Claim:
A device, comprising: an elongate cannula having a proximal portion adapted to be located outside a body during a surgical procedure, and a distal portion adapted to be located within the body during the surgical procedure and adjacent a surgical site to which a curable biocompatible material is to be delivered, the cannula comprising: an outer wall; a first interior lumen disposed between the proximal and distal portions through which the biocompatible material is delivered, a wall of the first lumen including a first wall portion capable of transmitting light therethrough; a second interior lumen disposed adjacent the first interior lumen and adapted to transmit light within the second lumen, a wall of the second lumen including a second wall portion capable of transmitting light therethrough, the first and second wall portions being generally aligned so that light from the second lumen may pass through the first and second wall portions to photo initiate cross-linking of the biocompatible material in the first lumen; a blocking element positioned in at least one of the first or second lumens and movable between a first position wherein light from the second lumen may pass through at least a part of the first and second wall portions to the first lumen, and a second position wherein less light may pass through at least one of the first and second wall portions than in the first position; and an end of the cannula to be located adjacent a surgical site.
