Abstract

An apparatus comprises an absorbent body, a non-permeable feature, and a port feature. The absorbent body comprises a wicking feature. The non-permeable feature is coupled with the absorbent body. The non-permeable feature and at least a portion of the absorbent body are configured to fit in an opening in a paranasal sinus wall. The port feature extends through the absorbent body. The port feature defines a lumen. The wicking feature extends outwardly relative to the port lumen. During installation of the apparatus, the non-permeable feature is positioned in an opening in the paranasal sinus wall. The absorbent body is oriented such that the wicking feature is in contact with mucosal tissue in a sinus cavity defined by the paranasal sinus wall. A proximal portion of the absorbent body is positioned outside the paranasal sinus wall.

First claim

We claim:

1. A sinus wall implant comprising:
(a) a cylindraceous body defining a longitudinal axis and a lumen;
(b) a flange extending from a first side of the cylindraceous body, wherein the flange is resiliently biased to extend along a plane perpendicular to the longitudinal axis of the cylindraceous body;
(c) a retention wing extending from a second side of the cylindraceous body; and
(d) a release element extending from the retention wing through the lumen.

2. The sinus wall implant of claim 1 , wherein the retention wing comprises a living hinge, wherein the living hinge connects the retention wing to the cylindraceous body.

3. The sinus wall implant of claim 2 , wherein the retention wing comprises a strut, wherein the living hinge connects the strut to the cylindraceous body.

4. The sinus wall implant of claim 3 , wherein the strut comprises a strut wall having a width, wherein the living hinge comprises a hinge wall having a width, wherein the width of the strut wall is greater than the width of the hinge wall.

5. The sinus wall implant of claim 3 , wherein the strut has a flexural modulus, wherein the living hinge has a flexural modulus, wherein the flexural modulus of the strut is greater than the flexural modulus of the living hinge.

6. The sinus wall implant of claim 1 , wherein the flange is configured to abut a sinus wall within a nasal cavity of a patient.

7. The sinus wall implant of claim 6 , wherein the retention wing is configured to abut a sinus wall within a sinus cavity of the patient.

8. The sinus wall implant of claim 7 , wherein the retention wing is disposed at a distal end of the cylindraceous body, wherein the flange is disposed at a proximal end of the cylindraceous body, and wherein the release element extends proximal to the flange.

9. The sinus wall implant of claim 7 , wherein the flange comprises a first side and an opposed second side, wherein the release element extends from the first side to the second side and parallel to the longitudinal axis.

10. The sinus wall implant of claim 7 , wherein the sinus wall implant is operable to transition between a first position and a second position, wherein the retention wing comprises a strut, wherein the release element and the strut are perpendicular in the first position, wherein the release element and the strut are parallel in the second position.

11. The sinus wall implant of claim 1 , wherein the flange is annular.

12. The singular wall implant of claim 1 , wherein the singular wall implant is formed from a non-bioresorbable material.

13. The singular wall implant of claim 1 , wherein the singular wall implant is formed from a bioresorbable material.

14. A method of treating a patient using a sinus wall implant, wherein the sinus wall implant comprises a cylindraceous body defining a longitudinal axis, defining a lumen through the longitudinal axis, a flange extending from a first side of the cylindraceous body, and a pair of retention wings extending from a second side of the cylindraceous body, and a release element extending from the retention wings and through the lumen the method comprising:
(a) locating an opening formed in a sinus wall, wherein the opening extends between a nasal cavity and a sinus cavity;
(b) passing the pair of retention wings from the nasal cavity through the opening to the sinus cavity;
(c) abutting the pair of retention wings with the sinus wall after the pair of retention wings pass through the opening;
(d) positioning the flange in the nasal cavity;
(e) abutting the flange with the sinus wall; and
(f) disposing the release element in the opening when the retention wings are disposed in the sinus cavity.

15. The method of claim 14 , further comprising pulling the release element through the opening and into the nasal cavity to remove the pair of retention wings from the sinus cavity.

16. The method of claim 15 , further comprising rotating each retention wing in the pair of retention wings about a living hinge in response to pulling the release element.

17. The method of claim 14 , further comprising orienting the pair of retention wings parallel to the longitudinal axis to pass the retention wings pass through the opening.

18. An apparatus for placement within a sinus wall, the apparatus comprising:
(a) a cylindraceous body defining a longitudinal axis and a lumen extending along the longitudinal axis;
(b) a flange;
(c) a retention wing, wherein the retention wing is configured to rotate between a first position and a second position, wherein the retention wing is parallel to the longitudinal axis in the first position, wherein the retention wing is perpendicular to the longitudinal axis in the second position; and
(d) a release element, wherein the release element that extends from the retention wings and is configured to be disposed in the lumen when the retention wing is in the second position.

19. The apparatus of claim 18 , further comprising a living hinge connecting the retention wing to the cylindraceous body.

20. The apparatus of claim 18 , further comprising a retention element disposed in the lumen and extending from the retention wing.
