Experimental: OCS
OCS Lung Preservation
Device: OCS Lung Preservation
OCS Lung Preservation
Other Name: OCS Lung Transplant

Primary Outcome Measures :
  1. Patient Survival [ Time Frame: 30 days post transplantation ]
    Patient survival at Day-30 post-transplantation and at initial hospital discharge post-transplantation, whichever occurs later.

  2. Donor Lung Utilization Rate [ Time Frame: Immediately at Transplantation ]
    Donor lung utilization rate, defined as the number of donated lungs instrumented on OCS™ that meet inclusion/exclusion criteria for the trial and acceptance criteria for transplantation after OCS™ Lung assessment divided by the total eligible donor lungs instrumented on the OCS™ Lung System.

Secondary Outcome Measures :
  1. Primary Graft Dysfunction Grade 3 [ Time Frame: within 72 hours pos-transplant ]
    Incidence of Primary Graft Dysfunction Grade 3 on post-operative day 3
