What StimCardio Medical (formerly CardiaCare) does

StimCardio Medical (formerly CardiaCare) is a clinical-stage private medical device company developing a non-invasive wearable neuromodulation platform for the management of atrial fibrillation. Founded in 2015 in Israel by Amos Ziv and rebranded to StimCardio in 2025, the company is headquartered in Los Angeles with engineering and R&D operations in Austin, Texas, and scientific operations in Ness Ziona, Israel. The target patient population comprises individuals with paroxysmal atrial fibrillation and post-ablation patients experiencing recurrence, segments underserved by antiarrhythmic drugs, invasive ablation procedures, and cardioversion.

The company's lead asset is Rhyvive, a wrist-worn wearable integrating ECG and optical sensors with embedded stimulation electrodes, paired with a companion mobile application. Rhyvive delivers personalized median-vagus nerve stimulation (mVNS) at the wrist, modulating autonomic nervous system activity and cardiac rhythm. Physiological data is transmitted to the StimCardio Health Cloud, a machine learning-enabled platform that performs longitudinal pattern analysis, arrhythmia precursor detection, and adaptive closed-loop personalization, complemented by a provider-facing clinical dashboard for electrophysiologists. The company has completed a feasibility study (n=10), a randomized sham-controlled pilot (n=31), and a mechanism-of-action study (n=25), with pivotal trial preparation underway and FDA clearance targeted for 2027.

StimCardio is pre-revenue with no commercially approved products. Approximately $25M in disclosed funding has been raised across a September 2023 seed extension (Solardis Health Ventures) and a 2025 Series A led by Metis MedTech. The planned commercial model is a physician-prescribed at-home deployment of Rhyvive, potentially combined with subscription-based cloud analytics and remote patient monitoring. Distribution is currently confined to clinical trial participants; commercial launch is contingent on FDA clearance and will be anchored through KOL relationships, scientific conferences, and accelerator partnerships including MedTech Innovator and HeartX.

Core offering

StimCardio Medical is developing a non-invasive, wearable neuromodulation platform centered on the Rhyvive wrist-worn device, which delivers personalized median-vagus nerve stimulation (mVNS) while continuously monitoring cardiac and autonomic signals via integrated ECG and optical sensors. Data is transmitted to the StimCardio Health Cloud, a cloud-based platform using machine learning for pattern analysis, personalization, and adaptive closed-loop therapy. The platform includes a patient-facing mobile application and a provider-facing clinical dashboard, targeting atrial fibrillation management with FDA clearance targeted for 2027.

Product overview

StimCardio Medical offers a unified therapeutic platform centered on the Rhyvive wrist-worn wearable, which delivers personalized median-vagus neuromodulation (mVNS) while continuously monitoring cardiac and autonomic signals via integrated ECG and optical sensors. Physiological data flows to the StimCardio Health Cloud, a cloud-based platform that uses machine learning to enable pattern analysis, personalization, and adaptive closed-loop behavior. The ecosystem includes a patient-facing mobile application for therapy management and symptom tracking, and a provider-facing clinical dashboard enabling remote patient monitoring. This closed-loop architecture enables the system to adapt neuromodulation parameters based on individual physiological patterns over time.

Expansion highlights6 records

Direct peers

• Electrocore: Developer of non-invasive vagus nerve stimulation (nVNS) devices including gammaCore for headache and exploratory cardiac/AF applications. Closely comparable to StimCardio as a non-invasive peripheral neuromodulation platform targeting autonomic pathways, though Electrocore is more clinically established in migraine and earlier in cardiac indications.
• CVRx: Developer of Barostim, an implantable neuromodulation device FDA-approved for heart failure. Direct peer in cardiovascular neuromodulation with cleared regulatory pathway and commercial-stage revenues; differs from StimCardio in invasiveness (implant vs. wearable) and primary indication (HF vs. AF).

Emerging players

• iRhythm Technologies: Commercial-stage digital cardiac monitoring company (Zio long-term continuous ECG patch) with AI-powered arrhythmia detection. Comparable to StimCardio's wearable sensing + cloud analytics architecture and serves the same electrophysiology prescribing channel, though iRhythm is diagnostic-only with no therapeutic neuromodulation.
• AliveCor: Maker of KardiaMobile, a consumer/clinical-grade single-lead ECG device with AI-based AF detection and remote monitoring. Comparable ECG-and-cloud analytics overlap with StimCardio's Rhyvive, though AliveCor is diagnostic and consumer-direct rather than a prescribed therapeutic.
• Eko Health: AI-powered digital stethoscope and cardiac monitoring platform with FDA-cleared ECG and AF detection algorithms. Comparable in combining wearable ECG sensors with cloud-based ML arrhythmia analysis, though Eko focuses on point-of-care auscultation rather than chronic wearable therapy.
• Inspire Medical Systems: Commercial-stage implantable neuromodulation company (hypoglossal nerve stimulation for obstructive sleep apnea) that established a precedent for neuromodulation category creation and payer coverage. Useful analog for StimCardio's path from novel neuromodulation to commercial reimbursement, though modality and indication differ.

Broad incumbents

• Boston Scientific: Acquired Farapulse (pulsed-field ablation) for $800M+ in 2021 and operates a broad cardiac rhythm management franchise. The dominant incumbent competing for AF treatment dollars; StimCardio's neuromodulation approach is positioned as adjuvant to or alternative for Boston Scientific's ablation portfolio.
• AtriCure: Commercial-stage surgical and catheter ablation company focused on atrial fibrillation, including the Isolator Synergy and cryoSPHERE devices. Direct incumbent in the AF ablation space StimCardio targets as an adjuvant/non-invasive alternative.
• Medtronic: Largest cardiac rhythm management incumbent with pacemakers, ICDs, CRTs, and the Arctic Front cryoablation franchise. Sets the standard-of-care benchmark that any wearable neuromodulation for AF must outperform on cost, convenience, or patient selection.

Regional players

• Axonics: Developer of miniaturized, long-lived sacral neuromodulation implants for incontinence. Comparable as a pure-play neuromodulation company with successful commercialization, FDA-cleared platform, and strong reimbursement coverage — adjacent therapeutic area but analogous commercial pathway.
