First Claim
1. A method for occluding at least one fallopian tube in a human or animal body, comprising,a) providing a delivery system that delivers an effective amount of an occlusive material composition the delivery system comprising a delivery device comprising an introducer shaft comprising a closed tip and defining at least one opening spaced from the closed tip for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end an occlusive material composition and means for providing the occlusive material composition into and through at least one catheter;
b) positioning the closed 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 at least one 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 the catheter to at least one tubal ostium and a portion of its fallopian tube an effective amount of the occlusive material composition to effect occlusion of at least one fallopian tube.

Abstract
The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of means for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable material that supports tissue ingrowth that eventually replaces the material leaving little or no original material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.
