Brainlab is a privately held German medical technology company headquartered in Munich, Bavaria. Brainlab develops software and hardware for radiotherapy and radiosurgery, and the surgical fields of neurosurgery, ENT and craniomaxillofacial, spine surgery, and traumatic interventions. Their products focus on image-guided surgery and radiosurgery, digital operating room integration technologies, and cloud-based data sharing. Brainlab is featured in the German media on topics such as the digitalisation of healthcare data and artificial intelligence in healthcare.

History

Brainlab was founded in Munich in 1989, by CEO Stefan Vilsmeier. The first Brainlab product was a mouse-controlled, menu-driven surgical planning and navigation software, introduced in 1990 at the University of Vienna and exhibited at the Congress of Neurological Surgeons (CNS) Annual Scientific Meeting in Washington, D.C. in 1992.

In 1993, Brainlab developed a linear accelerator-based system for stereotactic radiosurgery using micromultileaf collimators. Three years later, Brainlab entered into a partnership with Varian, Inc., which resulted in a long-term collaboration in the field of radiosurgery.

Brainlab expanded into the field of image-guided surgery in 1997 and was the first to develop passive marker technology. In the same year, Brainlab introduced its first shaped-beam radiosurgery system, Novalis. Lance Armstrong, a professional cyclist and testicular cancer survivor, was the spokesperson for the Novalis brand during the early 2000s.

In 2007, the company released Novalis Tx Radiosurgery, a radiotherapy system jointly created by Brainlab and Varian Medical Systems, Inc. The same year, Brainlab collaborated with Siemens Medical Solutions to launch an intraoperative CT machine utilizing a rail-mounted scanner. In 2008, Digital Lightbox was brought to the market, allowing digital patient images to be viewed and adjusted in the operating room. Digital Lightbox was transformed into Buzz Digital O.R. in 2012.

In the following years, several Brainlab technologies and products received the Red Dot Design Award, including the Kick navigation system, the Curve technology and the Airo Mobile Intraoperative CT.

In March 2019, Smith & Nephew announced the acquisition of the orthopaedic joint reconstruction business unit from Brainlab to advance its efforts in robotic surgery. The same year, Brainlab recalled their spine and trauma 3D navigation software (version 1.0) because it could display inaccurate information during a procedure, which could prevent surgeons from accurately navigating surgical tools inside the patient.

On September 14, 2022, Stefan Vilsmeier, CEO and Claus Promberger, VP for R&D, from Brainlab, together with clinical partner Professor Cordula Petersen, MD from the UKE (Universitätsklinikum Hamburg-Eppendorf) in Hamburg, were nominated as one of the three finalists for the Federal President’s Award for Innovation and Technology (Deutscher Zukunftspreis) 2022 for the ExacTrac Dynamic technology, a highly precise radiation treatment for tumors in motion. The prize has been awarded annually by the German Federal President for over 25 years and honours outstanding technical, engineering, scientific as well as software and algorithm-based achievements within Germany.

In cooperation with the City of Munich, Brainlab financed the Munich-Riem memorial site, which commemorates the 1970 terrorist attack at the former Munich-Riem Airport. Reasons for the commitment included the local proximity of the former airport to the Brainlab company headquarters and the promotion of art in Munich. Brainlab commissioned the artist Alicja Kwade to design an eight-metre-high sculpture made of steel and bronze for the memorial site.

In May 2022, Brainlab acquired MedPhoton GmbH, a robotic imaging solutions developer and manufacturer based in Austria specialized for image guided radiation therapy and surgery.

In 2023, Brainlab ran a course in neurosurgery in Tanzania and donated a surgical navigation system to the Muhimbili Orthopaedic Institute. This engagement ist part of the Brainlab Social Program, a corporate social responsibility initiative by Brainlab.

Headquarters

Brainlab was founded in the parental home of CEO and founder, Stefan Vilsmeier, in 1989. By 1991, Brainlab had moved into its first official headquarters in the Munich suburb of Poing. After a wave of new hires in 1995, a larger space was needed and headquarters moved to the Bavarian town of Heimstetten, Germany. In 2006, Brainlab constructed and moved into its headquarters in Feldkirchen, Germany, just outside Munich. Edmund Stoiber, former minister-president of Bavaria, officially opened the new building in 2007. In December 2016, Brainlab moved into a newly constructed headquarters in the Munich suburb of Riem on the grounds of the former Munich-Riem Airport. The headquarters also have a restaurant and a fitness studio. Featured speakers at the official inauguration ceremony on July 11, 2017, were the Bavarian State Minister Ilse Aigner and German Chancellor, Angela Merkel.
