CROSS-REFERENCE TO RELATED APPLICATION(S) 
       [0001]    The present application relates to U.S. Patent Application Ser. No. 61/874,686, filed Sep. 6, 2013, the entire disclosure of which is incorporated herein by reference. 
     
    
     FIELD OF THE DISCLOSURE 
       [0002]    The present disclosure relates to exemplary systems, devices, apparatus and methods for providing an endoscopic mucosal therapy, and in particular to exemplary systems, devices, apparatus and methods for treating mucosal diseases (including, e.g., especially mucosal diseases) of the esophagus and the gastrointestinal tract. Such exemplary systems, devices, apparatus and methods can be utilized for an endoscopic treatment of early mucosal cancer and pre-cancerous lesions of the esophagus and gastro-intestinal (GI) tract. 
       BACKGROUND INFORMATION 
       [0003]    Many diseases originate on superficial tissues such as the mucosal tissues of the gastrointestinal tract. These can include various cancers of the gastrointestinal tract which originate as precancerous mucosal lesions and later invade deeper tissue structures. One strategy for the treatment of these mucosal diseases is to damage the mucosal tissue to a depth sufficient to eliminate the disease, but not sufficiently deep to induce side effects which can include organ perforation or stricture. Such therapy is sometimes called an “ablation” therapy because the mucosal surface is “ablated”, or damaged. A damaged mucosal surface can regrew with a more limited disease extent, or without disease. 
         [0004]    The ablation therapy is common in the treatment of early-stage esophageal adenocarcinoma. A common approach is radio-frequency ablation. For example, an endoscopic device is placed adjacent to the mucosal lining of the esophagus. The device contains electrical conductors that provide a localized radio-frequency field which interacts with nearby tissue to heat and thereby affect tissue viability. Because of the radio-frequency field spatial confinement, the damage is limited to the tissues adjacent to the device. This allows mucosal tissues to be targeted while also providing some sparring of deeper tissues such as the submucosa or adventitia. Other methods to provide spatially limited damage, i.e., “ablation”, to the mucosa include laser therapy, photodynamic therapy, and cryotherapy. Multiple devices for delivering these energies to the mucosa have been proposed. 
         [0005]    One challenge associated with existing endoscopic mucosal therapy deployments can be that the depth of the therapy is not intrinsically limited to anatomical boundaries, but instead is typically induced to a fixed distance from the device at the time of therapy. In a radio-frequency ablation, for example, a fixed ablation depth is achieved, for example, 400 μm, which does not necessarily correlate to an anatomical landmark, for example, the muscularis mucosa. In addition, the physical thickness of the mucosa can vary significantly between patients and in response to disease state and applied force. For these reasons, among others, existing methods and system for providing an endoscopic mucosal therapy can require multiple treatments sessions to eliminate the lesion, or can be result in damage to tissue anatomical layers that are not intended to be targeted. 
         [0006]    An alternative strategy for delineating between the mucosal tissue to be damaged (“ablated”) and that to be sparred is based on differing mechanical properties of the tissue layers. Most gastrointestinal tissues can be arranged in layers. For example, in the esophagus, the most superficial (luminal) layer is the epithelium, followed by the lamina propria, the muscularis mucosa, the submucosa, and finally the muscularis externa (ME). The more superficial layers are not rigidly bound to the other ME layers. Instead, the inner layers can slide a finite distance, can buckle if the ME layers contracts, or can be lifted a finite distance from the ME. This mechanical feature can be used to define a depth boundary in a therapy. 
         [0007]    Endoscopic mucosal resection (EMR), for example, relies on the ability of the superficial mucosal layers to be lifted from the deeper layers by fluid injection. In EMR, a fluid such as saline can be injected into the submucosal space, lifting the mucosal surface away from the deeper structures. This lifted tissue is then mechanically resected and removed, and can be analyzed for pathology. EMR is therefore both a diagnostic and a localized therapy, and in the therapy the depth extend is defined in part by how the differing tissue layers are mechanically bound to the others. 
