  • Publication number: 20120183945
    Abstract: Method and device for treatment of a heart after harvesting and before transplantation. The device includes a container intended to comprise the heart; a first line for connection to an aorta of the heart; a fluid circuit comprising an oxygenator for oxygenating said fluid and a heater/cooler for regulating the temperature of said fluid; and a pump for perfusion of said fluid through the coronary blood vessels of the heart. The fluid includes an oncotic agent exerting an oncotic pressure larger than about 30 mmHg; and is cardioplegic by comprising a potassium concentration, which is between 15 mM and 30 mM. A control device is arranged for controlling the pump to perform said perfusion intermittently, whereby the perfusion time is less than half of the cycle time. The perfusion is performed at a pressure, which is at least 15 mmHg and at least 15 mmHg lower than said oncotic pressure.

  • Publication number: 20110065169
    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.

  • Publication number: 20110003275
    Abstract: A method and system for organ evaluation and preservation for connection to an organ and for recirculation of a perfusion medium there through. The system comprises a first collection device for collection of the perfusion medium perfused through the organ and a second collection device arranged in an outlet conduit from the first collection device. 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.

  • Patent number: 7226427
    Abstract: Improved procedures for cardiopulmonary resuscitation of a victim of cardiac arrest are provided. In the resuscitation, the victim's chest is mechanically compressed and decompressed to stimulate the heart. The victim is induced to inspire and expire against insufflating breathing gas during the chest compression/decompressions. The breathing gases are adduced under pressure to promote the development of a positive coronary perfusion pressure. Electro-stimulation of the heart can be carried after positive coronary perfusion pressures have been achieved. The electro-stimulation can be defibrillation or heart pacing or both. The chest compression/decompression cycles and the electro-stimulation measures are synchronized to promote sufficiently body circulation of oxygenated blood in a subject suffering from cardiac arrest. Medical equipment systems are provided for implementing the CPR procedures.

  • Patent number: 6524333
    Abstract: The invention relates to a device for therapeutical treatment of a blood vessel. It comprises in combination a stent, a balloon catheter for the insertion of the stent into a blood vessel, and a generator for generating ultrasound. The stent can be expanded radially and is of such construction that it is caused to vibrate and/or develop heat when exposed to ultrasound. Inserted into the blood vessel the stent can be expanded by means of the balloon catheter to engage the inside surface of the blood vessel in order to be left in the expanded condition as an inside lining in the blood vessel after the balloon catheter having been withdrawn from the blood vessel. Energy is transferred wirelessly by means of ultrasound generated by the generator, from an extra-corporeal position to the stent as located in the blood vessel engaging the inside surface thereof.
