The THD Slide One 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 system, placed inside the THD Evolution Doppler device, is used to detect the terminal branch of the superior hemorrhoid artery, in order to perform ligation with a THD proctoscope, sutures and a needle holder included in the THD Kits.

The THD Slide One is to be used by physicians in hospitals, clinics, and physician's offices by prescription or doctor's orders.

Regulation Number and Section

§ 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)
Classification. Class II.
