Description

JAW AUGMENTATION IMPLANTS, METHODS AND USES BACKGROUND

[0001] This application claims the benefit of priority and is entitled to the filing date pursuant to 35 USC § 119(e) of U.S. Provisional Patent Application 63 / 087,801, filed on October 5, 2020, the contents of which are incorporated herein by reference in their entirety.

[0002] The invention relates, in some aspects, to mandibular augmentation implants and implantation methods.

[0003] The chin is an important and prominent region of the lower face. For example, a well-defined jawline is the cornerstone of a balanced and attractive face, whether masculine or feminine. Therefore, many people are bothered by a receding or weak chin, as it detracts from their facial appearance. A receding chin can create facial features that lack aesthetically pleasing proportion, including, for example, a full or double chin, making a perfectly sized nose appear too large, or making the neck look fleshy.

[0004] Mandibular augmentation or enhancement surgery, also called mentoplasty, can correct a weak or receding chin by strengthening its appearance, providing proportion to the chin, improving the contours of the neck and jawline, and / or restoring overall balance to an individual's facial appearance and profile. The surgery typically involves placing an implant around the patient's existing jawline to augment the size and shape of the chin and achieve a more attractive and natural balance among facial features.

[0005] However, the anatomical features of the chin have limited the effectiveness of current surgical procedures for mandibular augmentation or enhancement. For example, the mandibular retaining ligaments restrict the extent to which a chin implant can be placed, thus limiting the size of the implant and the region in which it can be positioned. These size and location limitations impose restrictions on the extent to which a chin can be augmented or enhanced. Therefore, there is a need for improved surgical procedures for mandibular augmentation or enhancement. The present invention describes such improved surgical procedures as well as novel chin implants that can now be used advantageously for mandibular augmentation or enhancement due to these improved procedures. BRIEF DESCRIPTION

[0006] Aspects of the present invention describe a mandibular implant comprising a body having a substantially U-shaped structure comprising a first end region and a second end region, the body made to a size and dimensioned to an axial length p LOfrcn / eznz / q / Yi configured to extend from a point located in a region between an attachment location of a left mandibular osteocutaneous ligament and a left gonial angle to a region between the attachment location of the right mandibular osteocutaneous ligament and the right gonial angle. The described mandibular implant may have an axial length extending beyond the attachment location of the left mandibular osteocutaneous ligament by about 3 mm to about 5 cm and extending beyond the attachment location of the right mandibular osteocutaneous ligament by about 3 mm to about 5 cm.and may have an axial length extending to the left gonial angle and the right gonial angle. The mandibular implant according to claim 1, wherein a body of a mandibular implant described herein may comprise a chin arch, a left lateral arm and a right lateral arm and may further comprise a branch extension projecting superiorly from an upper edge of the first extreme region of the body or left lateral arm and / or a branch extension projecting superiorly from an upper edge of the second extreme region of the body or right lateral arm.Furthermore, a mandibular implant body described herein may further comprise one or more protrusions projecting radially outward from an external surface of the body, and / or one or more tabs projecting posteriorly from an internal surface of the body, said tabs comprising a base tab, a submental tab, an extended tab, or any combination thereof. The described body has an external surface and an internal surface, each of which may be smooth or textured. The described body is composed of implantable biomaterial and may be flexible and have a unitary structure or comprise an outer shell and an inner core, the shell being a single layer or a plurality of layers. The disclosed body may also be configured with an internal cavity space that can be substantially filled with a filling material.

