Abstract
An ovoid pessary for prevention of prolapse of the female organs through support thereof when inserted into the vaginal vault. Two elements are involved, one of body and the other a valve means, the latter having a set position for use whereby invaginate suction is effected by concavities on the body, and having a released position for withdrawal of the pessary without suction and providing means for manipulated removal. The two elements are made of soft pliable material and are readily disassembled for cleansing and re-use.
