    means for providing an occlusive material composition into and through the at least one catheter;

    b) positioning the atraumatic tip of the introducer shaft at or near the fundus of a uterus;

    c) positioning the delivery end of at least one catheter at or near a uterine cornua such that the end structure is at or near a tubal ostium, wherein the end structure maintains the delivery end in the uterine cornua and aids in localized delivery of the occlusive material composition;

    d) delivering from a catheter an effective amount of an occlusive material composition at or near the ostia of the fallopian tubes; and