[0007] Other aspects of the present invention describe a method of mandibular augmentation or enhancement. The methods described comprise accessing one or more segments of a left and / or right anterior mental fibrous condensation; releasing one or more segments of the left and / or right anterior mental fibrous condensation from their respective mandibular attachment sites; subperiosteally releasing one or more mandibular ligaments from their respective mandibular attachment points to form a subperiosteal implantation cavity; and inserting a mandibular implant into the subperiosteal implantation cavity. A method described herein may create a subperiosteal implantation cavity that extends laterally any distance beyond an attachment site of one or more mandibular ligaments, such as a mandibulocutaneous ligament.After insertion of the mandibular implant using a method described herein, the implant acts as a retractor to retain the periosteum above the mandible and inhibit periosteal reinsertion. It can increase the mandibular area by a volume that is at least approximately 20% greater than the volume of the mandibular implant. A method described herein provides that the inserted mandibular implant increases the mandibular area from a point posterior to the attachment site of a left mandibulocutaneous ligament to a point posterior to the attachment site of a right mandibulocutaneous ligament. A method described herein can lift, reduce, or eliminate a double chin and can be performed with or without a concomitant facelift and / or dermal filler procedure.Other aspects of the present invention describe a mandibular implant described herein for use in augmenting or enhancing the jaw of an individual. Other aspects of the present invention describe the use of a mandibular implant described herein for augmenting or enhancing the jaw of an individual. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] As illustrated in Figures 1A-1C, the mandible is the largest bone of the human skull and consists of three parts: the central body, the left ramus, and the right ramus. The body is the anterior portion of the mandible. The mandibular body is a substantially U-shaped structure, with a central frontal portion (or base of the U) and two lateral portions (or shaft of the U). It is bounded by a superior alveolar border and an inferior basal border and external (or anterior) and internal (or posterior) surfaces. The alveolar border contains the hollow cavities in which the sixteen lower teeth reside, while the basal border forms the line of the mandible.

[0025] With reference to Figures 1A and B, the central anterior portion of the mandibular body is generally rectangular in shape. Its external surface contains the mandibular symphysis, a midline ridge that divides this portion into two halves. The lower end of the ridge expands laterally to form the centrally located mental protuberance, a prominence that forms the chin. This prominence extends laterally from the lower left and right portions of the mental protuberance to form the left and right mental tubercles. The mandibular symphysis, the superior border of the mental protuberance, and the left and right mental tubercles create a left and right depression on either side of the midline. Each of these two depressions contains a mental foramen, an opening through which the mental nerve and vessels exit.The right and left portions of the mandibular body are curved and rectangular in shape. The external surface of each can be divided into two parts: the alveolar portion located superiorly and the horizontally curved base portion located inferiorly. The mandibular line is formed by the inferior portions of the left and right mental tubercles and the inferior portions of the base portion, which together define the basal border. p LOfrcn / eznz / q / Yi

[0026] The left and right rami are each vertical processes arising superiorly from each lateral portion of the mandibular body. The rami join the body at the angle of the mandible, also known as the gonial angle. On the superior surface of each ramus, the coronoid and condylar processes articulate with the temporal bone to create the temporomandibular joint, which allows for movement.

[0027] Covering the mandible is the periosteum. The periosteum is a dense irregular connective tissue divided into an outer fibrous layer and an inner cambium layer (or osteogenic layer). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts.

[0028] The retaining ligaments of the face are strong, deep fibrous attachments that originate from the periosteum or deep facial fascia and run perpendicularly through the facial layers to insert into the dermis. These ligaments act as anchoring points, retaining and stabilizing the skin and superficial fascia with the underlying deep fascia and facial skeleton at defined anatomical locations. Microscopically, each ligament has its roots in a tree-like distribution as a deep periosteal or fascial fatloat that divides as it approaches the musculoaponeurotic system (SMAS) into numerous branches, which insert into the dermis. This branching network of fibers is called the cutis retinacula, which is part of a larger, more complex system of fibrous septa in the subcutaneous layer.Retaining ligaments can be divided into true retaining ligaments and false retaining ligaments (also called septa or adhesions). True retaining ligaments are defined as ligaments that insert directly into the dermis. As illustrated in Figure 2A, the true retaining ligaments that support the subcutaneous tissues of the face include the orbital ligaments, the zygomatic ligaments, the buccal-maxillary ligaments (maxillary portion), and the mandibular ligaments. False retaining ligaments are defined as ligaments that insert directly into the SMAS and thus have an indirect effect on the dermis through the retinacular skin. As illustrated in Figure 2B, the false retaining ligaments of the face include the platysma-auricular ligaments, the masseteric-cutaneous ligaments, and the buccal-maxillary ligaments (buccal portion).The facial ligaments are important for understanding the concepts of facial aging and rejuvenation. They are located in consistent anatomical positions where they separate facial spaces and compartments. Their superficial extensions form subcutaneous septa that separate the facial fat compartments.

