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.

Claims

1. A method for opening the lumen of at least one occluded fallopian tube, comprising,

a) providing a delivery system comprising a delivery device comprising at least 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, and one or more elements for opening a conduit,

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 the 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 localizing the one or more elements for opening a conduit at an occlusion in the lumen of at least one fallopian tube;

d) activating the one or more elements for opening a conduit at the occlusion in the lumen of the at least one fallopian tube; and

e) opening the lumen of the at least one fallopian tube.

2. The method of claim 1, wherein the one or more elements for opening the conduit comprise devices or members for providing shockwaves to shatter the occluding material.

3. The method of claim 1, further comprising

f) maintaining the opening of the lumen of the at least one fallopian tube by providing a stent within the lumen of the at least one fallopian tube.

4. The method of claim 1, wherein the one or more elements for opening the conduit comprise chemical elements.

5. The method of claim 1, wherein the one or more elements for opening the conduit comprise biological elements.

6. The method of claim 1, wherein the one or more elements for opening the conduit comprise mechanical elements.

7. A method for opening the lumen of one occluded fallopian tube, comprising,

a) providing a delivery system comprising a delivery device comprising an introducer shaft comprising a closed tip and defining an opening spaced from the closed tip for providing a catheter;

one catheter comprising an end structure on a delivery end, and one or more elements for opening a conduit,

b) positioning the closed tip of the introducer shaft at or near the fundus of a uterus,

c) positioning the delivery end of the catheter at or near the 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 localizing the one or more elements for opening a conduit at an occlusion in the lumen of a fallopian tube;

d) activating the one or more elements for opening a conduit at an occlusion in the lumen of the fallopian tube; and

e) opening the lumen of the fallopian tube.

8. The method of claim 7, wherein the one or more elements for opening the conduit comprise devices or members for providing shockwaves to shatter the occluding material.

9. The method of claim 7, further comprising

f) maintaining the opening of the lumen of the fallopian tube by providing a stent within the lumen of the fallopian tube.

10. The method of claim 7, wherein the one or more elements for opening the conduit comprise chemical elements.

11. The method of claim 7, wherein the one or more elements for opening the conduit comprise biological elements.

12. The method of claim 7, wherein the one or more elements for opening the conduit comprise mechanical elements.

13. A method for opening the lumens of two occluded fallopian tubes, comprising,

a) providing a delivery system comprising a delivery device comprising an introducer shaft comprising a closed tip and defining two openings spaced from the closed tip, each opening for providing a catheter;

two catheters each comprising an end structure on a delivery end, and one or more elements for opening a conduit,

b) positioning the closed tip of the introducer shaft at or near the fundus of a uterus,

c) positioning the delivery end of each catheter at or near the 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 localizing the one or more elements for opening a conduit at an occlusion in the lumen of a fallopian tube;

d) activating the one or more elements for opening a conduit at occlusion in the lumen of the fallopian tube; and

e) opening the lumen of the fallopian tube.

14. The method of claim 13, wherein the elements for opening the conduit comprise devices or members for providing shockwaves to shatter the occluding material.

15. The method of claim 13, further comprising

f) maintaining the opening of the lumen of the fallopian tube by providing a stent within the lumen of the fallopian tube.

16. The method of claim 13, wherein the one or more elements for opening the conduit comprise chemical elements.

17. The method of claim 13, wherein the one or more elements for opening the conduit comprise biological elements.

18. The method of claim 13, wherein the one or more elements for opening the conduit comprise mechanical elements.
