The present disclosure relates generally to wearable harnesses, and, more specifically, wearable harnesses for securing and positioning an ultrasound device on a subject.
The nervous system is the major system that controls, regulates, and communicates between the body and the brain. Bioelectronic medicine is based on the idea that stimulating a nerve can affect biological functions. More and more medical devices applied to nerves are emerging as treatment for diseases, from regulating blood glucose levels to curbing pain, and even treating inflammatory disease such as rheumatoid arthritis, etc. Bioelectronic biomedicine technologies include anything from electrical signal to electro-magnetic fields to even ultrasound, and there has been development of both invasive implantable devices that are wrapped around a nerve or non-invasive stimulation such as cochlear and nerve stimulation at the surface of the skin. More recently, Cotero et al. showed that suborgan non-invasive low-intensity ultrasound can alleviate cytokine production and even hyperglycemia in a model of endotoxin-induced hyperglycemia and cytokine production. Furthermore, Huerta et al. showed that focused ultrasound can alleviate liver inflammation and reduce fat accumulation in an obese pre-clinical model. The results were comparable with traditionally invasive vagus nerve stimulation (VNS) devices that have been shown to induce a similar response, suggesting the possibility that a non-invasive approach via ultrasound can have a similar clinical effect as the more invasive approaching of directly stimulating the relevant nerve via implantable electrodes or cuffs.
Development of invasive electrical stimulation devices to treat chronic diseases is ongoing.
With respect to inflammatory diseases, the cholinergic anti-inflammatory pathway is known to modulate the mammalian immune response. The parasympathetic vagus nerve can transmit signals from the brain to the adrenergic splenic nerve, which interacts with splenic immune cells to modulate the immune system. The splanchnic sympathetic nerves synapse at the celiac-superior mesenteric plexus ganglion with the splenic nerve. Specifically, stimulation of the splenic nerve releases norepinephrine which stimulates splenic T cells that can then subsequently signal to the cytokine producing macrophages to reduce pro-inflammatory cytokine production. VNS has been shown to reduce production of cytokines like TNF-α and other interleukines associated with inflammatory diseases like rheumatoid arthritis, Crohn's disease, chronic kidney disease, and psoriasis. Furthermore, ultrasound stimulation has shown to be able to induce similar electrical activity for treatment of peripheral neuropathic disease in the clinic.
With respect to kidney/organ rejection/organ transplant, every 10 minutes, a patient (e.g., human or subject) is added to the national kidney transplant waiting list. In 2019, 91,834 kidneys were transplanted worldwide, costing $40.6B. In 2018, 20,000 kidneys were transplanted in the USA, meeting 20% of the US demand alone. Kidney transplantation is the only curative treatment for patients with end-stage renal disease who have a 70% 5-year mortality on dialysis. End-stage renal disease patients often require dialysis three times a week at a medical center, considerably reducing their quality of life. Global Burden of Disease study attributes 2.17% of deaths every year and 1.47% of disability-adjusted life years (DALYs) to chronic kidney disease. Unfortunately, up to 30% of people who receive a kidney transplant experience some degree of rejection, and this number has not been significantly changed in the past 40 years. Most rejections occur within six months after transplantation but can occur at any time, even years later. Prompt treatment can reverse the rejection in most cases and prevent further organ damage, but current treatments are mostly anti-inflammatory drugs and immunosuppressant drugs that have undesirable side effects, are hard to personalize, and are not ideal for long-term use.
In addition, there are studies showing that kidney transplant patients have elevated cytokine levels related to a systemic inflammatory response to the foreign organ, and that this is an underlying cause of kidney rejection.
