A disposable cartridge for holding compressed medical gas includes a substantially cylindrical canister. The canister is delivered by an elongate cylindrical body that is tapered to a reduced diameter end portion having a discharge port or opening formed therein. The discharge port is covered by a pierceable tip that seals the canister to hold compressed medical gas with an interior chamber of the canister. The tip is selectively punctured to discharge the medical gas through the opening for use in a medical procedure.