         [0008]    When applied as a therapy, EMR is generally used over limited regions. In many endoscopic mucosal therapies such as radio-frequency ablation, it is desired to destroy (“ablate”) large areas of the superficial mucosa. 
         [0009]    Accordingly, there is a need for system, device, apparatus and method that can address at least some of the above-described deficiencies, and apply therapies over large areas, and can target the extent of tissue destruction in part based on the mechanical properties of different anatomical tissue layers. Further, EMR resects tissue leaving some bleeding and scarring. There is a need for system, device, apparatus and method that can apply non-surgical (e.g., non-resection) intervention where the extent of tissue therapy is based in part on the mechanical properties of anatomical layers. 
       SUMMARY OF EXEMPLARY EMBODIMENTS 
       [0010]    Thus, to address at least such issues and/or deficiencies, exemplary embodiments of exemplary systems, devices, apparatus and methods can be provided for an endoscopic mucosal therapy, and in particular to exemplary systems, devices, apparatus and methods for treating mucosal diseases (including, e.g., especially mucosal diseases) of the esophagus and the gastrointestinal tract. 
         [0011]    For example, many of these tissues have unique mechanical properties that allow superficial layers to slide and lift over a limited extent relative to deeper tissues. The exemplary systems, devices, apparatus and methods described here can utilize this ability to, e.g., partially separate superficial layers from deeper layers to achieve a therapeutic effect that is largely confined to the superficial tissue. The exemplary systems, devices, apparatus and methods can be operated, for example, by extending a portion of mucosal tissue away from its underlying tissue structures, and applying a local energy, field, force, or other method to damage, destroy, or alter this extended tissue extent. By extending the tissue away from deeper structures, the therapy effect can be better confined to the superficial layers, and that confinement of therapeutic effect can, for example, be based in part on the mechanical properties of differing anatomical layers rather than on a fixed distance. 
         [0012]    The exemplary embodiments of exemplary systems, devices, apparatus and methods according to the present disclosure can differs from existing radio-frequency ablation devices and laser thermal therapy devices in that the shape or form of the mucosa is altered such that regions of mucosal tissue are displaced from underlying tissue structures. Further additional differences from an endoscopic mucosal resection can be that the therapeutic effect is not based on surgical excision of tissues but rather on applying a therapeutic effect to tissue in situ, such that that tissue can remain in place for a limited time after the exemplary procedure. 
         [0013]    Accordingly, an exemplary embodiment of exemplary systems, devices, apparatus and methods can be provided that can effect at least one first layer of at least one biological structure of an internal organ can be provided. For example, it is possible to utilize at least one structural arrangement which is configured to be inserted into or adjacent to the organ, and including at least one vacuum device which is configured to at least partially displaced the first layer from at least one second layer. The displacement of at least one portion of the first layer from the second layer can occur solely due to an application of suction by the at least vacuum device on the first layer. The displacement can further occur by an application of a force on the first layer. At least one structural further arrangement can also be used which is configured to damage, without removing, the displaced portion of the first layer. A displacement of adjacent portions of the first layer from the second layer can be performed in the organ by of a translation and/or a rotation of the device along a surface of the structure(s). 
         [0014]    In a further exemplary embodiment of the present disclosure, the further arrangement can causes the damage to the displaced portion(s) by providing (i) a photo-thermal heating, (ii) a conductive heating, (iii) irreversible electroporation, (iv) radio frequency heating, (v) photo dynamic therapy, and/or (vi) ultrasonic heating. The organ can be (i) esophagus, (ii) lung, and/or (iii) a gastrointestinal organ. One or more of the arrangements can be configured to be affixed to an end portion of an endoscope, to be conveyed through a port of an endoscope, or to be placed at the site without use of an endosope. The further arrangement can be further configured to damage the displaced portion(s) repeatedly more than once. The damage of the displaced portion can avoid an extensive damage of the second layer. For example, after the displaced portion is damaged, such displaced portion can be returned to be adjacent to its original position. 
