摘要:
A device for ablating cardiac tissue includes a plurality of ablation elements substantially aligned along a common axis and adjustable between first and second predetermined positions. In the first predetermined position, the plurality of ablation elements form a curved contact surface. In the second predetermined position, the plurality of ablation elements form a substantially straight insertion configuration. At least one hinge (27) may connect adjacent ones of the plurality of ablation elements (26). Each of the plurality of ablation elements may be located within a housing (29), which may have at least a portion of a hinge integrally formed therewith to connect adjacent ablation elements. Alternatively, a strand of superelastic material (38), such as a Nitinol wire, may interconnect ablation elements. The superelastic material may bias the plurality of ablation elements into at least one of the first and second predetermined positions.
摘要(中):
用于消融心脏组织的装置包括多个消融元件,其基本上沿公共轴线对准并且可在第一和第二预定位置之间调节。 在第一预定位置,多个消融元件形成弯曲的接触表面。 在第二预定位置,多个消融元件形成基本上直的插入构造。 至少一个铰链(27)可以连接多个消融元件(26)中的相邻的一个。 多个消融元件中的每一个可以位于壳体(29)内,壳体(29)可以具有与其一体形成的铰链的至少一部分以连接相邻的消融元件。 或者,一种超弹性材料(38),例如镍钛诺丝,可以互连消融元件。 超弹性材料可以将多个消融元件偏置到第一和第二预定位置中的至少一个中。
