    • A magnetically guided catheter (210) with sensor (256) provides a permanent magnet (34), and a sensor, both in the distal end portion of the catheter. The sensor is responsive to the presence of a magnetic field of predetermined strength supplied by an external magnet. The external magnet forms a magnetic coupling with the catheter magnet to permit manipulation of the catheter in response to movement of the external magnet. The sensor responds to the magnetic field of the external magnet, but only when the external magnet, and the catheter magnet are magnetically coupled sufficiently to create a traction force so that the catheter distal end portion can be manipulated by the movement of the external magnet. The apparatus for creating a magnetic guidance path for a remote device includes a follower magnet (12), a sensor, both of which are attached to the remote device, and a leader magnet (34). The leader magnet forms a magnetic guidance path by permeating the location of the remote device to form a magnetic coupling between the leader magnet, and the follower magnet. The sensor responds to the magnetic field provided by the leader magnet only when the leader magnet, and the follower magnet are magnetically coupled sufficiently to permit manipulation of the follower magnet by movement of the leader magnet.
    • 具有传感器(256)的导磁导管(210)在导管的远端部分提供永磁体(34)和传感器。 传感器响应于由外部磁体提供的预定强度的磁场的存在。 外部磁体与导管磁体形成磁耦合,以允许响应于外部磁体的移动来操纵导管。 传感器响应于外部磁体的磁场,但是仅当外部磁体和导管磁体被磁耦合到足以产生牵引力时,才能通过外部磁体的移动来操纵导管远端部分。 用于产生用于远程装置的磁引导路径的装置包括从动磁体(12),传感器(两者都附接到远程装置)和引导磁体(34)。 引导磁体通过渗透远程设备的位置形成磁性引导路径,以在引导磁体和从动磁体之间形成磁耦合。 只有当引导磁体和从动磁体被磁耦合到足以允许从动磁体通过引导磁体的移动来操纵从动磁体时,传感器仅响应于引导磁体提供的磁场。

    • Magnetic switch arrangement including a first magnetic system (24), a second magnetic system (25) and a magnetic switching element (18). The first magnetic system (24) is arranged for biasing the magnetic switching element (18) and the second magnetic system (25) is arranged to interact with the biasing magnetic field from the first magnetic system at the magnetic switching element so that the magnetic switching element is in a predefined state. The first magnetic system (24) also includes a magnetic field assembler (19) arranged for creating a longitudinal magnetic field inside the assembler. An advantage of the invention being to provide a magnetic switch arrangement which compensates for the angular sensitivity of the switching element.
    • 磁开关装置包括第一磁系统(24),第二磁系统(25)和磁开关元件(18)。 第一磁性系统(24)布置成偏置磁性开关元件(18),并且第二磁性系统(25)被布置成与磁性开关元件处的来自第一磁性系统的偏置磁场相互作用,使得磁性开关 元素处于预定义状态。 第一磁性系统(24)还包括磁场组装器(19),其布置成用于在组装器内产生纵向磁场。 本发明的一个优点是提供补偿开关元件的角度灵敏度的磁开关装置。
