Systems and methods for a canister with pressure passages

A deployment unit for cooperating with a conducted electrical weapon to provide a stimulus signal through a human or animal target to impede locomotion of the target, the deployment unit comprising:

• one or more wire-tethered electrodes, the one or more electrodes positioned in the deployment unit prior to a launch of the one or more electrodes;
• a canister having a cavity therein and an opening, the opening in fluid communication with the cavity;
• a lid having a plurality of notches along a circumference thereof, the lid for sealing the opening to retain a pressurized gas in the cavity of the canister;
• wherein:
• after positioning the lid over the opening and placing the canister into an atmosphere of the pressurized gas:
• the pressurized gas from the atmosphere enters the cavity via the notches;
• the lid is welded to the canister to seal the lid and the notches thereby sealing the opening to retain the pressurized gas in the cavity;
• and
• after the canister is removed from the atmosphere of the pressurized gas and positioned in the deployment unit, the canister is pierced to release the pressurized gas to launch the one or more electrodes from the deployment unit toward the target to provide the stimulus signal through the target to impede locomotion of the target.

A method for launching one or more wire-tethered electrodes toward a human or animal target to provide a stimulus signal through the target to impede locomotion of the target, the method comprising:

• positioning a lid over an opening of a canister, the canister having the opening and a cavity therein, the opening in fluid communication with the cavity, the lid having a plurality of notches along a circumference thereof, the plurality of notches in fluid communication with the cavity;
• after positioning, placing the canister into an atmosphere of a pressurized gas, the pressurized gas from the atmosphere enters the cavity via the notches;
• while the canister is in the atmosphere of the pressurized gas, sealing the lid to the canister thereby sealing the opening to retain the pressurized gas in the cavity;
• after removing the canister from the atmosphere of the pressurized gas, piercing the canister to release the pressurized gas retained in the cavity to launch the electrodes toward the target;
• and
• after launching, providing the stimulus signal through the target via the electrodes to impede locomotion of the target.
