FDA clears r4 Vascular Vector PTA balloon catheters

The US Food and Drug Administration (FDA) has cleared r4 Vascular's high pressure Vector percutaneous transluminal angioplasty (PTA) balloon catheters for treating vascular narrowings lesions and blockages.

Patent pending Vector PTA balloon catheters, available in 28 sizes, can withstand up to 30 atmospheres of pressure and are radiopaque when deflated or inflated.

By utilizing catheter shaft technology, high-pressure PTA balloons are used to keep hemodialysis access sites open for dialysis treatments, to restore blood flow in the legs, to dilate narrowings in renal arteries as well as dilate lesions in other vessels throughout the body.

Vector balloon catheter, also including radiopaque stripes on the balloon, helps physicians not to use viscous contrast media to visualize the balloon under x-ray fluoroscopic guidance and may use low-viscosity saline to reduces inflation/deflation time up to 50%.
