In " arteriotomy ", an artery was punctured, although generally only in the temples.

In conventional techniques, the recipient artery is temporarily interrupted ( occluded with clips ) and opened using microscissors or scalpel, while in the ELANA technique blood flow is not interrupted and the opening ( arteriotomy ) is created with radiation from a 308 nm excimer laser delivered through a catheter inserted in the vessel that will become the bypass while blood continues to flow through the artery that receives the bypass.
