Patent ID: 7217254

Claim:
A device constructed and arranged for application of a biocompatible agent to a surface, comprising a regulation system switchable between a first position arranged to direct delivery of a biocompatible agent to the surface via a medical gas at a first medical gas pressure, and a second position arranged to direct delivery of the biocompatible agent to the surface via a medical gas at a second medical gas pressure; further comprising a first biocompatible agent conduit connectable to a source of a first biocompatible agent, the conduit including a first biocompatible agent outlet adapted to emit the first biocompatible agent for delivery to the surface, and a gas conduit connectable to a source of a pressurized medical gas and having an outlet adapted to emit pressurized medical gas in an orientation carrying the first biocompatible agent from the first biocompatible agent outlet to the surface; further comprising a second biocompatible agent conduit connectable to a surface of a second biocompatible agent, the second conduit including a second biocompatible agent outlet adapted to emit the second biocompatible agent; wherein the second biocompatible agent outlet is positioned to emit the second biocompatible agent in relation to a pressurized medical gas outlet in an orientation carrying the second biocompatible agent from the second biocompatible agent outlet to the surface; further comprising a regulation system having a first preset treatment position arranged to direct delivery of the first biocompatible agent to the surface via a medical gas at a first medical gas pressure, and a second preset treatment position arranged to direct delivery of the medical gas to the surface in the absence of any biocompatible agent; the regulation system further including a third preset treatment position arranged to direct delivery of the second biocompatible agent to the surface via a medical gas at the first medical gas pressure; the regulation system further including a fourth preset treatment position arranged to deliver the second biocompatible material to the surface via a medical gas at a second medical gas pressure which is lower than the first pressure; the regulation system further including a default position arranged to expel medical gas in the vicinity of the first and second biocompatible agent outlets in the absence of delivery of any biocompatible agent; and wherein the regulation system includes at least one switch, operable by a user of the device, each switch biased such that in the absence of its activation by a user of the device the regulation system is set at the default position.
