Elana bv develops and manufactures medical devices for bypass surgery. The Elana procedure is designed to make traditional bypass procedures safer and easier. The medical devices are marketed by our company and are available in the Elana Surgical Kit. This ELANA (Excimer Laser Assisted Non Occlusive Anastomosis) Surgical Kit is based on the invention of Prof. C. Tulleken and his research team of the department of neurosurgery in UMC Utrecht and was the result of their desire to help these patients who could previously not be treated. The past years over 450 lives have been saved with this Elana technique in Europe, the US and Canada and over 100 neurosurgeons have been trained to use this technique. The Elana Surgical Kit is the only technique available to make a bypass in the brain without temporary occlusion of the blood-flow. This can significantly diminish the risk of stroke.
