What is it?
The XVIVO Perfusion System (XPS™) with STEEN Solution™ is intended to be used on donor lungs prior to transplantation in patients with end-stage lung disease.
The XPS™ with STEEN Solution™ consists of the XPS™ Perfusion Cart Hardware, fluid path and non-fluid path disposables, XPS™ Cart Software, and STEEN Solution™. The XPS™ System is responsible for housing the organ for preservation, providing an environment close to body temperature, and perfusing the organ with the STEEN Solution™. The STEEN Solution™ is a clear, sterile, non-pyrogenic (does not cause fever), non-toxic physiological salt solution containing human serum albumin (HSA) and dextran 40 that is designed for use as a temporary, continuous machine perfusion solution for assessment of isolated lungs after removal from the donor.
How does it work?
The XPS™ System warms the donor lungs to near normal body temperature and continuously flushes the lung tissue with the STEEN Solution™, which preserves the lungs and removes waste products. The XPS™ System also ventilates the lungs, which oxygenates the cells and makes it possible for the transplant team to examine the airways of the lungs with a bronchoscope. Donor lungs can stay in the machine for up to five (5) hours; during this time the transplant team can examine the lungs and evaluate their function. If the lungs meet certain functionality criteria, and pass the transplant surgeon’s examination, they aretransplanted into a recipient.
When is it used?
The XPS™ System with STEEN Solution™ Perfusate is used only on previously unaccepted donor lungs that will be transplanted into a patient with end-stage lung disease.
What will it accomplish?
The use of XPS™ System with STEEN Solution™ Perfusate may increase the donor pool by allowing the safe transplantation of initially unacceptable donor lungs. This includes:
- Allowing time for the lung(s) to re-establish their normal condition in an optimized environment;
- Restoring physiologic problems caused by neurogenic pulmonary edema (e.g., electrolytic balance, colloid-osmotic pressure, and temperature);
- Diluting and filtering away any remaining donor blood and/or clots still in the lung(s);
- Allowing for re-expansion of atelectatic lung areas;
- Allowing time to assess and clean/suction bronchial secretions; and
- Facilitating perfusion of the pulmonary micro-vasculature with the use of dextran in the STEEN Solution™ Perfusate.
When should it not be used?
There are currently no known reasons to not use the XPS™ System with STEEN Solution™ Perfusate on previously unaccepted lungs for transplantation into patients.
