Abstract

An irrigation and aspiration device includes a drive assembly, an evacuation chamber, and a delivery apparatus. The delivery apparatus includes an evacuation tube configured to hold an irrigation solution and a vacuum tube that is in fluid communication with the evacuation chamber. The drive assembly is configured to store a restoration energy within the evacuation chamber and force the irrigation solution out of the evacuation tube in response to an applied force. The device is configured to use the restoration energy to draw an aspiration fluid into the vacuum tube.

Claims

1. An irrigation and aspiration device, comprising:

an evacuation chamber;

a delivery apparatus that includes an evacuation tube configured to hold an irrigation solution and a vacuum tube in fluid communication with the evacuation chamber; and

a drive assembly configured to

store a restoration energy within the evacuation chamber and force the irrigation solution out of the evacuation tube in response to an applied force, and

use the restoration energy to draw an aspiration fluid into the vacuum tube.

2. The device of claim 1, wherein the evacuation chamber comprises a non-porous and elastically deformable chamber that defines a volume and further includes an input port, an evacuation port that is in fluid communication with the evacuation tube, and a vacuum port that is in fluid communication with the vacuum tube.

3. The device of claim 2, wherein the drive assembly is retained within the input port and movably disposed within the evacuation port and configured, in response to the applied force, to simultaneously reduce the volume of the evacuation chamber to store the restoration energy and move into a proximal end of the evacuation tube to force the irrigation fluid out of a distal end of the evacuation tube.

4. The device of claim 3, wherein the drive assembly includes a restoration apparatus, and wherein the drive assembly is configured to store at least a portion of the restoration energy within the restoration apparatus.

5. The device of claim 3, wherein the evacuation chamber is configured, in response to the restoration energy, to increase the volume to create a negative pressure that is configured to draw in the aspiration fluid through a distal end of the vacuum tube.

6. The device of claim 5, wherein the evacuation chamber comprises at least one valve configured to be in an open position when the volume is reduced and in a closed position when the volume is increased.

7. The device of claim 3, wherein the delivery apparatus comprises a nozzle that includes a delivery port and is attached to and in a fluid sealing relationship with the distal end of the evacuation tube, and wherein the nozzle is configured to divide the irrigation solution between the distal end of the evacuation tube and the delivery port into two or more circular channels to increase a velocity of and provide a circular and laminar flow of the irrigation solution out of the delivery port.

8. An irrigation and aspiration device, comprising:

an evacuation chamber that includes an input port, an evacuation port and a vacuum port;

a drive assembly in axial alignment with the input port and the evacuation port, wherein the input port and the evacuation port are separated by a distance, and wherein the drive assembly is configured to be releasably retained within the input port and movably engaged within the evacuation port;

a delivery apparatus that includes an evacuation tube configured to retain an irrigation fluid and a vacuum tube, wherein a proximal end of the evacuation tube is attached to and in a fluid sealing relationship with the evacuation port and a proximal end of the vacuum tube is attached to and in a fluid sealing relationship with the vacuum port,

wherein the drive assembly is configured to be moved in cooperation with the evacuation chamber to reduce the distance between the input port and the evacuation port to store a restoration energy and push a distal end of the drive assembly into the proximal end of the evacuation tube to force the irrigation fluid out of a distal end of the evacuation tube, and

wherein releasing the restoration energy is configured to increase the distance between the input port and the evacuation port and create a negative pressure within the evacuation chamber that is configured to draw in the aspiration fluid from a distal end of the vacuum tube.

9. The device of claim 8, wherein the evacuation chamber includes a non-porous and elastically deformable chamber that defines a volume, and wherein reducing the distance between the input port and the evacuation port comprises reducing the volume of the evacuation chamber.

10. The device of claim 9, wherein increasing the distance between the input port and the evacuation port comprises increasing the volume of the evacuation chamber.

11. The device of claim 9, wherein the evacuation chamber includes a one-way valve configured to be in an open position when the distance between the input port and the evacuation port is reduced and in a closed position when the distance between the input port and the evacuation port is increased.

12. The device of claim 8, wherein the evacuation tube is disposed within and in a coaxial relationship with the vacuum tube.

13. The device of claim 12, wherein the delivery apparatus comprises a nozzle attached to and in a fluid sealing relationship with the distal end of the evacuation tube and the distal end of the vacuum tube, wherein the nozzle includes a delivery port and is configured to divide the irrigation solution between the distal end of the evacuation tube and the delivery port into two or more circular channels to increase a velocity of and provide a circular and laminar flow of the irrigation solution out of the delivery port, wherein the nozzle includes a vacuum port that is exterior to and concentric with the delivery port, and wherein the vacuum port is configured to engage a human body orifice and provide a pathway for the aspiration fluid between the vacuum port and the distal end of the vacuum tube.

14. The device of claim 8, wherein the drive assembly includes a restoration apparatus, and wherein the drive assembly is configured to store at least a portion of the restoration energy within the restoration apparatus.

15. A method of irrigating and aspirating a nasal cavity, comprising:

providing a device that includes a drive assembly, an evacuation chamber having an input port, an evacuation port and a vacuum port, and a delivery apparatus that includes a vacuum tube and an evacuation tube configured to retain an irrigation fluid;

applying a force to move the drive assembly in cooperation with the evacuation chamber to reduce a volume of the evacuation chamber to store a restoration energy and force the irrigation fluid out of the evacuation tube, and

using the restoration energy to increase the volume of the evacuation chamber to draw in an aspiration fluid into the vacuum tube.

16. The method of claim 15, wherein moving the drive assembly in cooperation with the evacuation chamber to reduce a volume of the evacuation chamber comprises moving the drive assembly in a direction that is axial to the input port and the evacuation port to reduce a distance between the input port and the evacuation port.

17. The method of claim 16, wherein using the restoration energy to increase the volume of the evacuation chamber comprises enabling the restoration energy stored within the evacuation chamber to increase the distance between the input port and the evacuation port.

18. The method of claim 16, wherein using the restoration energy to increase the volume of the evacuation chamber comprises enabling the restoration energy stored within the drive assembly to increase the distance between the input port and the evacuation port.

19. The method of claim 15, wherein reducing a volume of the evacuation chamber comprises opening a valve to maintain a neutral pressure within the evacuation chamber, and wherein increasing the volume of the evacuation chamber comprises closing the valve to maintain a negative pressure within the evacuation chamber.

20. The method of claim 15, wherein forcing the irrigation fluid out of the evacuation tube comprises dividing the irrigation solution into two or more circular channels to increase a velocity of and provide a circular and laminar flow of the irrigation solution out of the evacuation tube.
