) with intermittent ventricular conduction. A control circuit may sense ventricular activation and, in response to the detected AT indication, determine or update a His-bundle pacing (HBP) configuration. The HBP may be recursively updated on a beat-by-beat basis using the sensed ventricular activation. The electrostimulation circuit may deliver HBP according to the determined or adjusted HBP configuration to regularize ventricular rate during AT.

  • Patent number: 11207528
    Abstract: Systems and methods for dynamically controlling HBP delivery based on patient AV conduction status are disclosed. An exemplary medical system includes an electrostimulation circuit to generate HBP pulses to stimulate a His bundle or a bundle branch of the heart. An AV conduction monitor circuit continuously or periodically assesses AV conduction status, and detects an indication of presence or absence of AV conduction abnormality. If an AV conduction abnormality is indicated, a control circuit may control the electrostimulation circuit to deliver the HBP pulses. Ventricular backup pacing may be delivered if HBP fails to capture and elicit ventricular activation. When the AV conduction become normal, the control circuit may withhold HBP delivery and promote patient intrinsic ventricular activation.
