DETAILED DESCRIPTION OF THE INVENTION

Abbreviations and Definitions

[0036] Detailed descriptions of one or more embodiments are provided herein. It is to be understood, however, that the present invention can be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in any appropriate manner.

[0037] The singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification can mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.”

[0038] Wherever any of the phrases “for example,” “such as,” “including” and the like are used herein, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise. Similarly, “an example,” “exemplary” and the like are understood to be nonlimiting.

[0039] The term “substantially” allows for deviations from the descriptor that do not negatively impact the intended purpose. Descriptive terms are understood to be modified by the term “substantially” even if the word “substantially” is not explicitly recited. Therefore, for example, the phrase “wherein the lever extends vertically” means “wherein the lever extends substantially vertically” so long as a precise vertical arrangement is not necessary for the lever to perform its function.

[0040] The terms “comprising” and “including” and “having” and “involving” (and similarly “comprises,” “includes,” “has,” and “involves”) and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of “comprising” and is therefore interpreted to be an open term meaning “at least the following,” and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, “a process involving steps a, b, and c” means that the process includes at least steps a, b and c. Wherever the terms “a” or “an” are used, “one or more” is understood, unless such interpretation is nonsensical in context.

[0041] The term “about” can refer to the term approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).

[0042] For purposes of the present disclosure, it is noted that spatially relative terms, such as “up,” “down,” “right,” “left,” “beneath,” “below,” “lower,” “above,” “upper” and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over or rotated, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0043] The terms “subject” and “patient” as used herein can include all members of the animal kingdom including, but not limited to, mammals, animals (e.g., cats, dogs, horses, swine, etc.) and humans.

[0044] The term “tissue” as used herein can refer to any conglomeration of cells along with the extracellular matrix that work in concert to carry out a specific function. In embodiments, tissue includes nervous tissue, epithelial tissue, connective tissue, muscular tissue, or a combination thereof. Tissue can include dermis, epidermis, subcutaneous fat, fascia, or any combination thereof. In certain embodiments, the tissue may be injured or diseased. Injured or diseased tissue can refer to any tissue that is inflamed, dry, cancerous, wounded, abraded, eroded, burned, fractionated, or has been subjected to any other type of tissue injury or disease or combinations thereof. Injured or diseased tissue can refer to any of various skin conditions known in the art.

[0045] As used herein, the term “medical procedure” can refer to any course of action that is intended to achieve a desired result in the field of healthcare. In certain embodiments, medical procedures can include cancer treatment, cosmetic procedures, lesion treatment, burn care, or a combination thereof. Lesions can include cancerous or precancerous lesions. Non-limiting examples of pre-cancerous lesions include actinic keratosis, actinic cheilitis. Examples of cancerous lesions include but are not limited to melanoma, basal cell carcinoma, or squamous cell carcinoma. The term “medical procedure” can further encompass any procedure used in a research setting to study a health-related condition or to study or develop treatments for a health-related condition.

[0046] As used herein, the term “cosmetic procedure” can refer to any procedure intended to alter the physical appearance of a subject or a subject's tissue. In embodiments, a cosmetic procedure includes any aesthetic procedure. Cosmetic procedures can be non-invasive or minimally invasive procedures. Cosmetic procedures can include any procedure known by one of skill in art to be a cosmetic or aesthetic procedure. Exemplary cosmetic procedures include but are not limited to treatment of skin conditions, treatment of skin damage, cosmetic reconstruction, or a combination thereof. In embodiments, cosmetic procedures include chest wall reconstruction.

[0047] As used herein, the term major axis can refer to the widest span of an oval or ellipse.

[0048] As used herein, the term minor axis can refer to the narrowest span of an oval or ellipse.

[0049] Female to male transgender chest surgery is an increasingly common procedure in which the natal female breasts and nipples are altered to a more masculine appearance. Most commonly, mastectomies are performed, and the nipple areolar complex (NAC) is removed, reduced in size and shape, and repositioned on the chest wall in a more masculine location. The size of the male areola approximates a circle with about a 2.2 cm diameter. However, because of the underlying pectoralis muscle pull, the NAC should be sewn in as an oval with a horizontal diameter of about 2.5 cm and a vertical diameter of about 1.5 cm (Agarwal et al). Over time, the pull of the underlying pectoralis major muscle and tension across the closure rounds the oval out to a circle of 2.2 cm diameter, approximating the “ideal” cisgender male nipple.

[0050] No marking guide for either the a.) areola harvest or b.) areola inset exists in transgender female-to-male chest surgery or cisgender gynecomastia procedures.

[0051] In various exemplary embodiments, the presently disclosed surgical marking guide is configured to mark an area on a patient for resection of a graft material. The marking guide can be further configured to mark an area on a patient for implant of a graft material. The guide is configured to permit accurate placement by maintaining visualization of the underlying skin while in use. The presently disclosed surgical marking guide provides accurate and sterile resection and implant of graft material. In embodiments, the surgical marking guide is configured to mark a nipple areolar complex for resection as graft material, mark an area for implant of a nipple areolar complex graft material, or a combination thereof.

[0052] The presently disclosed surgical marking guide allows for replicable resizing of feminine-appearing nipples to a masculine size and shape, accurate marking of both the NAC harvest and inset, and can significantly reduce operative time.

[0053] Studies have shown that the ideal male nipple is a perfect circle and is about the size of a nickel. However, when a nipple is harvested for grafting as a circle, and sewn to the chest wall as a circle, the skin tension on the chest wall pulls the nipple into an oval with the long axis of the oval oriented vertically. This results in an unnatural nipple appearance, regardless of whether the patient is a man or woman, cis or trans.

