SeaStar Medical Holding Corporation is a commercial-stage medical technology company. The Company is focused on developing extracorporeal therapies to reduce the consequences of hyperinflammation on vital organs. The Company's technologies rely on science to provide life-saving solutions to critically ill patients. The Company develops and commercializes cell-directed extracorporeal therapies that target the effector cells that drive systemic inflammation, causing direct tissue damage and secreting a range of pro-inflammatory cytokines that initiate and propagate imbalanced immune responses. The Company uses its Selective Cytopheretic Device (SCD) technology platform to clinically validate several acute organ injury indications, including kidneys and lungs. Its investigational SCD is an extracorporeal synthetic membrane device designed to integrate into existing continuous renal replacement therapy (CRRT) systems that are commonly installed in hospitals throughout the United States.
