Apparatus and method for sustaining and evaluating isolated organs
12439910 · 2025-10-14 ·

An organ preservation system having; an organ chamber with a perfusate reservoir, a pump arranged to circulate perfusate, from the reservoir and passes the perfusate through a dialysis filter, oxygenator, and temperature and pressure sensors prior to entering the chamber where an organ is perfused. The organ rests on the platform such that perfusate leaving the organ flows into the perfusate reservoir. The dialysis filter having permeable tubes which allow perfusate constituents to be exchanged with dialysate flowing through the dialysis filter. The dialysate pass through an ion exchange resin removing selected constituents or waste products from the dialysate by absorption by the ion exchange resin. Following waste absorption, the dialysate is recycled to the dialyzer to again remove waste. Removing waste products from the perfusate by dialysis followed by removal of the waste products from the dialysate with the exchange resin, enables dialysate reuse for extended duration.

Cross-circulation platform for recovery, regeneration, and maintenance of extracorporeal organs

Described are systems, methods, and devices relating to normothermic extracorporeal support of an organ, tissue, or bioengineered graft comprising cross-circulation (XC) perfusion for prolonged periods (days to weeks) via an XC perfusion circuit in connection with an extracorporeal host (e.g., animal, patient, organ transplant recipient) are disclosed. The XC perfusion circuit comprises auto-regulation of blood flow based on the trans-organ blood pressure difference between arterial and venous pressure. Recipient support enabled 36 h of normothermic perfusion that maintained healthy lungs with no significant changes in physiologic parameters and allowed for the recovery of injured lungs. Extended support enabled multiscale therapeutic interventions in all extracorporeal lungs. Lungs exceeded transplantation criteria.