Noninvasive ultrasound (US) stimulation targeting the spleen has been explored as a safe and effective alternative to invasive or systemic anti-inflammatory treatment. US stimulation targets the cholinergic anti-inflammatory pathway consisting of the vagus nerve to spleen circuit. This treatment was shown to have protective and therapeutic effects a K/BxN serum-transferred model of inflammatory arthritis, a rheumatoid arthritis (RA) mouse model, both when it was applied before or at the beginning of the disease. Single-cell RNA sequencing revealed that in T and B-cells, certain genes are upregulated in arthritis mice after receiving US treatment. Those genes included transcription factors c-Jun and JunB. C-Jun and JunB can form dimers, thus forming the transcription factor AP-1, which induces the transcription of pro-inflammatory genes. Further, both B and T-cells increased the transcription of genes involved in microtubule formation (like Ssh2) and crosslinking upon US treatment. This suggests that alterations in the cytoskeleton could alter the polarization or migration of lymphocytes, so that immune cell infiltration and inflammation are reduced. This is supported by the finding that upon vagus nerve stimulation, B cells showed reduced antibody production migration, which led them to aggregate in the marginal zone of the spleen. This demonstrates that the anti-inflammatory pathway regulates immune cell migration. Further, splenic US treatment of rats with intra-abdominal sepsis decreased TNF-α and MCP-1 levels.
In mice exposed to US before renal ischemia, the treatment protected kidney function and morphology, mediated by CD4+ T-cells. T-cell dependency of this effect was confirmed by using both an α7nAChR agonist and antagonist as well as α7nAChR deficient mice, which did not show the protective effect. This study identified the cholinergic anti-inflammatory pathway as an essential mediator of the anti-inflammatory effect of ultrasound, possibly by interacting with the splenic nerve, as it was previously shown to be the case in sepsis. The isolation and transfer of splenocytes from ultrasound treated mice into naïve mice alone had a protective effect on the kidney during IRI and CLP-induced sepsis, suggesting that ultrasound treatment may have changed the phenotype of these cells. Further, it has been demonstrated that this effect depends on the splenic nerve, as the deleterious effect of a splenectomy was also achieved by splenic denervation alone. This supports the findings that suggest that the spleen is involved in modulating inflammation during kidney injury mediated by the splenic nerve.
The α7 nicotinic acetylcholine receptor belongs to a family of ion channel receptors. Various types of immune cells, like B-cells, T-cells, microglia, monocytes and macrophages or dendritic cells, express the α7 nicotinic acetylcholine receptor and therefore respond to nicotine. Acetylcholine binding to α7nAChR triggers Ca2+ and sodium influx, which leads to neurotransmitter release in neuronal cells. In non-neuronal cells, Ca2+ influx causes calcium to be released from stores. In addition, kinases and phosphatases are activated, which results in signaling cascades that are independent from ion flux. For example, α7nAChR activation can inhibit TLR3/4/9 signaling, which promote the secretion of pro-inflammatory cytokines. In macrophages, the receptor can recruit Jak2, which induces the phosphorylation and activation of STAT3. This pathway is associated with the production of anti-inflammatory mediators. Downstream, it prevents the activation of the pro-inflammatory NF-kB pathway, which triggers pro-inflammatory cytokine production. Further, p38 MAP-kinase activation is inhibited, which prevents the release of pro-inflammatory cytokines like TNFa. In T-cells, it was suggested that the expression of α7nAChR is up-regulated during immune activation. Treatment with nicotine was shown to reduce T cell proliferation and the release of pro-inflammatory Th1 (TNF, IFN-y) and Th17 (IL-17, IL-17FIL-21, IL-22) cytokines, while anti-inflammatory IL-4 levels were increased. The activation of the receptor promoted a shift from Th1 to Th2 cells. NF-kB activation and IL-2 production were reduced after treatment. These effects were sufficient to reduce experimental autoimmune encephalomyelitis severity as well as immune cell infiltration and demyelination.
