A kidney can only survive 24‑36 hours on ice. A heart, 4‑6 hours. That forces transplants to be done at odd hours, with surgeons on call. But new preservation technologies are extending that window. The US transplantation market research study shows that organ preservation is a $1 billion sub‑market and growing fast. Normothermic machine perfusion (keeping the organ warm and pumping with blood) can double viability time.

What's next? Cryopreservation — freezing organs without ice damage. If solved, we could bank organs for months, like blood. The US transplantation market trends highlight that the fastest‑growing application is tissue transplantation (corneas, heart valves, skin) — these can already be frozen and banked for years.

But challenges remain: ice formation, thawing damage, and cost. A single perfusion device costs $50k‑$200k. Still, for a liver worth $300k, it's a bargain.

The bottom line: better preservation means better organs, more transplants, and fewer deaths. This is a quiet revolution, but it's saving lives every day.
