Providing a Foundational Quality Management System (QMS) for Commercialization

Certificate issued by GMED, an EU MDR notified body, following the positive certification decision previously announced
ISO 13485 certification supports ongoing MDR conformity assessment activities for the Lumee Oxygen Platform and represents an important milestone toward MDR certification and CE marking.

BERKELEY, Calif., Oct. 15, 2026 (GLOBE NEWSWIRE) -- Profusa, Inc. (NASDAQ:PFSA) ("Profusa" or the "Company"), a digital health company pioneering next-generation biosensor technologies, today announced that it has received its ISO 13485:2016 certificate from GMED, a notified body designated under the European Union Medical Device Regulation (MDR). The certificate covers the design, development and manufacture of the Lumee Oxygen tissue-integrated biosensors and associated readers (the Lumee Oxygen Platform) at the Company's Berkeley, California facility. Its issuance follows the positive certification decision Profusa announced on September 24, 2026.

ISO 13485 is the internationally recognized standard for medical device quality management systems. Certification demonstrates, through independent audit, that Profusa's quality management system conforms to the applicable requirements of ISO 13485:2016 within the scope of certification. ISO 13485:2016 certification is a significant step supporting the Company's ongoing MDR conformity assessment activities for the Lumee Oxygen Platform. ISO 13485 certification is also commonly expected of medical device suppliers during European hospital procurement and distributor qualification processes. CE marking would indicate conformity with applicable EU MDR requirements and permits the Company to pursue commercial distribution in the European Union, subject to satisfying applicable regulatory and operational requirements.

Europe: the foundation for MDR and order fulfillment. A certified quality management system, as demonstrated by Profusa's ISO 13485:2016 certification, is a core element of conformity assessment under the MDR. With the ISO certificate in hand, Profusa continues to work with GMED to complete the remaining MDR conformity assessment activities for the Lumee Oxygen Platform, which, if successfully completed, would support issuance of the MDR certificate and CE marking. Importantly, with the ISO certificate, Profusa can now begin manufacturing the Lumee Oxygen Sensor Platform.

United States: aligned with FDA's quality framework. FDA's Quality Management System Regulation (QMSR), effective February 2, 2026, incorporates ISO 13485:2016 by reference. While ISO 13485 certification does not constitute FDA clearance or approval, nor replace applicable FDA regulatory requirements, it demonstrates conformity with an internationally recognized quality management system standard incorporated into FDA's updated regulatory framework.

"Obtaining ISO 13485 certification provides potential customers, partners, and interested physicians with independent confirmation that Profusa's quality management system conforms to an internationally recognized medical device standard. This certification provides an important foundation as we continue working toward completion of our remaining MDR conformity assessment activities, obtaining MDR certification and CE marking, and preparing for future commercialization in Europe," said Ben Hwang, Ph.D., President of Profusa.

There can be no assurance regarding the timing or outcome of GMED's remaining MDR conformity assessment activities, MDR certification, the timing of CE marking, or the timing of any market entry.
