Abstract

A bioadhesive mixing assembly includes first and second syringes and an adapter. The first syringe includes first and second chambers holding a first sealant component and an activator, respectively. The second syringe includes third and fourth chambers holding a second sealant component and one of an activator or a third sealant component, respectively. The adapter is mounted to the first syringe and includes first and second channels in flow communication with the first and second chambers, a first seal member providing sealed access to the first and second channels, first and second needles connected in flow communication with the third and fourth chambers, and a second seal member enclosing the first and second needles. Connecting the adapter to the second syringe punctures the first and second seal members with the first and second syringes to create flow communication between the first and third chambers and the second and fourth chambers.
