Abstract
An intrauterine device providing a membrane to cover substantially the entire surface of the uterine cavity, said device having a Y- or V-shaped resilient member with two diverging arms, a membrane covering the entire area between the diverging arms and, in addition, extending above an imaginary line passing through the terminal ends of the arms, and a flexible tail or string connected to the intersection of the arms for aiding in the removal of the device from the uterus when desired. The ends of the diverging arms have enlarged end portions and the arms are of unequal length so that the arms may be resiliently collapsed and placed in a tubular inserter with the enlarged end portions longitudinally spaced in the inserter.
