Method For Ex-Vivo Organ Care And For Using Lactate As An Indication Of Donor Organ Status

US Patent:
8304181, Nov 6, 2012
Filed:
Apr 25, 2007
Appl. No.:
11/790405
Inventors:
Waleed Hassanein - North Andover MA, US
Tamer Khayal - North Andover MA, US
Paul Lezberg - Westford MA, US
Giovanni Cecere - Needham MA, US
Dennis Sousa - Wakefield MA, US
Elizabeth Hansen - Portsmouth NH, US
Assignee:
Transmedics, Inc. - Andover MA
International Classification:
A01N 1/02
US Classification:
435 11
Abstract:
The invention provides, in various embodiments, systems, devices and methods relating to ex-vivo organ care. In certain embodiments, the invention relates to maintaining an organ ex-vivo at near-physiologic conditions. The present application describes a method for using lactate measurement in the arterial and the venous blood lines of the Organ Care System Heart perfusion device to evaluate the: 1) The overall perfusion status of an isolated heart and 2) The metabolic status of an isolated heart and 3) the overall vascular patency of an isolated donor heart. This aspect of the present invention uses the property of myocardial cell's unique ability to produce/generate lactate when they are starved for oxygen and metabolize/utilize lactate for energy production when they are well perfused with oxygen.

Systems For Monitoring And Applying Electrical Currents In An Organ Perfusion System

US Patent:
2008023, Sep 25, 2008
Filed:
Jul 6, 2007
Appl. No.:
11/822495
Inventors:
Waleed Hassanein - North Andover MA, US
Richard Bringham - North Andover MA, US
Robert Havener - Lynnfield MA, US
Vincent Lambert - Salisbury MA, US
Burt Ochs - Andover MA, US
Assignee:
TransMedics, Inc - Andover MA
International Classification:
A61N 1/04
US Classification:
607 4
Abstract:
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.

Assignee:
TransMedics, Inc. - Andover MA
International Classification:
A01N 1/02
US Classification:
4352841, 435 12
Abstract:
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.
