FIELD: medical equipment. ^ SUBSTANCE: catheter has flexible catheter tube and device for controlled deviation of distal end part of catheter tube. Device for controlled deviation of distal end part of flexible catheter tube is made in form of wire conductor made of springing elastic material. Conductor is capable of free moving along catheter tube into neutral position or initial position. As a result, when conductor is more or less pulled in relatively its initial position, end part of flexible catheter tube does move. Conductor has twisted spiral-shaped end part which when being in neutral or initial position takes place directly in opposition to external end of catheter tube. As a result, when wire conductor is pulled in relatively its initial position inside flexible tube, the end part of tube deflects at adjusted angle under influence of compression power of twisted spiral-shaped end part, which straightens forcedly. ^ EFFECT: minimal invasive surgery; ability of controlling catheter tube outside patient's body. ^ 5 cl, 2 dwg |
