Abstract: An examination device for a heart. An afterload device connected to the aorta provides a counter-pressure by an annular space delimited between a rigid cylinder and an elastic tube inserted in the rigid cylinder. The annular space comprises a compressible medium, such as air, nitrogen gas or carbon dioxide and is connected to a reservoir providing a predetermined pressure corresponding to a diastolic pressure. The reservoir is connected to the annular space via a restriction and a back-flow valve. During diastole, the annular space is inflated by the reservoir and provides a diastolic counter pressure for providing coronary flow. During systole, the ejected fluid from the heart ventricle displaces the medium inside the annular space through the restriction to the reservoir, thereby removing energy from the fluid. The compressible medium forms a compliance. Also, there is a preload device comprising a vertical collapsible tube for preload of the atrium.

Abstract: An apparatus for enclosing an organ after harvesting and before implantation, having; a vessel enclosing a fluid, a connection tube for connecting a circulation hose to the organ for passing a fluid to the organ by a pump, and a degassing hose extending from the connection tube to the vessel. A pinch valve is arranged in the degassing hose. During a degassing phase, the pinch valve is opened to allow fluid flow from the pump, via the circulation hose to the connection tube and via the degassing hose to the vessel for expelling air entrapped in the fluid flow system. A balloon is arranged to prevent fluid flow via the connection tube to the organ during the degassing phase. A sterility arrangement closes the vessel at the top and may be replaced by further sterility arrangements without compromising the sterility.

Abstract: A method and device for providing ventilation gas to a patient during cardiopulmonary resuscitation. The device comprises: a gas source for supplying oxygen to the bronchi of the patient and a switch valve for initiating and terminating the gas supply. The switch valve is operated synchronous with the cardiopulmonary resuscitation cycle so that the switch valve operates with the same cycle as the cardiopulmonary resuscitation cycle but off-set in relation to the cardiopulmonary resuscitation cycle. The gas supply is initiated between 25% and 2% of the cycle time before the start of a compression stroke and is terminated between 2% and 30% of the cycle time after the start of a compression stroke. Alternatively, the gas supply is initiated between 25% and 48% of the cycle time after the termination of a compression stroke and is and terminated between 52% and 80% after the termination of a compression stroke.

Abstract: A vessel for housing an organ such as lungs from a mammal ex-vivo, for evaluation or preservation. A liquid solution suitable for evaluation or preservation of the lungs surrounds the organ, at least partly. The solution is circulated via an outlet and an inlet. Two pressure chambers are arranged between the walls of the vessel and the organ. A gas is introducible to the pressure chamber in order to expand the pressure chamber for occupying the spaces surrounding the organ. Then, the pressure inside the pressure chambers is increased in order to push the solution to a higher level so that the organ is immersed in the solution without necessitating addition of further solution. Alternatively, the vessel is exposed to an under pressure and the pressure chambers are open to the atmosphere. In a further alternative embodiment, a solution collection space has variable volume.

A pump passes the perfusion medium from the second collection device to the organ via a conduit. A flow regulation device, such as an on-off clamp, is arranged in the outlet conduit for controlling the flow in the outlet conduit in order to maintain a constant fill of the second collection device as measured by a fluid level sensing device.
