An external mixer assembly (109) is provided which externally mixes and delivers a first and second component of a biological adhesive to tissues or organs for sealing wounds, stopping bleeding and the like. The first and second components are mixed immediately after exiting from separate outlet ports disposed in fluid communication with component reservoirs. In on embodiment, the external mixer assembly includes a housing having a housing head for enclosing therein a first reservoir containing the first component, and a second component. The housing further includes a discharge nozzle (120) defining a longitudinal axis for enclosing therein a conduit assembly having a first (120) and a second conduit (24, 26) in communication with the first and second reservoir, respectively. A deflector assembly (140) is connected to the discharge nozzle. The deflector assembly includes a deflector plate (144) to provide a space for initial mixing of the first and second components. The deflector plate (144) is oriented in generally parallel juxtaposed relation distal to the distal face of the discharge nozzle. The first and second components are preferably fibrinogen and thrombin which intermix to form a fibrin sealant. |
