Hydrogen production system

A medical sealant applicator device for delivery of a multi-component sealant, comprising:

• a first body having a base, a first syringe plunger, a second syringe plunger, and a longitudinal channel laterally interposed between the first syringe plunger and the second syringe plunger, wherein each of the first syringe plunger and the second syringe plunger is oriented to extend in a first direction from the base, the first syringe plunger having a first free end having a first proximal plunger piston, the second syringe plunger having a second free end having a second proximal plunger piston;
• a second body having a first syringe chamber, a second syringe chamber, and a longitudinal fluid chamber laterally interposed between the first syringe chamber and the second syringe chamber, the longitudinal fluid chamber having a proximal end and a distal end, the proximal end of the longitudinal fluid chamber being connected in fluid communication with each of the first syringe chamber and the second syringe chamber, the distal end of the longitudinal fluid chamber having a distal needle connector port, wherein:
• the first syringe chamber of the second body has a first distal opening to slidably receive the first proximal plunger piston of the first syringe plunger of the first body,
• the second syringe chamber of the second body has a second distal opening to slidably receive the second proximal plunger piston of the second syringe plunger of the first body, and
• the distal needle connector port of the longitudinal fluid chamber of the second body is able to translate in the longitudinal channel of the first body in response to the second body longitudinally translating relative to the first body;
• and wherein the medical sealant applicator device further comprises:
• a guide assembly to set a trajectory towards a targeted location and maintains the trajectory while advancing the needle assembly and injecting a component.

A method comprising:

• setting a trajectory for a needle assembly through a pleural space towards a target at a known distance and maintaining the trajectory while advancing the needle assembly;
• advancing the needle assembly at a first rate through the pleural space to the known distance;
• and
• applying a force to a proximal end of the needle assembly in a distal direction, wherein the force simultaneously injects a substance at a second rate.

A component delivery system, comprising:

• a needle assembly having an elongate needle comprising a proximal end and a distal end spaced a distance apart from one another and defining at least one fluid path therebetween, the distal end comprising one or more fluid outlets coupled to the at least one fluid path;
• and
• an applicator fluidly coupled to the proximal end of the needle assembly, the applicator comprising:
• a first body comprising a first biasing assembly that is coupled to the needle assembly, the first body biasing the needle assembly in a proximal direction with respect to the applicator,
• a second body comprising:
• a syringe chamber having a needle connector port on a proximal end thereof that is fluidly coupled to the needle assembly, and
• a syringe plunger disposed within the syringe chamber at a distal end thereof and movable within the syringe chamber, and
• a second biasing assembly that is coupled between the first body and the second body, the second biasing assembly biasing the syringe plunger at the distal end of the syringe chamber.

A device comprising:

• a needle assembly for which a trajectory is set through a pleural space towards a target at a known distance, wherein the trajectory is maintained while advancing the needle assembly,
• wherein the needle assembly is advanced at a first rate through the pleural space to the known distance;
• and
• wherein a force is applied onto a proximal end of the needle assembly in a distal direction, the force simultaneously injecting a substance at a second rate.
