Overview
AI-generated summary, 19 Sep 2026
Intraoperative Radiation Therapy Devices are medical systems designed to deliver high-energy charged-particle radiation, such as electrons or protons, directly during surgery. These systems accelerate particles to precise energies for targeted tumor treatment, integrating components like signal analysis, treatment planning software, and patient positioning supports. They are classified under charged-particle radiation therapy systems and are intended for use in radiology settings.
These devices are supplied as complex, multi-component systems requiring specialized training for operation. They are not single-use but are designed for repeated use in controlled clinical environments, adhering to strict regulatory standards. The systems are not inherently MRI-compatible and are regulated under FDA 510(k) clearance (K891261) with a classification as Class II devices. No specific sterility or storage conditions are noted beyond standard medical device handling protocols.

Questions
AI-generated answers, 19 Sep 2026
What is the primary purpose of these intraoperative radiation therapy devices, and where are they typically used in a clinical setting?
These devices are designed to deliver high-energy charged particles (like electrons or protons) directly to tumors during surgery, allowing precise radiation treatment while the patient is still under anesthesia. They integrate advanced components such as treatment planning software and patient positioning supports, making them ideal for radiology departments where complex, targeted tumor therapies are performed.
Are these devices single-use or reusable, and what maintenance or handling considerations should be kept in mind?
These devices are not single-use and are built for repeated use in controlled clinical environments. Since they are complex systems, they require specialized training for operation and maintenance. While no specific sterility or storage conditions are noted beyond standard medical device protocols, proper handling and adherence to regulatory standards are essential to ensure safe and effective performance.
How are these devices regulated in the U.S., and what does the FDA classification mean for their use?
These devices are regulated under the FDA’s 510(k) clearance process and are classified as Class II medical devices. The clearance (K891261) indicates they are deemed substantially equivalent to a predicate device, meaning they meet FDA standards for safety and effectiveness. This classification ensures they undergo rigorous review by the Radiology Advisory Committee before approval, ensuring their use in intraoperative radiation therapy is well-documented and compliant with regulatory requirements.
Can these devices be used in conjunction with MRI equipment, or are there any compatibility concerns?
The device data explicitly states these systems are not inherently MRI-compatible, meaning they should not be used in environments where MRI is performed or where magnetic fields are present. Clinicians should verify compatibility with their specific MRI systems before integrating these devices into a multi-modal treatment plan.
What types of facilities or departments would typically house or operate these devices, and why?
These devices are intended for use in radiology departments within hospitals or specialized cancer centers. Their integration of radiation therapy with surgical procedures requires a setting equipped to handle high-energy particle delivery, advanced imaging, and precise patient positioning—all of which align with the capabilities of radiology units. The advisory committee classification (Radiology) further confirms their intended use in this clinical specialty.