[0054] Implanting the circular nipple graft as an oval, can overcome this problem. In various embodiments, utilizing the skin's natural tension across the incision, and with the right orientation of the oval, the body's natural healing processes and contracture of the graft permits the implanted nipple areolar graft complex to obtain a more circular appearance with eccentricity in a horizontal orientation. This produces a nipple that appears more masculine, leading to higher patient satisfaction and superior aesthetic results. In various embodiments, the presently disclosed surgical marking guide and methods of use allow for marking an ideally sized circular nipple graft, and facilitates marking of the oval for insetting the nipple graft on the chest wall in the proper orientation to achieve these results.

[0085] Another aspect of the present invention includes a method of using the surgical marking guide 100, 200, 300, 400 in accordance with any embodiment disclosed within this specification or otherwise apparent from the descriptions herein. In one embodiment, the method includes use of the surgical marking guide 100, 200, 300, 400 in the harvest and implant of a nipple areolar complex.

[0086] The method can include obtaining a surgical marking guide 100, 200, 300, 400 as described herein. In one embodiment, the first marking surface 110, 210, 310, 410 of the marking guide 100, 200, 300, 400 is depressed against a surgical area of a patient to denote a region to be harvested as a graft material. The graft material can then be removed from the surrounding tissue by surgical means. The second marking surface 120, 220, 320, 420 can then be depressed upon a second surgical area of the patient to denote a region for inset of the graft material. Following removal of the tissue within inset region, the graft material is implanted within the inset region.

[0087] In one embodiment, the graft material comprises a nipple areolar complex and the surgical procedure comprises female-to-male chest reconstruction surgery (see FIG. 8), reconstruction following cisgender gynecomastia, surgical construction of congenitally absent nipples, surgical reconstruction of absent nipples, or a combination thereof.

[0088] FIG. 8 provides a view of a schematic view of an exemplary female to male transgender chest reconstruction surgery. As can be seen, the surgical procedure can comprise the removal of a nipple areolar complex graft 710 from a patient 701. The procedure can further comprise an incision 706 along an inframammary fold and subsequent removal of the patient's breast tissue and any excess skin 707. Following removal, the incision 706 can be closed and the new site for the nipple areolar complex graft implantation 720 can be marked. After marking of the implant location, the nipple areolar complex graft 710 can be implanted in the appropriate location 720. As discussed above, the presently disclosed surgical marking guide 100, 200, 300, 400 can be utilized for marking the nipple areolar complex graft 710 for resection, marking of the implant location and orientation 720; confirmation of correct location or orientation of the nipple areolar complex graft 710, or a combination thereof.

[0089] FIG. 9A provides a top view of a surgical marking guide 400 under one embodiment being used to mark an area for implantation of a nipple areolar complex graft material. A practitioner's fingers 901 are shown gripping the surgical marking guide 400 and holding the guide in place over the site for implantation of the graft. The surgical incision 706 made to permit removal of breast tissue and excess skin can be seen extending across the surgical field of the patient 701.

[0090] As shown in FIG. 9A, in operation, the orienting extensions 450 are configured to assist the practitioner in properly orienting the surgical marking guide 400. In such embodiments, the practitioner can apply orienting marks along the exterior border of the surgical graft site, wherein each mark corresponds to an orientation extension 450 on the surgical marking guide 400. The practitioner can then place the surgical marking guide 400 on the implantation site, aligning the orientation extensions 450 with the orientation marks to ensure accurate placement of the surgical marking guide 400 and proper inset of the graft material.

[0091] FIG. 9B provides a view of a surgical filed of a patient 701 immediately following use of a surgical marking guide as shown in FIG. 9A for bilateral resection and implant of a nipple areolar complex graft material 701 during a female to male transgender chest surgery.

[0092] FIG. 10A shows a close-up view of a patient 701 immediately following use of a surgical marking guide under one embodiment for resection and implant of a nipple areolar complex graft material 710 during a female to male transgender chest surgery. The recently closed surgical incision site 706 is shown extending horizontally across the surgical field, below the implanted nipple areolar graft material 710. As can be seen, the newly implanted nipple areolar complex graft 710 can comprise a generally oval shape immediately following implantation.

[0093] FIG. 10B shows a close-up view if the patient 701 from FIG. 10A, but three months following the use of the presently disclosed surgical marking guide during a female to male transgender chest surgery. The surgical incision site 706 has healed significantly and the implanted nipple areolar complex graft 710 has developed the prototypical circular shape that is consistent with that desired during such a chest reconstruction surgery.

[0094] FIG. 11A provides a view of the chest of a patient 701 prior to a female to male transgender surgery under one embodiment. FIG. 11B shows a view of the FIG. 11A patient's chest three months following the use of one embodiment of the presently disclosed surgical marking guide to perform a female to male transgender chest surgery.

[0095] FIG. 12A provides a view of the chest of another patient 801 prior to a female to male transgender surgery, and FIG. 12B shows a schematic representation of the patient 801 from FIG. 12A at three months following the surgical procedure.

[0096] As can be seen in the FIG. 11 and FIG. 12 embodiments, the nipple areolar complex graft material 710, 810 assumes a generally circular, masculine shape and the patient's chest has an improved masculine appearance within at least three months following use of the presently disclosed surgical marking guide during a female to male transgender chest reconstruction surgery.

[0097] Alternate methods include marking a first surgical area comprising a cancerous or precancerous lesion for removal with the second marking surface followed by removal of the surgical area comprising the cancerous or precancerous lesion. The first marking surface can then be used to mark a second surgical area, wherein the second surgical area comprises a graft material. The graft material can then be removed and implanted within the first surgical area to replace the cancerous or precancerous tissue that was removed.
