Abstract

A sealant delivery device includes a delivery tube, a bioadhesive container, and an adapter. The delivery tube includes proximal and distal ends. The bioadhesive container holds a sealant activator and a sealant precursor separated from each other. The adapter is interposed between the delivery tube and the bioadhesive container. The adapter includes a first channel member that couples a first lumen of the delivery tube to the sealant activator, and a second channel member that couples the first lumen to the sealant precursor. The adapter provides separation of the sealant activator and the sealant precursor until a position distal of the bioadhesive container.
