The dispenser is compact, contains internal reservoirs of the two bioloical fluids, and is designed for efficient reloading with filled nonsterile containers without compromising the integrity of the sterile field. The dispenser is capable of dispensing the biological fluids, such as fibrinogen and thrombin, at either a focused point of in an aerosol mist. In addition, spray elements are disclosed for uniformly distributing the two biological fluids along either the interior surface or the exterior surface of an implantable vascular graft.
