Saving Organs.
Limbs. Lives.

More than half of all donated organs are rejected because they cannot reach patients fast enough.

We’re about to change that by extending viability from 4 to 24 hours.

ULiSSES™ Wins Create the Future Grand Prize

Out of 700 entries from 60 countries, VPS’s innovative device takes design award.

See why the ULiSSES™ device is gaining worldwide attention.

There’s not enough time for donated organs.

Right now, most organs are rejected because they can’t reach patients in time.

Let’s change the organ transplant world.

By extending the viability of organs from 4 hours to 24 hours, more organs will be available for transplant, and more lives will be saved.

Why 24 hours is transformational

Preserving Limbs in 21st Century

For those that are interested in learning more about the state of the art in machine perfusion for kidneys, the following article is available:
Machine perfusion preservation versus static cold storage for deceased donor kidney transplantation – Tingle, SJ – 2019 | Cochrane Library

This paper, authored by the inventor of ULiSSESTM, illustrates the advantages of oxygenated perfusion. We are excited to note that the ULiSSESTM technology is quite different from what is illustrated in this paper. It is much more efficient, and represents a dramatic improvement in the ability of the device to keep organs and limbs alive. Patent applications are pending.
