Techniques are described for occluding the ostium of an appendage. The first is shaped so as to define a first lateral opening when radially-expanded. More specifically, the present application relates to a rotary insert feeder that feeds inserts to a collating track on inserting or wrapping type equipment. The wave source emits electromagnetic waves into a target area of the medium, and the wave detector detects electromagnetic waves and generates output signal in response thereto. The connection elements allow the monitoring device and patch to be separately fabricated and the direct physical connection between the antenna and the monitoring device to be formed when the combination is connected to the innerliner of the tire.
