Abstract
A needle is proposed including a cannula or hollow shaft with a multilumen insert inside. The insert comprises at least two lumen. Both the insert as well as the cannula have bevelled ends. In the insert substantially straight cleaved fibers are present that may be connected at the proximal end to a console. At least one of the distal fiber ends in the insert may protrude more than half the fiber diameter out of the insert. Furthermore, the bevel angle of the insert is different from the bevel angle of the cannula such that combination cannula and insert is such that the fiber ends do not protrude the bevel surface of the cannula.
