摘要： A strut, or beam, is provided for intraluminal devices. Strain which is introduced into a stent or other intraluminal device is distributed more evenly along the length of the improved strut by maintaining a substantially constant strain level along the length of an end portion. This may increase fatigue life or improve the performance of devices using the improved strut. The strain along the length of the end portion may be maintained substantially constant by varying a section property of the strut, including the width, thickness, cross-sectional area, material property or other characteristic of the end portion.
摘要翻译： 为管腔内装置提供支柱或梁。 通过沿着端部的长度保持基本恒定的应变水平，被引入支架或其他管腔内装置的应变沿着改进的支柱的长度更均匀地分布。 这可能会增加疲劳寿命或提高使用改进支柱的设备的性能。 通过改变支柱的截面性能，包括端部的宽度，厚度，横截面面积，材料特性或其他特性，沿端部长度的应变可以保持基本恒定。

摘要： A balloon expandable covered stent consists of a plurality of primary stent units, each having an undulating shape defined by a series of primary strut members converging to form peaks and valleys. The primary stent units are assembled into a single cylindrical structure of the stent by connecting corresponding peaks with secondary strut members. Generally, surfaces of the stent may then coated with a polymeric, hyper-elastic material, preferably Thoralon®, by pre-expanding the stent prior to coating.

摘要： The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

摘要： A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve.

摘要： A self-expanding medical device delivery system includes a plurality of trigger wires. The trigger wires retain a self-expanding medical device by forming a bend about structural members located on the proximal portion of the medical device. The proximal portions of the trigger wires have a greater diameter than the distal portions of the trigger wires to provide increased bending strength. An operator releases the self-expanding medical device by withdrawing the trigger wires in the distal direction. In some embodiments, a small portion at the proximal end of each trigger wire has a smaller diameter than the rest of the proximal portion. In other embodiments, the proximal and distal portions of each trigger wire each have a greater diameter than the center of the trigger wire.

摘要： The present embodiments provide a valve for implantation in a patient, for example, an aortic valve. The valve comprises a proximal region comprising a cylindrical shape, and a distal region having a generally rectangular shape comprising opposing flat surfaces that are separated by narrower flat sides. A tapered region is disposed between the proximal and distal regions, where the tapered region comprises two opposing flat surfaces that transition into the opposing flat surfaces of the distal region. The opposing flat surfaces of the tapered region are angled relative to the proximal and distal regions. The opposing flat surfaces at the distal end of the valve allow fluid flow therethrough during antegrade flow and are generally adjacent to one another to inhibit blood flow through the valve during retrograde flow. Optionally, at least one reinforcement member may be coupled to the valve to prevent prolapse of the valve during retrograde flow.

摘要： A stent graft has a tubular side arm which can be angled proximally and distally and from side to side. The wall of the stent graft in the vicinity of the side arm has a loose fold of the graft material and the side arm is fastened to the loose fold of graft material. The tubular side arm has an inner end and an outer end and is fastened into the loose fold of graft material by a circumferential fastening around the tubular side arm between the inner end and the outer end so that the tubular side arm extends partially within the tubular body of the stent graft and partially outside the tubular body of the stent graft. The loose fold of graft material can be formed by the graft material defining a recess in the wall of the stent graft. To enable movement or angulation proximally and distally and from side to side the loose fold of graft material is provided both proximally and distally of the tubular side arm and circumferentially to each side of the tubular side arm.
