An apparatus for providing a restriction and sensing an associated
operational parameter, comprises a restriction device and a sensing
device. The restriction device is configured to be secured around a
portion of an anatomical structure. The restriction device is operable to
form a restriction within the anatomical structure. The sensing device is
configured to sense a parameter associated with operation of the
restriction device. At least a portion of the sensing device is
configured to be positioned adjacent to tissue of the anatomical
structure. The restriction device may comprise a gastric band, among
other things. The sensing device may comprise a pressure sensor, among
other things.
