Sakota D, Kosaka R, Nagaoka E, Ohuchi K, Tahara T, Arai H, et al.
J Heart Lung Transplant
. 2023 Mar;
42(6):707-715.
PMID: 36931988
Background: For normothermic ex vivo heart perfusion (EVHP), a resting mode and working mode have been proposed. We newly developed a left ventricular assist device (LVAD) mode that supports heart...

Transplantation
. 2022 Dec;
107(3):628-638.
PMID: 36476980
Background: Increased extravascular lung water during ex vivo lung perfusion (EVLP) is associated with ischemia reperfusion injury and poor pulmonary function. A non-invasive technique for evaluating extravascular lung water during...

Kosaka R, Sakota D, Niikawa H, Ohuchi K, Arai H, McCurry K, et al.
Artif Organs
. 2022 Mar;
46(8):1522-1532.
PMID: 35230734
Background: Thermography is a noninvasive technology to detect low temperatures in poorly circulated areas. In ex vivo lung perfusion (EVLP), lungs are rewarmed to body temperature during the initial 1 ...

Sakota D, Kosaka R, Niikawa H, Ohuchi K, Arai H, McCurry K, et al.
Biomed Opt Express
. 2022 Feb;
13(1):328-343.
PMID: 35154874
Ex vivo lung perfusion (EVLP) is an emerging tool to evaluate marginal lungs in lung transplantation. However, there is no objective metric to monitor lobular regional oxygenation during EVLP. In...

J Artif Organs
. 2022 Jan;
25(3):195-203.
PMID: 35088287
Plasma skimming can exclude red blood cells from high shear regions in the gaps formed by hydrodynamic bearings in rotary blood pumps. We investigated the effect of the gap size...

Oota-Ishigaki A, Yamane T, Sakota D, Kosaka R, Maruyama O, Nishida M
Int J Artif Organs
. 2021 Oct;
45(4):431-437.
PMID: 34661490
Low-flow blood pumps rated under 1 L/min are emerging for new medical applications, such as hemofiltration in acute use. In those pumps, platelet adhesion and aggregation have to be carefully...

Oota-Ishigaki A, Maruyama O, Sakota D, Kosaka R, Hijikata W, Nishida M
Int J Artif Organs
. 2021 Jun;
44(10):687-693.
PMID: 34058917
Blood pumps are often used for hemofiltration in patients with renal failure. To design effective centrifugal blood pumps for hemofiltration, it is important to suppress clogging caused by platelet aggregation....

Heart Vessels
. 2021 Mar;
36(6):890-898.
PMID: 33686554
A survey conducted by Abiomed, Inc. revealed that 10 of 60 patients who received ventricular assistance via the AB5000 ventricular assist device (VAD) experienced hemolysis. The present study was conducted...

J Artif Organs
. 2021 Jan;
24(2):157-163.
PMID: 33428006
We have developed a hydrodynamically levitated centrifugal blood pump. In the blood pump having hydrodynamic bearings, the narrow bearing gap has a potential for high hemolysis. The purpose of the...

Int J Artif Organs
. 2020 Dec;
44(8):565-573.
PMID: 33300399
Introduction: Real-time, non-invasive monitoring of thrombus formation in extracorporeal circuits has yet to be achieved. To address the challenges of conventional optical thrombus detection methods requiring large devices that limit...
