    摘要： A stent (1) for deployment in a blood vessel which is movable between an unloaded straight cylindrical state and a loaded curved state. The stent (1) is bendable between a first loaded configuration when the blood vessel is in the unloaded state, and a second loaded configuration when the blood vessel is in the loaded state. The stent (1) has an unloaded configuration which is intermediate the first loaded configuration and the second loaded configuration. Because of the unloaded configuration of the stent (1), the degrees of deformation which the stent (1) undergoes are minimized leading to minimized strains, increased fatigue life, and reduced risk of fracture.

    摘要翻译： 一种用于展开在血管中的支架（1），其可在未加载的直圆柱状状态和加载弯曲状态之间移动。 当血管处于无负载状态时，支架（1）可在第一负载构型之间弯曲，并且当血管处于负载状态时，支架（1）可弯曲。 支架（1）具有在第一加载配置和第二加载配置之间的卸载配置。 由于支架（1）的卸载构造，支架（1）经历的变形程度被最小化，从而导致最小化的应变，增加的疲劳寿命和降低的骨折风险。

    摘要： A stent deployment device comprises an elongate catheter shaft (2), and an inflatable balloon (3). The inflatable balloon (3) is movable between a collapsed configuration and an expanded configuration. In the expanded configuration part of the longitudinal axis of the balloon (3) is curved in three-dimensional space, and part of the balloon (3) is helically shaped. A stent (6) is movable from a collapsed delivery configuration to a partially expanded intermediate configuration, and subsequently from the intermediate configuration to a fully expanded deployed configuration. In the delivery configuration the longitudinal axis of the stent (6) is straight. The longitudinal axis of the stent (6) may be straight or curved in three-dimensional space in the intermediate configuration. In the deployed configuration the longitudinal axis of the stent (6) is curved in three-dimensional space. The balloon (3) in the expanded configuration exerts force on the stent (6). In the deployed configuration the stent (6) in turn exerts force on the internal wall of a blood vessel (5) causing the longitudinal axis of the blood vessel (5) to curve in three-dimensional space.

    摘要： A stent deployment device comprises an elongate catheter shaft (2), and an inflatable balloon (3). The inflatable balloon (3) is movable between a collapsed configuration and an expanded configuration. In the expanded configuration part of the longitudinal axis of the balloon (3) is curved in three-dimensional space, and part of the balloon (3) is helically shaped. A stent (6) is movable from a collapsed delivery configuration to a partially expanded intermediate configuration, and subsequently from the intermediate configuration to a fully expanded deployed configuration. In the delivery configuration the longitudinal axis of the stent (6) is straight. The longitudinal axis of the stent (6) may be straight or curved in three-dimensional space in the intermediate configuration. In the deployed configuration the longitudinal axis of the stent (6) is curved in three-dimensional space. The balloon (3) in the expanded configuration exerts force on the stent (6). In the deployed configuration the stent (6) in turn exerts force on the internal wall of a blood vessel (5) causing the longitudinal axis of the blood vessel (5) to curve in three-dimensional space.
