A novel device and method for the application of two or more components of a fibrin sealant using a gas is disclosed. The novel device and method involve the concentric arrangement of annular apertures for each of the components concentric with and radially outward of a center gas discharge aperture in the exit end of a spray head. Reservoirs for each component, for example syringe cartridges or cylinders, are in dextrete fluid communication with the spray head and preferably can be activated by a common means.

A device for applying a fibrin sealant comprising two components which will form said sealant when combined, which device comprises commonly actuable reservoirs for each of said components and a source of gas, wherein each of said reservoirs and said gas in separate fluid communication via a discret

A device for applying a fibrin sealant comprising two components which will form said sealant when combined, which device comprises commonly actuable reservoirs for each of said components and a source of gas, wherein each of said reservoirs and said gas in separate fluid communication via a discrete channel to a spray head, said spray head having a first aperture located centrally in an exit end of said spray head through which said gas is discharged, said spray head having a first annular aperture in the exit end of said spray head within first annular aperture is concentric with said first aperture and through which one of said fibrin-sealant-forming components is discharged, and a second annular aperture in the exit end of said spray head being concentric with said first aperture and concentric with, and having a radius larger than said first annular aperture through which the second of said fibrin-sealant-forming components is discharged wherein all of said apertures are in a common plane.
