摘要： A remotely steerable guidewire, catheter or insertable active implement (10) is disclosed. A steerable guidewire or a catheter for coronary and peripheral catheterizations is illustrated, using electrostrictive or piezoelectric material for controlling its motions inside the body via control inputs (18) applied from outside the body. A steerable portion of the device, which may be either an active flexible tip (16) or an active region (14) along the length of the implement, controls the tip position or modifies stiffness along a region of the tip. In one embodiment, manipulation of electrical control inputs permits deflection of the steerable region through a range of motion about the axis of the implement in a single plane. In further embodiments, the tip may deflect in multiple planes about its longitudinal axis, or the device may be selectively stiffened to assume an arc shape or to firmly lodge the tip in position in a vessel.

摘要翻译：公开了一种可遥控的导丝，导管或可插入的主动器具。示出了用于冠状动脉和周边导管插入术的可导向导丝或导管，其使用电致伸缩或压电材料来通过从身体外部施加的控制输入来控制其在体内的运动。装置的可操纵部分，其可以是沿着工具的长度的主动柔性尖端或活动区域，其控制尖端位置或改变尖端的区域的刚度。在一个实施例中，电控制输入的操作允许可操纵区域在单个平面内通过围绕工具的轴线的运动范围的偏转。在另外的实施例中，尖端可以围绕其纵向轴线在多个平面中偏转，或者该装置可选择性地加强成呈弧形或将尖端牢固地保持在容器中的适当位置。
