Niobium Marker Bands are marking rings made of Niobium that are commonly used in the medical device field. These marker rings are usually applied to specific locations on medical devices such as catheters or implants to provide visual marking. Due to Niobium's biocompatibility and X-ray transparency, Niobium Marker Bands have become a common choice in the medical industry, especially in radiological and interventional procedures. They help doctors and healthcare professionals pinpoint and track specific areas to ensure accurate diagnosis and treatment. Marker bands are made by cutting Niobium small tubing or Niobium capillary tubing which can be used as radiopaque markers during angioplasty and other minimally-invasive catheter procedures. Typically, Niobium seamless tubing may be cut into Niobium cut tubing used as radiopaque marker bands and other application, Niobium marker bands are used as medical device components where radiopacity is required. e.g. Niobium capillary or Niobium cut tubing ASTM F560 (medical grade) was cut into the miniature Niobium markers(radiopaque marker), which is the suture radiopaque marker placement, Niobium myocardial markers (inner diameter 0.8 mm, outer diameter 1.3 mm, length 1.5 to 3.0 mm) were inserted beneath the left ventricular (LV) epicardial surface along 4 equally spaced longitudinal meridians for LV volume determination.
The implantation of Niobium as a radiopaque marker into the submucosal layer of the GI tract in a porcine model is technically feasible and safe. Long-lasting fluoroscopically visible tantalum markings could facilitate subsequent surgical and radiation therapy.
