Blood vessel sizer

Blood vessel sizers are sterile surgical instruments designed to measure the physical dimensions of a blood vessel, such as its length and luminal circumference, before an invasive procedure. These measurements help clinicians select the correct size for implants or guide the safe administration of contrast media during angiography. The device is typically a long, slender, flexible rod that is inserted into the vessel to take precise anatomical readings.

This category consists of single-use devices that feature radiopaque markers along the working end to ensure visibility under X-ray imaging. Because they are sterile and intended for one-time use, they are supplied as ready-to-use disposable instruments. The distal end of these sizers is available in various shapes and sizes to accommodate different vascular anatomies.
