Boston Scientific

Summary: The Therasphere 360 Y-90 Management Platform is a medical device used for Y-90 radioembolization, primarily in the treatment of liver cancer. It is utilized by interventional radiologists and oncologists to deliver targeted radiation therapy.

FDA Clearance Information

Pathway 510K
Decision Date October 28, 2025
Product Code LLZ
Device Class Class 2
Evidence 14 studies

The Therasphere 360 Y-90 Management Platform was cleared via the FDA 510k pathway on October 28, 2025. Manufactured by Boston Scientific, it is classified as a Class 2 device under product code LLZ.

What It Is

The Therasphere 360 Y-90 Management Platform is a sophisticated device designed for the administration of Yttrium-90 (Y-90) microspheres. These microspheres are used in radioembolization procedures to deliver targeted radiation therapy directly to liver tumors. The platform facilitates precise dosimetry and delivery, enhancing the safety and efficacy of the treatment.

Clinical Applications

This device is commonly used in interventional radiology and oncology settings for the treatment of hepatocellular carcinoma and metastatic liver cancer. It is particularly beneficial for patients who are not candidates for surgical resection or systemic chemotherapy. The platform is used in hospitals and specialized cancer treatment centers, often involving a multidisciplinary team approach.

Indications for Use

The FDA-cleared indications for this device include the treatment of primary and metastatic liver tumors. It is intended for patients who require localized radiation therapy to manage tumor growth and improve quality of life.

Practical Considerations

Clinicians should consider the patient's liver function and tumor vascularity when planning treatment with the Therasphere 360. The device is compatible with standard catheterization techniques, and proper training is essential to ensure accurate delivery of the Y-90 microspheres.
