Patent ID: 8469289

Claim:
A tissue sealant applicator system comprising: a tissue sealant applicator including an elongate body forming a bore containing a tissue sealant component, a piston to eject the tissue sealant component from the bore, and a spray adaptor in fluid communication with the bore and forming a gas flow path; a control unit adapted to be connected to a gas source and disposed in a housing separate from the tissue sealant applicator; and a first gas passageway connecting the gas flow path and the control unit; the tissue sealant applicator further including an actuating member cooperatively associated with the piston to eject the tissue sealant from the bore upon actuation by a user, and the control unit 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.
