The Vibrance Kegel Device (VKD) is intended for the strengthening of the pelvic floor muscles, which has been found to help women with urinary incontinence.

Device Description

The Vibrance Kegel Device (VKD700) is an intra-vaginal exercise device intended to strengthen the pelvic floor musculature by offering resistance to an individual's voluntary contractions of these muscles. The Vibrance Kegel Device incorporates an active vibration biofeedback mechanism for the identification of the pelvic floor muscles, and the sheaths provide graduated resistance levels for the progressive strengthening of the pelvic floor muscle.

The therapeutic effect is from the user using the device to exercise the pelvic floor muscles in accordance with the exercise program included in the instructions. The device provides biofeedback information that allows the user to verify the use of the correct muscles in the exercise routine and thus the effectiveness of the exercises undertaken. The device also includes a resistive component to the training program to strengthen the pelvic floor muscle via physiologic principles. The biofeedback mechanism works by directly sensing the force applied by the pelvic floor muscle.

The device consists of a Main Body and three Resistance Sheaths with varying degrees of stiffness. It has a PCB assembly, and is battery powered by two independent 3V CR 1220 Lithium Batteries operating on two independent, enclosed electronic circuits for the vibration biofeedback loop and the other for audio guided training. The maximum diameter of the Vibrance Kegel Device shaft is 2.4 cm. The maximum inserted length of the shaft is 6 cm.

AI/ML Overview

The provided text is a 510(k) summary for the Vibrance Kegel Device (VKD), which is a medical device and not an AI/ML powered device. As such, it does not include information on acceptance criteria and study designs that would be typical for an AI-powered device. Therefore, I cannot provide the requested information in the format requested.

The document discusses the substantial equivalence of the VKD to a predicate device, focusing on:

Intended Use: Strengthening pelvic floor muscles to help with urinary incontinence.
Technological Characteristics: Resistive vaginal exerciser with vibration biofeedback.
Non-Clinical Performance Data: Mechanical testing, biocompatibility (ISO 10993-1, -5, -10, -12), electromagnetic compatibility (IEC 60601-1, -1-11), and risk analysis (ISO 14971).
Clinical Performance Data: No clinical testing was deemed necessary as the device's indications for use and safety/efficacy are considered equivalent to the predicate device, which has a long market history.

Essentially, the acceptance criteria for this device are its ability to function safely and effectively as a perineometer for strengthening pelvic floor muscles, demonstrated through non-clinical testing and comparison to a legally marketed predicate device.

To directly answer your numbered points based on the provided text, while acknowledging the lack of direct AI/ML relevance:

A table of acceptance criteria and the reported device performance:
Since this is not an AI/ML device, the "acceptance criteria" are not quantitative performance metrics like sensitivity/specificity but rather successful completion of various engineering and biocompatibility tests to demonstrate safety and functional equivalence to the predicate.

Not applicable. This is not an AI-assisted diagnostic or workflow tool, and no human readers are involved in interpreting output for this device.
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical medical device, not an algorithm.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
As mentioned above, "ground truth" in the AI/ML sense is not applicable. The device's "truth" is its compliance with established engineering and biocompatibility standards (e.g., ISO, IEC), and its functional equivalence to a legally marketed predicate device.
The sample size for the training set:
Not applicable. This device does not use a "training set" as it is not an AI/ML algorithm.
How the ground truth for the training set was established:
Not applicable, as there is no training set for an AI/ML algorithm.

9. Non-Clinical Performance Data

The following testing has been performed to support substantial equivalence:

Mechanical Testing – Compression testing was conducted on the Vibrance Kegel Device to measure the forces required to vibrate the sensor for each of the three levels of resistance sheath. A pull off test was also conducted to evaluate how much force is needed for the sheath to be removed from the main body when the device is in use, but is adequate for removal of a sheath after use. A correlation measurement test was then conducted to evaluate the test results of the compression test. The mechanical testing concluded that the different components of the device would function properly and safely when exposed to loads and configurations representative of normal use.

Biocompatibility - The biological safety of the Vibrance Kegel Device was evaluated in accordance with ISO 10993-1:2009 and guidance document entitled Blue Book Memo, G95-1, Use of International Standard ISO-10993, and Biological Evaluation of Medical Devices: Part 1: Evaluation and Testing. Under these, for the stated indications for use, each component of the device's biological safety was evaluated for in vitro cytotoxicity, skin sensitization, and vaginal irritation.

In Vitro Cytotoxicity test was performed according to ISO 10993-12 and ISO 10993-5, with the results suggesting that the test articles did not induce a cytotoxic effect.
Skin Sensitization (Maximization Test) was performed according to ISO 10993-10, with the results suggesting that the device extracts did not produce skin sensitization in guinea pigs.
Irritation (Vaginal Irritation Study) was performed on New Zealand White Rabbits according to ISO 10993-10, with the results showing that there were no significant clinical signs and gross findings in either the control or test group, and there were no mortalities.

Electromagnetic Compatibility - The Vibrance Kegel Device complies with the applicable voluntary standards which include IEC 60601-1 and IEC 60601-1-11. The Vibrance Kegel Device complies with these voluntary standards including IEC 60601-1-11 for Electrical Safety and for systems used in the home healthcare environment.

Risk Analysis - Formal Risk Assessment of the Vibrance Kegel Device was performed in accordance with ISO 14971. With respect to perceivable conditions in which the device would be subjected to a worst-case environmental or human error scenario, Bioinfinity believes the outcomes of these risks are considered acceptable within the context of ISO 14971, and that all potential risks have been mitigated to the lowest form.
