Vascular Access Devics provide a way of drawing blood or delivering medication and nutrients into the bloodstream on a continual basis. In a vascular access procedure, a special catheter (a long, thin tube) is placed in the body and threaded into a large central chest vein. A vascular access device can be a gentler and more comfortable solution for patients who need intravenous (IV) access for a prolonged period of time (longer than seven to 10 days). A vascular access device can help patients avoid the pain and stress of repeated needle sticks.
