[0026] FIG. 1 is a simplified top view of a perineum overlay device 100 in accordance with embodiments of the invention. In some embodiments, the device 100 is designed to assist in locating or identifying anatomical features within the perineum of a patient and/or needle insertion sites for targeting anatomical features within the perineum of a patient, to simplify A92.13-0084 (AMS-3725-PCT) -5 pelvic condition treatments. The pelvic condition treatments that may be simplified using the device 100 include treatments that are designed to alleviate pelvic floor muscle hypertonicity and/or spasm, which may be effective in treating other pelvic disorders rooted from pelvic floor neuromuscular abnormalities. Such treatments may involve the injection of drugs, such as botulinum toxin (Botox), recording electromyogram signals from muscles of the pelvic floor, electrically stimulating muscles of the pelvic floor, and/or implanting an electrode in muscles of the pelvic floor that may be used to perform an electrical stimulation therapy, for example. The device 100 may be useful in other pelvic condition treatments. [0027] In some embodiments, the device 100 includes a section of flexible material 102 that is configured to conform and cover a portion of the perineum of a patient. A plurality of markings, generally referred to as 104, are printed on a first side 106 of the section 102. Each of the markings 104 is configured to identify a location of an anatomical feature within the perineum, and/or a needle insertion site corresponding to a targeted anatomical feature within the perineum, when the section of flexible material 102 is positioned over the perineum of a patient. [0028] In some embodiments, the locations of the markings 104 on the section of flexible material 102 are determined based on a patient model, such as an average female patient. Devices 100 may be designed based on other patient models in order to accommodate a range of individuals. As a result, a device 100 may be selected for a patient such that the markings 104 align with the corresponding anatomical features of the patient, when the device 100 is placed over the perineum of an actual patient. [0029] Exemplary anatomical features of the perineum that may be identified or targeted by the markings 104 will be described with reference to FIG. 2, which illustrates a view of inferior tissue at different levels of a pelvic region, including the gluteus maximus 108, the levator ani 110 (which includes the iliococcygeus muscle), sacrotuberous ligament 112, ischial tuberosity 114, superficial transverse perineal muscle 116, pubococcygeus muscle 118, puborectalis muscle 120, and the perineal body 122. The epidermis 124, the coccyx 126, the urethra 128, the vagina 130, and the anus 132 are also shown in FIG. 2. [0030] Thus, in some embodiments, the device 100 includes an anatomical marking 104A corresponding to the urethra of a patient model, an anatomical marking 104B corresponding to the vagina of the patient model, an anatomical marking 104C corresponding to the anus of the A92.13-0084 (AMS-3725-PCT) -6 patient model, an anatomical marking 104D corresponding to the puborectalis muscle of the patient model, an anatomical marking 104E corresponding to the pubococcygeus muscle of the patient model, an anatomical marking 104F corresponding to the iliococcygeus muscle of the patient model, 104G corresponding to the perineal body of the patient model, and/or other muscle or anatomical feature beneath the perineum of the patient model. [0031] In some embodiments, the markings 104 comprise graphical markings that are used to identify anatomical features. Such graphical markings may comprise various shapes, lines, colors, shading, and other graphical features to identify the anatomical feature to which the markings 104 correspond. [0032] In some embodiments, the markings 104 include textual markings or labels that identify the anatomical feature to which they correspond. For instance, a marking 104 may include the name of the anatomical feature written out, or a reference number or character from which the corresponding anatomical feature may be identified using a look-up table, for example. [0033] In some embodiments, the markings 104 include openings in the section of flexible material 102. These openings allow the physician to observe the perineum of the patient through the section of flexible material 102. In some embodiments, the openings of the markings 104 are configured to be placed over the corresponding anatomical feature of the patient. [0034] In some embodiments, the perineal overlay device 100 is configured to be placed over the perineum of a patient, as shown in the simplified illustration of FIG. 3. In some embodiments, the device 100 is positioned over the perineum such that the markings 104 identifying anatomical features directly overlay the corresponding anatomical features (FIG. 2) of the patient. Thus, when the perineum overlay device 100 is properly positioned over the perineum of the patient, a marking 104A corresponding to the urethra of a patient overlays the urethra 128 of the patient, a marking 104B corresponding to the vagina should overlay the vagina 130 of the patient, a marking 104C corresponding to the anus of the patient should overlay the anus 132 of the patient, a marking 104D corresponding to the puborectalis muscle, should overlay the puborectalis muscle 210 of the patient, an anatomical marking 104E corresponding to the pubococcygeus muscle should overlay the pubococcygeus muscle 118 of the patient, an A92.13-0084 (AMS-3725-PCT) -7 anatomical marking 104F corresponding to the iliococcygeus muscle should overlay the iliococcygeus muscle (levator ani 110) of the patient, and so forth. [0035] In some embodiments, some of the markings 104 are configured as alignment markings to assist the physician in aligning the markings 104 of the perineal overlay device 100 to the corresponding anatomical features of the patient 134. The alignment markings 104 may include some of the markings 104 described above, such as the markings corresponding to the urethra (104A), the vagina (104B), and the anus (104C), for example. These markings may have openings through which the physician can locate the corresponding anatomical feature of the patient to assist in aligning the device 100. In some embodiments, a physician may mark a location on the epidermis of the patient corresponding to an anatomical feature of the patient 134, which may then be aligned to a marking 104 on the device 100 to assist in aligning the device 100 to the patient 134. [0036] In some embodiments, a back side 140 of the section of flexible material 102 comprises an adhesive layer 142, as illustrated in the cross-sectional view of the device 100 overlaying the perineum 144 of the patient 134 provided in FIG. 4. The adhesive layer 142 is preferably configured to bond to the epidermis 124 of the patient and prevent shifting of the device 100 relative to the perineum