[0029] Over the past 30 years, several concepts of facelift surgery have been advanced. Starting with a skin lift, then progressing to a superficial musculoaponeurotic system (SMAS) and extended SMAS dissection, the deep plane facelift, and then popularizing the endoscopic brow lift, which later extended down to the subperiosteal facelift. However, common problems with a subperiosteal facelift include the fact that the retaining ligaments of the face and the periosteum are not stretched, and the periosteum, once lifted, quickly adheres to the bone. In this way, most of the benefit of the periosteal facelift is diminished, and many patients with conventional facelifts have questioned the reduced longevity of their results.

[0030] Without wishing to be limited to any particular theory, an inventive aspect of the present invention is based on the discovery of an aponeurotic condensation of fibrous tissue, referred to herein as the anterior mental fibrous condensation. The present invention is based on the finding that separating the left and right anterior mental fibrous condensations at their periosteal insertion site(s), together with surgical manipulation of the left and right mandibular ligaments, can provide unexpected and surprising synergistic benefits to a mandibular augmentation or enhancement procedure, as well as to a facelift procedure. For example, a method described herein synergistically mobilizes the mental soft tissue and volumetrically augments the chin above and beyond what would be expected from implanting a chin implant alone.Furthermore, the surgical manipulation described herein provides an improved surgical procedure for mandibular augmentation or enhancement by greatly expanding the locations where a mandibular implant can be placed. Moreover, because the described surgical procedure increases the number of available mandibular implant locations, new chin implants of various sizes and shapes can now be created and used to advantage. Finally, the described method also allows a mandibular implant to be used beneficially as a retractor to prevent or reduce the reattachment of the periosteum to the overlying soft tissue of the bone. Inhibiting or reducing the reattachment of the periosteum to the mandible ensures that the soft tissue of the face remains elevated.In this way, the described method improves upon conventional facelift procedures by preventing or reducing the expected postoperative recurrence of soft tissue retraction to its preoperative position.

[0031] The disclosed method of mandibular augmentation or enhancement comprises the surgical manipulation of the left and right anterior mental fibrous condensations in conjunction with the anatomy of the left and right mandibular ligaments. As illustrated in Figures 3A and 3B, the left and right anterior mental fibrous condensations are located on the mental tubercles of the mandible. An aponeurotic condensation of fibrous tissue, each anterior mental fibrous condensation has been found to typically include a plurality of segments of anterior mental fibrous condensation separated from each other, as illustrated in Figure 3A, although they may not be segmented or separated depending on the anatomy of an individual patient. p LOfrcn / eznz / q / Yi Each anterior mental fibrous condensation is interwoven into the periosteum at a deep origin site in the left and right mental tubercles and extends and inserts through the soft tissue layers.

[0032] As illustrated in Figures 2A and 3B, the left and right mandibular ligaments are retaining ligaments that originate from the periosteum and insert directly into the dermis to create strong, deep fibrous attachments. The left and right mandibular ligaments are lateral to the left and right anterior mental fibrous condensations, respectively. These ligaments, which measure approximately 2 cm horizontally and 1.2 cm vertically, are located about 4.5 cm anterior to the gonial angle of the mandible, below the left and right mental foramina, and about 1 cm above the border of the base of the mandible. Each of the left and right mandibular ligaments is composed of two distinct fibrous insertions located about 2 mm to 3 mm apart, called the medial mandibular ligament and the mandibulocutaneous ligaments.

[0033] In some modalities, and as shown in Figures 4A-4D, a disclosed method of mandibular augmentation or enhancement comprises 1) accessing one or more segments of the left and / or right anterior mental fibrous condensation; 2) releasing the one or more segments of the left and / or right anterior mental fibrous condensation; 3) subperiosteally releasing one or more mandibular ligaments to form an implantation cavity; and 4) inserting a mandibular implant into the implantation cavity.

[0034] In some modalities, a method described herein comprises accessing one or more segments of a left and / or right anterior mental fibrous condensation by creating a skin incision, as illustrated in Figure 4A. In some modalities, access to one or more segments of a left and / or right anterior mental fibrous condensation can be achieved by creating a skin incision within the submental space. For example, an inverted V-shaped incision can be made around the mandibular line at the posterior aspect of the base margin and then dissected through the soft tissue below the incision site until the attachment points of one or more segments of the right and / or left anterior mental fibrous condensations are identified on the external surface of the mandible.In some modalities, access to the anterior mental fibrous condensation segments can be achieved by creating an intraoral incision through the vestibule of the mouth. For example, an incision can be made near the mental protuberance, and then deep dissection can be performed through the soft tissue underlying the incision site. Once the subperiosteal level is reached by deepening and extending the dissection, the one or more attachment points of the left and / or right anterior mental fibrous condensation segments can be identified on the external surface of the mandible.

