Methods and devices for conduit occlusion
First Claim
1. A method for occluding 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, wherein the delivery system comprises a delivery device comprising an introducer shaft comprising an atraumatic tip and defining one opening spaced from the atraumatic tip for providing a catheter;
- one catheter, wherein the catheter comprises an end structure on a delivery end, and means for providing an occlusive material composition into and through the catheter; and
an occlusive material composition;
(b) positioning the atraumatic tip of the introducer shaft at or near the fundus of a uterus;
(c) positioning the delivery end of the 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 the catheter an effective amount of the occlusive material composition at or near the ostia of the fallopian tubes; and
(e) occluding one fallopian tube by forming an occlusion with the occlusive material composition within the lumen of the fallopian tube.

Abstract
The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of elements for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable or degradable material that supports tissue ingrowth or wound healing or a similar response that replaces the cured occlusive material leaving little or no original occlusive 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.
