The present disclosure relates generally to nasal implants, including those for use in rhinoplasty.
Rhinoplasty is a procedure pertaining to nasal reconstruction performed as a result of one or more of a variety of reasons including, but not limited to, injury, congenital defects, and personal aesthetic desire. Rhinoplasty includes nasal augmentation, and such augmentation often involves implantation of a nasal implant.
To date, technological advances and improvements in nasal implants have been generally directed to material or composition improvements. However, little progress has been made relating to improvements to the functional and aesthetic portions, features, and designs of nasal implants.
Presently, nasal implants come in a limited variety of shapes and sizes, including cursorily hand-crafted rectangular prism shaped nasal implants, which are very common among those of lay surgeons, and symmetrically shielded, L-shaped nasal implants.
It is recognized herein that patients, that is, recipients of nasal implants, more often than not encounter one or more undesirable complications with their implanted nasal implants, including visible depressions and/or lines in or about the edges of the implanted nasal implant; concave-shaped nasal dorsum; undesirably wide dorsum due to, among other things, a lack of understanding and consideration by the surgeon and/or manufacturer/designer of the nasal implant of the variations in thickness of relevant areas of the nose; displacement of the nasal implant after implantation, including vertical, horizontal, and/or rotational displacement; inflexibility of one or more portions of the implanted nasal implant; and more serious consequences, including causing perforations to one or more parts of the nose, including the tip of the nose, and causing permanent deformity resulting from sinking and/or breaking into the gap between parts of the nose, including those between the lower lateral cartilages.
Present example embodiments relate generally to a nasal implant comprising an elongated body portion, an elongated tail portion, a first wing portion, a head portion, a second wing portion, and a leg portion. The body portion forms a central axis and comprises opposing inner body and outer body surfaces, the inner body surface having a ventral groove portion disposed substantially parallel to the central axis, and the outer body surface having a ridge portion. The ventral groove portion comprises a deepest portion in proximate correspondence to a highest portion of the ridge portion with respect to the central axis. A lower portion of the tail portion is in communication with at least an upper portion of the body portion, wherein an angle formable between an axis definable by the tail portion and the central axis is between 0-90 degrees. The first wing portion comprises opposing inner first wing and outer first wing surfaces, wherein an inner portion of the first wing portion is in communication with at least a first outer portion of the body portion.

For a more complete understanding of the present disclosure, example embodiments, and their advantages, reference is now made to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and:
Although similar reference numbers may be used to refer to similar elements for convenience, it can be appreciated that each of the various example embodiments may be considered to be distinct variations.
Example embodiments will now be described hereinafter with reference to the accompanying drawings, which form a part hereof, and which illustrate example embodiments which may be practiced. As used in the disclosures and the appended claims, terms such as “example embodiment” and “present embodiment” do not necessarily refer to a single embodiment, although they may, and various example embodiments may be readily combined and interchanged, without departing from the scope or spirit of example embodiments. Furthermore, the terminology as used herein is for the purpose of describing example embodiments only and is not intended to be limitations. In this respect, as used herein, the term “in” may include “in” and “on”, and the terms “a”, “an” and “the” may include singular and plural references. Furthermore, as used herein, the term “by” may also mean “from”, depending on the context. Furthermore, as used herein, the term “if” may also mean “when” or “upon”, depending on the context. Furthermore, as used herein, the words “and/or” may refer to and encompass any and all possible combinations of one or more of the associated listed items.
Presently, nasal implants may be broadly categorized into three types. A first type of nasal implant comprises a short, substantially straight tail. As used herein, a tail will refer to the top part of a nasal implant. Typically, the angle of the tail relative to the remaining part of the nasal implant will be in or about 180 degrees, which, when implanted, will cause an unnatural look and feel in most patients.
A second type of nasal implant comprises protruding sides. Typical protruding sides comprise incorrect proportions and shapes, such as being overly thick and relatively hard to bend in a natural manner, and often causes inclining toward one or more sides of the nose when the nasal implant is implanted. It is recognized herein that typical protruding sides will cause obtrusive depressions when the nasal implant is implanted, especially in patients having relatively thin nasal skin.
A third type of nasal implant is of the type that is shielded and comprises an “L” shaped body. A shield is generally attached at the head of nasal implant, which corresponds to the portion of the nasal implant that presses against an inner surface of the tip of a patients' nose. However, it is recognized herein that even with the support of a shield, patients often suffer eventual perforation at the tip of the patients' nose because shields of such nasal implants typically have incorrect angles and/or sizes. For example, on the one hand, if the shield is not sufficiently large, the pressure at the tip of the patients' nose will be high and will cause said perforations over time. On the other hand, if the shield is overly large, the result will be aesthetically unpleasant and the overall weight of the nasal implant will be large, causing said perforations over time and/or other complications. In addition, if the shield is not fixedly implanted at a proper angle, then only a small portion of the shield will provide surface contact with the inner surface of the patients' nose, resulting in unduly high pressure at the said small portion of the inner surface of the patients' nose and, over time, causing said undesirable perforations.
Present example embodiments provide for one or more advantages over conventional nasal implants and implantation procedures thereof, including advantages over those problems described above and herein, and include, but are not limited to: preserving natural curvatures and/or angles in or about the root of a patients' nose; providing straight and naturally narrow nasal dorsa; substantially eliminating conspicuous depressions; providing for more secureness from displacements when the nasal implant is implanted; providing more natural flexibility and feeling when the nasal implant is implanted; substantially eliminating sinking and/or breaking into gaps between greater alar cartilages; substantially eliminating perforation in or about the tip of the nose; and enabling modifications and/or customizations based on the patients' needs and/or desires.

