Methods and devices for conduit occlusion
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, wherein the delivery system comprises a delivery device comprising an introducer shaft comprising an atraumatic tip and defining at least one opening spaced from the atraumatic tip for providing at least one catheter;
- at least one catheter, wherein a catheter comprises an end structure on a delivery end; and
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
e) occluding the fallopian tubes by forming an occlusion with the occlusive material composition within the lumen of at least one 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.

- at least one catheter, wherein a catheter comprises an end structure on a delivery end; and
-
16. A method for contraception, 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 at least one opening spaced from the atraumatic tip for providing at least one catheters; - at least one catheter, wherein a catheter comprises an end structure on a delivery end; and

- at least one catheter, wherein a catheter comprises an end structure on a delivery end; and
-
17. A transcervical device, comprising, an introducer shaft comprising an atraumatic tip and defining at least one opening spaced from the atraumatic tip for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end for maintaining the delivery end in the uterine cornua and aiding in localized delivery of a composition, and attachment elements on a proximal end.