Further, US treatment inhibited the recruitment of neutrophils and myeloid cells into the kidney during renal ischemia. Macrophages play a key role in inflammation by producing cytokines. Therefore, modulating their activity may be a promising approach to treat or prevent inflammation in acute kidney rejection (AKI). Adrenergic stimulation was shown to inhibit the secretion of pro-inflammatory cytokines like TNF-a or IL-6 by splenic macrophages in a sepsis mouse model through an up-regulation of IL-10. This process is thought to be mediated by protein kinase A. The same effect was observed in an endotoxemia model, where vagus nerve stimulation reduced TNF production by macrophages in the spleen, while α7 KO abolished this effect. Modulation of splenic macrophage behavior in inflammation depends on the cholinergic anti-inflammatory pathway specifically through a preganglionic, which originates in the dorsal motor nucleus of the vagus nerve, and a second postganglionic, originating in the celiac-superior mesenteric plexus, and projecting in the splenic nerve. Interestingly, the immunomodulary properties of splenic nerve stimulation seem to be translatable to other animal models and even humans. A study using pigs as a model for human splenic innervation demonstrated that splenic nerve stimulation protects the animals from cardiovascular damage and reduces cytokine production upon LPS exposure. In a rodent endotoxemia model, pro-inflammatory cytokines TNF, IL-6, IFN-y, IL-1β, IL-1a and IL-12 were reduced in splenic lysates after splenic ultrasound. A first study compared the effects of US treatment on healthy individuals and five RA patients. US treatment of the spleen of healthy individuals for only three minutes was sufficient to reduce TNF production in the blood when it was exposed to LPS ex vivo. Daily splenic US treatment of RA patients resulted in the reduction of mRNA levels of pro-inflammatory cytokines such as IL-1β and IL-8 by monocytes. In CD8+ T-cells, IFN-y transcription was inhibited. Apart from cytokine expression, cytokine receptors like those for TNF, IL-6, IL-17, IL-13 and IFN-y, were also down-regulated in monocytes. Further, pro-inflammatory pathways resulting in IL-6 or TNF production, like the NF-kB pathway, were inhibited. Pathways promoting monocyte migration were also downregulated, while the adaptive immune response and the circulating immune cell composition remained unchanged. This suggests that the treatment is safe and does not induce overall immune suppression. Intriguingly, splenic US is also tested as a COVID-19 treatment to decrease inflammation and reduce the length of hospitalization. A pilot clinical trial is set out to determine whether the US has a beneficial effect in severe COVID-19 infections (Trial number: NCT04803409). This may be a promising approach considering vagus nerve stimulation in an acute respiratory distress syndrome (ARDS) model decreased CXCL9 mRNA levels and the secretion of pro-inflammatory cytokines TNF-a and IL-1β while increasing IL-10 levels. Further, the treatment seemed to switch macrophage polarization from a pro-inflammatory M1 to an anti-inflammatory M2 phenotype.
Conventional ultrasound systems comprise multiple components, including—but not limited to—a transducer to direct ultrasonic waves into a subject's body, a handle or wand attached to the transducer, and a display screen. These ultrasound systems require a medical professional to operate and may utilize a conductive gel to fill air gaps between the transducer and the subject's body. In conventional ultrasound systems, the medical professional first applies the conductive gel to the subject's body, then holds the transducer in contact with the subject's body by continuously applying pressure through the handle or wand. The images produced are displayed in real time on the display screen. In order to position the transducer accurately, the medical professional moves the transducer across the subject's body until a target feature appears on the display screen. External measurement tools may sometimes be necessary to position the transducer accurately on the subject's body.
In some aspects, provided are wearable harnesses for securing and positioning an ultrasound transducer on a subject's body. The wearable harnesses provided herein can include two adjustable shoulder straps, an adjustable waist strap, a pocket for holding a power pack, and a securing portion for holding the transducer. In some embodiments, the pocket for holding the transducer is positioned over the subject's spleen.
The conventional ultrasound systems described above are typically used for medical imaging. In recent years, some ultrasound systems have additionally been modified for immunomodulation. During immunomodulation, the ultrasonic waves emitted by these ultrasound systems stimulate nerves, such as the splenic nerve, into modulating the immune system. Ultrasound immunomodulation may be desirable over other immunomodulation treatments because it is non-invasive and does not require drugs to modulate immune pathways.
Like conventional imaging ultrasound systems, the transducers of immunomodulatory ultrasound systems are typically positioned and operated by a medical professional during treatment. However, many subjects may desire to undergo at-home ultrasound treatment without requiring the presence of a medical professional for every treatment.
