An intravaginal device has an insertion end, a withdrawal end, a longitudinal axis, and a device interior, and it includes a first structural material formed into a device frame and a second cushioning material having a thickness surrounding portions of the device frame. The first structural material includes a working portion disposed proximate the withdrawal end and an anchoring portion extending therefrom disposed proximate the insertion end. The device frame includes interconnected elongate elements having a maximum cross-section of less than about 5 mm and a longitudinal axis. The device frame has a plurality of primary bearing surfaces arranged and configured to bear on vaginal tissue during insertion and use, and the thickness of the cushioning material on the device frame is greater on the primary bearing surfaces than on surfaces of the device frame disposed toward the device interior. The device further includes a withdrawal element operatively connected to the working portion. Preferably, the first structural material is a high modulus polymer and the second material is a thermoplastic elastomer. The intravaginal device may be included in a device delivery system including a delivery applicator. |
