The tantalum marker band, also called tantalum imaging ring, enables the catheter for minimally invasive cardiovascular treatment to display the specific position of the catheter during interventional treatment, which is convenient for doctors to perform interventional operations and improve the accuracy of the operation. Tantalum is widely used in medical devices due to its high density, X-ray impermeability, good biocompatibility, and physical and chemical properties. Moreover, its low price enables it to completely replace platinium-iridium alloys.