[0035] In some modalities, a method described herein comprises releasing one or more segments of the left and / or right anterior mental fibrous condensation from its mandibular attachment point. Once identified, the one or more segments of the left and / or right anterior mental fibrous condensation are incised and released at the subperiosteal and periosteal levels at their attachment sites located on the mental tubercles of the mandible, as illustrated in Figure 4B. In some modalities, the one or more segments of the left and right anterior mental fibrous condensation may be released by excising and cutting their respective attachment sites located on the mental tubercles of the mandible using a cutting device, such as, for example, a scalpel, scissors, an electromagnetic energy device (e.g., electrocautery), and the like.

[0036] In some modalities, a method described herein comprises the subperiosteal release of one or more mandibular ligaments from one or more of their mandibular attachment points to form a subperiosteal implantation cavity. After releasing one or more segments of the left and / or right anterior mental fibrous condensations, the left and right mandibular ligaments and overlying soft tissue can be released from the mandibular body to form a subperiosteal implantation cavity or pocket. In some modalities, the left and / or right mandibular ligaments and overlying soft tissue are released from the mandibular body by blunt dissection of the medial mandibular and mandibulocutaneous ligaments at the subperiosteal level using a periosteal elevator.As shown in Figures 4B and 4C, finger placement locates the position of the mental foramen and the mandibular line. This technique securely maintains the subperiosteal dissection within the area of ​​the inferior border of the mandibular body and well below the mental foramen and its exiting mental nerve, allowing simple and safe access to the parasymphyseal areas. Once one or more mandibular ligaments are elevated from the bony surface to the subperiosteal level, continued blunt dissection can easily extend the subperiosteal implantation cavity or pocket laterally without resistance. A subperiosteal implantation cavity or pocket can extend laterally any distance beyond the attachment site of a mandibulocutaneous ligament.In some modalities, a subperiosteal implantation pocket or cavity may extend laterally any distance beyond a mandibulocutaneous ligament attachment site and up to the gonial angle of the mandible. In some modalities, a subperiosteal implantation pocket or cavity may extend laterally midway between a mandibulocutaneous ligament attachment site and the gonial angle of the mandible. In some modalities, a subperiosteal implantation pocket or cavity may extend laterally to the gonial angle of the mandible. As shown in Figure 4C, the placement of a periosteal elevator over the mandibular line illustrates the direction and location where a subperiosteal pocket can be formed using the described method.

[0037] In some modalities, a method described herein involves the insertion of a mandibular implant into the implantation cavity. As depicted in Figure 4D, a larger pocket can be created once the medial mandibular and mandibulocutaneous ligaments are elevated and the subperiosteal implantation cavity is extended to the desired length, so that a larger, variably shaped mandibular implant can then be inserted into the cavity. Proper implant placement can be highly beneficial in creating an improved esthetic result. The implant can be placed at the lower border of the mandible, rather than at a higher location, since the release of the left and right anterior mental fibrous condensations along with the left and right mandibular ligaments allows for the proper placement of a mandibular implant.In some procedures, a mandibular implant can be placed so that the lower edge of the implant on the midline of the mandible is approximately 2 cm, 1.5 cm, 1 cm, 0.5 cm, or less from the midline, or within a radius of approximately 2 cm from the chin (attaching to the mental tubercle) and the base of the mandible. Once the mandibular implant is in place, the skin incision is closed to complete the mandibular augmentation or enhancement procedure described herein.

[0038] The method described herein releases the surrounding soft tissue to allow it to rotate and advance without restriction. This not only beneficially increases anterior projection, but by rotating the soft tissue (from the submental area), it also enhances the appearance of vertical dimension throughout the anterior mandibular area. Furthermore, by elevating and allowing the soft tissue in the medial mandibular and mandibulocutaneous ligaments to reposition itself upward and outward, it has the capacity to exponentially add overall volume to the entire area, thus providing an unexpected synergistic benefit in all dimensions of the appearance of the entire lower third of the face. Such results would not be achieved by simply placing an ordinary mandibular implant without addressing the anterior mental fibrous condensation and / or the mandibular ligaments.

