Abstract: This invention relates to an aqueous solution for preserving and rinsing organs to be transplanted comprising: sodium (Na+) ions at a concentration between 30 and 150 mmol·L?1; potassium ions (K+) at a concentration between 10 and 40 mmol·L?1; polyethylene glycol with a molecular weight of 35,000 g·mol-1 (PEG 35000) at a concentration between 2 and 5 g·L?1.

Abstract: A quantification device for the level of lipids and/or proteins present within hepatic tissues. The Device includes: a light source, having at least one vacuum tungsten lamp with a total power of between 0.5 and 2 watts, with a total brightness of between 1000 and 2000 lumens and a total color temperature of between 6000 and 10000 degrees Kelvin; a photosensitive sensor having a sensitivity wavelength of between 800 nm and 2450 nm, configured to capture the light emitted from the light source after diffraction within liver tissues; means for extracting a diffraction spectrum of the light according to an image captured by the photosensitive sensor; and means for analyzing the spectrum in order to determine a level of lipids and/or proteins.

Abstract: A perfusion pump system for providing perfusate to an organ of a human body includes an actuator coupled to a pump to provide an actuating force to the pump. The pump includes an outlet for providing a perfusate to an organ coupled to the pump and an inlet for receiving the perfusate. The pump is configured to provide a pulsatile pumping force to the perfusate via a pumping stroke in response to the actuating force. The pumping stroke is followed by a return stroke. The pumping stroke causes the pump to collapse to force a flow of the perfusate through the outlet to the organ. The pump collapses in the direction of the flow of the perfusate. The return stroke allows the perfusate to enter the pump through the inlet and the return stroke of ways providing the perfusate through the outlet.
