Patent ID: 6860870

Claim:
A device for applying a biocompatible agent to a tissue surface, comprising: a housing having a biocompatible agent conduit connectable to a source of a biocompatible agent, the conduit including a biocompatible agent outlet adapted to emit a biocompatible agent; a gas conduit associated with the housing, connectable to a source of a pressurized medical gas and having an outlet adapted to emit pressurized medical gas in an orientation carrying biocompatible agent from the biocompatible agent outlet to a tissue surface; and a gas regulator adapted to provide medical gas to the outlet of the gas conduit at at least two predetermined positive gas pressures, wherein the at least two predetermined gas pressures include a first predetermined gas pressure sufficient to carry a biocompatible agent from the biocompatible agent outlet to the tissue surface, and a second predetermined gas pressure less than the first pressure, sufficient to clear residual biocompatible agent from the biocompatible agent outlet.
