The Guardian catheters utilize CVD's Focus Technology to treat atherosclerosis blocking blood flow within coronary arteries.
In contrast, the Guardian catheters "focalize" the majority of the dilatation force more directly to the lesion site, sparing the surrounding arterial wall from potentially damaging balloon dilatation force.
The Guardian catheters represent another advance in CVD Focus Technology, providing further miniaturization of every component of the catheter device.
In addition, the Guardian catheters are the first CVD products available in the United States using CVD's unique preformed, extended-pressure Focus Balloon Technology.
