Intended Use

The Intimina KegelSmart and Intimina KegelSmart Pearl are intended for independent use by women at home to strengthen pelvic floor muscles to treat stress and/or urge urinary incontinence.

Device Description

The Intimina KegelSmart and KegelSmart Pearl are pelvic floor muscle exercise devices that provides biofeedback and exercise guidance. Each time the device is used it registers the user's pelvic floor muscle contraction strength and automatically sets a strength level, from 1 to 5, for the following session. Each level has a corresponding exercise routine that is communicated to the user with gentle vibrations.

AI/ML Overview

The provided text is a 510(k) Summary for the Intimina KegelSmart and KegelSmart Pearl devices. It describes the device, its intended use, and argues for its substantial equivalence to a predicate device. However, it does not contain a specific study proving the device meets acceptance criteria in terms of clinical performance metrics like sensitivity, specificity, accuracy, or effect size for improvement in human readers with AI assistance.

Instead, the document focuses on:

  • Substantial Equivalence: Comparing the technological characteristics of the new device to a predicate device (The Reflex Treatment System).
  • Safety and Performance Standards: Stating conformity with biological evaluation (ISO 10993) and electrical safety (IEC 60601) standards, and software guidance.
  • Functional Performance Testing: A brief mention that functional performance testing was provided to demonstrate the device operates per its Instructions for Use, without detailing the results or acceptance criteria for this testing.
  • Literature Review: A general statement about evidence in published literature regarding the effectiveness of pelvic floor muscle training for urinary incontinence.

Therefore, I cannot populate the requested table (1) or address points 2-7, 9 in detail based solely on the provided text, as this information is not present. The document describes a regulatory submission for substantial equivalence based on technological similarity and compliance with general safety/performance standards, not a clinical study demonstrating specific performance metrics against defined acceptance criteria for the new device.

Here's what can be extracted and what is missing:

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not mentioned.
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, as this is not an AI-assisted diagnostic device, and no MRMC study or AI component in that context is discussed.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable, as this is not an algorithm-only device in the diagnostic sense. The device itself (hardware and embedded software) provides guidance.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not mentioned for any specific study of the device. The "ground truth" for the device's efficacy is largely derived from the existing medical literature on pelvic floor muscle training.
8. The sample size for the training set: Not applicable; this device is not a machine learning model that requires a training set in the typical sense for image analysis or diagnostics. Its "training" happens internally as it adapts to the user's strength.
9. How the ground truth for the training set was established: Not applicable for the reasons mentioned in point 8.

Comparison of Technological Characteristics with the Predicate Device

{5}------------------------------------------------

Summary of Differences in Technological Characteristics

The subject and predicate device do not have the same technological characteristics. The different technological characteristics between the subject and predicate device are as follows:

  • Measurement of contraction strength The subject devices use an electric ● resistance strain gauge, and the predicate device uses a MEMS air pressure sensor.
  • Levels of resistance The subject devices have five levels of resistance, and the . predicate device has three.
  • Feedback mechanism The subject devices use vibrations to prompt the user to . contract their pelvic floor muscles, whereas the predicate device uses visual cues on an LCD screen.
  • . Exercise routines - The subject and predicate devices utilize different exercise routines.

The different technological characteristics between the subject and predicate device do not raise different questions of safety and effectiveness, as pelvic floor muscle exercise devices often vary with respect to their measurement of contraction strength, levels of resistance, feedback mechanism, and exercise routines.

Summary of Performance Data of KegelSmart and KegelSmart Pearl

There is evidence in the published literature that regular pelvic floor muscle training results in a significant increase in pelvic floor muscle strength, is an effective treatment for stress or mixed urinary incontinence.

Intimina KegelSmart and KegelSmart Pearl (model 1 and 2) are in conformity with the applicable requirements of the following documents:

Ref. No.Title
ISO 10993-5Biological evaluation of medical devices Part 5 Tests in vitro cytotoxicity
ISO 10993-10Biological evaluation of medical devices. Part 10: Tests for irritation andskin sensitization

IEC 60601-1-2:2007Medical electrical equipment -Part 1-2:General requirements for safety-Collateral standard: Electromagnetic compatibility -Requirements andtests

The software for the Intimina KegelSmart Pearl is in line with the recommendations outlined in the FDA guidance document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" issued in final on May 11, 2005.

Functional performance testing was provided on the Intimina KegelSmart and KegelSmart Pearl demonstrating that it operates per its Instructions for Use.

Conclusion

The conclusions drawn from the nonclinical tests demonstrate that the Intimina KegelSmart and Intimina KegelSmart Pearl are substantially equivalent to the proposed predicate device.

§ 884.1425 Perineometer.

(a)
Identification. A perineometer is a device consisting of a fluid-filled sack for intravaginal use that is attached to an external manometer. The devices measure the strength of the perineal muscles by offering resistence to a patient's voluntary contractions of these muscles and is used to diagnose and to correct, through exercise, uninary incontinence or sexual dysfunction.(b)
Classification. Class II (performance standards).
