👉 In the context of medicine, a "throat latch" is a medical device that is used to control the flow of medication through an artery or vein. These devices are typically inserted into the skin and attached to a catheter, allowing doctors to deliver medication directly to specific areas of the body without the need for a needle or other invasive procedure. The purpose of this device is to reduce the risk of blood clots and promote the healing process in patients with certain conditions such as heart disease or cancer.
