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.

1. A method for introducing at least one agent into the abdomen of a patient consisting of: a) providing 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 abdominal cavity;b) prov
1. A method for introducing at least one agent into the abdomen of a patient consisting of: a) providing 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 abdominal cavity;b) providing a single and direct flow path between the insufflation device and the abdomen of a patient,c) operating the insufflation device to provide a flow of the pressure and volumetrically controlled gas in the single and direct flow path, andd) introducing an agent into the pressure and volumetrically controlled gas stream while the gas stream is in the single and direct flow path thereby providing an agent containing gas stream to the patient's abdomen. 2. A method for introducing at least one agent into the abdomen of a patient consisting of: a) providing a single 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 abdominal cavity;b) providing a heater/hydrator connected to the single insufflation device downstream thereof, the heater/hydrator having a heater and an absorbent material contained therein, and heating and hydrating the gas passing there through;c) providing at least a first structure comprising at least a first 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) providing 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;e) providing an agent chamber or a modified agent chamber separate and external from the heater/hydrator connected to either the first structure or the second structure, or both, to supply the at least one agent to the pressure and volumetrically controlled gas while it is flowing through either the first flow path, or the second flow path, or both;f) operating the single insufflation device to provide a flow of pressure and volumetrically controlled gas through the first structure, the heater/hydrator and the second structure, thereby causing a flow of pressure and volumetrically controlled gas between the insufflation device and the patients abdomen, andg) supplying the at least one agent from the agent chamber to the pressure and volumetrically controlled gas, thereby causing an agent containing gas stream to be delivered to the patient's abdomen. 3. A method for introducing at least one agent into the abdomen of a patient comprising: a) providing 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 abdominal cavity;b) providing a heater/hydrator directly connected to the insufflation device downstream thereof, the heater/hydrator having a heater and an absorbent material contained therein and heating and hydrating the gas passing through the heater/hydrator;c) providing a first structure comprising a first fluid path for the pressure and volumetrically controlled gas extending between the insufflation device and the heater/hydrator;d) providing a second structure comprising a second flow path for the pressure and volumetrically controlled gas extending between the heater/hydrator and the abdomen;e) providing an agent containing chamber or a modified agent containing chamber separate and external from the heater/hydrator connected to either the first structure or the second structure to supply the agent to the interior of the abdomen through the pressure and volumetrically controlled gas by adding the agent to the pressure and volumetrically controlled gas while it is flowing through either the first flow path, or the second flow path, or both, andf) flowing the pressure and volumetrically controlled gas from the insufflation device through the first structure, the heater/hydrator and the second structure; andg) supplying the agent from agent containing chamber or the modified agent containing chamber to the pressure and volumetrically controlled gas while it is in the first structure or the second structure, thereby supplying an agent containing gas stream to the abdomen of a patient. 4. The method defined in any one of claims 1, 2, and 3, wherein the agent is a chemotherapy agent. 5. The method defined in any one of claims 1, 2, and 3, wherein the agent is an antibiotic agent. 6. The method defined in any one of claims 1, 2, and 3, wherein the agent is an anesthetic agent. 7. The method defined in any one of claims 1, 2, and 3, wherein the agent is an anti-adhesion agent. 8. The method defined in any one of claims 1, 2, and 3, wherein the agent is a combination of one or more of an antibiotic agent, an anesthetic agent, a chemotherapy agent, or an anti-adhesion agent.
