Inspirex™ Lung
Bioengineered human lung graft for life-saving transplantation
Inspirex lung technology advances a new approach to organ transplantation through bioengineered human lung grafts with whole organ functionality and anatomical compatibility.

PRESSING NEED
More lung grafts for transplant
The wait for a lung transplant is a race against time. Many patients spend years on the transplant waiting list while facing rejection, complications, or progressive disease before a donor organ becomes available.
Inspirex™ lung advances a potential human lung transplant alternative for patients with limited transplant options and ongoing organ shortages.
MEDICAL BREAKTHROUGH
Inspirex™ Lung
Generated through our xenogeneic cross-circulation platform, Inspirex™ Lung is a bioengineered lung graft for transplant with whole organ functionality and anatomical compatibility for clinical transplantation.
The platform supports ongoing research in xenogeneic lung transplant science, organ rehabilitation, and regenerative transplantation medicine.
IMPACT
Transforming the future of lung transplantation
Lung transplant volumes have increased only incrementally over the past two decades despite growing patient demand.
The availability of Inspirex™ Lung may help expand access to transplantation, increase the number of viable donor lungs, and reduce lung transplant waitlist mortality in the United States.
