Dymedix Diagnostics

What Dymedix Diagnostics does

Dymedix Diagnostics, Inc. is a privately held, Shoreview, Minnesota-based medical device manufacturer founded in 2001 by engineer Peter Staz, the discoverer of polyvinylidene fluoride (PVDF) as a physiological-sensing material. The company's entire portfolio is built on a patented PVDF sensor platform: a polarized plastic film that generates its own electrical signal when stimulated by temperature, pressure, vibration, or movement, with a 5-millisecond response time. Products span airflow sensors (TriplePlay), respiratory effort belts (FastTrack, PerfectFit 3D/2, SnuggleFit), surface electrodes (FlexPro, Precision Gold EEG, Dual EMG Patch, TripleChin, AccuSnore, XM Extremity Movement), and two PSG setup kits (pre-configured CompletePlus and configurable MyCustomPSG), with a dedicated Lullaby sub-brand serving neonatal, infant, and pediatric populations. All products are FDA 510(k) cleared, AASM-compliant, and JCAHO-aligned, and are validated to integrate with every major polysomnography (PSG) platform—Alice, Embla, Grael, Cadwell, Nihon Kohden, SomnoStar, and Xltek.

The business model is hardware sales of consumable and reusable sensors, sold as individual units and as kits, in both disposable and reusable formats. Pricing is primarily quote-based through Dymedix-employed clinical specialists and a network of authorized distributors accessible via the company's distributor locator; reference pricing of approximately $250 per bed per year for airflow sensors compares to roughly $1,038 per bed per year for incumbent thermistor-plus-cannula-plus-snore-sensor combinations. Go-to-market is enterprise/distributor-driven (clinical sleep labs and sleep disorder centers as primary buyers), supplemented by content marketing, YouTube product demonstrations, conference presence (e.g., SLEEP 2022), and PR distribution through PRWeb and EIN Presswire. Customer segments are vertical rather than horizontal: clinical sleep medicine (PSG), pediatric sleep medicine (neonates through adolescents), and home sleep apnea testing/screening.

The company operates with 11–50 employees under CEO Jim Moore, with three VP-level executives leading sales and business development (John Bozich, ex-Cadwell), product development (Todd Eiken, RPSGT), and business development and marketing (Troy Pridgeon). Recent strategic activity has been product-led rather than capital-led: Lullaby pediatric line (2019), Dymedix Disposables (2020, COVID-driven), CompletePlus Disposable PSG Setup Kit (2022), FlexPro Biopotential Electrodes standalone (2025), and MyCustomPSG Kit (2025). No venture funding rounds, institutional investors, M&A activity, or subsidiaries have been disclosed, and the company appears to remain founder-controlled and privately financed.

Core offering

Dymedix Diagnostics designs and manufactures sleep diagnostic sensors and electrodes built on its patented Polyvinylidene Fluoride (PVDF) technology for the clinical sleep medicine community. The company sells airflow sensors, respiratory effort belts, EEG/EMG electrodes, snore sensors, and PSG setup kits in disposable and reusable versions, plus the Lullaby pediatric sub-brand for neonatal, infant, and child sleep testing. All products are FDA-cleared, AASM-compliant, and compatible with major polysomnography (PSG) systems.

Product overview

Dymedix Diagnostics offers a comprehensive portfolio of sleep diagnostic sensors and electrodes based on its proprietary patented PVDF (Polyvinylidene Fluoride) technology. The product portfolio is organized around core sensor categories — TriplePlay airflow sensors (with FM filtration modules for signal processing), respiratory effort belts (FastTrack, PerfectFit 3D, PerfectFit 2, SnuggleFit), and surface electrodes (FlexPro, Precision Gold EEG, Dual EMG Patch, AccuSnore snore sensor, XM extremity movement sensor, TripleChin) — plus two kit products: the CompletePlus Disposable PSG Setup Kit (pre-configured) and the MyCustomPSG Kit (fully customizable). A dedicated sub-brand, Lullaby, serves the neonatal/infant/pediatric segment with size-appropriate versions of airflow sensors, effort belts, the iFM infant filtration module, and SnuggleFit belts. All products are offered in both disposable and reusable options. Sensors are compatible with all major PSG systems including Alice, Embla, Grael, Cadwell, Nihon Kohden, SomnoStar, and Xltek.
