Abstract:
1. An apparatus for providing a restriction and sensing an associated operational parameter, the apparatus comprising: (a) an implantable restriction device configured to be secured around a portion of an anatomical structure, wherein the implantable restriction device comprises an inflatable gastric band, wherein the restriction device is operable to form a restriction within the anatomical structure, wherein the implantable restriction device presents an inner perimeter and an outer perimeter, wherein the inner perimeter is configured to engage the anatomical structure, wherein the inner perimeter has a length extending around a corresponding circumferential length of the anatomical structure, wherein the inner perimeter defines an annular recess extending around the inner perimeter, wherein the implantable restriction device has a first end and a second end, wherein the first end defines an opening, wherein the opening is configured such that the second end is insertable through the opening of the first end, wherein the second end is operable to be drawn through the opening of the first end; and (b) an implantable sensing device configured to sense a parameter associated with operation of the restriction device, wherein at least a portion of the sensing device is configured to be positioned adjacent to tissue of the anatomical structure, wherein the sensing device comprises a sensor strip and a plurality of sensors, wherein the sensors are arranged in a spaced apart relationship relative to each other along at least part of the length of the inner perimeter of the implantable restriction device, such that different sensors are simultaneously positionable at different positions along the circumferential length of the anatomical structure, wherein the plurality of sensors are arranged on the sensor strip, wherein the sensor strip has a front side and a back side, wherein at least a portion of the plurality of sensors are positioned on the front side, wherein at least a portion of the plurality of sensors are positioned on the back side, wherein the sensor strip is integrated into the annular recess.
