FIELD: medical equipment.
SUBSTANCE: stepped balloon catheter comprises a balloon, catheter feeds to the balloon, which allow creating a pressure in the balloon, and a central lumen for the guide wire. Balloon is divided into segments and each segment has separate supply for creation of pressure and wherein the balloon in the expanded state has at least two zones with different diameter, and wherein these zones pass into each other with the step. Segments accordingly represent individual cylinders, point-welded to each other.
EFFECT: technical result is to provide the possibility of accurately locating the stents in the branched vessels and if necessary, also to be connected to stent located in main branch by means of fenestration with account of tapering diameter of branching vessel.
