METHOD FOR REMOVING OCCLUSION OF CORONARY ARTERY Russian patent published in 2007 - IPC A61M25/10 A61F2/06 

FIELD: medicine, cardiosurgery.

SUBSTANCE: the present innovation deals with reconstructing permeability of occluded coronary arteries due to removing occlusion out of affected parts of arteries. So, a coronary guide with a soft tip should be applied to achieve the site of occlusion by not entering a lateral artery. As balloon catheters one should apply two-lumen ones, moreover, the first is designed to be shortened from its distal edge and ends with a balloon segment. The present balloon catheter should be applied up to the site of occlusion onset and simultaneously up to bifurcation region to install it, to be blown up to overlap the mouth of lateral artery. Then a rigid direct guide should be applied along the same balloon catheter - according to its conduit mine after preliminary removing a coronary guide with a soft tip. After directing this rigid guide through occlusion into distal part of occluded main artery and its recanalization with it is important to remove the first modeled balloon catheter and apply the second balloon catheter instead. It should be moved along occlusion to reach the center and dilate the artery. In particular case, one should remove a two-lumen tip by not interrupting the hermetic nature of a balloon catheter. The innovation enables to remove occlusion of the main artery in the site of branching, exclude "falling down" of coronary guide into lateral artery and, thus, provide the disposition of coronary guide especially in the stump in occluded artery and obtain its central position and movement strictly along the center of occlusion avoiding vascular wall traumatism due to subintimal application of coronary guide and, also, avoid arterial perforation in the site of occlusion.

EFFECT: higher efficiency.
