摘要： Ce dispositif comporte un corps monobloc (10) creux, allongé, constitué d'un maillage expansible radialement, et comprenant des parties terminales principale (20) et secondaire (30) et une partie intermédiaire (40). La partie terminale principale présente une forme tubulaire, inclut une première extrémité (21) centrée sur un premier axe (X21) et ayant une section transversale circulaire, et a une section transversale qui, en projection orthogonale sur un plan géométrique contenant la section transversale de la première extrémité, reste inscrite dans cette dernière lorsqu'on la parcourt de sa première à sa seconde extrémité (22). La partie terminale secondaire (30) présente une forme cylindrique centrée sur un second axe (X30), parallèle et décalé par rapport au premier axe, et a une section transversale qui est circulaire et qui, en projection orthogonale sur le plan géométrique, est inscrite dans la section transversale de la première extrémité. La partie intermédiaire (40) présente une raideur radiale supérieure à celles des parties terminales principale et secondaire, et délimite une ouverture principale (43) ajustée à la seconde extrémité, une première ouverture secondaire (44) ajustée à une seconde extrémité (32) de la partie terminale secondaire, et une seconde ouverture secondaire (45) qui interrompt le maillage du corps.

摘要： A stent comprises a framework that includes a sequence of cells that each occupy a discrete segment of the stent length, and each of the cells includes a plurality of struts with ends connected at respective vertices. In some forms the hollow cylindrical shape of the framework is moveable among a loading diameter that is smaller than a tube diameter, which is smaller than an expanded diameter, and every strut of the framework is oriented parallel to the stent axis when the hollow cylindrical shape is at the tube diameter. In other forms the framework includes T-bars that connect adjacent cells, where the T-bars have a column that has a minimum width perpendicular to the long axis that is wider than a maximum width of each of the struts, and the column defines at least one slot. In still other forms, the framework exhibits geometries that facilitate a high packing density for the framework when the stent is in a compressed tube or loading configuration.

摘要： Graft devices are provided addressing a long need for off-the-shelf small diameter replacement vessels to overcome the drawbacks of currently available alternatives. As they are available off- the-shelf, the graft devices do not require additional surgery to harvest it such as for a vein graft. A porous nature of the graft devices enables restoration process, which results in new natural and patient-own tissue, in contrast to currently existing vascular prosthesis that can never fully heal. A built-in graft support device overcomes the limited kink-resistance that is typical for these kinds of (electrospun) porous devices. A zigzag pattern with alternating laminating and non-laminating areas enables the incorporation of the graft support device without the need for additional suturing or connecting the inner and outer layer for good lamination, while maintaining adequate kinkresistance.

摘要： The invention is directed to an endovascular device having an undulating pattern of struts and loops, where at least one strut has a bend in the crimped profile for reducing the compressed diameter. The strut configuration comprises one or more bent sections facing in opposite convex and concave orientations, thereby creating a space or hollow for an oppositely aligned portion of the device to nestle therein as the device is compressed. The undulating pattern may be staggered such that adjacent loops in the helical direction are axially offset with respect to a perpendicular axis perpendicular to the lengthwise direction, where a loop may be positioned to align with an adjacent strut in the helical direction. The device may include struts of varying lengths which may contribute to an enlarged expanded diameter of the device. The bent strut design of the crimped profile may be used with any endovascular strut design.

摘要： Various examples address support structures (e.g., prosthetic valve support structures or frames) that incorporate a frame that, upon transitioning to a deployed configuration, include a proximal section has increased stiffness, or resistance to deformation in a transverse plane to a longitudinal axis of a device, including resistance to a change in shape, size, or both. Such an increase in transverse deformation resistance may be measured as an increase in radial compressive resistance or an increase in flat plate stiffness, for example, or both. Such increases in transverse deformation resistance may be realized through a reduction in length of the increased stiffness region of the support structure, such as through longitudinal compression of the region following an initial radial expansion of the region.

摘要： Described herein are radially self-expanding stents. The disclosed stents can be used to widen arteries and/or veins of a patient to counteract or combat narrowing of the arteries and/or veins associated with certain congenital diseases, such as aortic coarctation. As an example, the disclosed stents are configured to be placed at or near a narrowed portion of the aorta where the stent produces a radial outward force on the aorta. The radial force produced by the stent widens the aorta and causes the stent to expand with the aorta. The disclosed stents can be crimped to relatively small sizes for placement in small patients (e.g., less than about 10 kg in size) and can be configured to expand to widen the aorta and to accommodate growth in the patient.
