A dispenser in which a dry powder (one component of a two-part adhesive tissue sealant and/or adhesive) is stored in a container (e.g., a carpule) having a septum at one end, an open end opposite the septum, and a movable plug. The powder is retained at the septum end of the container by the movable plug, which is displaced and pushed back as the solvent used for reconstituting the powder is introduced (e.g., through the septum). The second part of the tissue sealant is contained within a second container, also with a movable plug. After the first part is reconstituted, a manifold is fitted which pierces both septums and allows the contents to be dispensed. A dual syringe body supports the containers, and has pistons that enter the open ends to advance the movable plugs. Other embodiments of tissue adhesive and/or sealant dispensers and kits as well as methods of preparing tissue sealants are also described.

1. A dispenser for simultaneously dispensing first and second components of an adhesive tissue sealant, wherein at least the first component is stored in the dispenser as dry powder that is dissolved prior to use by introduction of a solvent, the dispenser comprising the combination of:(a) a first container comprising a first septum at one end, an open end opposite the first septum, and a first movable plug disposed therein, the first container containing a quantity of the first component in the form of a dry powder stored between the first septum and the first movable plug; (b) a second container comprising a second septum at one end, an open end opposite the second septum, and a second movable plug disposed therein, the second container containing a quantity of the second component; (c) a housing having a pair of cavities sized and configured to receive and support the first and second containers, each cavity having a base, (d) pistons sized and configured to be received in the open ends of the first and second containers to advance the first and second movable plugs; and the housing including a manifold sized and configured to fit over and pierce the first and second septums and to afford passage of the first and second components via first and second flow paths to a nozzle from which the first and second components are dispensed to combine to form the adhesive tissue sealant, first and second piercers mounted in the manifold for piercing the first and second septums, each piercer extending through and being supported by a disk that is supported adjacent the base of said each cavity, each disk being supported a distance spaced from the base of the first and second cavities to form first and second plenums, each plenum defined by said each disk and adjacent walls of said each cavity, the first and second piercers affording passage of the first and second components to the first and second plenums.
