    • A flexible, steerable intravascular catheter includes an elongate flexible shaft having a heterogeneous or multi-zone stiffness profile or structure. A first or distal portion of the catheter shaft may have a substantially constant or distinct stiffness or flexibility, a second, intermediate or transition section is proximal relative to, and less flexible than, the first section, and a third section is proximal relative to, and also less more flexible than, the first section. The third section also includes a substantially constant or distinct stiffness or flexibility. The flexibility or stiffness of the second section varies along its length, e.g., in a substantially linear, step-like or ramp-like manner to provide a smooth or gradual transition between the stiffness of the first or distal section and the flexibility or stiffness of the third or proximal section.
    • 柔韧的,可操纵的血管内导管包括具有异质或多区域刚度分布或结构的细长柔性轴。 导管轴的第一或远端部分可以具有基本上恒定或不同的刚度或柔性,第二中间或过渡部分相对于第一部分近端并且比第一部分更柔性,并且第三部分相对于第二部分近端, 并且也比第一部分更不灵活。 第三部分还包括基本上恒定或不同的刚度或柔性。 第二部分的柔韧性或刚度沿其长度变化,例如以基本线性的阶梯状或斜坡状方式变化,以提供第一或远端部分的刚度之间的平滑或逐渐过渡,以及柔性或刚度 第三或近端部分。

    • This invention in the broadest sense comprises a ski boot, freely pivoting at the ankle, in combination with an adjustable suspension shock absorber to control and optimize compression and rebound damping characteristics. In the preferred embodiment, the ski boot would comprise a rigid, pivoting exoskeleton (providing the lateral stiffness and torsional control), a sub-boot (providing padding, thermal insulation, and water-proofing), and a fully adjustable pneumatic/hydraulic/spring suspension system (providing adjustable fore-aft stiffness, shock absorption, and rebound damping). The object of the invention is to optimize ski boot performance by separating the necessary boot components, allowing them to be designed to optimize different performance characteristics.
    • 本发明在最广泛的意义上包括滑雪靴,在脚踝处自由枢转,与可调节的悬挂减震器组合,以控制和优化压缩和回弹阻尼特性。 在优选实施例中,滑雪靴将包括刚性的枢转外骨骼(提供侧向刚度和扭转控制),副靴(提供衬垫,隔热和防水)以及完全可调的气动/液压/ 弹簧悬挂系统(提供可调节的前后刚度,减震和回弹阻尼)。 本发明的目的是通过分离必需的引导部件来优化滑雪靴性能,从而允许它们被设计成优化不同的性能特征。
