No
The device description and intended use focus on a continuous wave Doppler system for detecting blood vessels and a surgical kit. There is no mention of AI, ML, or any computational analysis of the Doppler signal beyond simple detection and output via loudspeaker.
Yes
The device is used for the "surgical treatment of the hemorrhoids of second and third degree" and includes components for performing ligation, indicating a direct therapeutic intervention.
Yes
The device uses a Doppler system to detect the terminal branch of the superior hemorrhoid artery. This act of detection and identification of a physiological structure, which guides the subsequent surgical treatment, constitutes a diagnostic function. The "Summary of Performance Studies" also references a guidance document for "Diagnostic Ultrasound Systems."
No
The device description clearly outlines hardware components including a Doppler detector, loudspeaker, light source, transducer, optical fibers, pneumatic foot pedal, proctoscope, sutures, needle holder, and knot tightener.
Based on the provided information, this device 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.
- Device Function: The THD Evolution Doppler guided proctoscope is a surgical system used during a surgical procedure to locate and ligate blood vessels (arteries) within the body. It uses Doppler ultrasound to guide the surgeon.
- No Sample Analysis: The device does not analyze samples taken from the patient's body. It directly interacts with the patient's tissues during surgery.
Therefore, the THD Evolution Doppler guided proctoscope falls under the category of a surgical device, not an in vitro diagnostic device.

Intended Use / Indications for Use
The THD Evolution Doppler guided proctoscope is a system for the surgical treatment of the hemorrhoids of second and third degree. It is based on Transanal Hemorrhoidal Dearterialization technique guided by a Doppler probe. The Doppler system, placed inside the THD Evolution device, is used to detect the terminal branch of the superior hemorrhoid artery, in order to perform ligation with a proctoscope, sutures and a needle holder included in the THD Kit.
The THD is to be used by physicians in hospitals, clinics, and physician's offices by prescription or doctor's orders.

Device Description
The THD consists of the THD Evolution Doppler Device and the THD Kit. The THD Evolution Doppler is a 8 MHz continuous wave (CW) Doppler detector with loudspeaker and a power light source. The THD Evolution Doppler must be used with dedicated accessories (Doppler transducer, optical fibers and pneumatic foot pedal), in order to facilitate surgical operation.
The THD Kit is a sterilized surgical kit comprised of a proctoscope, sutures, a needle holder and a knot tightener.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Acoustic output parameters measured for the THD Evolution are:
| MI | Ispta₃ (mW/cm²) | Wo (mW) | |
|---|---|---|---|
| Mean value | 0.027 | 232 | 15,633 |
| Standard Dev. | 0.0042 | 78 | 2,676 |
| Max Value: | 0.032 | 322 | 18,500 |
The results summarized in the table show that the THD Evolution is substantially equivalent in regards to acoustic performance to other devices legally marketed in United States and is below the upper limits recommended by the guidance "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers" September 30, 1997.

§ 892.1540 Nonfetal ultrasonic monitor.
(a)
Identification. A nonfetal ultrasonic monitor is a device that projects a continuous high-frequency sound wave into body tissue other than a fetus to determine frequency changes (doppler shift) in the reflected wave and is intended for use in the investigation of nonfetal blood flow and other nonfetal body tissues in motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)

Dear Ms. O'Connell:
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. 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 such 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.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled. "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html .
