embolizer

An embolizer is a medical device or substance used in a medical procedure called embolization. This procedure involves intentionally blocking blood flow in a specific blood vessel. Embolizers are introduced into the bloodstream, typically through a catheter, and guided to the target vessel. Once in place, they obstruct the vessel, thereby reducing or stopping blood flow to a particular area.

The types of embolizers vary widely, including microscopic particles, coils, wires, balloons, or liquid agents. The choice of embolizer depends on the size and type of blood vessel being treated, as well as the underlying medical condition. For instance, detachable coils are often used to close off aneurysms or arteriovenous malformations, while liquid agents might be employed to block tumor blood supply.

Embolization is utilized for a range of medical conditions. It can be used to treat bleeding from trauma or surgery, to shrink tumors by cutting off their blood supply before surgery or as a primary treatment, and to manage conditions like uterine fibroids or varicose veins. It is also used to treat certain types of stroke by blocking abnormal blood vessels. The procedure is generally performed by interventional radiologists or vascular surgeons.
