The device description focuses on pre-set programs, biofeedback-based games, and standard electrical stimulation technology. There is no mention of AI, ML, or any learning or adaptive algorithms.
Yes
The device is described as providing "electrical stimulation and neuromuscular re-education for the purpose of rehabilitation of weak pelvic floor muscles for the treatment of stress, urge and mixed urinary incontinence in women and to maintain urinary continence in women," which directly indicates a therapeutic purpose.
No
The device is intended to provide electrical stimulation for neuromuscular re-education and rehabilitation of weak pelvic floor muscles, and uses biofeedback programs to facilitate patient-initiated muscle contractions. It does not mention diagnosis of any condition.
No
The device description explicitly details hardware components such as a cabinet, touch screen LCD, battery, cables, plugs, and a vaginally inserted electrode. It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide electrical stimulation and neuromuscular re-education for the treatment of urinary incontinence and to maintain urinary continence. This is a therapeutic purpose, not a diagnostic one.
- Device Description: The device is described as providing electrical stimulation (NMES) and biofeedback. It uses a vaginally inserted electrode to stimulate muscles. This is consistent with a physical therapy or rehabilitation device, not a device that analyzes biological samples to diagnose a condition.
- Lack of IVD Characteristics: There is no mention of the device analyzing biological samples (like blood, urine, or tissue) or providing diagnostic information about a disease or condition.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition. This device's function is to directly stimulate and re-educate muscles, which is a therapeutic intervention.

Indications for Use Discussion
Table of Comparative Indications for Use (Unchanged) Section 5.0 Table 1
Predicate Device and Applicant Device Indications for Use are Identical
The device is intended to provide electrical stimulation and neuromuscular re-education for the purpose of rehabilitation of weak pelvic floor muscles for the treatment of stress, urge and mixed urinary incontinence in women and to maintain urinary continence in women.
The indications for use treat stress, urge and mixed incontinence in women and to maintain urinary continence in women are consistent with the use described under 21 CFR 876.5320 and identical to the predicate. The biofeedback programs (programs 7 to 10) enable the user to bridge muscle stimulation (as defined by 21 CFR 876.5320) with patient-initiated muscle contractions (i.e., "true exercise"). Therefore maintaining continence with pelvic floor muscle control exercise is well within the purview of 21 CFR 876.5320 and thus concordant and unchanged from the Predicate.

Device Substantial Equivalence and Safety
The device modifications in the Applicant device have been introduced to encourage and facilitate the user to transition from "muscle stimulation" to "true exercise" and do not affect the intended use of the device. The NMES programs (programs 1 to 6) provide muscle stimulation concordant with the use described under 21 CFR 876.5320. These programs are identical to the Predicate and the power density out-put of the device is identical to the Predicate. The biofeedback programs (programs 7 to 10) enable the Applicant device to bridge muscle stimulation (as defined by 21 CFR 876.5320) with patient-initiated muscle contractions (i.e., "true exercise") to achieve the same unchanged indications for use under 21 CFR 876.5320. These program comparisons are are demonstrated in Section 5.0 Table 3 below:

The bio-feedback feature (programs 7 to 10) is an accessory that supplements the performance of the parent device (i.e., the treatment of female urinary incontinence in out-put NMES programs 1 to 6) because bio-feedback adds a new way of using the device without changing the intended use of the parent device (i.e., the performance of the accessory is defined under 21 CFR 882.5050). Furthermore, since the indications for use are unchanged from the Predicate the use and risk of the Applicant device, with the accessory, may be considered reasonably consistent and unchanged from the Predicate. The Applicant device allows the user to graduate from muscle stimulation to low-impact exercise.
The Applicant and Predicate devices are programmed exactly the same way, by hardwire connection to the Circuit Board. Neither the Applicant nor the Predicate device can be programmed by remote radio frequency signals. The product firmware is written in a secure (proprietary) code.
The applicant device has a unique, high level security system that monitors and controls the incoming and outgoing electronic traffic based on predetermined security rules will not allow stimulation during the use of any gaming (Biofeedback) programs (i.e., the device will not allow a game program to be engaged during a NMES program). Conversely, a user cannot start muscle stimulation (NMES programs 1 to 6) without first exiting (full stop) the game program mode. A patent has been filed for this unique security in the Applicant device. The product firmware does not contain any games. The games are coded into the file of a micro Secure Digital (SD) card only.
The biocompatible materials, and vaginally inserted electrode in the Applicant device, Y ARLAP II, Model ECS323P are identical or substantially equivalent (See Table 2) to the predicate device: Yarlap, Model ECS 323 (K141643). Power density for both skin and vaginal electrodes was calculated in the Predicate 510(k) and are recapped here below and recounted in Section 12.0 Substantial.
The Risk Assessment prepared by an independent firm and reviewed by independent commentators, in accordance with the Quality System Regulation (including documentation of design inputs, risk analysis, design output, test procedures, verification and validation procedures, and documentation of formal design reviews) demonstrate that the product modifications are as safe, and effective, and that the Applicant device performs as well as the Predicate device.
Special 510(K) Notification of a Modified Device: Yarlap II, Model ECS323P ProCode: KPI & HCC
4 See YARLAP II KPI Special 510(K) Application Section 16.9 Software Non Provisional US Patent. The applicant device is unique in that the applicant device security system that monitors and controls the incoming and outgoing traffic based on predetermined security rules prohibits in any way the biofeedback programming to change TENS or NMES (mA) out-put, when in the TENS or NMES mode of operation, or to change/deliver an out-put when the device is operating in the biofeedback mode. There is no TENS mode of operation in any Yarlap device. The Applicant believes that an OTC device for the female pelvic floor should not have TENS capabilities.
