Intended Use

The OARtrac® System is specifically indicated for male prostate cancer treatment to measure photon beam therapy as an adjunct to treatment planning permitting measurement of in-vivo radiation dose received on the anterior surface of a modified Prostate Immobilization Endorectal Balloon (ERB) device to monitor and verify the surrounding organs at risk, specifically the protatic rectal interface.

Device Story

OARtrac® System provides near real-time, in-vivo, multipoint radiation-dose monitoring during prostate cancer photon beam therapy. System consists of two Plastic Scintillating Detectors (PSD) embedded on a modified Prostate Immobilization Endorectal Balloon (ERB), a Clinical Detector Unit (CDU) with a Charged Coupled Device (CCD) camera, and proprietary dose management software. ERB immobilizes prostate while positioning sensors at the rectal prostatic interface. PSDs measure light output proportional to radiation dose; fiber optic cables transmit signals to the CDU. Software processes signals to calculate dose and dose rate, displaying current and historical treatment logs. Used in clinical radiation oncology settings by physicians or trained staff. Output allows physicians to compare actual delivered dose against planned dose, facilitating real-time monitoring of organs at risk. Non-implantable design reduces risks associated with invasive dosimeters.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by non-clinical bench testing, including biocompatibility (ISO 10993-1), electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), software validation (IEC 62304), and mechanical testing (balloon leak, burst, and tensile strength).

Technological Characteristics

System uses Plastic Scintillating Detectors (PSD) with fiber optic connectivity to a Clinical Detector Unit (CDU) containing a CCD camera. ERB is polyurethane. Energy range: 1-20 MV photons. Dose range: up to 90 Gy. Accuracy: ±6% at 95% confidence interval. Software-based dose calculation. Non-sterile. Single-use.

Indications for Use

Indicated for male patients undergoing prostate cancer treatment to measure photon beam therapy dose on the anterior surface of an endorectal balloon to monitor and verify radiation dose to the prostatic rectal interface.

Regulatory Classification

Identification

Device Description The OARtrac® System provides radiation oncologists with near real- time, in-vivo, multipoint radiation-dose information obtained from two (2) Radiatrac® Plastic Scintillating Detectors (PSD) sensors located on the anterior surface of a modified clinically accepted OARtrac® prostate Endorectal Balloon (ERB) to monitor dose photon based radiation {1}------------------------------------------------ therapy for prostate cancer treatment. This information allows the physician to monitor the dose at the rectal prostatic interface, compare the actual dose relative to the planned dose, and provides graphs and dose information for both the current treatment as well as a log of dose from five previous treatments. The OARtrac® System also provides dose rate during actual treatment. The function of the OARtrac® prostate ERB is to immobilize the prostate while at the same time positioning the Radiatrac® PSD sensors so that measurement of in-vivo radiation received on the anterior surface of the balloon can be monitored to verify the radiation dose to surrounding organs at risk, specifically the protatic rectal interface. The actual verification of the dose radiation is accomplished by the other main components of the OARtrac® System, those being the Clinical Detector Unit (CDU) with its Charged Coupled Device (CCD) camera and the system's own proprietary dose management software that are further addressed in the remainder of this section. ## 7. Indication for Use Statement The OARtrac® System is specifically indicated for male prostate cancer treatment to measure photon beam therapy as an adjunct to treatment planning permitting measurement of in-vivo radiation dose received on the anterior surface of a modified Prostate Immobilization Endorectal Balloon (ERB) device to monitor and verify the surrounding organs at risk, specifically the protatic rectal interface. #### 8.

Non-Clinical Performance Data As part of demonstrating safety and effectiveness of the OARtrac® System and in showing substantial equivalence to the predicate devices that are subject to this 510(k) submission, RadiaDyne completed a number of tests. The OARtrac® System meets all the requirements for overall design, sterilization, biocompatibility, package shelf-life, electrical safety and EMC, which confirms that the output meets the design inputs and specifications for the device. The OARtrac® System passed all the testing in accordance with national and international standards shown below to support substantial equivalence of the subject device to the predicates for which substantial equivalence is being claimed. - Biocompatibility Testing per ISO 10993-1 (Parts 5, 10 and 11) . - Electrical Safety per IEC 60601-1 - � EMC per IEC 60601-1-2 - Software Verifications and Validation per IEC 62304 . - . Bioburden per ISO 11137-1 - Package Shelf-Life per ASTM F1090-07 - Device Risk Analysis per ISO 14971 - Dose Range Verification Testing - Ship Testing Calibration Testing � - . Balloon Leak Test - . Balloon Tensile Strength Test ' - . Balloon Burst Strength Test - . Balloon Stopper Resistance Test ## 10. Clinical Performance Data There was no human clinical testing required to support the OARtrac® System as the indications for use is equivalent to the predicate devices. These types of devices, including the predicate devices, have been on the market for many years with a proven safety and efficacy for the use of the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the OARtrac® System. ## 11. Statement of Substantial Equivalence {7}------------------------------------------------ By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared device, or has the same intended use and different technological characteristics, but it can be demonstrated that the new device is substantially equivalent to the predicate device, and that the new device does not raise any questions regarding its safety and effectiveness when compared to the predicate device. The OARtrac® System functions as both a radiation does verification system and as a prostate immobilizer and positioning device in one complete system, whereas the predicate devices would have to be used in combination to have the same intended use on a male subject. In addition, the OARtrac® System's ERB component is not implanted, thus reducing the risk of complications such as infection, implant migration, implant placement, and adverse reactions to implants by the patient, etc. Therefore, based on the substantial equivalence analysis described above, the OARtrac® System, as designed, developed and manufactured for RadiaDyne, is determined to be substantially equivalent to the Dose Verification System (K083035) manufactured by Sicel Technologies, and to the Prostate Immobilizer Rectal Balloon (K132194) designed, developed and manufactured for RadiaDyne. {8}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/8/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
