    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 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 stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. A trigger wire is adapted to be coupled to at least one of the proximal apices to restrain a proximal end of the stent during delivery. In a first embodiment, a first proximal apex comprises a bore for receiving the trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. The trigger wire therefore is only coupled to selected ones of the proximal apices. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

    摘要： An introducer assembly for introducing a stent-graft or other device into a vessel of a patient is provided with a dilator tip which is naturally curved, preferably to be substantially a U-shape. The dilator tip is flexible so as to be able to become substantially straight with a guide wire therein and yet to be able to curve back towards its natural curvature during deployment of an implant. The curvature of the dilator tip can ensure that the dilator tip does not cause damage to the vessel wall during deployment of an implant carried thereon, as can occur with straight dilator tips.
