20090152305 | HAND TRIGGERED TISSUE SEALANT SPRAY APPARATUS AND SYSTEM - An applicator includes a bore for containing a sealant component, a piston moveably positioned in the bore, a plunger member connected to the piston with a distal end disposed within the bore and a proximal end depending from the bore, a distal outlet communicating with the bore and connectable to a gas source, and an actuating member carried by the proximal end of the plunger member to move with the plunger member as the plunger member moves along the bore. The applicator may be used in a system with a gas source connected to the distal outlet, and a control unit connected to the actuating member and the gas source, the control unit adapted to supply gas to the distal outlet from the gas source essentially simultaneous with a force applied to the actuating member. | 06-18-2009 |
20100168779 | TISSUE SEALING SYSTEM AND APPARATUS - 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. | 07-01-2010 |
20110172703 | TISSUE SEALANT APPLICATOR SYSTEM - A tissue sealant applicator system includes a tissue sealant applicator having an elongate body forming a bore containing a tissue sealant component, a piston, and a spray adaptor in fluid communication with the bore and forming a gas flow path. The system also includes a control unit adapted to be connected to a gas source, and a first gas passageway connecting the gas flow path and the control unit. The applicator includes an actuating member cooperatively associated with the piston to eject the tissue sealant from the bore upon user actuation. The control unit is adapted to supply gas from the gas source to the first gas passageway essentially simultaneously with user actuation of the actuating member, and to permit the supply of gas to the spray adaptor from the gas source to continue to flow for a predetermined time delay after the user stops actuating the actuating member. | 07-14-2011 |
