Renal Ex Vivo Interrogation for Viability and ALlocation

Uncovering potential in kidneys that might otherwise go unused.

More insight for OPOs.
More confidence for transplant centers.

What goes into an acceptance decision?

Donor factors

Age, history & KDPI

These estimate risk alone rather than function. [2]

Biopsy

A small view of structure

Sampling, preparation and interpretation vary. [3]

Perfusion data

Flow & resistance

Perfusion measurements while on pumps provide limited information alone. [4]

How can we better assess these kidneys for transplant?

A SNAPshot of a kidney’s true potential.

Our approach pairs oxygenated, sub-normothermic acellular perfusion with functional assessment.

  1. Hard-to-place kidneys

    Kidneys at risk of being discarded are referred for a closer look at their functional potential.

  2. SNAP at REVIVAL

    Oxygenated, sub-normothermic acellular perfusion supports a kidney’s viability while we assess function outside the body.

  3. A second look

    The kidney is returned with a functional assessment, giving transplant teams more information to guide placement decisions.

More informed decisions.
More potential for transplantation.

The REVIVAL
Difference

At REVIVAL, we draw on years of clinical and surgical transplant experience to provide a more complete assessment of organ viability.

Protection

Our perfusate is formulated to maximize renal protection.

Function

Urine output and metabolic function provide a window into how a kidney might perform after transplantation.

Diuretic Challenge

Simulating in vivo diuretic testing for a more complete picture of kidney function.