Accordingly, in certain aspects, the harnesses (e.g., garment or back brace) provided herein allow a subject to consistently position and operate the transducer over a target organ or nerve, such as the splenic nerve, without requiring the presence of a medical professional. Unlike the conventional handheld transducers described above, the transducers described herein are attached to a wearable harness that is fastened to a subject's body. The transducer is placed on the wearable harness with a securing portion/mechanism and positioned over the subject spleen, which contains the splenic nerve, by a medical professional. A separate pocket of the wearable harness holds a power pack for the transducer. Additionally, the wearable harness includes adjustable shoulder and waist straps so that a medical professional can adjust the harness to fit the subject's body and secure the transducer over the subject's spleen. In some embodiments, the harnesses described herein may be configured to position an ultrasonic transducer over a liver (sympathetic fibers from the celiac plexus and parasympathetic fibers from the anterior and posterior vagal trunks) or another organ or nerve. In some embodiments, a positioning grid may be provided on the adjustable straps and/or the transducer securing portion to assist in the positioning of the transducer. Once the straps are adjusted, the transducer will be positioned in the same location above the subject's spleen every time the harness is worn. Thus, the subject can wear, activate, and remove the harness without requiring a medical professional to readjust the harness before every ultrasound treatment. This enables the subject to receive at-home ultrasound treatment without the presence of a medical professional.
In some embodiments, the wearable harness may be in the form of a belt, vest, or patch, that allows for consistent stimulation of the target organ.
In some embodiments, the wearable harness stimulates the splenic nerve (by directly targeting the spleen) to reduce inflammatory markers in the body such as, but not limited to, TNF-alpha, IL6.
The wearable harness may be configured and used to stimulate any other nerve or organ to modulate physiological function. Advantageously, no medical professional is needed, and the ultrasound device can be worn directly on the skin, while the user goes about their normal daily activities.
In some embodiments, provided is a system for securing an ultrasound transducer over a spleen of a subject, the system comprising: a harness comprising: a front portion configured to hold a power pack; a rear portion connected to the front portion by a first shoulder strap and a second shoulder strap; an adjustable waist strap configured to wrap around a subject's waist and connect the front portion and the rear portion; and a transducer securing portion located on the adjustable waist strap and configured to be positioned over a spleen of a subject, wherein the transducer securing portion comprises a two-dimensional scale; and a treatment unit comprising: an ultrasound transducer configured to couple to the transducer securing portion of the harness; and a mechanical lens positioned between the ultrasound transducer and the subject, the mechanical lens comprising a plurality of concentric rings and configured to adjust ultrasonic waves emitted by the ultrasound transducer.
In some embodiments, provided a harness for positioning an ultrasound transducer to a subject, the harness comprising: a front portion configured to hold a power pack; a rear portion connected to the front portion by a first shoulder strap and a second shoulder strap; an adjustable waist strap configured to wrap around a subject's waist and connect the front portion and the rear portion; and a transducer securing portion located on the adjustable waist strap and configured to be positioned over a spleen of a subject, wherein the transducer securing portion comprises a two-dimensional scale.
In some embodiments, provided is a treatment unit comprising: an ultrasound transducer; and a mechanical lens comprising a plurality of concentric rings and configured to adjust ultrasonic waves emitted by the ultrasound transducer.
In some embodiments, provided is a system for securing an ultrasound transducer over a spleen of a subject, the system comprising: a harness comprising: a front portion configured to hold a power pack; a rear portion connected to the front portion by a first shoulder strap and a second shoulder strap; an adjustable waist strap configured to wrap around a subject's waist and connect the front portion and the rear portion; and a transducer securing portion located on the adjustable waist strap and configured to be positioned over a spleen of a subject, wherein the transducer securing portion comprises a two-dimensional scale, and an ultrasound transducer configured to couple to the transducer securing portion of the harness.
In some embodiments, provided is a harness for positioning an ultrasound transducer to a subject, the harness comprising: a transducer securing portion configured to receive an ultrasound transducer and secure the ultrasound transducer in a first location directly over a spleen of a subject.
In some embodiments, provided is a method of using a harness for positioning an ultrasound transducer to a subject, the method comprising: securing a treatment unit to a transducer securing portion of a harness; placing the harness on a subject such that the treatment unit is positioned over a spleen of the subject.
The invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
In some aspects, provided are wearable harnesses positioning an ultrasound transducer to a subject's body. The wearable harnesses provided herein can include two adjustable shoulder straps, an adjustable waist strap, a pocket for holding a power pack, and a securing portion for holding the transducer. In some embodiments, the pocket for holding the transducer is positioned over the subject's spleen such that the ultrasound transducer may be positioned over the subject's spleen.
