## Indications for Use

The THD Procto Software is a software that can be used: · In endoanal ultrasound (EAUS), in order to help evaluate pelvic floor disorders by processing and recording images of tissue structures in the pelvic region with the aid of a dedicated ultrasound probe. This is done by inserting the probe into the anal canal, acquiring the ultrasound signal and letting the software process the image. · In Anoscopy exams in order to record images and videos of the anorectal channel, which are acquired through a dedicated video camera that provides images with a resolution greater than 1.1 MPx through USB protocol

## Device Story

Diagnostic system for pelvic floor disorders; utilizes dedicated endoanal ultrasound probe and video camera. Inputs: ultrasound signals from probe; video/images from camera via USB. Software processes signals into 2D echographic images/videos; enables real-time or post-processing (notes, zoom, measurements). Outputs: recorded images, videos, and examination reports (medical history, conclusions, printing). Used in clinical settings by healthcare professionals. System comprises three modules: Medical Report (database management), Endoanal Ultrasound, and Anoscopy Exams. Facilitates clinical decision-making through visualization and documentation of anorectal/pelvic structures.

## Clinical Evidence

Bench testing only. No clinical data provided.

## Technological Characteristics

Standalone software running on COTS Windows OS. Interfaces with USB-based endoanal ultrasound probe and video camera (>1.1 MPx). Functions include 2D image processing, distance/area/angle measurements, and report generation. Class II device.

## Regulatory Identification

An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Filippo Bastia:

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, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

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); medical device reporting of medical device-related adverse events) (21 CFR 803) for

{1}------------------------------------------------

devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

- Medical Report (Launcher) module, which contains the functions for the management of . the patient database and of the Exams database. Patients and Exams databases support the operation of the remaining macro modules (Endoanal Ultrasound Module and Anoscopy Exams Module) that are listed below
- . Endoanal Ultrasound Module, which manages:
	- The acquisition of the ultrasound signal from the probe and its processing to o transform it into a two-dimensional echographic image / video
	- Any image / video processing (application of notes, zoom, measurements, etc.) in o real-time (during the exam) or post-processing,
	- The examination report (medical history, comments, conclusions) and the printing O
- Anoscopy Exams module, which manages:
	- Capturing images and video from the video camera via standard USB protocol. o Images are then recorded and displayed on the computer screen
	- Any image / video processing (application of notes, zoom, measurements, etc.) in O real-time (during the exam) or post-processing
	- The examination report (medical history, comments, conclusions) and the printing o
