摘要： A coiled endoluminal prosthesis system may include means for rotating a delivery catheter while axially releasing a coiled endoluminal prosthesis from the delivery catheter. A release element may be retracted simultaneously with rotation of the delivery catheter. The coiled endoluminal prosthesis may have a first direction of spiral in a first rotational direction. The delivery catheter may be rotated in a second rotational direction while axially releasing the coiled endoluminal prosthesis from the delivery catheter. The endoluminal prosthesis may be configured to reduce or eliminate any difference between the length of the endoluminal prosthesis when in the reduced diameter state and when in the expanded diameter state.

摘要： A delivery catheter comprises a first, flexible, polymer-based tube and a second, metal tube at the first tube distal end. The second tube has flexibility enhancing relief areas along its length to provide localized areas of reduced bending stiffness to enhance the bending flexibility while retaining good torsional stiffness. A notched catheter has a lumen and a notched outer surface intersecting the lumen with a filament-containing layer adjacent to the outer surface. A part of the filament-containing layer is capturable between the notched surface portion and an elongate element extendable through the lumen. A generally helically coiled endoluminal prosthesis may be mounted on a pre-torqued delivery catheter to tighten the coiled endoluminal prosthesis onto the delivery catheter.
摘要翻译：输送导管包括在第一管远端处的第一柔性聚合物基管和第二金属管。第二个管具有灵活性，增强沿其长度的减震区域，以提供弯曲刚度降低的局部区域，以提高弯曲柔韧性，同时保持良好的扭转刚度。缺口导管具有与内腔相交的内腔和切口外表面，与外表面相邻的含有细丝的层。含有细丝的层的一部分在凹口表面部分和可通过内腔延伸的细长元件之间被遮蔽。通常螺旋卷曲的腔内假体可以安装在预扭转的输送导管上，以将盘绕的腔内假体紧固到递送导管上。

摘要： Apparatus tests the durability of a peripheral artery medical device based upon anatomical loading conditions. A peripheral artery medical device is mounted to a support element, typically a hollow tube, having first and second end portions. End holding elements are mounted to a base and are secured to the first and second end portions. The apparatus further comprises means for applying a plurality of cycles of at least one of the following loading conditions to the medical device support element at the location of the peripheral artery medical device: torsion, tension/compression, bending and pinching. In some embodiments the apparatus comprises an environmental chamber housing at least the support element so to mimic the service temperature environment of the medical device. A method for testing the durability of a peripheral artery medical device based upon anatomical loading conditions is also disclosed.

摘要： A coiled ladder stent comprises first and second rails and rungs connecting the rails. At least one rung has lower strength portion or is an enhanced flexibility rung, or both. The lower strength portion is positioned at a reduced strength fracture location along the rung so to promote any fracture of the ladder stent at the fracture location along the rung to help prevent fracture of a rail. One way to make the lower strength portion is to make the cross-sectional area of the lower strength portion less than the average cross-sectional area of the rung. The enhanced flexibility aspect helps to accommodate relative movement between the first and second rails. Doing so helps to prevent fracture of the rails and rungs. In some embodiments of the invention the enhanced flexibility rung comprises one or more nonlinear, such as generally S-shaped or generally U-shaped, portions.
摘要翻译：盘绕的梯形支架包括连接轨道的第一和第二轨道和梯级。至少一个梯级具有较低的强度部分或是增强的柔性梯级，或两者。较低强度部分位于沿着梯级的减小的强度断裂位置，以便促进梯形支架在沿着横梁的断裂位置处的任何断裂，以帮助防止轨道断裂。制造低强度部分的一种方式是使下部强度部分的横截面面积小于梯级的平均横截面面积。增强的灵活性方面有助于适应第一和第二轨道之间的相对运动。这样做有助于防止轨道和梯级断裂。在本发明的一些实施例中，增强的柔性梯级包括一个或多个非线性，例如大致S形或大致U形的部分。
