Born to make things better

About Sirius Medical

As a spin-off from the Netherlands Cancer Institute, Sirius Medical has its roots firmly embedded in the surgical clinic.

Developing technology by and for clinicians, we were born to make things better.

From this work resulted the first development and clinical demonstration of magnetic seed localization (MaMaLoc). The researchers recognized the need and opportunity to simplify and improve the localization technology for the surgical removal of breast cancers, ultimately resulting in the Sirius Pintuition technology.

We are proud of our partnerships with medical professionals; together we develop surgical solutions to better treat cancer.


We improve healthcare for cancer patients through our effective, affordable localization system, enabling the precise and efficient surgical removal of tumors

We strive to be a trusted partner in the clinic and for the surgical treatment of cancer patients:

  • Intuitive and accurate devices that enable surgeons to deliver optimal care
  • Compelling evidence on performance, outcomes, and health-economics
  • Affordable solutions that provide value across the patient care pathway
