    • An electrode catheter (2) includes a handle (4) to which a catheter shaft (6) is mounted. The catheter shaft has a distal end (10) carrying plurality of electrodes (12). Dual purpose wires (18) extend from an electrical connector (14) on the handle, through separate axial lumens (16) in the catheter shaft and to the electrodes. The dual purpose wires are physically secured at their distal and proximal ends to the distal end of the catheter shaft and to the handle, respectively, so that rotation of the handle causes a rotational torque to be transmitted through the dual purpose wires to the distal end of the catheter shaft. Each dual purpose wire has an electrical resistance of no greater than about 0.80 ohms per centimeter and a torsional stiffness of at least about 0.25 to 1.0 inch-ounce (17654 to 70616 dyne-cm) for each 110 cm length of catheter shaft when the proximal end of the catheter shaft is rotated 3 turns. This construction provides a simply constructed, low cost torquing electrode catheter.
    • 电极导管(2)包括一个手柄(4),安装有导管轴(6)。 导管轴具有承载多个电极(12)的远端(10)。 双用途线(18)从手柄上的电连接器(14)延伸通过导管轴中的分离的轴向腔(16)和电极。 双用途导线在其远端和近端处分别物理地固定到导管轴的远端和手柄,使得手柄的旋转使得旋转扭矩通过双用途导线传递到远端 的导管轴。 每个双用途导线对于每个110cm长的导管轴具有不大于约0.80欧姆/厘米的电阻和至少约0.25至1.0英寸盎司(17654至70616达因厘米)的扭转刚度,当近端 导管轴末端旋转3圈。 这种结构提供了简单构造的低成本扭转电极导管。

    • A suture lock to be used with a suture thread. The suture lock comprises at least one passageway for receiving a suture thread, with the passageway having at least a portion of its length having a longitudinal side opening arranged to slidably receive the suture. The passageway is tapered inwardly and including an interior surface having inwardly converging teeth. The invention may also comprise a suture lock having an adjustable channel located within the suture lock. The channel may be adjusted between an open and a closed position, thereby allowing the suture to be secured. Translation of the suture itself may be utilized to adjust the positioning of the channel. The suture lock may contain a releasable device to retain the channel in multiple positions between the closed and open position.
    • 缝合线用于缝合线。 缝线锁包括用于接纳缝合线的至少一个通道,通道具有其长度的至少一部分具有布置成可滑动地容纳缝合线的纵向侧开口。 通道向内逐渐变细并且包括具有向内收敛的牙齿的内表面。 本发明还可以包括具有位于缝线锁内的可调节通道的缝合线锁。 通道可以在打开位置和闭合位置之间进行调节,从而允许缝合线固定。 可以利用缝合线本身的翻译来调节通道的定位。 缝线锁可以包含可释放装置,以将通道保持在闭合位置和打开位置之间的多个位置。
