Directional endoscopic delivery of material

Claim 1

A directional application device for insertion of a directional spray nozzle into an internal cavity of a human or animal and applying therethrough one or more components to a desired internal site of a human or animal within a desired range of angular directions, the system comprising (a) a source of the components; (b) means for fluid communication integral at a first means end with the source of one or more components and at a second means end with the directional nozzle; and (c) the directional spray nozzle comprising (i) an inner tube of resilient material, the inner tube integral at a first tube end with the second means end and having a nozzle member at a second tube end, the second end being bent to the maximum angle within the desired range of directions, the second end being adapted to avoid piercing tissue in the internal cavity, the inner tube slidably movable within an outer tube, and wherein the inner tube is a multilumen tubing with discrete lumen for two or more components; and (ii) the outer tube of a material more rigid than the inner tube and having an opening at one end to allow the inner tube to slidably project through the opening, whereby the amount of projection of the bent end of the inner tubing through the opening determines the angular direction of the spray nozzle; wherein the one or more components form a fibrin sealant.
