US 6,783,514 B2 · Fibrin sealant applicator

Abstract

An applicator is provided for dispensing a first and a second component of a biological adhesive. The applicator 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 an elongated body portion 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. An activator assembly is provided which includes an activator and a rachet mechanism for compressing the reservoirs within the housing for dispensing the biological components into the conduits. An applicator tip having two separate channels in communication with the conduits may be provided on a distal end of the elongated body portion for dispensing the components on the application site. The first and second components are preferably fibrinogen and thrombin which intermix to form a fibrin sealant.

Dependent claims

An applicator for dispensing a multicomponent biological adhesive, the applicator comprising:

a housing configured for operatively enclosing at least two self-contained collapsible reservoirs each having a sealable opening therein and storing at least one component of a multicomponent biological adhesive;
a conduit assembly extending from said housing and having a pair of conduits in fluid communication with said housing;
and
an activator assembly provided on said housing having an activator moveable from a first position to a second position within the housing to decrease the volumetric capacity of said housing and substantially and simultaneously compress the at least two self-contained collapsible reservoirs at a proximal end and a distal end to dispense at least one component through at least one of said pair of conduits to a distal end thereof, wherein the activator moves along a direction substantially perpendicular to a direction of fluid flow of the at least one component within a major portion of at least one of said pair of conduits.

An applicator for dispensing a first and a second component of a biological adhesive, the applicator comprising:

a housing having at least one compartment configured for operatively receiving therein a first self-contained collapsible reservoir and a second self-contained collapsible reservoir;
a first dispensing conduit in fluid communication with an interior chamber of said first self-contained collapsible reservoir when said first self-contained collapsible reservoir is operatively received by said housing for dispensing a first component provided within said interior chamber of said firs self-contained collapsible reservoir from a distal end of said first dispensing conduit;
a second dispensing conduit in fluid communication with an interior chamber of said second self-contained collapsible reservoir when said second self-contained collapsible reservoir is operatively received by said housing for dispensing a second component provided within said interior chamber of said second self-contained collapsible reservoir from a distal end of said second dispensing conduit;
and
an activator assembly for exerting pressure on the first and second reservoirs as said activator assembly moves from a first position to a second position within the housing to decrease the volumetric capacity of said housing and to substantially and simultaneously compress the reservoirs at a proximal end and a distal end for dispensing the components provided within said interior chambers thereof to the dispensing conduits, wherein the activator assembly move along a direction substantially perpendicular to a direction of fluid flow of the first component within a major portion of the first dispensing conduit.