As explained above, conventional ultrasound systems are typically used for medical imaging. In recent years, some ultrasound systems are being used for immunomodulation. During immunomodulation, the ultrasonic waves emitted by these ultrasound systems stimulate nerves, such as the splenic nerve, into modulating the immune system in a non-invasive manner. Like conventional imaging ultrasound systems, the transducers of immunomodulatory ultrasound systems are typically positioned and operated by a medical professional during treatment.
Conversely, the harnesses provided herein allow a subject to consistently position and operate the transducer over a target, such as the splenic nerve, without requiring the presence of a medical professional. The transducers described herein are attached to a wearable harness that is fastened to a subject's body. The transducer is placed at a securing portion of the wearable harness that is configured to be positioned over the subject's spleen during proper fit and wear. When properly fit (e.g., adjusted) to the subject, the transducer can be positioned in the same location every time the harness is worn. Thus, the subject can wear, activate, and remove the harness without requiring a medical professional to readjust the harness before every ultrasound treatment. This enables the subject to receive at-home ultrasound treatment without the presence of a medical professional. In some embodiments, a harness can include commercially available and smart materials that can adapt to the body's shape, retain memory of the body, and ensure security of the ultrasound stimulator to provide continue ultrasound to a specific region of the target organ.
The wearable harnesses described herein can also be used to treat subjects shortly after an organ transplant. Unfortunately, only 20% of organ demand in the world is met. Even if a subject receives an organ transplant, one out of three subjects will reject their new organ. The current clinical standard is to put subjects on cocktails of immunosuppressant drugs, that have dangerous side-effects. No major advancements for the management of organ rejection have been seen for the past 40 years. Therefore, more personalized treatment is critical for the survival of these subjects.
Aspects and embodiments of the present invention can suppress the immune system via ultrasound stimulation of a target organ, such as the spleen, in a wearable device that the subject can use at home. Though the clinical effects are similar to the immune suppression observed with drugs, the typical dangerous side-effects are reduced as the system leverages the normal physiology of an individual which contains feedback mechanisms to prevent oversuppression. According to certain embodiments, by targeting the spleen and/or the splenic nerve, normal physiology can be controlled by inhibiting or enhancing its normal function. However, because the approach augments normal physiology, there is no risk for over-suppression as the body's normal feedback loop will be activated to prevent this side effect. According to certain aspects, the innovative design makes it possible for subjects to wear the device like a vest, without any knowledge of anatomy. As discussed in more detail below, according to certain examples, the device is configured to stimulate the spleen, the liver and nerves surrounding it with specific frequency or frequencies that have the desired effects. The wearable harness is fitted once at the clinic, and thereafter it can be modulated by the physician remotely with several parameters such as intensity, frequency, duration and more, depending on the subject response based on biomarker feedback that is taken periodically, e.g., once daily to once weekly, all personalized to the subject.
In some embodiments, the wearable harnesses described herein may, along with an ultrasound transducer, use low or high intensity focused ultrasound (LIFU/HIFU) to treat subjects with organ (e.g., kidney) transplants to prevent chronic or acute organ (e.g., kidney) rejection.
Embodiments of the wearable device are not limited to a wearable back brace, vest, or harness, but also include a patch design as well as a belt. Those skilled in the art, given the benefit of this disclosure, will appreciate that other wearable forms of the device may also be implemented. Regardless of the form or design of the wearable device, the device is configured such that it is fitted and rigid, so that it does not move during treatment.
Furthermore, embodiments of the wearable services and system disclosed herein allow clinics or hospitals to obtain monitored data from subjects. Any data collected during the wearable period may be collected. In some embodiments, the system may be used by subjects who suffer from acute or chronic organ (e.g., kidney) rejection; however, the system and methods of use disclosed herein can be applied to any other indication, not limited to kidney rejection. Embodiments may be used to treat any modulatory marker or any other biological function with the wearable device that can apply ultrasound stimulation to the body without any prior knowledge from the subject or person using it.