[0039] In some modalities, mandibular implants may include inferior and / or anterior extensions of the implant inserted beneath the incised body structures and laterally to ensure that the area of ​​bone at the junction of the medial mandibular and mandibulocutaneous ligaments is fully covered to guarantee that the periosteum remains elevated and does not reattach to the underlying bone. In some modalities, a mandibular implant incorporates a section to ensure that the implant is inserted beneath structures that are surgically released and / or elevated along with the periosteum or other structures and / or geometries as described later in this document.

[0040] In some modalities, the synergistic augmentation volume provided by a method described herein exceeds the implant volume. The volume could be projected, for example, uniformly or unevenly in one or more of the anteroposterior and / or vertical dimensions with different percentage values ​​or intervals as described above. In some modalities, the synergistic augmentation volume provided by a method described herein above and beyond the implant volume may be, for example, approximately 10%, approximately 20%, approximately 30%, approximately 40%, approximately 50%, approximately 60%, approximately 70%, approximately 80%, approximately 90%, approximately 100%, or more. In some modalities, the synergistic augmentation volume provided by a method described in this document above and beyond the implant volume may be, for example, at least 10%, at least 20%,at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 100% or more. In some modalities, the synergistic augmentation volume provided by a method described herein above and beyond the implant volume may be, for example, at most 10%, at most 20%, at most 30%, at most 40%, at most 50%, at most 60%, at most 70%, at most 80%, at most 90%, at most 100%. In some modalities, the synergistic augmentation volume provided by a method described herein above and beyond the implant volume may be, for example, around 10% to around 20%, around 10% to around 30%, around 10% to around 40%, around 10% to around 50%, around 10% to around 60%, around 10% to around 70%, around 10% to around 80%, around 10% to around 90%,around 10% to around 100%, around 20% to around 30%, around 20% to around 40%, around 20% to around 50%, around 20% to around 60%, around 20% to around 70%, around 20% to around 80%, around 20% to around 90%, around 20% to around 100%, around 30% to around 40%, around 30% to around 50%, around 30% to around 60%, around 30% to around 70%, around 30% to around 80%, around 30% to around 90%, around 30% to around 100%, around 40% to around 50%, around 40% to around 60%, around 40% to around 70%, around 40% to around 80%, around 40% to around 90%, around 40% to around 100%, around 50% to around 60%, around 50% to around 70%, around 50% to around 80%, around 50% to around 90%,around 50% to around 100%, around 60% to around 70%, around 60% to around 80%, around 60% to around 90%, around 60% to around 100%, around 70% to around 80%, around 70% to around 90%, around 70% to around 100%, around 80% to around 90%, around 80% to around 100%, or around 90% to around 100%. p LOfrcn / eznz / q / Yi

[0041] In some modalities, a method described herein can substantially enhance the chin. For example, Figure 4E shows a photograph of an individual before mandibular augmentation or enhancement using a method described herein, while Figure 4F shows a photograph of the same individual after the insertion of a mandibular implant (from the chin to the gonial angle) that displaces the soft tissue and smooths depressions or deficiencies of the adjacent soft tissue using a disclosed method. Figure 4F clearly demonstrates a superior clinical result of mandibular augmentation or enhancement using a method described herein whereby the implant lifts and enhances the mandible.

[0042] Facial implants are known to be used to augment or project over a designated area of ​​the facial skeleton by virtue of their particular volume and geometry. In some modalities, a facelift procedure (e.g., rhytidectomy) is performed simultaneously with a mandibular augmentation or enhancement method described herein. In some modalities, any number of the true ligaments of the cheek or forehead, such as, for example, the orbital ligaments, the zygomatic ligaments, and the buccal-maxillary ligaments (maxillary portion), may be cut, excised, or released (and / or left alone and untouched). In some modalities, a method described herein disturbs or excises the true ligaments of the cheek or forehead.In some modalities, any number of the false ligaments of the cheek or forehead, such as, for example, the platysma-auricular ligaments, the masseteric-cutaneous ligaments, and the buccal-maxillary ligaments (buccal portion), may be cut, excised, or released (and / or left alone and intact). In some modalities, a method described herein disturbs or excises false ligaments of the cheek or forehead. In some modalities, no facelift procedure is required or performed in conjunction with a mandibular augmentation or enhancement method described herein.

