Abstract
A uterine access catheter system comprises an inner catheter and a catheter sleeve slidably disposed over the inner catheter. Initial access to the uterus is accomplished by positioning the inner catheter through the cervix with the sleeve remaining outside of the cervix. After inflating a balloon near the distal end of the inner catheter, contrast media can be injected and hysterosalpingography performed. Should the initial hysterosalpingography be unsuccessful, direct access to the fallopian tubes can be achieved by further inserting the sleeve catheter through the cervix, removing the inner catheter, and utilizing a uterine catheter and fallopian catheter for accessing the fallopian tubes.
