What Thorasys does

Thorasys Thoracic Medical Systems Inc. is a privately held respiratory medical device company founded in 2007 and headquartered in Montreal, Quebec, with a wholly-owned European subsidiary, THORASYS Europe GmbH, in Teningen, Germany. The company develops and commercializes the Airwave Oscillometry System (AOS®), a respiratory diagnostics platform built on the Forced Oscillation Technique and centered on its patented breathe-through vibrating mesh oscillator technology. Its product portfolio consists of two handheld oscillometry devices — the tremoflo® C-100 and the second-generation tremoflo® C2 — supported by a recurring-consumables ecosystem that includes clearflo™ F-100 bacterial/viral filters, single-use nose clips, calibration test loads, a support arm, and carrying cases.

The C-100 delivers a 20-second measurement with three repetitions, while the C2 introduces sparse waveform technology with adult and pediatric waveform sets (AOS 5-37 and AOS 7-41 respectively), a 500g portable form factor, color-coded gauge outputs, and PDF/CSV report generation. Both devices superimpose gentle oscillatory waves on a patient's quiet tidal breathing to quantify large and small airway function, bronchodilator response, and peripheral obstruction, addressing patient populations — particularly children, elderly patients, and others unable to perform forced spirometry maneuvers — that are underserved by conventional spirometers.

Thorasys monetizes through a hardware sales model (devices plus consumables), with pricing handled on a quote basis rather than publicly disclosed. Go-to-market is bifurcated: healthcare institutions (hospitals, clinics, physician practices) purchase directly through [email protected], while clinical trials demand is served through two specialized channel partners — Clario (Americas) and Vitalograph Clinical Trials (USA). The company holds ISO 13485 and ISO/IEC 27001 certifications, maintains REACH compliance for the EU market on the C2, and operates with a very small team of 1–10 employees.

Core offering

Thorasys manufactures and sells the proprietary Airwave Oscillometry System (AOS®), consisting of the tremoflo® C-100 and tremoflo® C2 handheld respiratory diagnostic devices. These devices use the patented breathe-through vibrating mesh technology and Forced Oscillation Technique to non-invasively measure large and small airway function in patients who cannot perform traditional forced breathing maneuvers. The portfolio also includes accessories and consumables such as test loads, nose clips, carrying cases, support arms, and clearflo™ F-100 bacterial/viral filters.

Product overview

Thorasys offers the proprietary Airwave Oscillometry System (AOS®), a respiratory diagnostics technology platform comprising two oscillometry devices: the tremoflo® C2 (second-generation, 500g portable device) and the tremoflo® C-100 (classic handheld model). Both devices use the patented breathe-through vibrating mesh technology with pseudo-random noise oscillometry to assess respiratory function. The product portfolio is complemented by compatible accessories including test loads for calibration, nose clips, carrying cases, support arms, and clearflo™ F-100 bacterial/viral filters.

Direct peers

• Cosmed: Cosmed is a global manufacturer of cardiopulmonary diagnostic equipment (spirometry, PFT, metabolic carts) used in clinical and research settings. It overlaps with Thorasys in respiratory function assessment and clinical-trial applications.
• Vitalograph: Vitalograph is a leading spirometry and respiratory diagnostics company that also serves as a clinical-trials distributor for Thorasys. It competes with the tremoflo devices in PFT and oscillometry applications while partnering in the trial channel, making it the most directly comparable peer.
• ndd Medical Technologies: ndd manufactures the EasyOne line of portable spirometers and PFT devices used in hospitals, primary care, and clinical trials. Its portable, easy-to-use lung-function devices compete head-to-head with Thorasys's tremoflo in the same clinical-use cases.
• MGC Diagnostics (now part of Caire Diagnostics): MGC Diagnostics / Caire Diagnostics produces pulmonary function testing systems for hospitals and clinical research. It targets the same PFT use cases as Thorasys's tremoflo devices, especially in pulmonary labs and clinical trial settings.

Others

• Clario: Clario is a major clinical-trial endpoint and respiratory assessment CRO that distributes Thorasys's tremoflo for clinical trials. It is a strategic channel partner and ecosystem participant rather than a direct product competitor, but is materially connected to Thorasys's clinical-trials go-to-market.

Broad incumbents

• Vyaire Medical: Vyaire Medical is a broad respiratory care incumbent offering spirometry, ventilation, and airway management products. While not a specialist in oscillometry, it competes with Thorasys in clinical PFT and pulmonary diagnostics as part of a much larger portfolio.
• Schiller AG: Schiller manufactures a wide range of cardiopulmonary diagnostics including spirometry and PFT platforms used in clinical settings. It competes with Thorasys for hospital and clinical respiratory diagnostics customers within a broader cardiology/cardio-respiratory portfolio.
• BD (CareFusion legacy): Becton Dickinson (BD) inherited the CareFusion Vmax/PFT pulmonary function business and is a large-incumbent supplier of hospital PFT equipment. It competes with Thorasys in respiratory diagnostics as part of a much broader medtech portfolio.

Regional players

• CHEST M.I. (Chestgraph): CHEST M.I. is a Japanese pulmonology-focused PFT and oscillometry manufacturer serving primarily the Japanese and broader Asian markets. Its Hi-Force Oscillometry devices compete with Thorasys in the APAC region where Thorasys also has tech support presence.

Emerging players

• Bertin Medical / Coriolis Group (Second Génération / Sages): Bertin Medical and its Coriolis brand produce respiratory measurement instruments including oscillometry systems. They are a niche European peer competing in the same specialized respiratory diagnostics category where Thorasys operates.
