Apparatus and method for stenting a vessel using balloon-actuated stent with interlocking elements

摘要

Vascular support device (apparatus for stenting a vessel) of the present invention includes a stent (stent) with a grid (lattice) of substantially limited the connecting element in a cylindrical shape having a first open end and second open end, and wherein the grid is switchable between the closed configuration and the open configuration. In the first embodiment, the stent comprises a plurality of connecting bridges (interlocking bridge). In the second embodiment, the stent comprises a plurality of connecting column (interlocking strut). The apparatus comprises a catheter having a portion for the inner sleeve and the expansion sleeve member on the inside, the inflatable member may be switched between a collapsed state and the expanded state. In certain embodiments, the stent is that the expansion member is in the collapsed state and is fixed to the expansion member over the catheter when the stent is in a closed shape. The stent is separated from the catheter when the stent and an opening shape in the expanded state the expansion member. In addition, a method for supporting a blood vessel of the present invention involves placing the stent in a desired position in the embodiment two kinds of blood vessel. ; Vessels, grids, stents, connecting bridge, connecting column, catheters