Embodiments of the device may be personalized to every single organ and subject. Embodiments of the device may replace all the immunosuppressant drugs, thus being able to deliver a personalized and home-based treatment approach that even has the potential to make studies into artificial kidney obsolete. Examples of advantages and value provided by embodiments of the device include the ability to provide opportunity to 1) reduce the cost of care (through fewer visits and early detection), 2) improve access to care (through home monitoring), and 3) improve outcomes (early detection and specific treatment means less organs wasted and therefore shorter organ transplant waiting list). Furthermore, the collection of data and the use of an artificial intelligence (AI) based cloud platform may allow for optimized and personalized care.
Unlike immunosuppressive drugs, where only the dosage can be adjusted, this technology has many parameters that can be personalized to the subject's need such as: location of stimulation, amplitude, pressure, and frequency of the stimulation, which can even be adjusted in real-time based on the monitored biomarkers. Furthermore, neuromodulation of the immune system via ultrasound stimulation of the splenic nerve may, over time, train the body to maintain a non-inflammatory state whereby the subject requires less immunosuppression via drugs or neuromodulation.
According to certain embodiments, the device can be compiled with companion monitoring devices as well as with artificial intelligence (through software algorithm, machine learning and/or other data processing methods) to predict and optimize the treatment regime. For example, embodiments of the wearable device described herein may include a communicator with a monitoring device (e.g., similar to a glucose monitor) to analyze the effect of the ultrasound stimulation, and either directly or through a cloud-based platform to provide optimization parameters to improve the stimulation.
A device according to certain embodiments is a closed-loop system that integrates biomarker monitoring with an ultrasound stimulator to evoke anti-inflammatory effects. Embodiments of the ultrasound stimulation device, packaged in the form of a wearable device, such as a belt, a patch or a back brace, for example. This technology is designed for the subject to bring home, which allows for the physician to treat subjects at home and adjust treatments remotely. Ultimately by treating subjects via bioelectronics, fewer organs will be fully rejected because they will be managed by the technology according to aspects and embodiments disclosed herein, and thereby resulting in a shorter organ waiting list. Bioelectronic medicine devices leverage the physiological mechanism, and thereby this treatment can never lead to a full suppression of the immune system unlike drugs, this therefore means that these subjects can taper off some of the immunosuppressant drugs with the most dangerous side effects, improving their quality of life significantly.
Data has shown that short periods of ultrasound stimulation of the spleen, vagus nerve, or the liver can reduce inflammatory cytokine markers in animal models and in humans. For example, one study shows that ultrasound stimulation of the spleen can be used to treat inflammatory arthritis in mouse models. Another study shows that ultrasound stimulation of the spleen reduces cytokine levels to the same levels as the more medically established procedure, implant-based vagus nerve stimulation. A third study shows that focused ultrasound on the porta hepatis can reduce cytokine markers in obese animals and reduce weight. A final study shows that ultrasound stimulation of the spleen lowers cytokines levels in humans.
Graft Rejection Mechanism: During allograft rejection, host immune cells, mostly T-cells and particularly CD4+ T-cells, recognize polymorphisms within the MHC and the minor histocompatibility complex. The T-cells can either be activated through direct allorecognition by recognizing intact donor MHC molecules on donor-derived APCs or they can be activated via indirect allorecognition by responding to processed donor-derived peptides bound to MHC molecules. Donor endothelial cells can also directly activate CD8+ T-cells, which can be a process constantly present after transplantation26. Embodiments of the wearable device according to aspects of the invention have been developed for the novice subject without any prior knowledge of the organs of interest. Therefore, only by placing the back brace, the patch or the belt, the device is fitted in such a way that it can modulate the above processes through targeting nerves connected to the spleen and the liver. Therefore, embodiments of the device may be crucial for the health of these subjects.
Referring to
Aspects and embodiments provide an individualized and adaptive system that integrates biomarker monitoring with ultrasound stimulation.
According to certain embodiments, the wearable device 100 has a built-in focused ultrasound device, that is adjusted and placed on the body to target the nerves on and around the spleen to dampen the immune system via the above mechanism of action also illustrated in
The system may further include a communications/monitoring module 300 that may be separate from the wearable device 100 or may be integrated with the wearable device 100. The communications module 300 allows remote communication, either directly or via a cloud platform or other intermediary, with the subject's (e.g., patient's) physician, and may allow for remote adjustment of one or more parameters of the device, as discussed above.

