A laparoscopic applicator device (10) for the selective directional application of one or more liquids to a surgical site is disclosed. The device (10) comprises a handle (12) with liquid inlets (16, I8, 20) at one end, discrete channels within one or more tubes (21) connecting with said inlets (16, 18, 20) extending through said handle (12) to a nozzle (22), and a dual injection shaft (14) at the nozzle end for inserting the shaft (14) and nozzle (22) through a surgical trocar. The dual shaft (14) comprises a rigid portion immediately adjacent the handle (12) and a flexible portion near the nozzle tip. Means are provided preferably within the handle (12), for the controlled articulation of the flexible shaft (14)/nozzle (22) assembly, thereby providing applicati on of the liquids in a desired direction. The present invention is particularly useful in the application of surgical sealants, e.g., fibrin sealants. Methods of applying such components are also a part of the invention.