         [0015]    According to yet another exemplary embodiment, the organ can be a luminal organ, and the device can cause a continuous damage to the displaced portion for at least 360°. The arrangement can be further configured to measure a temperature of the displaced portion(s). 
         [0016]    These and other objects, features and advantages of the present disclosure will become apparent upon reading the following detailed description of exemplary embodiments of the present disclosure, when taken in conjunction with the appended drawings and appended claims.

       [0035]    Throughout the drawings, the same reference numerals and characters, if any and unless otherwise stated, are used to denote like features, elements, components, or portions of the illustrated embodiments. Moreover, while the subject disclosure will now be described in detail with reference to the drawings, it is done so in connection with the illustrative embodiments.

       DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       [0036]    An exemplary layering architecture of a mucosal or other tissue is illustrated in  FIG. 1 . As shown therein, the luminal surface  107  is defined by the epithelium (EP)  101 . The deeper structures are in order of increasing depth from the luminal surface: the lamina propria (LP)  102 , the muscularis mucosa (MM)  103 , the submucosa (SM)  104 , the muscularis externa (ME)  105 , and the adventitia (AD)  106 . This exemplary arrangement of tissue layers corresponds to that of the normal human esophagus, and is illustrated to be used in connection with the descriptions of exemplary embodiments described hereafter. It should be understood that the exemplary embodiments of the present disclosure described herein can be applied to tissues of different architectural structures, anatomies, and/or locations. 
         [0037]    A cross-sectional view of a conventional radio-frequency therapy device  200  in operation is presented in  FIG. 2 . As shown in  FIG. 2 , the therapy device  200  is placed in contact with the mucosal tissue surface  201 . This device can be a paddle affixed to an endoscope, or a balloon-based therapy device. The device  200  defines a therapeutic field  202  from the device surface to a location  203  within the tissue. For the radio-frequency ablation, this therapeutic field  202  is radio-frequency excitation that ablates the tissue through thermal effects. The ablated or treated tissue can then be mechanically scraped from the organ wall, or can be left to be replaced during healing and new tissue growth. Because the anatomy is not known, the therapeutic depth can be located superficial to a specific anatomical layer or deeper than a specific anatomic layer. As a result, it is likely difficult to target anatomical layers using the conventional device  200 . This can lead to an insufficient treatment depth, or to over-treatment (treatment to a larger depth than is needed and or is safe) which can produce side-effects such as stricture or esophageal perforation. 
         [0038]      FIG. 3  shows exemplary cross-sectional views of a therapy device ( 300 , e.g., which can also include or be referred to a system and/or an apparatus) according to an exemplary embodiment of the present disclosure in an exemplary use thereof. The initial application of the exemplary device  300  is illustrated in section  300   a  of  FIG. 3 . For example, the exemplary device  300  can be placed in contact with the tissue surface  361 . The device can be configured to apply a therapy field  361  that is at least partially recessed into the exemplary device. As shown in section  300   b  of  FIG. 3 , via a mechanical, vacuum, or other procedure or configuration, the exemplary device  300  can deform the tissue such that superficial layers are brought into the recessed region of the device  301 . Here, the layers  370   a  and  370   b  are raised into the recessed region where the therapy field  310  is located. The therapy field can then be activated achieving local treatment that is at least partially confined to the tissue layers which are raised into the device. Deeper tissue structures  370   c  and  370   d  are at least partially sparred from damage. When the device  300  is removed, the tissue (including the treated tissue) can approximately return to its nominal shape and the treated tissue can, for example, become necrotic and be replaced by new tissue growth over time. 
