Intended Use
The MONARCH 21 system's intended use is to measure sexual response to visual and auditory stimuli in male sexual offenders as an important part of evaluating individual treatment need and determining risk for recidivism.
Device Description
MONARCH 21 Penile Plethysmograph consists of attached sensors, which measure penile tumescence. A laptop computer is used to store, tabulate, display and print out the acquired data.
More Information

Not Found

No
The description focuses on sensor data acquisition and basic data processing (store, tabulate, display, print). There is no mention of AI/ML terms or complex analytical methods that would typically indicate AI/ML use.

No
The device is used to measure sexual response for evaluation and risk assessment, not to treat or cure a disease or condition.

Yes
The device is used to measure sexual response to stimuli to evaluate treatment needs and determine recidivism risk, which is a diagnostic purpose.

No

The device description explicitly states it "consists of attached sensors, which measure penile tumescence," indicating hardware components beyond just software.

Based on the provided information, the MONARCH 21 system is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • MONARCH 21 Function: The MONARCH 21 system measures a physiological response (penile tumescence) directly from the body using external sensors. It does not analyze samples taken from the body.
  • Intended Use: The intended use is to measure a physiological response as part of a behavioral evaluation, not to diagnose a disease or condition based on analysis of a biological sample.

Therefore, the MONARCH 21 system falls outside the scope of In Vitro Diagnostics.

Technological Summary between MONARCH 21 and its predicate device

MONARCH 21 provides all the functionality of it's predicate devices into a truly portable and easy-to-use system. Differences between MONARCH 21 and predicate devices were subjected to mechanical, electrical safety, software testing and clinical validation to demonstrate that they do not diminish safety and effectiveness. Intercom and auxiliary traces support technicians in making standardized assessments. Non-standardized assessment capability is available for research.

Non-Clinical Test Results

A precision machined aluminum calibration cone with graduated circumference sizes was used to measure the penile sensors full range of values. Secondary agents were tested using simulated equivalent values. All testing mimicked prior predicate device examination resulting in substantial equivalence.

Dear Ms. Olsen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, nuarket the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
