Zylox-Tonbridge

What Zylox-Tonbridge does

Zylox-Tonbridge Medical Technology Co., Ltd. is a Hong Kong-listed medical technology company founded in 2012 and headquartered in Hangzhou, China, that develops, manufactures, and commercializes neurovascular and peripheral vascular interventional medical devices. The company operates a comprehensive product portfolio spanning two core franchises: neurointervention (including the Thrombite clot retriever, Cylone aspiration catheter, Gekko detachable coils, Kylin flow diverter, and various microcatheters and guidewires) and peripheral vascular intervention (including ZenFlow PTA balloon catheters, Zenflex peripheral stent systems, ZYLOX Mammoth large-bore thrombectomy catheters, and ZYLOX Unicorn vascular closure devices). Underlying technology centers on proprietary innovations such as the patented UltraFree drug coating technology, S-shaped helical open-side stent retriever structure, and China's only 12F-18F peripheral thrombectomy catheter.

The company generates revenue primarily through direct hardware sales of medical devices to hospitals and healthcare facilities, supplemented by distribution through over 80 commercial partners across 83 countries and regions. FY2025 revenue reached RMB 1.06 billion (35.1% YoY growth) with net profit of RMB 244 million (143.7% YoY growth), and cumulative procedures using Zylox-Tonbridge products exceeded one million. International revenue surged 115.5% to RMB 48.65 million, reflecting active geographic expansion supported by participation in major medical conferences globally.

In January 2026, Zylox-Tonbridge announced a definitive agreement to acquire Germany-based Optimed Medizinische Instrumente GmbH, a specialist in minimally invasive vascular and endourology devices with a 70+ country sales network, creating a unified global commercial organization spanning R&D, manufacturing, and commercialization. The company holds CE marking for peripheral artery intervention devices, maintains RMB 2.60 billion in total financial resources, and was recognized as Most Honored Company in Extel's 2026 Asia Executive Team Survey in the Healthcare Equipment & Services sector.
