Abstract: An implantable restriction system having an antenna capable of being readily and predictably movable to achieve a desired orientation that is effective to communicate with an external device is provided. The antenna can be movably coupled to a housing such that the antenna can float and/or move freely with respect to the housing. The housing can be part of a gimbal element or another component of the system. The antenna can include a weight or a magnetic element to help it achieve the desired orientation. Methods for transcutaneously communicating with an implantable restriction device are also provided.

Abstract: Various methods and devices are provided for reorienting an implantable port. In one embodiment, an implantable port is provided and includes a base adapted to be anchored to tissue, and a housing pivotally mounted on the base and having a septum formed therein and adapted to receive fluid and to provide access to a fluid reservoir formed within the housing. In an exemplary embodiment, the housing can be pivotally mounted to the base using a ball and socket joint. For example, at least one of a distal surface of the housing and a proximal surface of the base is convex, and the other one of the distal surface of the housing and the proximal surface of the base is concave.

Abstract: Methods and devices are provided for regulating a hydraulic restriction system including a restriction device. In general, the methods and devices can allow for non-invasive, transient pressure control. The methods and devices can also, in some embodiments, mechanically regulate pressure of the restriction device without using any electrical components that may need to be powered to operate over extended periods of time.

Abstract: Methods and devices are provided for regulating a restriction system. In one exemplary embodiment, a restriction system is provided having a restriction device configured to receive fluid and to form a restriction in a pathway corresponding to an amount of fluid contained therein, at least one fluid reservoir, and a fluid logic system coupled between the restriction device and the at least one fluid reservoir. The fluid logic system is configured to regulate an amount of fluid in the restriction device in response to a fluid pressure acting thereon.
