The ELANA Technique is invented by professor Tulleken from the University Medical Center (UMC) in Utrecht, The Netherlands. In contrast to the conventional technique, the ELANA Technique facilitates the construction of a bypass without the need to temporarily close the recipient brain artery.

The ELANA Technique is only concerned with how the bypass is connected to the artery in your brain. This is a relatively short step in the entire operation. It generally takes less than one hour. It can take two or more hours in exceptionally difficult situations. The ELANA Technique involves the use of the Elana Arteriotomy System, which contains the products that are neccessary to create the bypass non-occlusive.

The Elana Arteriotomy System has been approved in Europe, Canada and the USA.
