Nasal implant introduced through a non-surgical injection technique
A method for non-surgically treating an internal nasal valve of a patient comprising, injecting a working device into the internal nasal valve of the patient, wherein the injected working device in the nasal tissue causes an alteration of an internal or external nasal valve. A device introduced by injection into the nose, allowing for structural support or filling of defects in the nose, and causing a change in external shape of the nose. The device and inserts and implants described also have use in cosmetic applications relating to the facial tissue.
1. A method for implanting a nasal implant, comprising:
transmucossally puncturing an introducing needle through an internal mucosa of a lateral nasal wall of a nose into nasal tissue of the nose at a puncture site within a nasal cavity of the nose, wherein the puncture site is at a vestibule of the nose, wherein puncturing the introducing needle through the nasal tissue at the puncture site is performed without forming an incision at the puncture site prior to puncturing the introducing needle through the nasal tissue at the puncture site, wherein the introducing needle comprises a hollow core that extends to a distalmost end of the introducing needle, wherein the distalmost end of the introducing needle is a beveled tip for puncturing the nasal tissue;
after puncturing the introducing needle into the nasal tissue at the puncture site, advancing the introducing needle through the nasal tissue to a site of implantation in the nose;
after advancing the introducing needle through the nasal tissue to the site of implantation, moving the nasal implant relative to the hollow core and out of the distalmost end of the introducing needle to deposit the nasal implant at the site of implantation in the nasal tissue of the nose; and
removing the introducing needle from the nasal tissue via the puncture site.
2. The method of claim 1 , wherein, when deposited at the site of implantation, the nasal implant extends from a lateral cartilage of the nose to a position over a maxillary bone of the nose.
3. The method of claim 1 , wherein puncturing the introducing needle into the nasal tissue is performed while the nasal implant is in the hollow core of the introducing needle.
4. The method of claim 1 , further comprising, responsive to moving the nasal implant relative to the hollow core, changing a shape of the nasal implant from a first shape to a second shape.
5. The method of claim 4 , wherein the nasal implant is a spring structure.
6. The method of claim 4 , wherein the nasal implant is expandable from the first shape to the second shape.
7. The method of claim 1 , wherein the nasal implant comprises a coating.
8. The method of claim 1 , wherein the nasal implant comprises a degradable component and a non-degradable component.
9. The method of claim 1 , wherein the nasal implant is bioabsorbable.
10. The method of claim 1 , further comprising applying a topical local anesthetic to the nose prior to puncturing an introducing needle into the nasal tissue.
11. The method of claim 1 , wherein the introducing needle comprises an advancement shaft, and wherein moving the nasal implant relative to the hollow core of the introducing needle comprises moving the advancement shaft relative to the hollow core.
12. The method of claim 11 , wherein the introducing needle further comprises a stop that prevents the advancement shaft from moving relative to the hollow core after the nasal implant is deposited at the site of implantation.
13. The method of claim 11 , wherein the hollow core has a straight shape.
14. The method of claim 1 , wherein, at the site of implantation, the nasal implant is entirely within the nasal tissue.
15. The method of claim 1 , wherein puncturing the introducing needle into the nasal tissue and advancing the introducing needle are performed under direct visualization of the nose and the introducing needle.
16. The method of claim 1 , wherein the nasal implant comprises a tapered rod.
17. The method of claim 1 , wherein the nasal implant comprises a rod having a cross-sectional thickness of 1 millimeter.
18. The method of claim 1 , further comprising supporting a nasal airway with the nasal implant to thereby prevent the nasal airway from collapsing during inspiration.
19. The method of claim 1 , wherein a distal end of the nasal implant is delivered out the distalmost end of the introducing needle before a proximal end of the nasal implant.
20. The method of claim 7 , further comprising eluting a drug from the nasal implant to the nasal tissue.