         [0039]    Multiple exemplary methods, configurations, systems, apparatus, devices and/or designs can be provided for extending the mucosa above and away from deeper tissues, as is illustrated in  FIG. 3 . In one exemplary embodiment of the device/system/apparatus shown in  FIG. 4 , vacuum (negative) pressure can be used to pull the tissue into a shaped device  400  through a vacuum force  420 . The exemplary device  400  can optionally be configured to have regions of limited frictional force ( 403   a ,  403   b ) to allow mucosal tissue to slide laterally. These exemplary regions can be constructed for example by use of materials with reduced friction. such as, e.g., Teflon. The exemplary device  400  can further be configured to have tubing or other conduits  404   a ,  404   b  to apply a lubricating material, such as glycerol or water, to enhance tissue sliding. This can be achieved, for example, through a port  404   c  on the device  400 . A lubricant dispenser  411  can be located at a separate location. A vacuum or suction pump  410  can also be located at a location separate from the exemplary therapy device  400 . Vacuum can be transmitted to the device  400  through tubing and/or other conduits  405   a ,  405   b , and interface with the tissue through a vacuum port  405   c.    
         [0040]    Multiple methods, configuration, systems, apparatus, devices and/or designs can be provided for inducing a therapeutic effect on the mucosal tissue. In one exemplary embodiment of the device/system/apparatus shown in  FIG. 5 , the device  500  can include two electrodes  501   a ,  501   b  for performing an irreversible electroporation (IRE) on the tissue. For example, high-voltage pulses are used to damage the tissue located between the electrodes  501   a ,  501   b  through in part non thermal effects. IRE can have the advantage that tissue healing is generally improved after treatment and scarring is minimized relative to thermal damage. 
         [0041]    IRE is a mechanism that is different from Radio-Frequency Ablation. For example, in IRE, the tissue damage does not result from thermal injury, and instead from electric-field induced pores in the cell membranes. For example, as shown in  FIG. 5 , a voltage field can be generated between electrodes  501   a ,  501   b  with a magnitude between about 100 and 10,000 kV/cm, and can be delivered as a sequence of pulses with each pulse of duration 1 microsecond to 10 ms and delivered at a repetition frequency of 1 Hz to 100 kHZ. The pulse repetition frequency can be reduced as needed to limit heating effects. Exemplary repetition rates of 1-10 Hz can be common, and higher repetition rates can be supported in this exemplary device Such exemplary device  500  can also be configured to cool the tissue to avoid thermal damage by inclusion of for example a thermoelectric cooler or circulating chilled liquid. This cooling can facilitate a use of higher repetition rates. In this exemplary device, the pulses can be delivered continuously and tissue heating within the therapy region can be reduced by the combination of active cooling and translation of the device. 
         [0042]    Further multiple methods, configuration, systems, apparatus, devices and/or designs can be provided for applying this therapy over a large field. In on one exemplary embodiment of the device/system/apparatus shown in  FIG. 6 , the device  600  can be configured, structured and/or sized to allow it to slide along the mucosal surface  601  such that mucosal superficial tissues are pulled into the therapy device along the sliding path and a large area or long stripe  602  of therapeutic effect is induced. In certain exemplary endoscope configurations according to various exemplary embodiments of the present disclosure, this exemplary device  600  can, for example, be attached to the endoscope and can be pulled proximally by the endoscopist through a proximal retraction of the endoscope. When the exemplary device  600  is configured to provide a non-destructive therapeutic effect that does not immediately remove tissue, an exemplary advantage of this exemplary therapy device  600  is that the same tissue locations can be treated repeatedly without significantly extending the therapy depth. For example, if IRE is used, re-treatment of the same tissue will reapply fields to already treated areas and potentially increase therapeutic efficacy of that tissue but it will not significantly extend therapeutic effect deeper to tissue that should be protected. This re-treatment can facilitate large areas of the esophagus to be treated sequentially using for example multiple treatment stripes  602  that can be overlapped to facilitate and/or ensure full coverage of the therapy with a reduced risk of over-treatment. To improve the uniformity of treatment, the exemplary device can be configured and/or structured so as to be retracted at, e.g., a nearly constant velocity by use of a linear motorized stage. 