[0043] In some modalities, a disclosed method may include augmenting a facial feature with one or more dermal filler materials, for example, injected into a region of the face such as the chin, in addition to, or instead of, implanting a long-term implant.

[0044] Although primarily described with regard to the treatment of the chin, some modalities of the invention may also be used or modified for use with other anatomical regions, including the midface, other areas of the face, or other parts of the body, for example.

[0045] Given the various implant pockets that can be created, a variety of chin implants can be used with methods and applications such as those described herein. Chin implants could be conventional, or they could also include enhanced mandibular implants such as those described herein. For example, in some modalities, a mandibular implant described herein is configured to augment tissue from the end of the left gonial angle (posterior mandible) to the end of the right gonial angle (posterior mandible) of an individual.In some modalities, a mandibular implant described herein is configured to augment tissue from a point located in a region between the attachment site of the left mandibular osteocutaneous ligament and the left gonial angle (posterior mandible) to a region between the attachment site of the right mandibular osteocutaneous ligament and the right gonial angle (posterior mandible) of an individual.

The chin arch 1510 comprises an outer surface 1512 and an inner surface 1514, an upper part 1516 and a lower part 1518.The mental arch 1510 is sized and dimensioned to fit the general shape of a region of the mental protuberance and the left and right mental tubercles, and the inner surface 1514 of the mental arch 1510 is configured to seat correctly on the upper surface of a region of the mental protuberance and the left and right mental tubercles. The left lateral arm 1520 comprises an outer surface 1522 and an inner surface 1524, an upper portion 1526 and a lower portion 1528. Similarly, the right lateral arm 1530 comprises an outer surface 1532 and an inner surface 1534, an upper portion 1536 and a lower portion 1538. The left and right lateral arms 1520 and 1530 are sized and dimensioned to fit the general shape of the lower portion of the mandibular body.Furthermore, the inner surface 1524 of the left lateral arm 1520 and the inner surface 1534 of the right lateral arm 1530 are each configured to fit correctly on the upper surface of their respective lower portion of the mandibular body. The left and right lateral arms 1520 and 1530 have a length that extends to the gonial angle of the mandible. The size and dimensions of the left and right lateral arms 1520 and 1530 are shaped to impart a full enhancement of the jawline, with the length of each arm gradually decreasing in height and thickness. Each arm has a height of approximately 3 mm to 5 mm and a thickness of approximately 2 mm to 3.5 mm.Furthermore, the chin arch 1510 comprises an extended tongue position 1580 on the lower portion 1528 of the inner surface 1512 of the chin arch 1510 and the lower portion 1528 of the inner surfaces 1522, 1532 of the left and right lateral arms 1520, 1530. The extended tongue 1580 is configured to fit beneath the rim of the left and right chin protuberances and beneath the rim of the left and right portions of the mandibular body base to ensure proper placement of the mandibular implant 1500. The extended tongue 1580 increases the stability of the mandibular implant 1500, prevents fibrous attachment to the mandible, and provides a smooth transition between different or adjacent areas of the mandible.The left and right lateral arms 1520, 1530 also each comprise two protrusions 1540 situated on an outer surface 1524, 1534 of the left and right lateral arms 1520, 1530 respectively.

[0099] In conclusion, the foregoing descriptions of embodiments of the present invention have been presented for illustrative and descriptive purposes. It should be understood that, although aspects of the present invention are highlighted by reference to specific embodiments, a person skilled in the art will readily appreciate that these described embodiments are merely illustrative of the principles comprising the present invention. As such, the specific embodiments are not intended to be exhaustive nor to limit the invention to the precise forms described. Therefore, it should be understood that the embodiments of the disclosed object are in no way limited to any particular element, compound, composition, component, article, apparatus, methodology, use, protocol, step, and / or limitation described herein, unless expressly stated as such.

[0100] Furthermore, the groupings of alternative embodiments, elements, steps, and / or limitations of the present invention shall not be construed as limitations. Each of these groupings may be mentioned and claimed individually or in any combination with other groupings described herein. It is anticipated that one or more alternative embodiments, elements, steps, and / or limitations of a grouping may be added to or removed from the grouping for reasons of convenience and / or patentability. When such addition or removal occurs, the specification shall be deemed to contain the modified grouping, thereby fulfilling the written description of all Markush groups used in the appended claims.

