A method for occluding two fallopian tubes in a human or animal body, comprising, a) providing a delivery system that delivers an effective amount of an occlusive material composition, wherein the delivery system comprises a delivery device comprising an introducer shaft comprising a atraumatic tip and defining two openings spaced from the atraumatic tip for providing two catheters; two catheters, wherein each catheter comprises an end structure on a delivery end; an occlusive material composition, and means for providing the occlusive material composition into and through the two catheters; b) positioning the atraumatic tip of the introducer shaft at or near the fundus of a uterus; c) positioning the delivery end of each of the catheters at or near a uterine cornua such that each of the end structures 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 each cathether an effective amount of the occlusive material composition at or near the ostia of the fallopian tubes; and e) occluding the fallopian tubes by forming an occlusion with the occlusive material composition within the lumen of each fallopian tube.
