Unified punch inflation and sealing tool

A tool for introducing fluid into a sealed volume comprising:

• an electrode having an outer circumference and an inner circumference, the inner circumference defining a volume within the electrode, the electrode being mechanically coupled to a base at a first end of the electrode, the electrode being open at a second end;
• an actuator mechanically coupled to the base;
• a punch having a punch head, the punch being coupled to the actuator, the punch head residing within the volume in the electrode in a first punch position and being outside of the volume of the electrode in a second punch position, the punch head comprising a punch edge defining a perimeter, a surface of the punch within the perimeter of the punch edge being concave and defining a punch volume, an average depth of the punch volume being less than an average diameter of the punch edge;
• and
• a first fluid delivery conduit, the first fluid delivery conduit being in fluid communication with the volume in the electrode and in fluid communication with the opening at the second end of the electrode.
