Sendai, Japan, 06 December 2023 — Recently, MicroPort® NeuroTech™ announced that the NUMEN™ Coil Embolization System (NUMEN™) completed its first batch of clinical implantations in Japan on 10 October. Within three weeks following this announcement, 28 procedures were successfully carried out in 22 Japanese hospitals, receiving positive feedback overall. Adding to this achievement on October 1, NUMEN™ received approval from Japan's Ministry of Health, Labour and Welfare (MHLW) for inclusion in public medical insurance.
The first implantation was jointly performed at Kohnan Hospital in Japan by Dr. Sakata, Dr. Hariu, and Dr. Honma. The patient, a 90-year-old woman, was preoperatively diagnosed with an irregularly shaped ruptured aneurysm in the ICA-PComA segment, measuring approximately 7.8 x 6.5 mm. The surgeons opted for a simple coil embolization approach, using NUMEN™ for both the embolization filling and finishing stages, with a total of four NUMEN™ coils implanted (NUMEN™ MicroFinish 3 x 6 mm, 2.5 x 4 mm, 1.5 x 2 mm, 1.5 x 2 mm). During the procedure, NUMEN™ was noted for its smooth handling and ease of navigating into residual spaces. With successful and straightforward detachment, NUMEN™ achieved effective aneurysm occlusion. After the procedure, the medical team highly praised NUMEN™ for its smooth deliverability, good space seeking capabilities, microcatheter stability during the finishing stages, and its simple, rapid, and reliable detachment process, enabling stable aneurysm embolization.1
To date, both NUMEN™ and the Numen FR™ Detachment System have secured approval in China, the EU, the USA, Korea, Brazil, and Japan. They have successfully completed clinical implantation in several countries across Asia-Pacific, North America, and Europe. The recent achievement in Japan marks NUMEN™'s introduction into the 16th country or region. Its inclusion in Japan’s medical insurance system means NUMEN™ can benefit more local patients while significantly reducing financial burden. This is a significant step in NeuroTech™’s ongoing effort to expand global markets.
MicroPort® NeuroTech™ continues to enhance its business operations and advance medical R&D. Looking ahead, MicroPort® NeuroTech™ aims to provide more comprehensive solutions for patients worldwide suffering from cerebral vascular diseases.
About NUMEN™
As a new generation of electrolytically detachable coils, NUMEN™ is characterized by its stable basket formation and dense embolization. Its pusher wire features a unique micro-loop design that allows for electrolytic detachment of the coil, potentially reducing surgery time. Made from ultra-fine platinum-tungsten wire and a distinctive three-dimensional structure, NUMEN™ balances softness with support, significantly reducing pressure on aneurysm walls and ensuring embolization safety. Additionally, NUMEN™ offers 177 different models across three series, providing physicians with a diverse range of choices for precise aneurysm embolization.
