An anatomic vaginal occluder is constructed of soft, relatively compliant materials for atraumatic insertion through the vaginal opening. This device integrates at its distal end a horizontally oriented, elliptically shaped, occlusive prominence coupled with a larger vertically oriented, elliptical occlusive prominence, located more proximally on the devices longitudinal axis. The vaginal wall tissue is compressed radially and put under longitudinal tension completely circumferentially around the occlusive features to create a seal against gas loss.
