VI°Port™
VI°Port Liver Preservation System
Designed to maintain the liver within 4–8°C for the full preservation window, with the most precise and consistent temperature control available.
Precise and advanced hypothermic preservation at a sustainable price point.
Challenges in Liver Preservation
Ice storage risks freezing injury
Static ice storage can bring preservation solution below its freezing point, causing intracellular ice crystal formation and organelle membrane disruption within a standard transport window.1
Ice storage exacerbates ischemic injury
Static ice storage triggers ATP depletion, membrane pump failure, cellular edema, and calcium influx. These processes accelerate hepatocyte damage during preservation.2
Marginal & DCD livers are inadequately protected
Static ice storage frequently fails to provide sufficient protection for marginal and DCD livers, with many grafts left untransplanted due to preservation insufficiency2
THE IMPORTANCE OF RELIABILITY
Precision, reliability, and monitoring is critical
The liver has no salvage therapies making reliability of preservation technology critical.
HOW ALTERNATIVES FALL SHORT
Alternative devices are costly
Existing preservation and perfusion systems carry a price point that restricts use to select cases.
Introducing VI°Port
Precise temperature maintained by thermal ballast
The thermal ballast works in both directions: absorbing heat when the environment warms and releasing it when temperatures drop. Much like an ocean buffers a coastal town from temperature extremes, it maintains a stable thermal environment around the organ for the duration of transport.

Insulated Chamber
A lightweight, impact-resistant expanded polypropylene (EPP) container that provides durable thermal insulation
02
Thermal Ballast
A molded ballast below the liver cradle helps stabilize temperature and reduces rapid temperature changes.
03
TEMPERATURE DISPLAY
An integrated temperature logger records the liver’s temperature profile during transport
04
Phase-Change Cooling PAcks
PCM-based cooling packs that keep the organ within a tight, optimal temperature range
05
Temperature Probe
A temperature probe embedded in the organ cradle for continuous, real-time monitoring during transport
06
Traferox Mobile App
A Bluetooth app that provides live temperature readings and transport time. Data can be exported and shared.
Monitor Liver Temperature in the Traferox App
The Traferox Bluetooth app provides live temperature readings and transport time throughout the procurement journey. Export and share temperature data over email.
Sustainable Price Point
Approximately 40% less expensive than other hypothermic devices, with the ability to be reset if the liver is not accepted for transplant.
