A legend 26 years in the making...


Onesys Oy or Onesys Medical is a privately owned shareholder company established in 1991 in Oulu, Finland. Our vision led to the creation of tools for minimally invasive surgery and methods to handle the massive needs already apparent when industrial scale digital health care information systems (EMR, PACS) were being setup for the first time in history.

John (Ph.D, Professor of Neurosurgery) and Pirjo (Ph.D, Docent of Health Economics) Koivukangas identified the demand for better integration of pertinent information, not only among databases and device platforms but also the various sectors of the economy.  The unique perspective toward developing new solutions at Onesys can be called "Cluster-derived" as the company has harnessed the potential found in industry, health care and academia.

Onesys solutions are currently in use in every major hospital in the world.