In some embodiments, the elastic panel 404 may be removable and washable. In some embodiments, such as if the two adjustable shoulder straps 402 merge into a single strap before they attach to the front panel 406, the elastic panel 404 may not connect to the front panel 406 or may be absent entirely. In some embodiments, the elastic panel 404 allows the harness to be more easily adjustable to different sized subject. For example, the elastic panel 404 ensures that the harness will fit narrow- and wide-shouldered subjects, such that, regardless of body shape, the harness is tightly fitted and snug to the subject's body.
As shown, front panel 406 includes a panel that covers at least a portion of the front of the subject's torso.

In some embodiments, the front panel 406 may cover most of the subject's torso. Alternatively, in some embodiments, the front panel 406 may be shaped like a belt that provides minimal coverage of the subject's torso. Front panel 406 may include a power pocket 407.
As shown, power pocket 407 includes a pocket that can hold a power pack on the harness 400. The power pocket 407 may be sewn or otherwise attached onto the front panel 406. Alternatively, in some embodiments, power pocket 407 may not be attached to front panel 406 but may instead be attached to a different location on the harness, such as an adjustable shoulder strap 402, an adjustable waist strap 413, or a rear panel 516 (see
As shown, power pocket outlet 414 includes an opening through which a power cable can extend into power pocket 407. The size of this opening may vary, so long as it is large enough for the power cable to extend through but no larger than the size of the power pack. The power pocket outlet 414 may be located near the bottom, side, center, or another area of power pocket 407.
As shown, transducer securing portion 408 includes a pocket that can hold a transducer case assembly on the harness 400. In some embodiments, the transducer securing portion 408 secures the transducer case assembly in one position to prevent the transducer from moving or falling off the harness 400. In such embodiments, the transducer case assembly can be repositioned and resecured if necessary. The transducer securing portion 408 may be sewn or otherwise attached onto the adjustable waist strap 413. Alternatively, in some embodiments, transducer securing portion 408 may not be attached to adjustable waist strap 413 but may instead be attached to a different location on the harness, such as an adjustable shoulder strap 402, a front panel 406, or a rear panel 516 (see
As shown, transducer securing portion outlet 409 includes an opening through which a power cable can extend into transducer securing portion 408. The size of this opening may vary, so long as it is large enough for the power cable to extend through but no larger than the size of the transducer case assembly. The transducer securing portion outlet 409 may be located near the bottom, side, center, or another area of transducer securing portion 408.
As shown, adjustable waist strap 413 includes a horizontal strap that may be supported by or positioned over the waist. The adjustable waist strap 413 may be connected to the front panel 406 by waist strap buckle 412. Alternatively, the method of connection may be, for example, and without limitations, directly molding or sewing the adjustable waist strap 413 and the front panel 406 together, fastening by VELCRO®, etc. The adjustable waist strap 413 may include padding or other cushioning features to enhance the subject's comfort. In some embodiments, the adjustable waist strap 413 may be inelastic to ensure a consistent fit of the harness 400 along the subject's waist. In such embodiments, the adjustable waist strap 413 may be made of one or more inelastic materials. The material may be, for example, and without limitations, canvas, plastic, etc. so long as the material is inelastic. In some embodiments, the adjustable waist strap 413 may be removable and washable. In some embodiments, one or more adjustable horizontal straps may run parallel to the adjustable waist strap 413 to further adjust how the harness 400 fits on the subject's body. In these embodiments, the one or more adjustable horizontal straps may be connected to the adjustable waist strap 413 or may merge into a single strap before it attaches to the front panel 406 via the waist strap buckle 412. The adjustable waist strap 413 may be adjusted in length to fit subjects of different heights, sizes, and body shapes and can be replaced if necessary. For example, if the subject is too small or large for the harness 400 and adjustable waist strap 413 no longer fits the subject, it may be replaced by an adjustable waist strap 413 of a different length. In some embodiments, in order to cover a greater region of the patient's torso, such as the region including the spleen, one side of the adjustable waist strap 413 may be wider than the other side. Adjustable waist strap 413 may include a waist strap scale 410, a waist strap clip 411, and/or a waist strap buckle 412.
