angioscopes

An angioscope is a medical instrument used to visualize the inside of blood vessels. It is a type of endoscope, a flexible or rigid tube with a light source and a lens, designed specifically for examining the vascular system. Angioscopes typically feature a very small diameter, allowing them to be inserted into relatively narrow blood vessels, such as arteries or veins.

The primary function of an angioscope is diagnostic. By inserting the device, physicians can directly observe the internal lining of blood vessels, identifying abnormalities such as plaque buildup (atherosclerosis), blood clots (thrombosis), or narrowing of the vessel lumen (stenosis). This direct visualization can provide more detailed information than non-invasive imaging techniques like ultrasound or MRI in certain situations.

In addition to diagnostic capabilities, some angioscopes are equipped with working channels. These channels allow for the passage of small surgical instruments, enabling minimally invasive therapeutic procedures. For instance, instruments can be used to remove small blood clots, dilate narrowed vessels with balloons, or deliver medication directly to a specific site within a blood vessel. The use of angioscopes is generally performed under local anesthesia and requires specialized training for the medical professional.
