Diamond-like carbon thin film with controlled zeta potential for medical material application
Yuki Nitta,Keishi Okamoto,Tatsuyuki Nakatani,Hideo Hoshi,Akihiko Homma,Eisuke Tatsumi,Yoshiyuki Taenaka +6 more
TL;DR: In this paper, a diamond-like carbon (DLC) thin film was applied as a biocompatible material and functional groups such as amino and carboxyl groups were added to the surface of the thin film by plasma surface treatment.
Journal ArticleDOI
At Least Thirty‐Four Days of Animal Continuous Perfusion by a Newly Developed Extracorporeal Membrane Oxygenation System without Systemic Anticoagulants
Tomohiro Nishinaka,Eisuke Tatsumi,Yoshiyuki Taenaka,Nobumasa Katagiri,H. Ohnishi,K Shioya,T. Fukuda,M. Oshikawa,K. Sato,Tomonori Tsukiya,Akihiko Homma,Yoshiaki Takewa,Hisateru Takano,Masaki Sato,Susumu Kashiwabara,Hidenori Tanaka,Kazunari Sakai,Toshiaki Matsuda +17 more
TL;DR: This ECMO system showed potential for long-term cardiopulmonary support with minimal or no use of systemic anticoagulants and thrombus formation was hardly observed in the ECMO systems except in the casing margins of the oxygenator.
Journal ArticleDOI
Up to 151 days of continuous animal perfusion with trivial heparin infusion by the application of a long-term durable antithrombogenic coating to a combination of a seal-less centrifugal pump and a diffusion membrane oxygenator.

TL;DR: A new coating material for medical devices that delivers high antithrombogenicity and long-term durability was applied to an extracorporeal membrane oxygenation (ECMO) system, including the circuit tube, cannulae, a seal-less centrifugal pump, and a diffusion membrane oxygenator to realize prolonged cardiopulmonary support with trivial anticoagulant infusion.
Journal ArticleDOI
Morphological changes of the arterial systems in the kidney under prolonged continuous flow left heart bypass.
H. Ohnishi,Tsuyoshi Itoh,Tomohiro Nishinaka,E. Tatsumi,T. Fukuda,M. Oshikawa,K Shioya,Tomonori Tsukiya,Yoshiaki Takewa,Akihiko Homma,K. Uesho,K. Sato,H. Takano,Yoshiyuki Taenaka +13 more
TL;DR: It is concluded that prolonged continuous flow left heart bypass causes proliferation of SMCs and/or SMC-like cells in the afferent arterioles and their perivascular tissue.
Journal ArticleDOI
The National Cardiovascular Center Electrohydraulic total artificial heart and ventricular assist device systems : Current status of development
Eisuke Tatsumi,Yoshiyuki Taenaka,Akihiko Homma,Tomohiro Nishinaka,Yoshiaki Takewa,Tomonori Tsukiya,H. Ohnishi,M. Oshikawa,Yukitoshi Shirakawa,Yukihide Kakuta,K Shioya,Nobumasa Katagiri,Toshihide Mizuno,Tadayuki Kamimura,Hisateru Takano,Kinji Tsukahara,Katsuya Tsuchimoto,H Wakui,Hideaki Yamaguchi +18 more
TL;DR: In vitro testing demonstrated maximum output more than 9 L/min and more than 13% maximum efficiency and results indicate that the EHTAH and EHVAD have the potential to be totally implantable systems.
