0.5mm Tantalum Marker Beads

X-medics offers tantalum RSA markers for insertion into medical device materials. Unfortunately we do not sell finished medical devices nor sell products fully prepared for end-user surgery. In case X-medics’ products are used for clinical trials it will have to be performed under responsibility of a principal investigator.

Unique Biocompatibility

Spherical tantalum markers have been used for more than 30 years for roentgen (x-ray) stereophotogrammetric or radio stereometric analysis without any severe events reported. X-medics’ tantalum RSA markers have today been used in clinical trials on several thousand patients. X-medics markers are made from surgical grade tantalum. Tantalum is biocompatible, well tolerated by the body, and readily observed as a distinct point in the radiograph. As tantalum markers are radio-opaque and requires only a low x-ray dose for examination.
