Abstract
The present invention is directed to methods and apparatus for artificially transporting an egg from an ovary to the uterus in a patient having dysfunctional natural fallopian tubes. A preferred embodiment of the apparatus of the present invention includes an ovisac in which one of the patient's ovaries is encapsulated in order to collect any ova discharged. A plurality of fluid supply tubes serve to wash the ova toward a tubular member that is secured in communication with the uterine cavity. In one embodiment, a reservoir of fluid and a programmable micropump are provided, both of which are adapted to be implanted in the patient. The method of the present invention advantageously comprises the initial step of charging the artificial fallopian tube with a solution of nutrients and sperm immediately prior to ovulation. After fertilization has had an opportunity to occur, nutrient solution is introduced into the fallopian tube in a continuous, but pulsatile manner at a rate that will cause the ovum to be ejected into the uterine cavity about two to three days after ovulation.
