What Medsteer does

Medsteer SAS is a private French medical technology company specializing in closed-loop anesthesia drug delivery systems. The company's flagship product, EasyTIVA, is a patented platform that automates the dosing of Propofol and Remifentanil during surgical procedures by using real-time EEG-based depth-of-anesthesia indices (BIS and spectral M-Entropy) as feedback to a proprietary control algorithm. EasyTIVA supports both induction and regulation phases and is designed for use across all patient types and all surgical procedures, validated across 25+ multicenter clinical trials and more than 15,000 patient inclusions since 2006 in 9 countries.

Medsteer operates with a small team (11-50 employees) under a dual-channel go-to-market model: direct sales to hospitals and surgical centers for EasyTIVA platform deployment, and technology licensing/integration partnerships with pharmaceutical and medical device companies seeking to embed EEG-guided closed-loop control into their own platforms. The company's technology integrates with third-party brain monitoring systems from Medtronic and GE Healthcare and uses standard syringe pumps within a closed-loop architecture. Pricing is not publicly disclosed and is likely quotation-based for institutional procurement.

In January 2026, Medsteer entered a strategic exclusive collaboration with Cyclerion Therapeutics to integrate its EEG-guided closed-loop control technology into Cyclerion's closed-loop anesthetic platform for CYC-126, an investigational therapy for treatment-resistant depression — a notable expansion of the core technology into psychiatric indications beyond surgical anesthesia. The company is also developing a reference design device as a next-generation tool for anesthesiologists, signaling a transition from a pure technology licensor toward a hardware-enabled medical device company.

Core offering

Medsteer sells the patented EasyTIVA technology platform, a closed-loop Total Intravenous Anesthesia (TIVA) system that fully automates the induction and regulation of Propofol and Remifentanil dosing during surgery. The platform uses a proprietary EEG-guided algorithm that ingests real-time depth-of-anesthesia index values (0–100) from compatible brain monitors and non-invasive forehead sensors, then drives standard syringe pumps in a closed-loop architecture to deliver precise drug amounts. The technology is targeted at hospitals, surgical centers, and anesthesiologists, and is also being licensed for integration into pharmaceutical platforms (e.g., Cyclerion's CYC-126).

Product overview

Medsteer is a technology provider in closed-loop anesthesia drug delivery systems. The company's primary product is EasyTIVA, a patented technology platform that automates Propofol and Remifentanil dosing guided by real-time EEG monitoring. EasyTIVA represents the core platform, while the company is also developing a reference design device as a next-generation tool for anesthesiologists. The technology has been validated through over 25 clinical trials with more than 15,000 patient inclusions since 2006.

Broad incumbents

• GE HealthCare: GE Healthcare is a main supplier of brain monitoring systems compatible with EasyTIVA and offers comprehensive anesthesia delivery and patient monitoring solutions, making it both a partner and a broad incumbent in the same OR ecosystem.
• Medtronic: Medtronic supplies the BIS brain monitoring system used as input to EasyTIVA, but also markets broader perioperative and patient monitoring portfolios, positioning it as both a partner and a potential full-stack competitor in closed-loop OR automation.
• Drägerwerk: Dräger is a leading global supplier of anesthesia workstations, integrated patient monitoring, and OR IT, and could bundle competing closed-loop capabilities into its Perseus and similar anesthesia platforms over time.
• Edwards Lifesciences: Edwards provides hemodynamic monitoring used alongside anesthesia delivery in the OR and has explored closed-loop fluid and drug administration concepts, making it an adjacent incumbent with overlapping clinical use cases.
• Koninklijke Philips: Philips provides perioperative patient monitoring and integrated OR solutions overlapping with Medsteer's clinical environment, and has been investing in decision-support and AI-driven anesthesia analytics that could converge with closed-loop dosing.
• Becton Dickinson: BD offers infusion and medication management technologies used in surgical and ICU sedation settings, and competes in adjacent closed-loop and smart-pump categories relevant to Medsteer's dosing automation value proposition.

Direct peers

• Masimo: Masimo's SedLine EEG-based depth-of-anesthesia monitor competes directly with the Medtronic/GE monitors that EasyTIVA relies on, and Masimo increasingly integrates analytics into its own OR platform, making it the closest adjacent competitor in EEG-guided anesthesia.
• ICU Medical: ICU Medical (Smiths Medical infusion portfolio) supplies syringe pumps and infusion systems that are central to closed-loop drug delivery architectures like EasyTIVA, and is a direct adjacency in the closed-loop anesthesia technology stack.

Emerging players

• Mindray: Mindray provides patient monitoring and anesthesia delivery systems including EEG-based depth-of-anesthesia modules, and is rapidly expanding in emerging markets, representing a growing lower-cost competitor to EasyTIVA's positioning.
• Sedana Medical: Sedana Medical focuses on inhaled sedation in the ICU setting, an adjacent clinical use case to Medsteer's closed-loop IV anesthesia and sedation platform, with overlapping anesthesiology and critical care customer segments.
