Abstract: Non-adhesive medical attachment articles include a first rotationally distinct segment (110), where the first rotational segment has a circular or semi-circular array of angled microneedles (111), and a second rotationally distinct segment, (120) with a second sequential circular or semi-circular array of angled microneedles (121). A communication member (130) connects the two rotationally distinct segments. The arrays of microneedles are angled in opposite directions, and the segments rotate in opposite directions.
