Abstract

Systems, devices, and methods for imaging a sinus in a patient involving a through sinus are presented. In one instance, a system includes a radiopaque wound filler for disposing into the through sinus. The system further includes a radiopaque solution for deploying into the sinus, and a radiopaque solution unit having a radiopaque solution reservoir and a positive pressure source. Other systems, devices, and methods are presented.

Claims (32)

1. A system for imaging a sinus in a patient involving a through sinus, the system comprising:

a radiopaque wound filler for disposing into the through sinus, the radiopaque wound filler comprising a porous material and a first radiopaque marker configured to present a first contrast on a radiographic image;

a radiopaque solution for deploying into the sinus, the radiopaque solution comprising a second radiopaque marker configured to present a second contrast on a radiographic image, the second contrast being distinct from the first contrast; and

a reduced pressure source configured to be coupled in fluid communication with the sinus.

2. The system of claim 1 , wherein the first radiopaque marker comprises a spaced metallic material.

3. The system of claim 1 , wherein the first radiopaque marker comprises a spaced graphene material.

4. The system of claim 1 , wherein the reduced pressure source is fluidly coupled to a collection reservoir.

5. A system for imaging a sinus in a patient involving a through sinus, the system comprising:

a radiopaque foaming unit configured to generate a radiopaque foam and to be in fluid communication with the sinus through a conduit, wherein the radiopaque foam is at least initially flowable through the conduit to the sinus; and

a reduced pressure unit configured to be fluidly coupled to the sinus, the reduced pressure unit comprising a reduced pressure source and a collection reservoir, the reduced pressure source for supplying reduced pressure to the sinus, and the collection reservoir for receiving fluids from the sinus.

6. The system of claim 5 , wherein the radiopaque foaming unit comprises:

a first fluid source containing a first fluid;

a second fluid source containing a second fluid;

a radiopaque solution source containing a radiopaque solution;

a mixing area fluidly coupled to the first fluid source, the second fluid source, and the radiopaque solution source; and

wherein the radiopaque foaming unit is operable to produce the radiopaque foam when the first fluid, the second fluid, and the radiopaque solution are mixed.

7. The system of claim 5 , wherein the radiopaque foaming unit comprises a first fluid source containing a radiopaque, foamable solution and an agitator.

8. The system of claim 5 , wherein the radiopaque foaming unit comprises a first fluid source containing a radiopaque, foamable solution and a gas injector for causing the radiopaque, foamable solution to foam.

9. The system of claim 1 , wherein the radiopaque wound filler comprises a foam.

10. The system of claim 1 , wherein the radiopaque wound filler comprises a sintered polymer.

11. The system of claim 1 , further comprising a radiopaque solution unit for fluidly coupling to the sinus, the radiopaque solution unit comprising a radiopaque solution reservoir and a positive pressure source, the radiopaque solution reservoir configured to receive the radiopaque solution.

12. The system of claim 1 , wherein the first radiopaque marker is embedded within the radiopaque wound filler.

13. The system of claim 1 , wherein the first radiopaque marker is a coating applied to the radiopaque wound filler.

14. The system of claim 11 , the radiopaque solution reservoir being in fluid communication with the positive pressure source.

15. A kit for imaging a sinus in a patient involving a through sinus, the kit comprising:

a radiopaque wound filler for disposing into the through sinus;

wherein the radiopaque wound filler comprises a porous material having patterned radiopaque markers that are operable to present a patterned radiographic image; and

a radiopaque solution for deploying into the sinus and operable, when subjected to radiography, to make a radiographic image different from the patterned radiographic image of the wound filler.

16. The kit of claim 15 , further comprising a package for securing the radiopaque wound filler and the radiopaque solution.

17. A kit for imaging a sinus in a patient involving a through sinus, the kit comprising:

a radiopaque wound filler for disposing into the through sinus, the radiopaque wound filler comprising a porous material having patterned radiopaque markers operable to present a patterned radiographic image, the patterned radiopaque markers comprising a coating applied to the radiopaque wound filler; and

a radiopaque solution for deploying into the sinus and operable, when subjected to radiography, to make a radiographic image different from the patterned radiographic image of the wound filler.
