Methods and devices for conduit occlusion
First Claim
1. 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 an 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; and
means for providing an 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 an 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.

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.
