Decoding the Problem:
Why is there a shortage of Livers?

We create the best possible environment for a liver outside the human body.

Long Term

The only long-term liver perfusion system able to preserve a liver organ for up to 7 days to give every clinician all the time needed.

Organ Assessment & recovery

An ideal physiological environment allows for prolonged continuous /real-time assessment and enables ex-situ organ recovery.

Ease of Use

An advanced control system ensuring a high level of automation with minimal need of supervision. 

Proof of Work

First-in-human transplant following 3 days organ perfusion.

Features

  • Advanced perfusion technology
  • Cutting-edge organ preservation
  • Highly automated system
  • Innovative research and development capabilities

Benefits

  • Ex-situ organ recovery
  • Unmatched Flexibility
  • A new approach to transplantation
  • Perfusion of organs with extended donor criteria
