Systems, devices and methods for reconstituting therapeutic powders, mixing precursor solutions, and expressing sealants for controlling bleeding and sealing fluid and air leaks

A sealant delivery system comprising:

• a syringe assembly including side-by-side first and second syringes, said first syringe having a first fluid chamber and said second syringe having a second fluid chamber;
• a vial assembly coupled to a distal end of said syringe assembly, said vial assembly including side-by-side first and second vials;
• said first vial having a proximal end that is aligned with a distal end of said first syringe, said first vial including a first vial opening at the proximal end thereof that is closed by a first sealing membrane;
• said second vial having a proximal end that is aligned with a distal end of said second syringe, said second vial including a second vial opening at the proximal end thereof that is closed by a second sealing membrane;
• said vial assembly including a first piercing element located between the distal end of said first syringe and the proximal end of said first vial, said first piercing element having a first piercing spike projecting from a distal end thereof, said first piercing element being moveable between a retracted position in which said first piercing spike is located on a proximal side of said first sealing membrane and an extended position in which said first piercing spike passes through said first sealing element for piercing said first sealing membrane to provide first fluid communication between said first fluid chamber of said first syringe and said first vial;
• and
• said vial assembly including a second piercing element located between the distal end of said second syringe and the proximal end of said second vial, said second piercing element having a second piercing spike projecting from a distal end thereof, said second piercing element being moveable between a retracted position in which said second piercing spike is located on a proximal side of said second sealing membrane and an extended position in which said second piercing spike passes through said second sealing element for piercing said second sealing membrane to provide second fluid communication between said second fluid chamber of said second syringe and said second vial.
