titleOfInvention | Intracervical contraceptive device |
abstract | An intracervical contraceptive device (ICD) is provided with an elongated, circular cylindrical stem having a hollow bore which allows the flow of fluids from the uterus. Two opposed long arms and two opposed short arms are formed at one end of the stem and extend into the uterine cavity to prevent inadvertent expulsion of the device. The long arms flair outwardly in the lateral plane of the uterine cavity while the short arms flair outwardly in a plane parallel to the anterior-posterior plane of the uterine cavity. A barrel-shaped sleeve surrounds the stem and initially conforms to the contour of the walls of the cervical canal. The sleeve is composed of a biodegradable binder material impregnated with a pharmaceutical agent which prevents spermatozoa from performing their fertilization function when the pharmaceutical agent is released into fluids passing over the sleeve. Apertures are provided in the side wall of the stem so that the pharmaceutical agent will also be released into fluids passing through the stem bore. |
