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.

Multi-pressure biocompatible agent delivery device and method

A modular system is described for construction of fluid applicators for open or endoscopic surgery from modular components. Lengths of tubing of various lengths, and devices to be carried by said tubing, are pre-fitted with standard adapters to mate with each other, thereby forming cannula sections and applicator sections. Interconnectors may also be provided, particularly for provision of articulation. The tubing is preferably rigid, but may also be either flexible or permanently bendable. A device can then be constructed by selection of a suitable set of tubing lengths, adapters and applicators. Devices customizable for particular uses can be created with minimal expense. The system is especially suitable for delivery of fluids to tissue in endoscopic or other minimally invasive surgical procedures. Delivery of fluids forming structure at a tissue site, especially as a hydrogel, is a preferred use of the devices.
