A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal. Also shown, for use with, or without, the chamber, is an agent chamber adapted to be coupled to at least one structure defining at least one fluid flow path extending at least a portion of the distance between an insufflation device and the body cavity, body space or body surface.

The invention claimed is: 1. An apparatus for introducing anesthetic agent into the abdomen of a patient comprising: a) an insufflation device to provide pressure and volumetrically controlled gas in a manner suitable for laparoscopic surgery, in a volume to provide full insufflation of the abdomen

The invention claimed is: 1. An apparatus for introducing anesthetic agent into the abdomen of a patient comprising: a) an insufflation device to provide pressure and volumetrically controlled gas in a manner suitable for laparoscopic surgery, in a volume to provide full insufflation of the abdomen; b) a heater/hydrator connected to the insufflation device downstream thereof, the heater/hydrator having a heater and an absorbent material contained therein; c) at least a first structure comprising at least a first fluid flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the insufflation device and the heater/hydrator; d) at least a second structure comprising at least a second flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the heater/hydrator and the abdomen; and e) an agent chamber or a modified agent chamber isolated and external from the heater/hydrator connectable to either the first structure, or the second structure, or both, to supply the anesthetic agent to the pressure and volumetrically controlled gas flowing through either the first flow path, or the second flow path, or both, while it is flowing in the first structure, or the second structure, or both, thereby supplying the anesthetic agent containing gas stream to the interior of the abdomen through either the first flow path, or the second flow path, or both. 2. The apparatus of claim 1, further comprising a dispersion device external and separate of the heater/hydrator configured to cause dispersion of the at least one antibiotic agent. 3. The apparatus of claim 1, wherein the agent chamber or modified agent chamber is pre-charged. 4. The apparatus of claim 1, wherein the agent chamber or modified agent chamber has an external port to accept a charging device. 5. The apparatus of claim 4, wherein the charging device is a syringe. 6. The apparatus of claim 1, wherein the agent chamber or modified agent chamber is a syringe. 7. The apparatus of claim 1, wherein the agent chamber or modified agent chamber is a bag. 8. The apparatus of claim 1, wherein the agent chamber or modified agent chamber is a pump. 9. The apparatus of claim 2, wherein said dispersion device produces an aerosol. 10. The apparatus of claim 2, wherein said dispersion device produces a spray. 11. The apparatus of claim 2, wherein said dispersion device produces a mist. 12. The apparatus of claim 2, wherein said dispersion device produces a fog. 13. The apparatus of claim 2, wherein said dispersion device produces a vapor. 14. An anesthetic agent delivery system for use with an insufflation device capable of providing pressure and volumetrically controlled gas in a manner suitable for laparoscopic surgery to the abdomen of a patient comprising: a) a first structure upstream of a heater/hydrator comprising a single and direct fluid flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the insufflation device and the heater/hydrator; and b) an agent chamber or a modified agent chamber separate and distinct from the heater/hydrator connected to the a first structure and adapted to supply the at least one anesthetic agent to the pressure and volumetrically controlled gas flowing through the single and direct fluid flow path while the pressure and volumetrically controlled gas is in the first structure, thereby delivering an anesthetic agent containing gas stream to the interior of the abdomen through the single and direct flow path. 15. The apparatus of claim 14, comprising a dispersion device in fluid communication with the agent chamber or a modified agent chamber and downstream thereof. 16. The apparatus of claim 14, comprising a dispersion device interposed between the agent chamber or a modified agent chamber and a trocar. 17. The apparatus of claim 14, wherein the agent chamber or modified agent chamber is pre-charged. 18. The apparatus of claim 14, wherein the agent chamber- or modified agent chamber has an external port to accept a charging device. 19. The apparatus of claim 1, wherein the agent chamber or modified agent chamber is a piezoelectric chamber. 20. The apparatus of claim 4 further including: a) at least a third structure comprising at least a third flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the abdomen and an agent chamber; and b) the agent chamber separate and external from the heater/hydrator connected to the third structure instead of either the first structure or the second structure and adapted to supply the at least one anesthetic agent to the pressure and volumetrically controlled gas flowing through the at least a third structure, thereby delivering the anesthetic agent to the interior of the abdomen through the third flow path. 21. An apparatus for introducing an anesthetic agent into the abdomen of a patient comprising: a) a source of insufflation gas to provide pressure and volumetrically controlled gas in a manner suitable for laparoscopic surgery, in a volume to provide full insufflation of the abdominal cavity: b) a heater/hydrator connected to the insufflation device downstream thereof, the heater/hydrator having a heater and an absorbent material contained therein; c) at least a first structure comprising at least a first fluid flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the insufflation device and the heater/hydrator; d) at least a second structure comprising at least a second flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the heater/hydrator and the abdomen; and e) an agent chamber or a modified agent chamber separate and external from the heater/hydrator connected to both the first structure and the second structure to supply the antibiotic agent to the pressure and volumetrically controlled gas flowing through the first structure and the second structure thereby delivering an anesthetic agent containing gas stream to the interior of the abdomen of a patient. 22. An anesthetic agent delivery system for use with a source of insufflation gas capable of providing pressure and volumetrically controlled gas in a manner suitable for laparoscopic surgery to the abdomen of a patient comprising: a) at least a first structure comprising a single and direct fluid flow path for the pressure and volumetrically controlled gas extending at least a portion of the distance between the source of insufflation gas and the heater/hydrator, and being up-stream of the heater/hydrator; b) an agent chamber or a modified agent chamber separate and distinct from the heater/hydrator connected to the at least a first structure and adapted to supply the at least one anesthetic agent to the pressure and volumetrically controlled gas flowing through the first structure, thereby delivering an anesthetic agent containing gas stream to the interior of the abdomen of a patient.