As shown, waist strap scale 410 includes a scale that extends lengthwise along the adjustable waist strap 413.

Methods according to certain embodiments comprise the use of ultrasound waves in the low-intensity or low frequency range applied non-invasively to nerves, specifically the splenic nerve, and nerves surrounding the spleen to modulate, either inhibit or activate, the immune response. The ultrasound stimulation device may include one or several components that are commercially available or custom-made and generate the ultrasound waves, such as ultrasound emitters, transducers, piezo-electric transducers, composite transducers, capacitive micromachined ultrasound transducer or any other ultrasound emitting transducers, that could be single or multiple transducers and the waves could be in any shape both being focused and unfocused depending on the desired outcome that is needed. In certain examples, the ultrasound pressure ranges from 10 kPa to 800 kPa. The focused ultrasound may be emitted from a shallow ultrasound-focusing cone. In one embodiment, the ultrasound frequency exhibited to the body is <2.5 MHz. In certain examples, the ultrasound frequency may be in the range from 500 kHz to 2.5 MHz, with a pulse repetition ranging from 0.1 to 10 milliseconds (ms). The pulse length may range from 100 to 300 microseconds.
According to certain implementations, subjects may undergo treatment for from 1 minute to 30 minutes per day, for example, from 5 to 30 minutes per day, or from 10 to 15 minutes per day. The number of days of treatment may be determined by the subject's doctor, and may be up to the full lifetime of the subject. The number of days of treatment, and frequency of the treatment, may depend on health condition and disease state of the subject, and can range from daily to weekly to monthly.
Kidney transplant subjects can use the wearable device or harness according to various embodiments to deliver ultrasound stimulation to their spleens and reduce their cytokine levels, in addition to or instead of the cocktail of immunosuppressants which are currently the standard of care for subjects who have undergone a kidney transplantation. For kidney treatment, the ultrasound may be focused on the splenic region of the abdomen, as discussed above. However, in other applications, the ultrasound may be focused at different bodily regions, as appropriate.
Thus, aspects and embodiments provide a wearable harness for an ultrasound-emitting device that can be used to provide targeted ultrasound stimulation to one or more organs in a subject's body. For example, the wearable harness can be used with an ultrasound transducer that is applied non-invasively to the spleen. As discussed above, the wearable device/harness can be implemented in a form that is comfortable for the subject to wear and configured to be easy for the subject to correctly position the ultrasound emitter without requiring detailed knowledge of the organ location within the subject's body. The wearable device or harness can be used by the subject at home, without requiring the presence of a physician or another trained medical professional. Ultrasound stimulation/modulation provided by the ultrasound device of the harness may advantageously treat or improve a variety of medical conditions, as discussed above, including (but not limited to) reducing kidney transplant rejection through ultrasound applied to the spleen. Furthermore, as discussed above, embodiments of the device can be used to stimulate the splenic nerve and other nerves surrounding it to modulate other bodily functions beyond dampening the immune system in organ transplants. For example, Alzhiemer's disease (e.g., remyleination induction of the nerves), traumatic brain injury, chronic traumatic encephalopathy, autoimmune diseases such as lupus, dermatitis, eczema, psoriasis, psoriatic arthritis, endometriosis, scleroderma, Sjogren's, fibromyalgia, neuropathy, Wegener's granulomatosis, vascultities, temporal arteritis, celiac's disease, Crohn's disease, eczema, ulcerative colitis, inflammatory bowel disease, rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, non-alcoholic fatty liver disease, alcoholic fatty liver disease, dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, myocardial infarction, coronary artery disease, cardiovascular disease, reperfusion injury, diabetes types I and II, multiple sclerosis, depression, schizophrenia, bipolar disorder, autism spectrum disorder, major depression disorder, post-traumatic stress disorder, skin cancer, cellulitis, vitiligo, rosacea, cervicitis, herpes, HIV, menopause, aging, hair loss, hair greying, pelvic inflammatory disease, endometriosis, infertility, antiphospholipid syndrome, post and pre-transfusions, Rh incompatibility during pregnancy, post-plastic surgery, post-surgical interventions, sleep disorders, circadian rhythm disorders, insomnia, jet lag, hepatitis, and obesity.
