Arteries (from Greek á¼ÏÏÎ·ÏÎ¯Î± (artÄria) , meaning windpipe, artery) are blood vessels that carry blood away from the heart.While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries.ystemic arteries are the arteries (including the peripheral arteries), of the systemic circulation, which is the part of the cardiovascular system that carries oxygenated blood away from the heart, to the body arterioles, and then to the capillaries, where nutrients and gases are exchanged.
The Medical Devices Bureau of Health Canada recognizes four classes of medical devices based on the level of control necessary to assure the safety and effectiveness of the device. Class I devices present the lowest potential risk and do not require a licence.
Cleared medical devices: These medical devices are ones that FDA has determined to be substantially equivalent to another legally marketed device. A premarket notification, referred to as a 510(k), must be submitted to FDA for clearance. A 510(k) is most often submitted by the medical device manufacturer. Approved medical devices: Approved medical devices are those devices for which FDA has approved a premarket approval (PMA) application prior to marketing. This approval process is generally reserved for high-risk medical devices and involves a more rigorous premarket review than the 510(k) pathway.