[0101] Furthermore, those skilled in the art will recognize that certain changes, modifications, permutations, alterations, additions, subtractions, and subcombinations thereof may be made in accordance with the teachings of this document without departing from the spirit of the present invention. Moreover, it is intended that the appended claims and the claims presented thereafter be construed to include all changes, modifications, permutations, alterations, additions, subtractions, and subcombinations that are within their true spirit and scope. Accordingly, the scope of the present invention should not be limited precisely to what is shown and described in this specification.

[0102] This document describes certain embodiments of the present invention, including the best means known to the inventors for carrying out the invention. Of course, variations of these embodiments will be obvious to those skilled in the art upon reading the foregoing description. The inventor expects those skilled in the art to employ such variations as appropriate, and the inventors intend that the present invention be practiced in a manner other than that specifically described herein. Accordingly, this invention includes all modifications and subject-matter equivalents mentioned in the appended claims to the extent permitted by applicable law. Furthermore, any combination of the embodiments described above in all possible variations thereof is encompassed by the invention unless otherwise stated herein or clearly contradicted by the context.

[0103] The words, language, and terminology used in this specification are intended to describe particular features, elements, steps, and / or limitations only and are not intended to limit the scope of the present invention, which is defined solely by the claims. Furthermore, such words, language, and terminology should be understood not only in the sense of their commonly defined meanings but also, by special definition in this specification, to include materials or actions beyond the scope of their commonly defined meanings. Therefore, if an element, step, or limitation can be understood in the context of this specification as including more than one meaning, then its use in a claim should be understood as generic for all possible meanings supported by the specification and by the word itself.

[0104] The definitions and meanings of the elements, steps, or limitations listed in a claim stated below are therefore defined in this specification to include not only the combination of elements, steps, or limitations literally stated, but all equivalents, structures, materials, or actions to accomplish substantially the same function or in substantially the same manner to achieve substantially the same result. In this sense, therefore, it is contemplated that an equivalent substitution of any two or more elements, steps, or limitations in a claim stated below may be made, or that a single element, step, or limitation may be substituted for any two or more elements, steps, or limitations in such claim.Although the elements, steps, or limitations may be described above as acting in certain combinations and even initially claimed as such, it should be expressly understood that one or more elements, steps, or limitations of a claimed combination may, in some cases, be omitted from the combination, and that the claimed combination may be directed to a subcombination or a variation of a subcombination. Therefore, notwithstanding that the elements, steps, and / or limitations of a claim are stated below in a particular combination, it should be expressly understood that the invention includes other combinations of fewer, more, or different elements, steps, and / or limitations described above, even if they are not initially claimed in such combinations.Furthermore, insubstantial changes to the claimed object as seen by a person skilled in the art, now known or subsequently devised, are expressly contemplated as equivalent within the scope of the claims. Therefore, obvious substitutions now or later known to a person skilled in the art are defined as being within the scope of the defined elements. Consequently, the claims should be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can obviously be substituted, and what essentially embodies the core idea of ​​the invention.

[0105] Unless otherwise stated, all numbers expressing a feature, item, quantity, parameter, property, term, etc., used in this specification and claims, shall be understood to be modified in all cases by the term "around." As used herein, the term "around" means that the feature, item, quantity, parameter, property, or term so qualified encompasses a range of plus or minus ten percent above and below the value of the indicated feature, item, quantity, parameter, property, or term. Accordingly, unless otherwise stated, the numerical parameters set forth in this specification and accompanying claims are approximations that may vary.For example, since mass spectrometry instruments may vary slightly in determining the mass of a given analyte, the term "around" in the context of the mass of an ion or the mass-to-charge ratio of an ion refers to + / -0.50 atomic mass units. At a minimum, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical indication should be interpreted at least in light of the number of significant digits reported and by applying ordinary rounding techniques. p LOfrcn / eznz / q / Yi

[0106] Although the numerical ranges and values ​​that establish the broad scope of the invention are approximations, the numerical ranges and values ​​stated in the specific examples are reported as accurately as possible. However, any numerical range or value inherently contains certain errors that necessarily result from the standard deviation found in their respective test measurements. The enumeration of numerical ranges of values ​​in this document is intended simply as a shorthand method for referring individually to each separate numerical value that lies within the range. Unless otherwise stated herein, each individual value within a numerical range is incorporated into this specification as if it were individually mentioned herein.

