FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine and can be used for the restoration of an adequate passage or opening a passage through a vascular occlusion. The device uses a tension element and a spring-assisted element, e.g. a compression spring for oscillations. The system comprises a device and a control unit for adjusting the motion frequency and amplitude of the oscillation element.
EFFECT: device and system can be used for passing through the complete or partial vascular occlusion and for improving the catheter passage through a partially occluded vessel or a bending vessel.
