DEVICE FOR MATERIAL REMOVAL AND METHOD FOR USING Russian patent published in 2015 - IPC A61M25/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. A catheter has a tubular body and a rotatable rod integrated into the tubular body cavity. A cutting element is connected to the rotatable rod and has a cutting edge. The cutting element and the rotatable rod are configured to move longitudinally inside the tubular body between the retracted position, wherein the cutting element is parallel to a long axis of the tubular body, and the cutting position, wherein the cutting element is deflected between the proximal and distal ends of the tubular body beyond an outer diameter of the tubular body. The cutting element is configured to cut the material from a vascular wall on the processed section as pushing the catheter in the distal direction through the processed section. The catheter comprises a collection chamber arranged in the proximal direction in relation to a cutting window.

EFFECT: structural improvement.
