Abstract

An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.

Claims

1. An apparatus for holding an organ for at least one of perfusion, storage, assessment and transport of the organ, comprising:

a portable housing;

an organ supporting surface configured to support an organ within said housing, wherein the portable housing is configured to be received by at least one of an organ perfusion device, an organ transporter and an organ assessment device, and includes one or more openings configured to allow tubing to be connected to the organ by way of the one or more openings, and wherein a bottom portion of the housing is liquid-tight; and

a first lid and a second lid for the housing, wherein at least one of the first lid and the second lid is openable without exposing an interior of the portable housing and the first lid and the second lid are attachable to the portable housing.

2. An apparatus for holding an organ for at least one of perfusion, storage, assessment and transport of the organ, comprising:

a portable housing;

an organ supporting surface configured to support an organ within said housing, wherein the portable housing is configured to be received by at least one of an organ perfusion device, an organ transporter and an organ assessment device, and includes one or more openings configured to allow tubing to be connected to the organ by way of the one or more openings, and wherein a bottom portion of the housing is liquid-tight; and

a first lid and a second lid for the housing, wherein the second lid is interior to the first lid and the first lid and the second lid each are configured to form a seal with the portable housing.

3. An apparatus for holding an organ for at least one of perfusion, storage, assessment and transport of the organ, comprising:

a portable housing;

an organ supporting surface configured to support an organ within said housing, wherein the portable housing is configured to be received by at least one of an organ perfusion device, an organ transporter and an organ assessment device, and includes one or more openings configured to allow tubing to be connected to the organ by way of the one or more openings, and wherein a bottom portion of the housing is liquid-tight; and

a first lid and a second lid for the housing, wherein at least one of the first lid and the second lid is openable without exposing an interior of the portable housing and the first lid and the second lid each are configured to form a seal with the portable housing.
