Abstract: A method for treating a body conduit/lumen having an undesired reduced diameter includes determining a target diameter of the conduit/lumen in a target location of the conduit/lumen, and delivering a self-expanding metal stent in a contracted configuration to the target location. In a fully expanded configuration, the stent has a diameter that is more than 50% larger than the target diameter over an entire length of the self-expanding stent.

Abstract: A system includes: a stent having a proximal end; a support including the stent engaged thereon, having a longitudinal axis and being equipped with a stop against which the proximal end is applied; a sheath having a distal end, which can slide relative to the support and stop, between a distal overlap position of the stent and a proximal release position for deploying the stent, and a first inflatable balloon situated between the support and stent, including a distal portion that protrudes past the distal end, on the distal side thereof when the latter is in the distal position, and having, on the distal side, a transverse section larger than or equal to that of the sheath, the distal end situated back from the distal end in the proximal direction, and situated opposite the distal portion, such that the distal portion protrudes partially past the distal end of the sheath.

Abstract: A device and method for treating a body conduit/lumen having an undesired reduced diameter include delivering an expandable stent in a contracted configuration to a target location. The stent has small cells that form an open tight mesh providing the effective capture of small particles such as thrombi. Preferably, the tight mesh is combined with structure that permits creation of large side openings to accommodate lumen branches.

Abstract: A frangible bridge structure for a stent includes three successive branches, a first of which is connected to one of the stent portions which the bridge structure makes it possible to connect and a second of which is connected to the other of the stent portions which the bridge structure makes it possible to connect, these first and second branches being connected, by two connecting portions, to a third intermediate branch, between the first and second branches, these three branches extending parallel to each other with the longitudinal direction of these branches preferably being oriented perpendicular to the longitudinal direction of the stent, and in immediate proximity to each other.

Abstract: A device for deploying a stent, is connected to a catheter, the catheter being equipped with support structure for supporting the stent and with a deployment mechanism for deploying this stent. The device includes a portion connected to the stent-supporting structure and a portion connected to the stent-deploying mechanism. According to embodiments of the invention, the portion connected to the stent-supporting structure is in the form of a handle which may be grasped by a hand of the user, including at least one boss allowing it to be supported on a relatively stable surface, such as the operating table, the height of this boss being such that this support may be achieved in spite of the presence of the fingers of the user around the handle.