Second wing portion 80 may be one or more of a rectangular shape, pentagonal shape, hexagonal shape, circular shape, and any other geometric shapes. Leg portion 84 may be one or more of a straight leg, triangular leg, rectangular leg, pentagonal leg, hexagonal leg, any other geometric legs, leg with base or bases at its end, and legs of any other shapes are possible. Furthermore, shapes on any portions may also be possible—for example, making one or more holes, cavities, protrusions, and/or channels, however small, cutting, hollowing, and making patterns or shapes for better holding.
In example embodiments, deviations, regardless of extent, from one or more dimensions specified of each portion, however small, including height, width, depth, length, thickness, and angle may be applied to nasal implant 100.
In example embodiments, the portions of nasal implant 100 may be of heterogeneous and/or homogenous composition. For example, an example embodiment of nasal implant 100 may comprise head portion 74 having soft-grade silicone composition, whereas the rest of nasal implant 100 may comprise hard-grade silicone. As another example, nasal implant 100 may be impregnated with other substances. Any substances that do not induce malign effects to the nasal tissues can be elected—regardless of their physical properties, such as hardness, roughness, flexibility, and being porous. The four substances described above and herein, namely silicone, expanded polytetrafluoroethylene (ePTFE), polyethylene, and hydroxyapatite, are merely examples of various substances that may be for use in nasal implant 100.
It is recognized herein that present example embodiments provide for one or more of the following advantages: preservation of one or more sizes of angles and continuous curves at the roots of noses; no conspicuous depressions; resultant nasal dorsa will be relatively narrow and straight; nasal implants will be less susceptible to displacement, rotation, and inclining; resultant noses will be more naturally flexible, providing natural looks for the patient; less probable to perforation at the tips of noses and to sink and break into greater alar cartilages; less excessive weight, and, hence, patients can feel more comfortable; nasal implants are easily and conveniently adaptable and customizable so as to cope with the wide variation on shapes of noses; and enables recipient patients' own surrounding nasal tissues to recover (heal) and grow around the nasal implant so as to provide support of the nasal implant.

Specifically, a description of a technology in the “Background” section shall not be construed as an admission that technology is prior art to any invention(s) in this disclosure. Furthermore, any reference in this disclosure to “invention” in the singular should not be used to argue that there is only a single point of novelty in this disclosure. Multiple inventions may be set forth according to the limitations of the multiple claims issuing from this disclosure, and such claims accordingly define the invention(s), and their equivalents, that are protected thereby. In all instances, the scope of such claims shall be considered on their own merits in light of this disclosure, but should not be constrained by the headings in the present disclosure.
