Abstract:
1. An apparatus for introducing at least one 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 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 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 at least one agent to the pressure and volumetrically controlled gas only while it is flowing through the second flow path.
