The Axxent Cervical Applicator is indicated for use with the Axxent Electronic Brachytherapy System to deliver high dose rate brachytherapy for intracavitary treatment of cancer of the uterus, cervix, endometrium and vagina.
The Axxent Cervical Applicator is a component of the Axxent Electronic Brachytherapy System (cleared under K122951) which utilizes a proprietary miniaturized X-ray source and does not require radioactive isotopes. The applicator allows the Axxent HDR X-ray source to deliver high-dose rate, low energy radiation treatment to the uterus, cervix, endometrium and vagina. The Axxent HDR X-ray source mimics the penetration and dose characteristics of Iridium-192.
The Axxent Cervical applicator is provided non-sterile and can be reused. The user must sterilize the device using steam sterilization before each use. An Applicator Clamp is a required accessory to stabilize the Cervical Applicator during radiation treatment.
The provided document is a 510(k) premarket notification for the Axxent® Cervical Applicator, primarily focused on adding MRI compatibility and MR Conditional labeling. It is not an AI/ML device, and therefore, many of the requested criteria related to AI/ML device performance and studies are not applicable.
However, I can extract information related to the acceptance criteria and the study performed for the MRI compatibility of the device, as that is the specific new claim being sought.
Here's the information regarding the MRI compatibility study:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Test Standard) | Reported Device Performance |
|---|---|
| Magnetically induced displacement force (ASTM F2052) | Results indicated the device meets the criteria for MR Conditional labeling. |
| Magnetically induced torque (ASTM F2213 as a guide) | Results indicated the device meets the criteria for MR Conditional labeling. |
| MR image artifact (ASTM F2119) | Results indicated the device meets the criteria for MR Conditional labeling. |
| Radiofrequency induced heating (ASTM F2182) | Results indicated the device meets the criteria for MR Conditional labeling. |
Note: The document states that the results of the testing "indicated that, in accordance with the guidance of relevant ASTM standards, Xoft's Cervical Applicator should be labeled MR Conditional." This implies that the device successfully met the established thresholds and requirements outlined in each ASTM standard for magnetic displacement, torque, artifact, and heating, thereby qualifying for MR Conditional labeling. Specific numerical thresholds or measured values are not provided in this summary.
2. Sample sized used for the test set and the data provenance
- Sample size: "Test samples were provided in their final manufactured condition." The exact number of samples tested is not specified, but it implies a sufficient number of devices were used for each test to achieve reliable results as per the ASTM standards.
- Data provenance: Not explicitly stated, but given it's a submission to the FDA by a US-based company, the testing was likely conducted in a controlled laboratory environment, presumably in the US. It is a prospective study as tests were conducted specifically for this submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- This question is not applicable as this is a device compatibility test, not an AI/ML diagnostic or prognostic study requiring expert ground truth for interpretation of medical images or patient outcomes. The "ground truth" here is adherence to engineering standards for MRI safety.
4. Adjudication method for the test set
- Not applicable. This involves objective physical measurements and adherence to ASTM standards, not subjective interpretation requiring adjudication among experts.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This is not an AI/ML device and no MRMC study was conducted.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is not an AI/ML device.
7. The type of ground truth used
- The "ground truth" in this context is established by the ASTM consensus standards (ASTM F2052, ASTM F2213, ASTM F2119, ASTM F2182) for evaluating MRI compatibility. Performance is judged against the objective physical criteria and thresholds defined within these standards.
8. The sample size for the training set
- Not applicable. This is not an AI/ML device; there is no training set.
9. How the ground truth for the training set was established
- Not applicable. This is not an AI/ML device; there is no training set.

Dear Mr. DeLucia:
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. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

Summary of Technological Characteristics
The technological characteristics of the Axxent Cervical Applicator have not changed since its clearance under K123442. In this pre-market clearance submission, iCAD Inc. is seeking clearance for adding MRI compatibility and MR Conditional labeling to the Instructions for Use. The Axxent Cervical Applicator is substantially equivalent to the predicate device, Mick Radio-Nuclear Instruments, Inc. Modified Henschke HDR Cervix Applicator, in terms of MR compatibility.
General Safety and Effectiveness Concerns
The device labeling contains instructions for use and any necessary cautions and warnings to provide for safe and effective use of this device. Risk management is ensured via a risk analysis which is used to identify potential hazards. Any potential hazards are controlled through development, verification and validation testing.
Assessment of Non-Clinical Performance Data
A study report was included in this submission which evaluated the Axxent Cervical Applicator for MRI compatibility in 1.5 T and 3 T clinical scanners. Test samples were provided in their final manufactured condition and were evaluated for the following:
-
- Magnetically induced displacement force (ASTM F2052)
-
- Magnetically induced torque (ASTM F2213 as a guide)
-
- MR image artifact (ASTM F2119)
-
- Radiofrequency induced heating (ASTM F2182)
The results of the testing indicated that, in accordance with the guidance of relevant ASTM standards, Xoft's Cervical Applicator should be labeled MR Conditional.
Conclusion
This traditional 510(k) for the Axxent® Cervical Applicator contains adequate information and data to determine substantial equivalence to the predicate device.
