A medical apparatus for dispensing a biologically active compound. The medical apparatus includes a sleeve, wherein (1) the sleeve has a working channel defined therein through which medical instruments may be advanced, (2) the sleeve includes a fluid delivery channel which is distinct from the working channel, (3) the fluid delivery channel has an exit, and (4) the sleeve includes a housing having an interior cavity defined therein. The medical apparatus also includes an insufflation valve in fluid communication with the working channel. The insufflation valve is positionable between an open position and a closed position such that (i) when the insufflation valve is located in the open position an insufflation gas can be advanced into the working channel and (ii) when the insufflation valve is located in the closed position the insufflation gas is prevented from being advanced into the working channel. The medical apparatus further includes a chemical container having an interior void defined therein for receiving the biologically active compound, wherein the interior void is in fluid communication with the exit through the fluid delivery channel when the chemical container is positioned within the interior cavity of the housing such that the biologically active compound may be delivered through the fluid delivery channel to an outer surface of the sleeve. |
