Disclosed is a dispenser for separately dispensing each of two biological fluids contained therein for intermixing at a site outside of the dispenser to produce hemostasis or a tissue adhesive. 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.

A dispenser for separately dispensing each of two biological fluids contained therein for intermixing at a remote site to produce hemostasis or a tissue adhesive, comprising: a housing having a dispenser head thereon for separately dispensing each of two fluids; a first and second pump in the housing; a first hollow aspirating needle in the housing, in fluid communication with the first pump; a second hollow aspirating needle in the housing, in fluid communication with the second pump; and a chamber in the housing for removably receiving a first and a second reservoir of biological fluids to be dispensed, wherein each of the first and second aspirating needles extends into the chamber for providing fluid communication with each of the first and second reservoirs of biological fluid, respectively, so that activation of the first and second pump produces a flow of biological fluid from the first and second reservoirs through the first and second aspirating needles and out of the dispenser head for intermixing at a remote site outside of the dispenser.
