The summary describes a system for measuring radiation dose using sensors and comparing it to a planned dose. There is no mention of AI or ML in the device description, intended use, or performance studies. The system provides data for a trained professional to interpret, rather than using AI/ML for analysis or decision-making.
No
The device measures radiation dose to validate treatment, but it does not directly treat or diagnose a disease or condition. Its purpose is to provide data to adjust a patient's treatment plan, not to provide therapy itself.
No
The device measures radiation dose received by the patient and compares it to the planned dose; it does not diagnose a medical condition or disease.
No
The device description explicitly mentions "pre-calibrated PSD sensors" and the intended use describes adhering these sensors to the skin or inserting them into the rectum. These are hardware components, not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The OARtrac® System measures radiation dose received by the patient's body during cancer treatment. It does not analyze samples taken from the body.
- Intended Use: The intended use is to measure and validate radiation dose in vivo (within the living body) as an adjunct to treatment planning.
- Device Description: The description reinforces that it provides dose data obtained during the treatment to compare with the planned dose.
The device is used to monitor and validate a physical treatment (radiation therapy) applied to the patient's body, not to diagnose or monitor a condition by analyzing biological samples.
N/A
Intended Use / Indications for Use
The OARtrac® System with patient specific, reusable up to five times, pre-calibrated PSD sensors are intended for use during cancer treatments to measure photon and electron radiation therapy as an adjunct to treatment planning permitting measurement and validation of radiation dose received by the patient to the targeted area of their body. The system is indicated for use with electron energy when adhered to the skin with or without a bolus, and for photon energy when adhered to the skin with a minimum 3mm bolus or inserted into the rectum for measurements at the rectal wall during cancer treatment via a specifically designed OARtrac® endorectal balloon device.

Device Description
The OARtrac® System with patient specific, reusable up to five times, pre-calibrated PSD sensors is intended for use in photon and electron radiation therapy to monitor and validate radiation dose during External Beam Therapy and HDR Brachytherapy to the surface of the skin or the rectal wall. This dose verification information obtained during the treatment is then used to compare with the planned dose that the Radiation Oncologists expect to provide to the patient. The OARtrac® System itself does not stop the radiation treatment to the patient, or change the radiation delivery, but only provides dose data which a trained Radiation Oncologist can decipher and use to adjust a patient's treatment plan accordingly.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Performance Data: As part of demonstrating safety and effectiveness of the OARtrac® System and in showing substantial equivalence to the predicate device, RadiaDyne completed several tests. Like the predicate device, the OARtrac® System meets all the requirements for overall design, sterilization, biocompatibility, packaging, shelf-life, electrical safety and EMC, which confirms that the output meets the design inputs and specifications for the device. The proposed device was subjected to the same test protocols and standard validation studies as the predicate device, which were previously accepted by FDA under K162954. The OARtrac® System meets criteria under the same national and international test standards as the predicate device. Performance data submitted in support of the OARtrac® System demonstrate that the device is substantially equivalent to the predicate device in performance and fundamental technology and is as safe and effective as the predicate device.

Dear Ms. Allis:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

9. Non-Clinical Performance Data
As part of demonstrating safety and effectiveness of the OARtrac® System and in showing substantial equivalence to the predicate device, RadiaDyne completed several tests. Like the predicate device, the OARtrac® System meets all the
6
requirements for overall design, sterilization, biocompatibility, packaging, shelf-life, electrical safety and EMC, which confirms that the output meets the design inputs and specifications for the device. The proposed device was subjected to the same test protocols and standard validation studies as the predicate device, which were previously accepted by FDA under K162954.
The OARtrac® System meets criteria under the same national and international test standards as the predicate device. Performance data submitted in support of the OARtrac® System demonstrate that the device is substantially equivalent to the predicate device in performance and fundamental technology and is as safe and effective as the predicate device.

10. Clinical and Animal Performance Data - Not Conducted
The OARtrac System does not introduce new intended uses, modes, features, or technologies relative to the predicate device that would require evaluation through clinical or animal testing. These types of devices, including the predicate device, have been on the market for many years with proven safety and effectiveness for their intended use. The non-clinical testing detailed in this submission is sufficient to demonstrate that the OARtrac® System is as safe and effective as the predicate device in support of a substantial equivalence determination.
11. Statement of Substantial Equivalence
In conclusion, the tests conducted, as well as all verification and validation activities, demonstrate that the design specifications and technological characteristics of the OARtrac® System meet applicable requirements and standards for the safety and effectiveness of the device for its intended use. The intended use and fundamental technology are the same between the subject and predicate devices. There are some differences in the indications for use and technological characteristics between the predicate and subject devices, but those differences allow for the subject device to have additional use capabilities during electron-based radiation treatments. The testing and validation activities conducted demonstrate that any differences between the devices do not raise new or different questions of safety or effectiveness as compared to the predicate device. Therefore, the OARtrac® System is substantially equivalent to the predicate device.
