Patent number: 11917991Abstract: Electrode systems have been developed for use in perfusion systems to measure the electrical activity of an explanted heart and to provide defibrillation energy as necessary. The perfusion systems maintain the heart in a beating state at, or near, normal physiological conditions; circulating oxygenated, nutrient enriched perfusion fluid to the heart at or near physiological temperature, pressure and flow rate. These systems include a pair of electrodes that are placed epicardially on the right atrium and left ventricle of the explanted heart, as well as an electrode placed in the aortic blood path.Type: GrantFiled: May 21, 2019Date of Patent: March 5, 2024Assignee: TRANSMEDICS, INC.Inventors: Waleed H.

Publication number: 20200352155Abstract: Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.Type: ApplicationFiled: July 30, 2020Publication date: November 12, 2020Inventors: Robert FISHMAN, Robert HAVENER, Ihab Abdel FATTAH, Anas ABDELAZIM, Scott NEWELL, Thomas H.
