Abstract: A novel device and method for applying two or more liquid components, for example fibrin sealant-forming components, comprises sources of the components fliud communication with, but remote from, an applicator for delivering the components to a desired site. Preferably, the user of such a device and method can actuate the application of the components by providing a signal to a controller which dispenses components from their sources to, and out of, the applicator. Greater ease, accuracy and control are realized by the user since the sources of components and controller are remote from the applicator and therefore not manually held by the user.

Abstract: An applicator and an electro-mechanical applicator drive system for automatically emptying the liquid components from respective syringes in a controlled manner for co-applying fibrin sealant components with a gas to form a spray. The applicator drive system includes a piston elevator section which moves the syringe pistons of the respective syringes in unison. The applicator drive system further includes at least one syringe piston force sensor which senses a force required by the piston elevator section to move at least one of the syringe pistons forward and outputs a force sensor signal. A controller is provided which controls movement of a piston elevator of the piston elevator section based on the force sensor signal.
