Peripheral Artery Disease


Our proprietary, self-developed and self-manufactured FocusLine® PTA balloon dilation catheter is our first peripheral vascular product approved by the NMPA.  We also have three other peripheral vascular product

Peripheral artery diseases, or PAD, refer to diseases of blood vessels located outside of the heart or brain, which develops when plaque clogs or narrows arteries that deliver blood to the arms, legs and internal organs such as the stomach or kidneys.  PAD is the third leading cause of atherosclerotic vascular morbidity after a coronary heart disease or stroke.  In China, PAD is increasingly prevalent driven by the aging population and increasing public awareness.  Early detection and treatment can prevent heart attacks, stroke, mini-stroke, leg ischemia and possible amputation.

Treatment of PAD

With the development of peripheral interventional procedures, vascular intervention has become the first choice or combination therapy for many specific diseases. The current interventional therapies include balloons, stents and atherectomy. Peripheral artery balloon catheters, such as the percutaneous transluminal angioplasty (PTA) balloon catheter and drug-coated balloon (DCB) catheter, are a main type of medical devices used in the peripheral interventional procedures.  PTA balloon catheter has an inflatable balloon at its tip which is used during a minimally invasive catheterization procedure.  This procedure is intended to enlarge a narrowed vessel opening.  The deflated balloon is positioned at the narrowed space, inflated for a short period of time, and then deflated.
