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.

First claim

What is claimed is:

1. A transcervical device, comprising, an introducer shaft comprising an atraumatic tip and defining one opening proximate the atraumatic tip for providing one catheter; the 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, attachment elements on a proximal end, and elements for providing the composition into and through the catheter.

2. The transcervical device of claim 1 , wherein the end structure is a cup, nozzle, or a balloon.

3. The transcervical device of claim 1 , further comprising a delivery device stabilizer for holding the transcervical device in place once positioned.

4. The transcervical device of claim 3 , wherein the delivery device stabilizer fits over and attaches to the cervix of the patient or fits into or expands within the cervix to hold the device in position.

5. The transcervical device of claim 1 , wherein the catheter is a dual lumen balloon catheter.

6. The transcervical device of claim 1 , further comprising a composition comprising an occlusive material.

7. A transcervial device, comprising,
an introducer shaft having a closed tip for contacting the fundus of a uterus and having one exit port proximate the closed tip for providing one catheter; and
one catheter, comprising at the delivery end an end structure that aids in localized delivery of a composition to the tubal ostia of a fallopian tube, wherein the end structure is a cup, nozzle, or balloon.

8. The transcervical device of claim 7 , further comprising means for providing the composition into and through the catheter.

9. The transcervical device of claim 7 , further comprising a delivery device stabilizer for holding the transcervical device in place once positioned.

10. The transcervical device of claim 9 , wherein the delivery device stabilizer fits over or attaches to the cervix of the patient or fits into or expands within the cervix to hold the device in position.

11. The transcervical device of claim 7 , wherein the catheter is a dual lumen balloon catheter.

12. The transcervical device of claim 7 , further comprising a composition comprising an occlusive material.