[0107] The use of the terms "could" or "may" in reference to a modality or aspect of a modality also carries the alternative meaning of "could not" or "cannot." Thus, if the present specification reveals that a modality or an aspect of a modality may be included as part of the object of the invention, then the negative limitation or exclusionary condition is also explicitly understood to mean that a modality or an aspect of a modality may not be or cannot be included as part of the inventive matter. Similarly, the use of the term "optionally" in reference to a modality or aspect of a modality means that such modality or aspect of the modality may be included as part of the object of the invention or may not be included as part of the inventive matter.The application of such negative limitation or exclusion condition will be based on whether the negative limitation or exclusion condition is listed in the claimed object.

[0108] The terms a, an, the, and similar references used in the context of the description of the present invention (especially in the context of the following claims) should be construed as covering both the singular and the plural, unless otherwise indicated herein or clearly contradicted by the context. Furthermore, ordinal indicators, such as, for example, first, second, third, etc., for identified elements are used to distinguish between the elements and do not indicate or imply a required or limited number of such elements, nor do they indicate a particular position or order of such elements unless specifically stated otherwise. All methods described herein may be carried out in any suitable order unless otherwise indicated herein or clearly contradicted by the context.The use of any and all examples or illustrative language (e.g., such as) provided herein is intended solely to better illustrate the present invention and does not limit the scope of the otherwise claimed invention. Nothing in this specification should be construed as indicating anything unclaimed that is essential to the practice of the invention.

[0109] When used in the claims, either as presented or added by amendment, the open transitional term comprising, variations thereof such as, for instance, comprise and includes, and equivalent open transitional phrases thereof such as including, containing and having, encompass all expressly enumerated elements, limitations, steps, whole numbers and / or features alone or in combination with unenumerated content; the named elements, limitations, steps, whole numbers and / or features are essential, but other unnamed elements, limitations, steps, whole numbers and / or features may be added and still form a construct within the scope of the claim.The specific modalities described herein may be more limited in the claims that use the closed transition phrases “consisting of” or “consisting essentially of” (or variations thereof, such as, for example, “consisting of,” “which consists of,” “consisting essentially of,” and “which consists essentially of”) instead of or as an amendment to “comprises.” When used in the claims, whether introduced or added by amendment, the closed transition phrase “consisting of” excludes any element, limitation, step, whole number, or feature not expressly mentioned in the claims.The closed transitional phrase “consisting essentially of” limits the scope of a claim to the expressly listed elements, limitations, steps, whole numbers, and / or features, and any other elements, limitations, steps, whole numbers, and / or features that do not materially affect the basic and novel characteristics of the claimed subject matter. Therefore, the meaning of the open transitional phrase “comprising” is defined as encompassing all specifically listed elements, limitations, steps, and / or features, as well as any additional unspecified optional elements.The meaning of the closed transitional phrase “consisting of” is defined as including only those elements, limitations, steps, whole numbers, and / or features specifically enumerated in the claim, whereas the meaning of the closed transitional phrase “consisting essentially of” is defined as including only those elements, limitations, steps, whole numbers, and / or features specifically enumerated in the claim and those elements, limitations, steps, whole numbers, and / or features that do not materially affect the basic and novel feature(s) of the claimed subject matter. Therefore, the open transitional phrase “comprising” (and equivalent open transitional phrases thereof) includes within its meaning, as a limiting case, the claimed subject matter specified by the closed transitional phrases “consisting of” or “consisting essentially of.”Thus, the modalities described in this document or claimed with the phrase comprising expressly and unequivocally provide a description, enablement, and support for the phrases consisting essentially of and consisting of.

[0110] Finally, all patents, patent publications, and other references cited and identified in this specification are hereby incorporated individually and expressly as references in their entirety for the purpose of describing and making known, for example, the compositions and methodologies described in such publications that could be used in connection with the present invention. These publications are provided solely for the purpose of informing the inventors about the invention prior to the filing date of this application. Nothing in this regard is construed, nor should it be construed, as an admission that the inventors do not have a right to prior ownership of such invention by virtue of a prior invention or for any other reason.All statements regarding the date or representation regarding the content of these documents are based on information available to the applicant and do not constitute any admission as to the accuracy of the dates or content of these documents.
