20120116500 | H-Side Branch Stent - Provided is an H-side branch stent including a first stent having a plurality of cells and a hollow cylindrical shape, at least one bridge having one end connected to a distal end of the first stent, and a second stent having a front end connected to the other end of the bridge, and having a plurality of cells and a hollow cylindrical shape. Accordingly, the H-side branch stent can prevent re-stenosis of the opening of the branch blood vessel since the stent can completely support an inner circumference of an opening of a branch blood vessel in a circumferential direction, and prevent blood flow disturbance because stents are not densely concentrated to a boundary between a main blood vessel and the branch blood vessel and some regions of the stent do not project into the main blood vessel. | 05-10-2012 |
20120283821 | Stent for Protecting Bifurcated Blood Vessels in Bifurcation Lesion - The present invention relates to a stent for protecting a branch blood vessel at a branch-point lesion. The stent is inserted into and widened in a main blood vessel having the branch blood vessel extending in a slant from the branch-point lesion, thereby simultaneously expanding the main blood vessel and providing a smooth flow of blood towards the branch blood vessel. As a result, it is possible to simultaneously expand the main blood vessel and to sufficiently secure a passage from the main blood vessel towards the branch blood vessel. As such, the flow of blood is kept smooth. Further, after the stent is inserted into the main blood vessel, another stent, a guide wire, and related tools and catheter can be inserted in the direction of the branch blood vessel in a more accurate manner. | 11-08-2012 |
