More Information

Not Found

No
The summary does not mention AI, ML, or any related concepts, and the device description focuses on RF energy delivery.

Yes
The device is intended for the non-invasive "treatment" of mild to moderate facial wrinkles, which implies a therapeutic purpose.

No

The device is described as being for "non-invasive treatment of mild to moderate facial wrinkles" and delivering "RF current into the skin to generate heat". This indicates a therapeutic function, not a diagnostic one.

No

The device description explicitly lists hardware components: the applicator unit, power supply, and preparation gel. This indicates it is a physical device, not software-only.

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

Here's why:

  • Intended Use: The intended use is for the non-invasive treatment of facial wrinkles. This is a therapeutic purpose, not a diagnostic one.
  • Device Description: The device delivers RF current to generate heat in the skin. This is a physical treatment mechanism, not a method for analyzing biological samples.
  • No mention of biological samples: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening. The STOP U device does not interact with or analyze such samples.

The device is clearly described as an electrosurgical device intended for aesthetic treatment.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The effect of treatment of mild to moderate facial wrinkles using the STOP U was tested in a clinical trial that was conducted to support the clearance of the prescription version of the STOP U device (K140255).
40 subjects (37 female and 3 male) were enrolled in the study. Subjects were followed for 3 months post last treatment.
Over 80% of the subjects showed at least one grade improvement in Fitzpatrick wrinkle score at three months follow-up post treatment based on objective evaluations of the baseline and three months follow-up photographs. There were no incidences of adverse effects or complications. As expected, mild to moderate erythema and mild edema were detected at the site of treatment immediately after treatment. All cases resolved without treatment within a few hours. Treatment was well tolerated with minimal to no pain in the majority of study subjects. The data reported in this study clearly indicates that the Stop U provides a safe and effective treatment for facial wrinkles.

Pollogen conducted a usability study for the STOP U device which was divided into two stages:

  1. Stage one Self-Selection Study of the STOP U Device;
  2. Stage two - Human Factors Validation of the Pollogen STOP U Device.

The Self -Selection study using the final STOP U packaging design produced a correct self-selection rate that met Pollogen's goal. The final packaging design promotes correct self-selection and adequately explains user eligibility to potential users in the real world.
61 subjects (39 female and 22 male) which had successfully identified themselves as potential device users participated in the Human Factors validation with 100% success rate. These results indicated that the design of the STOP U and its associated instructional materials facilitated safe use of the device.

Intended Use / Indications for Use

The STOP U device is intended for use in the non-invasive treatment of mild to moderate facial wrinkles for adult users who have Fitzpatrick Skin Types II-IV.

Device Description

The STOP U device delivers RF current into the skin to generate heat through electrical impedance in the dermis and subcutaneous layers. The device consists of the following components and accessories: The STOP U device (applicator unit), the STOP U Power Supply and the STOP Preparation Gel.

Technological Characteristics

The STOP U device delivers RF energy at a frequency of 1 MHz and a maximum output RMS power of 5.7 watts into the skin through its electrodes. The device generates heat through electrical impedance in the dermis and subcutaneous layers. The temperature sensor, located between the electrodes constantly monitors the skin temperature and disables RF transmission once the desired skin temperature is obtained.

Performance Data

Pollogen conducted several performance tests to demonstrate that the STOP U device complies with performance standards and that it functions as intended.

  • STOP U Electrical safety and compatibility testing was performed to validate the STOP U power control and accuracy in reference to the user's input.
  • STOP U over-heating safety testing was performed to validate the conformity with the STOPU's design requirements and specifications for its temperature sensor and profile in reference to the user's input.
  • -The STOP U software was validated as required.

In all instances, the STOP U device functioned as intended and observations were as expected.

Performance Standards

The STOP U device complies with the following performance standards:

Clinical performance data

Safety & Effectiveness

The effect of treatment of mild to moderate facial wrinkles using the STOP U was tested in a clinical trial that was conducted to support the clearance of the prescription version of the STOP U device (K140255). Since the over-the-counter (OTC) version of the STOP U device is identical to the prescription version, this data is also applicable to support the safety and effectiveness of the OTC device.

Altogether, 40 subjects (37 female and 3 male) were enrolled in the study. Subjects were treated for improvement of facial wrinkles appearance and were followed for 3 months post last

treatment. In order to assess safety, adverse events occurrence was monitored before and after each treatment and at follow up visits. In order to evaluate treatment efficacy, pre and post treatment photos were introduced to three uninvolved physicians for blinded evaluation based on Fitzpatrick Wrinkle and Elastosis scale.

Over 80% of the subjects showed at least one grade improvement in Fitzpatrick wrinkle score at three months follow-up post treatment based on objective evaluations of the baseline and three months follow-up photographs. There were no incidences of adverse effects or complications. As expected, mild to moderate erythema and mild edema were detected at the site of treatment immediately after treatment. All cases resolved without treatment within a few hours. Treatment was well tolerated with minimal to no pain in the majority of study subjects. The data reported in this study clearly indicates that the Stop U provides a safe and effective treatment for facial wrinkles.

Usability, Self-selection & Labeling Comprehension

Furthermore, Pollogen conducted a usability study for the STOP U device which was divided into two stages:

  • Stage one Self-Selection Study of the STOP U Device; 1.
    1. Stage two - Human Factors Validation of the Pollogen STOP U Device.

The Self -Selection study using the final STOP U packaging design produced a correct self-selection rate that met Pollogen's goal. The final packaging design promotes correct self-selection and adequately explains user eligibility to potential users in the real world.

61 subjects (39 female and 22 male) which had successfully identified themselves as potential device users participated in the Human Factors validation with 100% success rate. These results indicated that the design of the STOP U and its associated instructional materials facilitated safe use of the device.
