Medtronic Japan releases resolute Onyx drug-eluting stent
Medtronic Japan Co., Ltd. (head office, Minato-ku, Tokyo; president, Tony Semedo) will release a drug-eluting stent Resolute OnyxTM Coronary Stent System (hereafter, Resolute Onyx; Medical Device Approval No. 22900BZX00186000; product name, Resolute OnyxTM Coronary Stent System) on July 10th. In addition to its abundant clinical performance, the Resolute Onyx offers superior deliverability to that of its predecessor Resolute IntegrityTM(initial sales in Japan, August 2012).
“With the new Core Wire Technology, the Resolute Onyx aims for improved deliverability in complex lesions, enhanced conformability to the vessel wall and greater radiopacity for more accurate stent placement,” said one of the investigators of the RESOLUTE Japan Study Shigeru Saito, M.D., assistant director of Shonan Kamakura General Hospital/cardiology and catheterization laboratories. “The Resolute Onyx will be one of the new standards of durable polymer drug-eluting stent (DES) in Japan.”
With the Core Wire Technology of Resolute Onyx, a metallically dense, radiopaque inner core is incorporated within the cobalt alloy wire to enhance visibility for accurate stent placement. The Core Wire Technology also enables thinner struts while maintaining structural strength to radially support the blood vessel. The Continuous Sinusoid Technology originally used in the Resolute Integrity is a unique Medtronic method of stent manufacturing, which involves forming a single strand of cobalt alloy wire into a sinusoidal wave to construct a stent. This enables a continuous range of motion, flexible and superior conformability to the vessel wall, and good stent apposition. The Core Wire Technology is another new technology developed following the Continuous Sinusoid Technology.

[About drug-elution stent (DES)]
DES is used in percutaneous coronary intervention (PCI), which is a less invasive treatment of ischemic heart disease. DES is placed to widen the narrowed part of coronary artery (a lesion where the blood flow is decreased because of advanced arteriosclerosis) that sends blood to the heart, and elute drug substance in the area to prevent restenosis.