of the patient 144. In some embodiments, the adhesive layer 142 is located only at select portions of the section of flexible material 102, such as the shaded sections 146 illustrated in FIG. 1. Alternatively, the physician may apply a suitable adhesive to the epidermis 124 of the patient to adhere one or more portions of the material 102 to the patient. [0037] After one or more of the markings 104 have been aligned with the corresponding anatomical features of the patient 134, the device 100 may be used to assist the physician in performing a pelvic treatment configured to treat a pelvic condition of the patient, such as those mentioned above. In some embodiments, the pelvic treatment involves the insertion of a needle 150 into tissue 152 within the perineum 144 of the patient, as illustrated in FIG. 4. The needle 150 may be in the form of an electrode needle, an introducer needle, or a needle configured to inject a substance into the tissue 152. In some embodiments, the pelvic treatment involves the positioning of the needle 150 within a specific anatomical feature of the patient, such as a muscle within the perineum 144. In some embodiments, the perineum overlay device 100 is used to A92.13-0084 (AMS-3725-PCT) -8 assist in determining the location where the needle 150 is to be inserted in order to perform the desired pelvic treatment. [0038] In some embodiments, the physician may use the anatomical markings 104 to locate the desired anatomical feature of the patient and identify the location where the needle 150 is to be inserted. In some embodiments, the markings 104 include one or more needle insertion site markings 104N that identify specific locations where a needle 150 is to be inserted to perform a pelvic treatment. The physician identifies the needle insertion site marking 104N corresponding to the desired pelvic treatment to be performed, and inserts the appropriate needle 150 through the needle insertion marking 104N and performs the treatment using the needle 150, as shown in FIG. 4. [0039] In some embodiments, the pelvic treatment requires the needle 150 to be positioned at a certain depth in order to reach the targeted anatomical feature on which the pelvic treatment is to be performed. For instance, the anatomical feature may comprise a muscle within the perineum 144 of the patient 134 that is at a known depth within the tissue relative to the corresponding needle insertion site marking 104N when the device 104 is properly positioned over the perineum 144 of the patient. In some embodiments, the physician selects an appropriate length needle 150 that positions the distal end 154 at the desired depth within the tissue 152 of the patient. [0040] In some embodiments, the device 100 includes one or more needle stops 160, a cross sectional view of which is provided in FIG. 4. Each needle stop 160 is attached to the side 106 of the section of flexible material 102 where a pelvic treatment is to occur, and assists in controlling the depth at which the needle 150 is inserted into the patient. In some embodiments, the one or more needle stops 160 are positioned at needle insertion site markings 104N, as shown in FIG. 4, or operate as needle insertion site markings themselves. [0041] In some embodiments, the needle stop 160 comprises a body 162 having a cylindrical bore 164, through which the needle 150 may be inserted. In some embodiments, the needle stop 160 includes a shoulder portion 166 that is configured to engage a portion 168 of the needle 150 to prevent further movement of the needle 150 through the bore 164 and into the patient. Thus, the depth at which the needle 150 may be inserted into the patient 134 is limited by the needle stop 160. This allows for single sized needles to be used by the physician to perform pelvic A92.13-0084 (AMS-3725-PCT) -9 treatments while using needle stops 160 having various sizes to ensure that the needles are inserted in the patient at appropriate depths depending on the location of the needle insertion site. [0042] Some embodiments of the invention are directed to a method of using the perineal overlay device 100, formed in accordance with one or more embodiments described above, to perform a pelvic treatment on a patient 134. FIG. 5 is a flowchart illustrating a method of treating a pelvic condition of a patient in accordance with embodiments of the invention. At 170 of the method, one or more alignment markings on a first side 106 of a section of flexible material 102 of a perineal overlay device 100 are aligned with corresponding features on the perineum of a patient. As mentioned above, the alignment markings may comprise graphical or textual markings, or openings in the section of flexible material 102. These alignment markings may be aligned with anatomical features of the patient, such as the urethra 128, the vagina 130, the anus 132, and/or other anatomical features of the patient. Additionally, the alignment markings may be aligned with markings applied to the epidermis 124 of the patient. [0043] At 172, a second side 140 of the section of flexible material 102 is bonded to the perineum 144 of the patient 134 while the device 100 is properly aligned, as shown in FIG. 3. In some embodiments, one or more portions of the second side 140 of the section of flexible material 102, such as portions 146 (FIG. 1), include an adhesive layer 142 that is configured to bond the section of flexible material 102 to the skin 124 of the patient to bond the device 100 in the desired alignment with the perineum of the patient. In other embodiments, a physician may apply an adhesive to the epidermis 124 of the patient to bond the perineal overlay device 100 to the perineum 144 of the patient. [0044] At 174, a needle 150 is inserted through a needle insertion site marking 104N or an anatomical marking on the first side 106 of the section of flexible material 102 and into tissue 152 of the patient 134, as shown in FIG. 4. As discussed above, the needle insertion site marking 104N is aligned with an anatomical feature of the patient, such as a muscle within the perineum 144, that is targeted for a pelvic treatment. Alternatively, the physician may determine an appropriate location to insert the needle 150 based on the anatomical markings 104 provided on the section of flexible material 102, such as those described above. In some embodiments, a needle stop 160 is used to assist in the insertion of the needle 150 into the patient, as described above.
    A92.13-0084 (AMS-3725-PCT) -10 [0045] At 176, a pelvic treatment is performed on the patient 134 using the needle 150. Embodiments of the pelvic treatment include injecting a substance (e.g., Botox) into the targeted tissue 152, recording electromyogram signals produced by the targeted tissue 152, electrically stimulating the targeted tissue 152, and/or implanting an electrode in the targeted tissue 152. Other pelvic condition treatments may also be performed. [0046] Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
