The carotid artery, which is located in the neck, supplies the brain with oxygenated blood. A carotid artery vascular clamp will likely be used during surgery to treat a brain aneurysm. A vascular clamp is a device surgeons use to prevent blood flowing into areas that are being operated on. They are also able to stem the flow of blood from severed or ruptured vessels. The vascular clamps are manufactured in a variety of shapes and materials, typically high-grade surgical stainless steel and durable plastics.
Vascular Tone. Vascular tone refers to the degree of constriction experienced by a blood vessel relative to its maximally dilated state. All arterial and venous vessels under basal conditions exhibit some degree of smooth muscle contraction that determines the diameter, and hence tone, of the vessel. Basal vascular tone differs among organs.
