    • A transdermally actuated gastric banding assembly is provided which includes an adjustable gastric band, a drive assembly and a transmission assembly positioned between the driver assembly and the adjustable gastric band. The drive assembly includes an internal component configured to be mounted within the body of the patient and an external component configured to operate transdermally so as to affect movement of the internal component. At least one of the internal and external components includes a magnetized member. A proximal end of the transmission assembly is connected to the internal component. A distal end of the transmission assembly is connected to a movable portion of the adjustable gastric band. In one embodiment, the internal component is mounted for rotational movement. In a further embodiment, at least one of the internal component and external component includes a plurality of magnetized members situated asymmetrically about a circumference of the at least one internal and external component.
    • 提供了经皮致动的胃束带组件,其包括可调节的胃束带,驱动组件和位于驱动器组件和可调节胃束带之间的传动组件。 驱动组件包括构造成安装在患者体内的内部部件和被配置为经皮操作以影响内部部件的运动的外部部件。 内部和外部部件中的至少一个包括磁化部件。 传动组件的近端连接到内部部件。 传动组件的远端连接到可调节的胃带的可移动部分。 在一个实施例中,安装内部部件以进行旋转运动。 在另一个实施例中,内部部件和外部部件中的至少一个包括围绕至少一个内部和外部部件的圆周非对称定位的多个磁化部件。