       Further Exemplary Embodiments for Deforming the Mucosal Tissue 
       [0043]    According to other exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs of the present disclosure shown in  FIG. 7 , mechanical rotors or roller  701   a ,  701   b  can be used to buckle the mucosa through lateral forces. These rotors/rollers  701   a ,  701   b  can be configured to contact tissue and push it toward a centerline  705  of the exemplary therapy device  700 . This can be done, for example, through spikes  702  on the rotors/rollers  701   a ,  701   b , through a surface preparation and/or suction ports  703 , among others. This exemplary configuration can be combined with vacuum configurations and/or procedures described above in connection with the exemplary embodiment shown in  FIG. 4 . Further, according to another exemplary embodiment, a single rotor/roller can be used, for example, the rotor/roller  701   b , and instead of the second rotor  701   a . Thus, the exemplary device  700  can be configured to have increased tissue friction such that the lateral force provided by the first rotor/roller  701   b  would buckle tissue into the cavity of the exemplary therapy device  700 . The area configured to have increased tissue friction can be implemented, for example, by surface texturing, by vacuum/suction ports, or by extended spikes similar to those of the spikes  702 . 
         [0044]    According to another exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs of the present disclosure shown in  FIG. 8 , the device  800  can be configured to affix to the mucosal tissue in, for example, three lines  801   a ,  801   b ,  801   c , and can be configured, structured and/or sized to be largely flat to align each of these lines  801   a ,  801   b ,  801   c  to a flat mucosa surface  815 . The exemplary device  800  can be configured to fold such that the tissue affixed to the line  801   b  is raised, and the tissue affixed to the lines  801   a ,  801   c  is laterally moved toward the device center, thus providing a bucking force bringing superficial tissues  809  above deeper tissues  802 . The affixing regions or lines  801   a ,  801   b ,  801   c  of the device  800  can operate by vacuum, by adhesives, or by protruding needles/hooks. 
         [0045]    In still another exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs according to the present disclosure shown in  FIG. 9 , a tape  976  comprising three adhesive lines  905   a ,  905   b ,  905   c  can be affixed to a tissue surface  977  using, for example, adhesives or mechanical needles/hoods. This tape  976  can be configured or provided with rails  902   a ,  902   b ,  902   c  that can interface with mechanical mounts  910   a ,  910   b ,  910   c  on the endoscopic device  900 , as shown in a configuration  901   a . The exemplary endoscopic device  900  can then be configured to collapse the tissue by movement of the rails  902   a ,  902   b ,  902   c  to achieve the mucosal tissue separation, as provided in a configuration  901   b . In this exemplary design, the long regions can be treated by pulling the device backward along the respective rail  902   a ,  902   b ,  902   c.    
       Further Embodiments 
     For Treatment of Deformed Tissues 
       [0046]    The exemplary embodiments of systems, devices, apparatus and methods according to the present disclosure can be provided for inducing a therapeutic effect on tissue within the deforming devices described previously. In one exemplary embodiment shown in  FIG. 6 , IRE can be used to alter cell viability, as described herein. For example, using a similar exemplary design as understood by those having ordinary skill in the art after reviewing the present disclosure, RF ablation of the tissue can be achieved by adjusting the electrical excitation frequency and amplitude. 
         [0047]    According to yet further exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs according to the present disclosure shown in  FIG. 10 , light or other electro-magnetic radiation can be delivered locally to the a treatment volume  1007 . Such light or radiation delivery can be achieved, for example, by optical waveguides  1002  that can convey light energy or other radiation  1008  from the console (not shown) to the exemplary device  1000 . Multiple optical waveguides can be used to achieve a more uniform light dose to the treatment volume. Such light or radiation light  1008  can be propagated into the mucosal tissue, and its absorption by mucosal tissue can lead to localized heating and thermal damage. For example, light or other radiation with wavelengths between about 1400 nm and 2300 nm can preferably be used to thermally heat tissue. Alternatively, light or other radiation can be used with exemplary wavelengths matched to blood absorption to target blood vessels for therapeutic effect also. The exemplary device  1000  can be specifically configured to prevent light leakage to deeper tissues by adjusting the optical properties of the device and by choosing wavelengths with limited penetration depths in tissue. For example, light/radiation wavelengths that have higher water absorption will propagate shorter distances in tissue and the resultant heating would remain more confined. The light/radiation interface to the treatment volume  1007  can optionally include a diffuser  1009  to spatially disperse density of the light/radiation energy  1008  before entering the tissue. 
         [0048]    In still further exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs according to the present disclosure shown in  FIG. 11 , heaters  1101   a ,  1101   b , such as, e.g., resistive electrical heaters, can be included into or be connected to the exemplary device  1100  to heat a treatment volume  1102  locally. Alternatively, these heaters  1101   a ,  1101   b  can be replaced with coolers, such as, e.g., thermoelectric coolers to cool tissue. Temperature sensors  1103   a ,  1103   b ,  1103   c  can be incorporated into or connected to the device  1100  to monitor the tissue temperature. An illustration of another exemplary embodiment of the configuration, system, apparatus, device and/or designs according to the present disclosure is shown in  FIG. 16 . In this illustration, e.g., an assembled device  1600   a  is provided alongside its exploded view  1600   b . The exemplary device illustrated in  FIG. 16  can include a center shaft  1610  that can be hollow, and can conveys a vacuum pressure and houses electrical wires, as well as provided mechanical interface to the console. A first and second piece  1620   a  can support the organ, and can optionally provide heat sinking or active cooling. A piece  1640  can be heated with integrated heaters (not shown) to a high temperature, for example, 90 degrees Celsius. Two thermal insulating pieces  1630   a ,  1630   b  separate the heat sink pieces  1620   a ,  1620   b  from the heated piece  1640 . These insulating pieces  1630   a ,  1630   b  can be made form a plastic such as Teflon. The heated piece  1640  can include radial holes  1641  to convey vacuum pressure, and the shaft  1610  can include holes  1611  to convey vacuum pressure. When assembled, a grove is formed within which therapy can be performed, as shown in  FIG. 17 . The grove can be formed outside the outer diameter of the heated piece  1740  and can be, for example, between about 0.5 mm to 2 mm deep and 0.5 mm to 2 mm wide (or possibly 1.5 mm deep 1.5 mm wide). 
         [0049]    According to other exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs of the present disclosure illustrated in  FIG. 12 , light emitters  1207 ,  1209  analogous or similar to those shown in  FIG. 10  located within or connected to the exemplary device  1200  can be used to initiate photodynamic therapy or photoactivatable therapy within the treatment volume  1207  using a photosensitizer drug that was previously delivered to the tissue either topically or systemically. Light or other radiation delivery can be performed using optical waveguides  1202 . 
         [0050]    In still other exemplary embodiments of methods, configurations, systems, apparatus, devices and/or designs according to the present disclosure illustrated in  FIG. 13 , ultrasonic transducers  1301   a ,  1301   b ,  1301   c  located within or connected to the exemplary device  1300  can be used to provide ultrasonic heating or ultrasonic damage to tissue  1302 . Using such ultrasonic transducers  1301   a ,  1301   b ,  1301   c  can be used to form an ultrasonic field  1303  in the tissue  1302 . 
       EMBODIMENT 
     For Integration with Endoscopes and Large Area Treatment 
       [0051]    Various exemplary methods or devices to endoscopically deploy these exemplary therapy devices can be used. According to exemplary embodiments of the configurations, systems, apparatus, devices and/or designs of the present disclosure illustrated in  FIG. 14 , the therapy device  1400  can be affixed or otherwise connected to an endoscope  1401  using a mounting  1402 , and can hang as a paddle that occupies a portion of the endoscopes&#39; circumferential view, for example 90 degrees. This exemplary paddle can extend into the endoscope&#39;s imaging field, as shown in  FIG. 14 , such that the treated tissue can be visualized, or can be drawn proximally to move it outside the imaging field, or alternatively can be designed or configured to move dynamically into and out of the imaging field, as needed. 
         [0052]    In another exemplary embodiment of the present disclosure, the exemplary therapy device can be configured to alter the treated tissue such that treated regions can be visually or endoscopically differentiated from untreated regions. For some exemplary methods of therapy, such as thermal injury, this marking of the treated tissue can be related to the therapeutic effect directly. Alternatively, a more limited thermal injury can be induced by light/radiation and/or by the heaters to mark the treatment region or to mark the borders of treated regions. For example, in the exemplary device/system/apparatus shown in  FIG. 5 , resistive heaters  1101   a ,  1101   b —as shown in  FIG. 11 —can be included to induce visible burn marks of the treated tissue area, e.g., to thermally mark the treatment region. Other marking methods include injection or adherence of ink or dye into or onto the tissue, or induction of visible marks from cutting, wounding, needle puncturing the tissue. Within the context of IRE, for example, ink could be moved into the tissue through the IRE process allowing areas treated with IRE to be marked. 
         [0053]    In a further exemplary embodiment of the present disclosure, the device/system/apparatus can be translated along the tissue to achieve larger areas—as depicted in  FIG. 6 . The exemplary device can be configured to monitor this displacement such that feedback can be given to the treatment personnel or directly to the device to control the application of the therapy, i.e., to stop treatment once the sliding motion has stopped and to resume once the sliding motion resumes, or to adjust the dosimetry based on the sliding velocity of the device. This exemplary monitoring can be performed using, for example, gyroscopes, endoscopic camera sensors, RF positional sensors, and/or sensors located with the device that can read out, for example, the treated tissue temperature. In addition, exemplary motorized mechanisms for moving the device in the treatment direction can be used such that at least nearly or possibly exactly constant velocity can be achieved. 
         [0054]    In yet another exemplary embodiment of the present disclosure, the exemplary device/system/apparatus can be designed and/or configured to treat simultaneously approximately 360 degrees of a luminal organ mucosa, as depicted in  FIG. 15 . As shown in  FIG. 15 , an exemplary device  1500  provided for deforming the tissue can have a circumferential design  1501  that can treat an area for 360 degrees by providing an appropriate therapy fields  1502 ,  1504 , and for a corresponding cross-section  1503  associated with the design  1501 . Exemplary designs and/or configurations achieving treatment less than 360 degrees can also be constructed. 
         [0055]    According to yet a further exemplary embodiment of the present disclosure, the exemplary device can be configured to include sensing, imaging and/or spectroscopy such that properties of the displaced tissue can be measured to determine in real time if treatment should be applied. This diagnostic for sensing, imaging, or spectroscopy arrangements can include, for example, optical coherence tomography imaging, camera imaging, light absorption or reflection spectroscopy, confocal microscopy, or Raman spectroscopy. 
         [0056]    In yet another exemplary embodiment of the present disclosure, the exemplary device/system/apparatus can include multiple recessed portions  310 , as shown in  FIG. 3 , which can be positioned along the device. For example, during a translation or rotation of the exemplary device/system/apparatus, a tissue portion can be first treated by the first recessed portion, and later re-treated by the second recessed portion. 
         [0057]    According to still another exemplary embodiment of the present disclosure, the delivery of energy to and/or by the exemplary device/system/apparatus can be facilitated in a continuous wave operational mode, and/or can be pulsed. For example, light (or other electromagnetic radiation) provided by the diffuser  1009  shown in  FIG. 10  can be pulsed at a repetition rate, for example, in a range of between about 0.1 Hz and 1 kHZ, as well as outside such range. 
         [0058]    In yet another exemplary embodiment of the present disclosure, the device/system/apparatus can be configured and/or structured to provide heat sinking from regions adjacent to the energy delivery, for example the regions  403   a ,  403   b  can be constructed substantially from metal such that the portions of tissue adjacent to these regions remain at lower temperatures. These exemplary regions  403   a ,  403   b  can also be actively cooled by for example a thermoelectric cooler or circulating chilled liquid within the device.
