ABSTRACT:
A sealant applicator suitable for dispensing a coagulable sealant, for example a two-component fibrin sealant mixed in the applicator, employs impulse clearing to remove residual coagulated or coagulating material from the dispensing pathway and mixing chamber, if present. Impulses may be generated by manual application of a clearing member such as a plunger which can enter into the dispensing pathway to engage, dislodge and discharge residuals or can generate a gas impulse to impact the residuals to similar effect. A clearing valve having a clearing port can be operated by movement of the clearing member to provide access to the dispensing pathway.
