Abstract

The present invention comprises systems, methods and devices for the delivery of visualizable or treatment compositions or therapeutic agents comprising device elements for diagnosis and/or treatment of conduits. A delivery system comprising an introducer shaft having at least one exit port and at least one delivery catheter for placement of compositions into the conduit, such as a fallopian tube.

Claims

1. A method of diagnosis, comprising,

a) providing a visualizable composition to at least a portion of one or two fallopian tubes of a human or animal by a delivery system that delivers an effective amount of the visualizable composition, wherein the delivery system comprises a delivery device comprising at least an introducer shaft comprising an atraumatic tip for positioning the tip at the uterine fundus and one or two exit ports for providing at one or two catheters;

one or two catheters, wherein each of the one or two catheters comprises an end structure on a delivery end that maintains the delivery end in an uterine cornua and aids in localized delivery of the visualizable composition, elements for providing the visualizable composition into and through the one or two catheters; and

a visualizable composition; and

b) subjecting the human or animal to a visualization procedure; and

c) determining where the visualizable fluid flows.

2. The method of claim 1, wherein the visualizable composition is provided to at least a portion of one fallopian tube, wherein the delivery device has one exit port and one catheter, and wherein the visualizable composition is provided into and through the one catheter.

3. The method of claim 1, wherein a visualizable composition is provided to at least a portion of two fallopian tubes, wherein the delivery device has two exit ports and two catheters, and wherein the treatment composition is provided into and through the two catheters.

4. The method of claim 1, further comprising providing a visualizable composition to the uterus.

5. The method of claim 2, further comprising providing a visualizable composition to the uterus.

6. The method of claim 3, further comprising providing a visualizable composition to the uterus.

7. The method of claim 1, wherein the visualizable composition is contrast medium.

8. The method of claim 7, wherein the contrast medium is sonolucent substances, radiopaque substances, iodine based contrast media, urografin, omnipaque, diatrizoate, metrizoate, ioxaglate iopamidol, iohexol, ioxilan, iopromide and iodixanol, non-iodine based contrast media, barium sulfate, gadolinium, ionic or non-ionic contrast material, gas/liquid phase contrast media, air in saline, frothed compositions, compositions comprising metals, paramagnetic materials, high atomic number non-metal materials, radioisotopes, gases or gas precursors, chromatophores, fluorophores, electrical impedence materials or combinations thereof.

9. The method of claim 1, wherein the visualization procedure is sonography, ultrasound, fluoroscopy, radiography, nuclear medicine techniques, magnetic resonance techniques or combinations thereof.

10. The method of claim 1, further comprising a delivery device stabilizer for holding the delivery device in place once the device is positioned.
