Intended Use

The BinkieRT is intended to be used for repeat positioning and immobilization of a patient's tongue and jaw while undergoing or receiving a course of external beam radiation therapy for treatment of cancer and other diseases. It is intended to be used by or under the direction of a licensed physician. BinkieRT is meant for use with 6 MV photon beams only.

Device Story

BinkieRT is a patient-specific oral fixation device used during head and neck radiation therapy. It consists of a jaw positioner (maxilla and mandibula supports) and a tongue positioner (head and paddle) connected by a column rotation guide. The device is mounted in the patient's oral cavity to fix the temporomandibular joint and displace the tongue, minimizing normal tissue exposure to radiation. It is used in clinical/hospital settings by licensed physicians. The device provides repeat positioning and immobilization, shielding against backscatter radiation. It is constructed from molded plastic and moldable EVA thermoplastic. The device benefits patients by ensuring accurate dose delivery to the target area while protecting surrounding healthy tissue.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including biocompatibility (ISO 10993-1, -5, -10), X-ray backscatter shielding effectiveness (Dose Enhancement Ratio < 1.0), and EVA dental impression depth stability over 30 fractions (67.5 Gy total dose). Packaging and cleaning process validations were also performed.

Technological Characteristics

Patient-specific oral fixation device. Materials: Molded plastic and moldable EVA (ethylene vinyl acetate) thermoplastic. Components: Jaw positioner, tongue positioner, column rotation guide. Features: Dual bite trays, open jaw positioning, tongue displacement, backscatter radiation shielding. MRI safe. Non-powered, mechanical device.

Indications for Use

Indicated for patients undergoing external beam radiation therapy for cancer or other diseases requiring repeat positioning and immobilization of the tongue and jaw. Intended for use by or under the direction of a licensed physician. Compatible with 6 MV photon beams only.

# [Table 1. Comparison of Proposed Device to Predicate Device]

{8}------------------------------------------------

The table also provides rationale for a little difference in support of substantial equivalence to the Predicate devices

# [Table 2. Little difference with Predicate Device]

#### Justification to Support Substantial Equivalence

There are no significant differences between BinkieRT and the predicate devices that would adversely affect the use of the product. It is substantially equivalent to predicate devices in indications for use and technology characteristics.

{9}------------------------------------------------

### Non-Clinical Test summary

The BinkieRT comply with voluntary standards for electromagnetic compatibility, use in the home healthcare environment and usability. The following data were provided in support of the substantial equivalence determination:

#### 1) Biocompatibility

Bio-compatibility test is performed according to below:

- FDA Guidance document Use of International Standard ISO 10993-1, `Biological evaluation of ● medical devices- Part 1: Evaluation and testing within a risk management process
- ISO 10993-1 Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process
- ISO 10993-5 Biological evaluation of medical devices — Part 5: Tests for in vitro cytotoxicity
- ISO 10993-10 Biological evaluation of medical devices — Part 10: Tests for skin sensitization

#### 2) Bench Testing

- X-ray backscatter shielding performance .
Bench tests were conducted to verify the shielding capabilities of the Binkie RT aqainst secondary lowenergy backscatter radiation emitted by metal piling bridgework. Subjects were exposed to a 6 MV high energy photon beam and the backscatter radiation dose was radiation dose was assessed by measuring the exposure density of the industry standard Gafchromic EBT3 film placed adjacent to the subject. The Dose Enhancement Ratio was defined as the backscattered radiation dose produced by the subject divided by a "baseline" dose (backscattered radiation produced without the subject in the photon beam). Shielding effectiveness was indicated by the Dose Enhancement Ratio. Values greater values greater than 1 indicate an increased dose of backscatter radiation to the patient and a poor shielding effect, while a ratio of 1 indicates complete shielding with no dose of backscatter radiation delivered to the patient.

The Dose Enhancement Ratio of the assembled BinkieRT is just below 1.0, indicating near perfect shielding. Shows the nearly complete shielding effectiveness of the Binkie RT device in shielding backscattered radiation.

- EVA dental impression depth comparation test
Bench testing was performed to compare the depth of the EVA impression to verify that the depth of the dental arch impression was not significantly affected by bite time. using a force gauge (i.e., occlusal force qauqe) and anthropomorphic jaws, a force of ~800N was applied to the EVA once before treatment and repeated after each 2.25 Gy fraction of a total 67.5 Gy dose to the BinkieRT (i.e., 30 fractions). The force was selected as the reported maximum human bite force using a soft bite surface. Impression depth was measured with calipers for every 10 fractions and analyzed over time to detect changes in the structural integrity of the BinkieRT over the course of treatment. An effect of bite time was evaluated by measuring the deviations of impression depth with fractions compared to the initial impression depth. After the 67.5 Gy was completed, the final impression depth was compared to the previous 35 fractions.

{10}------------------------------------------------

The measured impression depth must be within the standard deviation of the initial impression depth measurements. The impression depth comparison test showed that the depth was not significantly affected by the time frame, and the test performance was similar to that of the predicate. The BinkieRT produces similar impression depths when comparing its current timeframe to the longer timeframe indicated in the Predicate device's Instructions for Use.

The non-clinical performance test results provide evidence that the BinkieRT is safe and effective when used as intended.

#### 3) Validation

- . Packaging process validation
Through several tests conducted for validation of the packaging process, optimized packaging process parameters among various packaging process conditions were identified.

The nylon packaging, which was packaged through the vacuum packaging machine, was stably packaged under the conditions of 'vacuum step 10, cooling step 10, cooling step 35', and the adhesive strength of the packaging also showed good results.

It has been verified through various tests that the wrapping paper of "BinkieRT" thermally bonded

through the validated packaging process can maintain a consistent and has the ability to protect the produet from contaminants

#### ● Cleaning process validation

The cleaning process validation was performed on the "Oral_001 (O-TYPE)", which is a worst case sample, using the cleaner that has completed installation and operation qualification (IQ / OQ).

'Asa verification method for verifying the effectiveness of the cleaning process, it met the test criteria in the physicochemical test (TOC, pH, Electrical conductivity test) performed after the final cleaning, Also, cleaning agent residue test (HPLC), residue evaporation, microorganism test (Bioburden test) and dry Validation test were suitable for the acceptable criteria,

Based on the validation results, we can conics that cleaning process is validated and itis effective to cleaning the `BinkieRT"

#### Clinical Test Summary

Clinical testing was not required to demonstrate the substantial equivalence of the BinkieRT to its predicate devices.

#### 8. Conclusion [21 CFR 807.92(b)(3)]

The BinkieRT have similar intended use and technical characteristics to the predicate device.

Based on that information, we conclude that the differences between the proposed device and predicate device do not introduce a new intended use and do not raise new issues of safety and effectiveness.
