Abstract
The present inventions are directed to spray tips for multidirectional or three-dimensional spraying of an unmixed two-part sealant and/or hemostat comprising a first biocompatible component and a biocompatible second component onto a tissue or wound comprising: a hollow body having inside a first component distribution compartment and a second component distribution compartment, said compartments not in fluid communication with each other. The first component can contain one or more biologic components, preferably fibrinogen and the second component can contain one or more biologic component different from the first biologic component, preferably thrombin and/or thrombin precursors. The present inventions are also directed to methods of spraying the unmixed two-part sealant or hemostat using the spray tip and associated components described above by simultaneously expressing the first component and the second component from the syringes.
