DEVICE FOR DISOBSTRUCTION OF ATERIOSCLEROTIC LESIONS WHICH INCORPORATE THE ORIGIN OF LATERAL BRANCHES, OR WHICH ARE LOCATED IN BIFURCATION OF THE CORONARY CIRCULATION, AND RESPECTIVE INTERVENTIONIST PROCESS OF PLACING SUCH DEVICE

摘要

A device, for disobstructing ateriosclerotic lesions in proximity to the origin of lateral branches or bifurcations of an artery. The device includes a stent having two sections. One section is adhered along approximately two thirds of its total length to a balloon. The other section corresponds to the final third of the length of the stent does not completely adhere to the balloon and is partially expanded before its use. A proximal end of a metallic guide wire passes through the mesh of the partially expanded section which has been previously introduced into a secondary branch or bifurcation in the artery. The wire provides an access to the secondary branch for introducing a second balloon or a second stent for the disobstruction of the secondary branch or bifurcation.
