METHOD AND DEVICE FOR ENDOLUMINAL TREATMENT OF BLOOD VESSEL Russian patent published in 2014 - IPC A61B18/18 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, specifically phlebology. Before operation, a treated vessel is divided into segments. All varicose inflows are marked. With a probe inserted into the blood vessel, its tractive resistance is measured in all the segments. Measured longitudinal forces are plotted in all the segments along the full length of the vessel treatment. That is followed by ablation by executing reciprocating motions of a heating element at a certain segment of the vessel. That is combined with measuring an actual resistance to the probe motion, and the pre-measured tractive resistance is subtracted therefrom, and a difference of forces shows the quality of the vessel treatment. The probe operation is controlled by a computer. A device for endoluminal treatment of the blood vessel comprising the probe with the heating element provided with a heating temperature sensor and connected by a power cable inside a rod with a power source; a proximal end of the probe is mounted in a feeding guide mounted on a fixed support, and provided with a flexible protective guide channel, one end of which is fixed on the above guide, while another end - on the patient's body; the flexible end of the probe is placed inside the guide channel and placed between driving and measuring spring-loaded rollers.

EFFECT: group of invention enables providing higher quality of the vessel treatment, reducing a risk of complications by controlling an exposure temperature.
