    • Various methods and devices are provided for aligning an internal antenna with an external device. In one embodiment, an implantable restriction system is provided and includes an implantable restriction device configured to form a restriction in a pathway, and an implantable housing associated with the implantable restriction device. The housing has at least one antenna that can be configured to communicate telemetrically with a transceiver regardless of a rotational orientation of the housing about an axis. The at least one antenna can extend along an axis aligned with the longitudinal axis of a catheter extending from the housing. In one embodiment, the implantable housing can contain a sensor that can be configured, for example, to measure at least one of a system parameter and a physiological parameter, and the antenna can be effective to communicate the measured parameter to the transceiver.
    • 提供了用于将内部天线与外部设备对准的各种方法和装置。 在一个实施例中,提供可植入的限制系统,并且包括被配置为在通路中形成限制的可植入的限制装置,以及与所述可植入的限制装置相关联的可植入的壳体。 壳体具有至少一个天线,其可以被配置为与收发器遥测地通信,而不管壳体绕轴线的旋转取向如何。 至少一个天线可以沿着与从壳体延伸的导管的纵向轴线对准的轴线延伸。 在一个实施例中,可植入外壳可以包含传感器,其可以被配置为例如测量系统参数和生理参数中的至少一个,并且天线可以有效地将测量的参数传送到收发器。
