    Abstract: An occlusion bypassing apparatus is disclosed for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The apparatus includes an outer shaft component, an inner shaft component disposed within the outer shaft component, and a needle component slidably disposed within the inner shaft component. The inner shaft component includes a body portion and a needle housing, which is distal to the body portion. The needle housing is less flexible than the body portion. In order to smooth the transition between the body portion and the needle housing, the needle housing includes a transition portion that has a variable flexibility along its length that decreases in a distal direction. A curved distal end of the needle component is distally advanced relative to the inner shaft component to pierce through the intima of the vessel and thereafter enter the true lumen.

    Abstract translation: 公开了一种闭塞旁路装置，用于在血管旁路旁路容器内的闭塞后重新进入容器的真腔。 该装置包括外轴部件，设置在外轴部件内的内轴部件和可滑动地设置在内轴部件内的针部件。 内轴部件包括主体部分和在主体部分的远侧的针壳体。 针壳体比主体部分柔韧性好。 为了平滑主体部分和针壳体之间的过渡，针壳体包括过渡部分，其沿其长度具有沿远端方向减小的可变柔性。 针部件的弯曲远端相对于内轴部件向远侧前进以刺穿血管的内膜，然后进入真腔。
