Abstract
Abstract An intravaginal anchoring device for mammalian females comprises an elongated tubular body provided with a plurality of slots disposed substantially parallel to each other and to the length of the tubular body such that, in an expanded position, the ends of the body are moved towards each other and flange portions of the body between adjacent pairs of slots are distended away from an axis of the body and, in a collapsed position, the ends of the body are moved away from each other and the flange portions are retracted towards the axis. The device further comprises a biasing means for urging the body into the expanded position. A purpose of the anchor is to contain any payload appropriate to the interior of a female mammal's vagina.
