Intended Use
Pelvic Floor Muscle Stimulator (Model name: MagBelle AF180) is intended to provide entirely non-invasive electromagnetic stimulation of pelvic floor musculature for the purpose of rehabilitation of weak pelvic muscles and restoration of neuromuscular control for the treatment of male and female urinary incontinence.
Device Description
The Pelvic Floor Muscle Stimulator (model: MagBelle AF180) is a non-invasive therapeutic device which produces electromagnetic field that interacts with the tissues in the pelvic region of the human body. The electromagnetic field delivered in the muscular tissue area triggers the muscle stimulation. MagBelle AF180 consists of the main unit and the chair applicator. The MagBelle AF180 is equipped with a color touch screen that facilitates the use of the device. The on-screen information guides the user step-by-step through the entire therapy procedure. The therapeutic parameters can also be set using the touch screen, buttons and knob on the device. During the device keeps information about the applied therapy type, remaining therapy time and main therapy parameters on the screen. The subject device should only be used under the continued supervision or licensed practitioner. The device supports 3 different function modes: Magnetic stimulation function, Kegel biofeedback training function and Triggering magnetic stimulation function of Magnetic stimulation function and Kegel biofeedback training function).
More Information

No
The document does not mention AI, ML, or related terms, and the description of the device's functionality and testing does not suggest the use of such technologies. The "calibration" mentioned in the performance studies appears to be a standard device calibration process, not an AI/ML training process.

Yes
The "Device Description" explicitly states that the Pelvic Floor Muscle Stimulator (MagBelle AF180) is a "non-invasive therapeutic device." Additionally, its "Intended Use / Indications for Use" describes its purpose as "rehabilitation of weak pelvic muscles and restoration of neuromuscular control for the treatment of male and female urinary incontinence," indicating a therapeutic function.

Yes

The device has a "Kegel biofeedback training function" which measures pelvic floor muscle strength. This measurement is used to identify normal versus weak pelvic floor muscle strength, indicating a diagnostic capability.

No

The device description explicitly states it consists of a "main unit and the chair applicator" and produces an "electromagnetic field," indicating it is a hardware device with software control, not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Pelvic Floor Muscle Stimulator (MagBelle AF180) is a therapeutic device that uses electromagnetic stimulation to directly treat pelvic floor muscles. It does not analyze samples taken from the body.
  • Intended Use: The intended use is for the rehabilitation and restoration of neuromuscular control of pelvic floor muscles for the treatment of urinary incontinence. This is a therapeutic application, not a diagnostic one.
  • Device Description: The description focuses on the physical components and how it delivers electromagnetic stimulation to the body.
  • Performance Studies: The performance studies described involve measuring and comparing muscle strength, which is a physiological measurement, not an in vitro test.

Therefore, the MagBelle AF180 falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.

Description of the test set, sample size, data source, and annotation protocol

To verify the Kegel Biofeedback functionality, the sponsor tested the subject device in 100 urinary incontinence patients (male and female, age range: 22-70) in a hospital set-up. All the patients' pelvic floor muscles strength was tested manually by a clinician by using modified Oxford Grading Scale. Then, the patients' pelvic floor muscle strength was measured by using the subject device. Thus, the Kegel biofeedback mode of the subject device was calibrated to identify the values of the biofeedback signal corresponding to normal and weak pelvic floor muscle strength. The pelvic floor muscle strength measured by the subject device was also compared to the pelvic floor muscle strength measured by a reference device, K201014 (MyOnyx System).

As evidenced by the above table, both the subject and the predicate devices have similar intended use, but the subject and predicate devices have different technological characteristics. However, performance testing was conducted on the subject device, and it was established that the differences in technological characteristics between the subject and the predicate does not raise different questions of safety or effectiveness.

7. Non-Clinical Testing

Below is a list of the tests that were performed and successfully completed for the subject device per the below guidance and standards:

  • Biocompatibility testing according to ISO 10993-1:2018 Biological evaluation of medical O devices - Part 1: Evaluation and testing within a risk management process and FDA Guidance "Use of International Standard ISO 10993-1" (2016).
  • Electrical Safety testing according to IEC 60601-1: 2020 Medical electrical equipment - O Basic safety and essential performance
  • Electromagnetic Compatibility testing according to IEC 60601-1-2: 2020 General O requirements for basic safety and essential performance -- Collateral Standard: Electromagnetic disturbances -- Requirements and tests
  • IEC 60601-2-10:2016 Particular requirements for the basic safety and essential O performance of nerve and muscle stimulators
  • o Software Verification and Validation Testing according to FDA's Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices"

Additionally, performance bench data was submitted for device performance and durability of the subject device. This data included:

6

  • o Service life verification test
  • o Stimulation Coil Surface Temperature Rise Test
  • 0 Maximum Magnetic Field Strength Test
  • o Cybersecurity testing

All pre-determined acceptance criteria were met.

Clinical Data Summary 8.

To verify the Kegel Biofeedback functionality, the sponsor tested the subject device in 100 urinary incontinence patients (male and female, age range: 22-70) in a hospital set-up. All the patients' pelvic floor muscles strength was tested manually by a clinician by using modified Oxford Grading Scale. Then, the patients' pelvic floor muscle strength was measured by using the subject device. Thus, the Kegel biofeedback mode of the subject device was calibrated to identify the values of the biofeedback signal corresponding to normal and weak pelvic floor muscle strength. The pelvic floor muscle strength measured by the subject device was also compared to the pelvic floor muscle strength measured by a reference device, K201014 (MyOnyx System). Pelvic floor muscle conditions evaluated by both the subject and the reference devices were found to be comparable to each other.

9. Conclusions

Based on the information presented in this submission, it can be concluded that the subject device is substantially equivalent to the predicate.
