Abstract

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.

Claims6

Dependent claims

A method for dispensing a first component of an adhesive tissue sealant stored in the dispenser as dry powder that is dissolved prior to use by introduction of a solvent, the method comprising:

(a) providing a first carpule comprising a first septum at one end, an open end opposite the first septum, and a first movable plug disposed therein, the first carpule containing the dry powder stored between the first septum and the first movable plug;
(b) introducing the solvent into the first carpule to dissolve the dry powder to form a solution of the first component by piercing the first septum with a syringe and injecting the solvent into the first carpule;
(c) installing the first carpule in a housing having a piercer;
(d) placing a piston within the open end of the carpule to contact and advance the first movable plug;
and
(e) piercing the first septum with the piercer of the housing to afford passage of the solution of the first component via a flow path to a nozzle from which the first component is dispensed.
