Abstract
A device for application of material to a surface, for example, biocompatible material to a tissue surface in a medical or clinical setting, is adapted to receive one or more biocompatible materials and one or more sources of pressurized medical gas, and to deliver these biocompatible materials via the medical gas(es) to a tissue surface or other surface. A regulation system controls flow of medical gas at a variety of pressures, and flow of biocompatible agent or agents, allowing agents to be sprayed or otherwise deployed onto a tissue surface. Switching apparatus operably connected to the regulation system directs a set of preset treatment positions allowing sequential application of biocompatible materials under various conditions in conjunction with an overall treatment protocol. The device can be used to apply a photoinitiating primer and polymeric sealant to a tissue surface, followed by light activation to form a polymer coating on the surface. The device can easily be operated in a variety of orientations by a user, with switching apparatus arranged for logical, stepwise progression through the protocol in any orientation.
