The invention relates to the medical equipment, in particular to controlled catheters, and may be used in neurosurgery.The controlled catheter comprises a tube (1) of elastic material, consisting of working and non-working parts, guide threads (4), connecting the working part of the tube (1) with thread tensioning mechanisms (4), mounted on the non-working part of the tube (1), and also a wound cylindrical spring (3). The end of the working part of the tube (1) is made blunt with through holes (1). The spring (3) is placed around the working part of the tube (1). The coils of the spring (3) are made with a defined pitch, at the same time in the first coil (3) of the spring (3), on the side of the blunt end, are made four bends, uniformly placed around its circumference, for the fixation thereon of four threads (4), placed between the tube (1) and the spring (3). Additionally, in the non-working part of the tube (1) along it is installed a guide rod (2), rigidly connected to the last coil of the spring (3). The spring (3) is covered with an additional tube (5). The thread tensioning mechanisms (4) are made with the possibility of regulating the amount of tension and are equipped with control knobs (11).Invenţia se referă la utilajul medical, în special la catetere ghidate, şi poate fi utilizată în neurochirurgie.Cateterul ghidat include un tub (1) din material elastic, care constă din părţi de lucru şi nefuncţională, fire (4) de ghidare, care leagă partea de lucru a tubului (1) cu mecanisme de tensionare a firelor (4), montate pe partea nefuncţională a tubului (1), precum şi un arc (3) spiralat cilindric. Capătul părţii de lucru a tubului (1) este executat bont cu orificii (1) străpunse. Arcul (3) este amplasat în jurul părţii de lucru a tubului (1). Spirele arcului (3) sunt executate cu pas determinat, totodată în prima spiră (3) a arcului (3), din partea capătului bont, sunt executate patru curburi, amplasate uniform pe circumferinţa acesteia, pentru fixarea pe ele
