Patent ID: 7744557

Claim:
An apparatus for introducing antibiotic 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 upstream of the heater/hydrator to supply the antibiotic agent to the pressure and volumetrically controlled gas while it is flowing through the first flow path thereby delivering an agent containing gas stream to the interior of the abdomen through the first flow path.
