Abstract

A nasal spray delivery guide including a pair of guide elements spaced apart from one another and configured to be at least partially inserted into respective nostrils of a patient, and a flexible connector element attached to and extending between the guide elements. Each guide element includes an aperture extending therethrough from a base end to a tip end of the guide element. A method for delivering a nasal spray into a patient's nose includes the steps of providing the nasal spray delivery guide, inserting the guide elements at least partially into respective nostrils of the patient, inserting at least a portion of a nasal spray delivery device into one of the guide elements, and activating the nasal spray delivery device to deliver a nasal spray to a lateral wall of the respective nasal cavity.

First claim

1 . A nasal spray delivery guide comprising:
a pair of guide elements spaced apart from one another and configured to be at least partially inserted into respective nostrils of a patient, each guide element comprising an aperture extending therethrough from a base end to a tip end of the guide element; and a flexible connector element attached to and extending between the guide elements.

2 . The nasal spray delivery guide of claim 1 , wherein each guide element is configured to direct a nasal spray to a lateral wall of a respective nasal cavity at an angle of between approximately 20 degrees and approximately 40 degrees from a floor of the patient's nose.

3 . The nasal spray delivery guide of claim 1 , wherein the guide elements have a generally conical shape with axial cross sections decreasing from the base end to the tip end.

4 . The nasal spray delivery guide of claim 1 , wherein the delivery guide has a stable conformation in which an angle between longitudinal axes of the guide elements is between approximately 10 degrees and approximately 30 degrees.

5 . The nasal spray delivery guide of claim 4 , wherein the delivery guide is configured to be temporarily deformed into a non-stable conformation in which the longitudinal axes of the guide elements are substantially parallel to one another.

6 . The nasal spray delivery device of claim 5 , wherein the delivery guide is configured to be temporarily deformed into the non-stable conformation upon application of a force of between approximately 0.5 Newtons and approximately 15 Newtons.

7 . The nasal spray delivery device of claim 6 , wherein the delivery guide is configured to return to the stable conformation upon removal of the force.

8 . The nasal spray delivery device of claim 1 , wherein the flexible connector element is formed as a rod attached to and extending between the guide elements.

9 . The nasal spray delivery device of claim 8 , wherein the rod has a stable conformation in which an angle between longitudinal axes of the guide elements is between approximately 10 degrees and approximately 30 degrees, and wherein the rod is configured to be temporarily deformed into a non-stable conformation in which the longitudinal axes of the guide elements are generally parallel to one another.

10 . The nasal spray delivery device of claim 1 , wherein the flexible connector element is formed as a sheet attached to and extending between the guide elements.

11 . The nasal spray delivery device of claim 10 , wherein the sheet has a stable conformation in which an angle between longitudinal axes of the guide elements is between approximately 10 degrees and approximately 30 degrees, and wherein the sheet is configured to be temporarily deformed into a non-stable conformation in which the longitudinal axes of the guide elements are generally parallel to one another.

12 . A method for delivering a nasal spray into a patient's nose, the method comprising:
providing a nasal spray delivery guide comprising:
a pair of guide elements spaced apart from one another, each guide element comprising an aperture extending therethrough from a base end to a tip end of the guide element; and
a flexible connector element attached to and extending between the guide elements;
inserting the guide elements at least partially into respective nostrils of the patient; inserting at least a portion of a nasal spray delivery device into one of the guide elements; and activating the nasal spray delivery device to deliver a nasal spray to a lateral wall of a respective nasal cavity.

13 . The method of claim 12 , wherein each guide element is configured to direct the nasal spray to the lateral wall of the respective nasal cavity at an angle of between approximately 20 degrees and approximately 40 degrees from a floor of the patient's nose, and wherein inserting at least the portion of the nasal spray delivery device into one of the guide elements comprises inserting a nozzle of the nasal spray delivery device into the aperture of the one of the guide elements such that the nasal spray delivery device is oriented to deliver the nasal spray to the lateral wall of the respective nasal cavity.

14 . The method of claim 12 , wherein the delivery guide has a stable conformation in which an angle between longitudinal axes of the guide elements is between approximately 10 degrees and approximately 30 degrees, and wherein the delivery guide is configured to be temporarily deformed into a non-stable conformation in which the longitudinal axes of the guide elements are generally parallel to one another.

15 . The method of claim 14 , further comprising, prior to inserting the guide elements at least partially into respective nostrils of the patient, temporarily deforming the delivery guide into the non-stable conformation.

16 . The method of claim 15 , wherein temporarily deforming the delivery guide into the non-stable conformation comprises applying a force of between approximately 0.5 Newtons and approximately 15 Newtons to the delivery guide.

17 . The method of claim 15 , further comprising, after inserting the guide elements at least partially into respective nostrils of the patient, allowing the delivery guide to return to the stable conformation.

18 . A nasal spray delivery system comprising:
a nasal spray delivery device; a nasal spray delivery guide comprising:
a pair of guide elements spaced apart from one another and configured to be at least partially inserted into respective nostrils of a patient, each guide element comprising an aperture extending therethrough from a base end to a tip end of the guide element; and
a flexible connector element attached to and extending between the guide elements; and
a clip removably attached to the nasal spray delivery device; wherein the nasal spray delivery guide is removably coupled to the nasal spray delivery device via the clip.

19 . The nasal spray delivery system of claim 18 , wherein the clip is formed as a contoured wire having a generally “C” shape.

20 . The nasal spray delivery system of claim 19 , wherein the clip comprises a semi-circular bend positioned at or near an apex thereof and defining a notch therein, and wherein the semi-circular bend of the clip engages the flexible connector element of the delivery guide.
