Abstract

Fluid communication may be improved for an ethmoid sinus by installing a port or wick in the wall of the ethmoid sinus to provide a fluid passageway across the wall of the ethmoid sinus. Fluid communication for an ethmoid sinus may also be improved by inflating a balloon in a retrobullar space, remodeling the posterior wall of the ethmoid bulla to expand the transition area in the retrobullar space. In addition, a wall defining the retrobullar space may be pierced to provide a passageway for fluid communication.

Claims

1. A method of treating a sinus cavity, the method comprising

(a) piercing at least one wall of the sinus cavity to form an opening, wherein the act of piercing at least one wall of the sinus cavity comprises:

(i) piercing the sinus cavity in a first wall location, and

(ii) piercing the sinus cavity in a second wall location;

(b) inserting a fluid transfer member through the opening in the at least one wall of the sinus cavity, wherein the fluid transfer member comprises a first port, a second port, and a wick defining a fluid passageway and wherein the fluid transfer member is configured to provide a direct fluid communication path between the interior of the sinus cavity and a region external to the sinus cavity, wherein a portion of fluid transfer member extends into the interior of the sinus cavity, wherein the portion of the at least one fluid transfer member extending into the interior of the sinus cavity is longer than a portion disposed in the opening of the sinus cavity, wherein the wick is configured to transfer fluid medication through a capillary action and to administer the fluid medication directly from the wick to mucosa in the sinus cavity, wherein the act of inserting the fluid transfer member comprises;

(i) inserting the first port into the first wall location, and

(ii) inserting the second port into the second wall location so that the first port and the second port are in direct fluid communication with one another via the wick; and

(c) administering the fluid medication into a nostril in such a way that the fluid medication travels along the fluid transfer member by way of a capillary action, and is administered directly from the wick to mucosa in the sinus cavity by the wick extending into the interior of the sinus cavity.

2. The method of claim 1, wherein the sinus cavity comprises an ethmoid sinus cell.

3. The method of claim 2, wherein the sinus cavity comprises an ethmoid bulla.

4. The method of claim 1, wherein the first wall location provides a path to an anterior space within the paranasal cavity, wherein the second wall location provides a path to an adjacent sinus cavity.

5. The method of claim 1, wherein the first port has at least one outwardly extending retention feature configured to engage a wall of the sinus cavity.

6. The method of claim 1, wherein the fluid transfer member comprises a bioabsorbable material.

7. The method of claim 1 comprising the step of creating a passageway in an ethmoid sinus, by:

(a) positioning a piercing element adjacent to the middle turbinate vertical basal lamella; and

(b) piercing the middle turbinate vertical basal lamella, wherein the act of piercing the middle turbinate vertical basal lamella comprises driving the piercing element into the middle turbinate vertical basal lamella, thereby creating a passageway in the posterior wall of the middle turbinate vertical basal lamella.

8. A method of treating a sinus cavity, the method comprising

(a) piercing two walls of the sinus cavity to form an opening in both walls;

(b) inserting a fluid transfer member through the opening in the two walls of the sinus cavity, wherein the fluid transfer member comprises a first port, a second port, and a wick defining a fluid passageway and wherein the fluid transfer member is configured to provide a direct fluid communication path between the interior of the sinus cavity and a region external to the sinus cavity, wherein the wick extends into the interior of the sinus cavity, wherein the first port is disposed in the opening of a first wall of the two walls, wherein the second port is disposed in the opening of a second wall of the two walls, wherein the wick provides direct fluid communication between the first port and the second port, wherein a portion of the fluid transfer member extending into the interior of the sinus cavity is longer than a portion disposed in the opening of the sinus cavity, wherein the wick is configured to transfer fluid medication through a capillary action and to administer the fluid medication directly from the wick to mucosa in the sinus cavity; and

(c) administering the fluid medication into a nostril in such a way that the fluid medication travels along the fluid transfer member by way of a capillary action, and is administered directly from the wick to mucosa in the sinus cavity by the fluid transfer member extending into the interior of the sinus cavity.
