A laparoscopic tissue sealant spray apparatus and system having a laparoscopic tissue sealant spray assembly combined with a trocar assembly, the tissue sealant spray assembly having an elongate delivery tube. A spray outlet at a distal end of the elongate delivery tube may be rounded or angled. A ring member provided at the distal end of the elongate delivery tube directs a spray cone toward a portion of a target tissue site, and the spray cone may be repositioned to a different portion of the target tissue site by rotation of the elongate delivery tube. The trocar assembly includes a vent opening that connects to a venting valve member that provides a vent path which passively opens upon operation of the tissue sealant spray assembly, avoiding excessive pressure build-up within a body cavity.
