Injectors and Tantalum Markers

RSA Biomedical is the world’s foremost provider of Tantalum Markers / Tantalum Beads, and Tantalum Marker Injectors. Our RSA® Injector™ and RSA® Tantalum Markers™ are well proven, are used in hundreds of RSA® studies, and meet the highest standards of quality in medical research.

RSA® Injector™

The RSA® Injector™ is designed to help surgeons easily insert spherical RSA® Tantalum Markers™ in the skeleton. It is a well-balanced and robust tool, developed in collaboration with medical experts having extensive experience in RadioStereometric Analysis (RSA®).

  • Easy to use.
  • Robust, modular design.
  • Easy to clean and sterilize.
  • For percutaneous insertion of Tantalum Markers.

The RSA® Injector™ is ergonomically designed to help surgeons insert markers accurately and efficiently. The RSA® Injector™ is easy to dissemble, sterilize, assemble, and load. It uses a spring-loaded punch to force markers into the skeleton.

The RSA® Injector™ is available in two sizes, for 0.8 mm and 1.0 mm RSA® Tantalum Markers™.

RSA® Tantalum Markers™

Skeletal and prosthetic device markers used in the RSA® system are made of biocompatible spherical tantalum, a material that is well tolerated by the body and readily observed as a distinct point in the radiograph.

RSA Biomedical offers 3 sizes of RSA® Tantalum Markers™, in diameters of 0.5, 0.8, and 1.0 mm.

RSA® Tantalum Markers™ are also known as RSA® Tantalum Beads.
