Medtronic Receives CE Mark for Pacemakers Designed for Conduction-System Pacing

Posted on by Posted in Bradycardia, Cardiac Pacing, Cardiac Stimulation (other), Heart Failure (CHF), Medtronic

Medtronic announced on October 19, 2026, that its Vitalis pacemaker portfolio has received CE marking. The family includes ReSyncra CSP, Restoria CSP, Refina CSP, Effectra, and Confirma, with dedicated conduction-system pacing features available in selected models. ReSyncra CSP provides an option for patients indicated for conventional biventricular pacing in whom effective cardiac resynchronization therapy cannot be achieved. Its AdaptivCSP algorithm automatically adjusts pacing timing to support ventricular synchronization.

The notable development is the integration of CSP-specific control and monitoring into the pulse generator. ReSyncra CSP, Restoria CSP, and Refina CSP incorporate CSP MVP programming options and a CSP Morphology Monitor for following therapy during remote and office evaluations. These capabilities complement Medtronic’s existing SelectSecure Model 3830 lead and CSP delivery tools, extending support beyond lead placement to ongoing therapy management.

Berlin Heals recently published results of its open-label randomized controlled trial of its C-MIC device.  The study enrolled 70 ambulatory patients (32 C-MIC, 33 control) with non-ischaemic dilated cardiomyopathy with left ventricular ejection fraction (LVEF) of 25%to 35% and New York Heart Association (NYHA) class III–IV.

According to the June 2025 abstract:

“At 6 months, treatment with C-MIC versus control improved LVEF (mean difference: 5.1%; 95% confidence interval [CI] 3.1–7.1%, p < 0.001). The proportions of patients with improvement in at least one NYHA class (risk difference: 68.9%; 95% CI 50.6–87.2, p < 0.001), an increase of ≥5 points in KCCQ-OSS (risk difference: 60.0%; 95% CI 42.3–77.6, p < 0.001), and an increase of ≥30%in 6MWD (risk difference: 38.3%; 95% CI 14.4–62.2) were substantially higher in the device versus control group(p < 0.002).”

In June, Berlin Heals also reported on the 2-year follow-up of patients from the initial C-MIC pilot study who were alive at 6 month as follows:

“Of the 10 patients enrolled in the initial study, 7 were enrolled in follow-up (mean age 52.4 ± 7.6 years, NYHA Class III and mean LVEF 31.7 ± 3.7%). No device-related adverse events occurred. One non-cardiac, non-device related death was reported at 18 months. Improvement in LVEF of 11.60% [95% confidence interval (CI): 5.64–17.56, P < 0.001] from baseline to 6 months was maintained at 2 years post-C-MIC deactivation, with a sustained increase of 12.56% from baseline (95% CI: 4.67–20.45, P = 0.002). Similarly, the 6 min walk distance improved by 206.35 m at 6 months (95% CI: 161.32–251.39, P < 0.0001) and remained at 191 m above baseline at 2 years (95% CI: 131.83–250.99, P < 0.0001). Improvements in NYHA functional class and SF-36 quality-of-life scores observed at 6 months were also preserved throughout the 2 year follow-up. One patient required C-MIC reactivation.”

FDA Approves breakthrough Optimizer® Smart System Delivering CCM™ Therapy for Treatment of Heart Failure

Posted on by Posted in Cardiac Contractility Modulation, Cardiac Stimulation (other), David Prutchi's Portfolio, Dr. Shlomo Ben-Haim (Medinvest), Heart Failure (CHF), Impulse Dynamics

I have led the development of devices to deliver CCM™ therapy from the very beginning, so it is with great pleasure and pride that I share with you the exciting news that Impulse Dynamics just received approval from the United States Food and Drug Administration (FDA) for our Optimizer® Smart System for heart failure patients!  An official FDA announcement was made through the publication of a press release that you can find here: https://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm634103.htm.

Impulse Dynamics’ press release is as follows:

Impulse Dynamics receives FDA approval for breakthrough Optimizer® Smart System delivering CCM™ therapy for treatment of heart failure

Orangeburg, New York, March 21, 2019 – Impulse Dynamics, developer of the implantable Optimizer® Smart System for delivering CCM™ therapy, announced today that it has received approval from the United States Food and Drug Administration for its first-in-class Optimizer Smart System.

Designed to address a significant unmet medical need in heart failure, the Optimizer Smart System received Breakthrough Device designation from the FDA in 2015. It was the first breakthrough device to go before the Circulatory System Devices Panel of the FDA’s Medical Devices Advisory Committee, on Dec. 4, 2018, receiving a 12-0 vote on the benefit-to-risk ratio of the device.

“With the FDA’s approval of the Optimizer System for the delivery of CCM, we finally have available in the US an effective device-based therapy for advanced heart failure patients with mildly to moderately reduced left ventricular ejection fractions who are not eligible for CRT,” said Professor William T. Abraham, MD, Professor of Medicine, Physiology, and Cell Biology, and College of Medicine Distinguished Professor at the Ohio State University Wexner Medical Center. “The Optimizer System, along with guideline-directed medical therapies, can improve the lives of many heart failure patients in the US who previously did not have access to this therapy. As such, it represents a real game-changer for these patients.”

The Optimizer Smart System is the first and only CCM device approved by the FDA to improve 6-minute hall walk distance, quality of life and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for CRT, and have an LVEF ranging from 25% to 45%. Only 30 percent of moderate to severe chronic heart failure patients are candidates for CRT, which historically has left 70 percent of patients with few options to help them manage their disease.

“FDA approval is the culmination of many years of clinical development for this disruptive technology, addressing a significant unmet need in today’s heart failure treatment paradigm,” commented Dr. Daniel Burkhoff, Impulse Dynamics’ Medical Advisor. “We continue to develop the technology with ongoing clinical trials designed to evaluate CCM therapy in additional heart failure populations.”

CCM is a unique electrical pulse delivered during the absolute refractory period, which is just after the heart contracts. In contrast to a pacemaker or defibrillator, CCM works by modulating the strength of the heart muscle contraction rather than the rhythm.

Dr. Simos Kedikoglou, Impulse Dynamics’ CEO, announced that the Company will launch the device in the US later this year.  “We are extremely excited that the Optimizer Smart System with CCM therapy is now available in the United States,” he said. “We look forward to growing our commercial presence in the US and globally.”

Implantable devices for the treatment of heart failure, David Prutchi, PhD

 

A position paper was published yesterday by the European Heart Rhythm Association reporting on the performance of new devices for the treatment of heart failure (HF). The report has been endorsed by the Heart Failure Association.

The abstract for the paper titled “New devices in heart failure: an European Heart Rhythm Association report” reads:

 Several new devices for the treatment of heart failure (HF) patients have been introduced and are increasingly used in clinical practice or are under clinical evaluation in either observational and/or randomized clinical trials. These devices include cardiac contractility modulation, spinal cord stimulation, carotid sinus nerve stimulation, cervical vagal stimulation, intracardiac atrioventricular nodal vagal stimulation, and implantable hemodynamic monitoring devices. This task force believes that an overview on these technologies is important. Special focus is given to patients with HF New York Heart Association Classes III and IV and narrow QRS complex, who represent the largest group in HF compared with patients with wide QRS complex. An overview on potential device options in addition to optimal medical therapy will be helpful for all physicians treating HF patients.

The report places special focus to patients with HF New York Heart Association (NYHA) Classes III and IV and narrow QRS complex, who represent the largest group in HF compared with patients with wide QRS complex (who are candidates for treatment with cardiac resynchronization therapy – CRT).

Impulse Dynamics Launches CE-Marked OPTIMIZER IVs System for the Treatment of Heart Failure

Posted on by Posted in Cardiac Stimulation (other), Dr. Shlomo Ben-Haim (Medinvest), Heart Failure (CHF), Impulse Dynamics, My Portfolio

Impulse Dynamics OPTIMIZER IVs IPG for treatment of heart failure

Impulse Dynamics (yes, the company for which I work) launched its new, CE-marked OPTIMIZER™ IVs implantable device for the treatment of heart failure at the 79th Annual Meeting of the German Cardiac Society (Mannheim, Germany, 3–6 April 2013).

The OPTIMIZER™ IVs Implantable Pulse Generator (IPG) is a programmable telemetric device intended to treat moderate to severe heart failure resulting from left ventricular dysfunction by monitoring intrinsic cardiac electrical activity and delivering Cardiac Contractility Modulation (CCM) signals during the ventricular absolute refractory period.  These electrical signals are intended to influence myocardial properties in patients, thereby reducing their symptoms and improving quality of life and exercise tolerance.

The OPTIMIZER™ IVs IPG was designed to deliver CCM signals during the ventricular absolute refractory period in synchrony with locally-sensed electrical activity. The microprocessor controlled implantable device comprises intracardiac electrogram sensing circuits, control logic, communications circuitry, and circuitry to generate the CCM signals.  Electrogram signals are detected from and CCM signals are delivered to the heart using standard chronically-implantable bipolar pacing leads.  The implant procedure is similar to implantation procedures for other cardiac rhythm management devices.
