Stent delivery assembly for treating bifurcations |
摘要 |
<p>An apparatus and method is provided for stenting bifurcated vessels. A proximal-angled stent (10) is configured for implanting in a side-branch vessel (5) wherein the proximal-angled stent (10) has an angulated portion that corresponds to the angle (18) formed by the intersection of the side-branch vessel (5) and the main vessel (6) so that all portions of the side-branch vessel (5) at the bifurcation are covered by the proximal-angled stent (10). A main-vessel stent (60) is provided for implanting in the main vessel (6), wherein the main-vessel stent (60) has an aperture or stent cell that aligns with the opening to the side-branch vessel (5) to permit unobstructed blood flow between the main vessel (6) and the side-branch vessel (5). Side-branch and main-vessel catheter assemblies are advanced over a pair of guide wires (41A,36A) for delivering, appropriately orienting, and implanting, the proximal-angled stent (10) and the apertured stent. <IMAGE></p> |
