"This designation underscores our leadership in adopting evidence-based innovations that elevate patient care," said Dr. Dominique Higgins, neurosurgeon at UNC Health. "GammaTile marks an important step forward in the evolution of brain tumor care."
GammaTile is an innovative form of radiation therapy placed at the time of tumor removal surgery, delivering immediate, targeted radiation to the tumor site when cancer cells are at their lowest levels. Unlike conventional approaches, which often require a delay between surgery and radiation therapy to allow for wound healing, GammaTile eliminates this treatment gap. By delivering immediate, localized radiation directly at the tumor site, it is designed to maximize the treatment's effectiveness against remaining cancer cells and reduce the risk of regrowth.¹

About GT Medical Technologies, Inc.
GT Medical Technologies was founded by a dedicated team of brain tumor specialists to address unmet needs in brain tumor treatment. The company is committed to improving the lives of patients with brain tumors through innovative solutions that elevate the standard of care.

About GammaTile
GammaTile is an FDA-cleared, bioabsorbable collagen implant embedded with radiation seeds, designed for patients with operable brain tumors. By delivering radiation directly from within—placed into the surgical cavity at the time of tumor removal—GammaTile provides immediate, localized treatment. This approach targets remaining cancer cells when they are at their lowest levels to help prevent regrowth, while minimizing radiation exposure to healthy brain tissue.

Since its full market launch in the United States in March 2020, GammaTile has been adopted by more than 100 leading centers, underscoring its growing acceptance in both academic and community healthcare settings.
