Unlike angioplasty and stents, which push plaque into the vessel wall,<unk>  cuts plaque from the wall of the artery. While<unk>  is usually employed to treat arteries it can be used in veins and vascular bypass grafts as well.<unk>  falls under the general category of percutaneous revascularization, which implies re-canalizing blocked vasculature via a needle puncture in the skin. The most common access point is near the groin through the common femoral artery (CFA). Other common places are the brachial artery, radial artery, popliteal artery, dorsalis pedis, and others. There are four types of<unk>  devices: orbital, rotational, laser, and directional. The decision to use which type of device is made by the interventionist, based on a number of factors. They include the type of lesion being treated, the physician's experience with each device, and interpretation of the devices' risks and effectiveness, based on a review of the medical literature. Directional<unk>  is an intravascular procedure guided by optical coherence tomography termed as lumivascular<unk> .
