    摘要： The present invention relates to a device for introduction into a body, the device assuming within the body a predefined shape, the device comprising: an elongated element (10) formed primarily from a plurality of segments (12) sequentially interconnected so as to form an effective hinge (14) between adjacent of the segments; and a substantially straight elongated-element-restricting structure (20) fitting to the shape of said elongated element in a straightened configuration; wherein the segments and the effective hinges are configured such that: (a) when the elongated element is confined to a substantially straight state, the effective hinges transfer compressive forces from one segment to the next so that the elongated element can be pushed so as to advance along said elongated-element-restricting structure (20); and (b) when the elongated element is not confined by said elongated-element-restricting structure (20), the effective hinges allow deflection of one segment relative to the next segment until at least one abutment surface of each segment comes into abutment with at least one corresponding abutment surface of the next segment, thereby defining a fully flexed state of the elongated element, the fully flexed state corresponding to a predefined shape of the elongated element.

    摘要翻译： 本发明涉及一种用于引入到身体中的装置，该装置在身体内呈现预定的形状，该装置包括：细长元件（10），主要由多个片段（12）形成，所述多个片段顺序互相连接以形成 有效铰链（14）在相邻的段之间; 以及基本上直的细长元件限制结构（20），其以矫直构造适合所述细长元件的形状; 其中所述段和所述有效铰链被构造成使得：（a）当所述细长元件被限制在基本上直的状态时，所述有效铰链将压缩力从一个区段传递到下一个区段，使得所述细长元件可被推动以便 沿着所述细长元件限制结构（20）前进; 和（b）当所述细长元件不受所述细长元件限制结构（20）限制时，所述有效铰链允许一个段相对于下一段的偏转，直到每个段的至少一个邻接表面与 至少一个对应的邻接表面，从而限定细长元件的完全弯曲状态，完全弯曲状态对应于细长元件的预定形状。
