ABSTRACT:
An applicator for dispensing a first and second component of a biological adhesive, such as fibrin glue. At least one of said components may contain a suspension of fibrin microbeads (FMB) or a suspension of cells. The present invention uses a single supply of pressurized gas to force the components from the applicator using positive fluid pressure and to atomize them into a convergent spray. Another embodiment of the present invention also provides for the endoscopic application of the biological adhesive directly to tissue defects. The application of positive pressure allows precise metering of the components and application of the adhesive, prevents internal coagulation of the fibrin or clogging by suspended particles and reduces waste and contamination of the components.
