What Easy Flow does

Easy Flow (Shanghai Easy-Flow Medical Tech Co., Ltd.) is a Shanghai-based medical device company founded in November 2021 by Miao Zhenghua, a former public-company CEO with over 20 years of vascular intervention experience. The company focuses on minimally invasive peripheral vascular intervention products for the Chinese and selected international markets, targeting hospitals with vascular surgery, interventional radiology, cardiology, and nephrology departments. Its portfolio addresses peripheral artery disease (PAD), thrombosis, hemodialysis access complications, peripheral embolization, and venous disease through five product lines organized into arterial intervention, thrombectomy, venous intervention, hemodialysis access, and peripheral embolization categories.

The company's technology stack centers on drug-coated and drug-eluting balloon and stent platforms, with proprietary sirolimus and paclitaxel coating processes (including recrystallization plus ultrasonic spray coating claimed to maintain therapeutic drug concentration in the vessel wall for over 90 days), nitinol-constrained PTA balloon architectures that create alternating pillows and grooves for controlled dilation, hybrid closed-cell/open-cell stent designs, and gradient paclitaxel-fluoropolymer coatings. The mechanical thrombectomy line combines an in-house aspiration system (EF-Salween) with an in-licensed manual thrombectomy kit (EF-Control) from US-based Control Medical Technology. As of December 2025, the company holds more than 70 medical device registration certificates and has commercially launched seven products in China, with EF-OptiPrep additionally registered in Brazil via ANVISA.

Easy Flow generates revenue through direct hardware sales of medical devices to hospitals, with no publicly disclosed pricing and sales cycles tied to clinical validation, hospital procurement, and regional reimbursement. The go-to-market is an enterprise field sales motion anchored on multi-center randomized clinical trials at leading Chinese hospitals (e.g., Shanghai Longhua Hospital, Chongqing Medical University First Affiliated Hospital, Tianjin Medical University General Hospital) and peer-reviewed evidence, supplemented by medical conference participation and KOL engagement. The company has raised over CNY 100 million across an angel round (October 2022, Legend Capital-led) and a Series A+ (April 2025, Shanghai Healthcare Capital-led), with stated use of funds for pre-market clinical trials, regulatory registration, and domestic/international expansion.
