System and method for cleansing segments of a luminal network

1. A system for instilling medium into an isolated portion of a luminal network comprising:

an extended working channel navigable to a treatment target within a patient; and

a catheter, extendible through the extended working channel and configured to transport medium to the treatment target, the catheter including:

a distal end and a proximal end;

an isolation mechanism configured to contact walls of the luminal network in order to prevent the medium and air from passing, thereby isolating a portion of the luminal network;

an inlet at the proximal end configured to receive the medium;

an outlet proximal the distal end configured to dispense the medium to the treatment target proximal the isolation mechanism; and

an air channel extending distally beyond the isolation mechanism, allowing air to bypass the isolated portion of the luminal network.

2. The system of claim 1 , wherein the isolation mechanism includes one or more inflatable balloons near the distal end of the catheter configured to inflate and contact the walls of the luminal network in order to create a barrier.

3. The system of claim 1 , wherein the isolation mechanism includes an endobronchial valve.

4. The system of claim 1 , further comprising:

a location sensor coupled to the extended working channel;

an electromagnetic field generator configured to detect the location of the location sensor as it is navigated within the luminal network;

a display capable of displaying an image of the location sensor; and

a computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to:

generate a model of the luminal network based on images of the luminal network;

identify the treatment target within the model of the luminal network; and

track the location of the location sensor while the location sensor is navigated within the luminal network.

5. The system of claim 1 , further comprising:

a medium meter configured to measure a volume of the medium as it passes the inlet.

6. The system of claim 1 , wherein the medium is one or more of an antibacterial, an antifungal, an antiviral, an immunotherapeutic solution, a fluid, an aerosol, a powder, an epoxy, and a sealant.

7. The system of claim 1 , further comprising a pressure sensor configured to determine if a portion of the luminal network has collapsed or if an internal pressure of the portion of the luminal network has exceeded a pressure threshold.

8. The system of claim 1 , further comprising:

a bag coupled to the catheter and configured to hold the medium; and

a valve configured to be toggled to between an open and a closed position to allow flow of the medium to and from the bag.

9. The system of claim 1 , further comprising:

at least one of a pump or a syringe configured to push the medium through the inlet and out the outlet to the treatment target and to withdraw the medium from the treatment target.

10. The system of claim 1 , further comprising a shaft extending distally beyond the distal end of the catheter, the shaft including an aperture configured to provide suction during or after dispensing of the medium from the outlet, such that the outlet and the aperture form a defined flow path for the medium to flow from the outlet to the aperture.

11. A catheter for instilling medium into a portion of a luminal network, the catheter comprising:

a distal end and a proximal end;

an isolation mechanism configured to contact walls of the luminal network to isolate a portion of the luminal network;

an inlet at the proximal end configured to receive the medium;

an outlet near the distal end configured to dispense the medium to a treatment target proximal the isolation mechanism; and

an air channel extending distally beyond the isolation mechanism and configured to allow air to bypass the isolated portion of the luminal network.

12. The catheter of claim 11 , wherein the isolation mechanism includes one or more inflatable balloons near the distal end of the catheter configured to inflate and contact the walls of the luminal network to create a barrier.

13. The catheter of claim 11 , wherein the isolation mechanism includes an endobronchial valve.

14. The catheter of claim 11 , further comprising:

a location sensor coupled to the catheter;

an electromagnetic field generator configured to detect the location of the location sensor as it is navigated within the luminal network;

a display capable of displaying an image of the location sensor; and

a computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to:

generate a model of the luminal network based on images of the luminal network;

identify the treatment target within the model of the luminal network; and

track the location of the location sensor while the location sensor is navigated within the luminal network.

15. The catheter of claim 11 , further comprising a medium meter configured to measure a volume of the medium as it passes the inlet.

16. The catheter of claim 11 , wherein the medium is one or more of an antibacterial, an antifungal, an antiviral, an immunotherapeutic solution, a fluid, an aerosol, a powder, an epoxy, and a sealant.

17. The catheter of claim 11 , further comprising a pressure sensor configured to determine if a portion of the luminal network has collapsed or if an internal pressure of the portion of the luminal network has exceeded a pressure threshold.

18. The catheter of claim 11 , further comprising:

a bag coupled to the catheter and configured to hold the medium; and

a valve configured to be toggled between an open position and a closed position to allow the medium to flow to and from the bag.

19. The catheter of claim 11 , further comprising:

at least one of a syringe or a pump configured to push the medium through the inlet and out the outlet to the treatment target and to withdraw the medium from the treatment target.

20. The catheter of claim 11 , further comprising a shaft extending distally beyond the distal end of the catheter, the shaft including an aperture configured to provide suction during or after dispensing of the medium from the outlet, such that the outlet and the aperture form a defined flow path for the medium to flow from the outlet to the aperture.
