External mixer assembly
First Claim
1. A fluid delivery system for dispensing a multicomponent biological adhesive having at least a first component and a second component, the system comprising:
- a housing configured to receive a plurality of reservoirs;
a discharge nozzle housing a conduit assembly having a plurality of conduits with a proximal end thereof in respective fluid communication with separate of said reservoirs, a distal end of said conduits defining at least two exit openings, wherein each of said plurality of reservoirs includes a sealable opening configured for being penetrated by a proximal end of a respective one of said plurality of conduits; and
a deflector assembly provided on said housing, said deflector assembly having a deflector plate substantially parallel with said at least two exit openings, said deflector plate displaced at a distance from a distal-most end of said housing and oriented to deflect said first and second components after exiting from said at least two exit openings.

Abstract
An external mixer assembly is provided which externally mixes and delivers a first and a 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 reservoir containing the second component. The housing further includes a discharge nozzle defining a longitudinal axis for enclosing therein a conduit assembly having a first and a second conduit in communication with the first and second reservoir, respectively. A deflector assembly is connected to the discharge nozzle. The deflector assembly includes a deflector plate to provide a space for initial mixing of the first and second components. The deflector plate 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.

15. A fluid delivery system for dispensing a multicomponent biological adhesive, the system comprising:
-
a conduit assembly housed within a housing, said conduit assembly having two conduits each having an exit opening; a reservoir assembly having a first reservoir containing the first adhesive component and a second reservoir containing the second adhesive component, the first and second reservoirs being in fluid communication with a respective one of the two conduits, wherein the first and second reservoirs each include a sealable opening configured for being penetrated by a proximal end of the two conduits; and a deflector assembly having a deflector plate displaced at a distance from a distal end of said housing for receiving the first and the second adhesive components from the two conduits and deflecting the first and second adhesive components prior to dispensing to an application site, wherein said deflector plate is substantially parallel to each of said exit openings. - View Dependent Claims (16, 17)
