Subsequently, the device may receive instructions to apply the current to the anatomical element via a plurality of electrodes of the electrode device, where the current is configured to regulate insulin production of the patient. For example, a first electrode may be configured for placement on or around a celiac vagal trunk, where the current downregulates neural activity of the celiac vagal trunk, and a second electrode may be configured for placement on or around a hepatic vagal trunk, where the current upregulates neural activity of the hepatic vagal trunk.

Description

BACKGROUND

The present disclosure is generally directed to therapeutic neuromodulation and relates more particularly to a stimulation/block therapy to affect insulin production of a patient.

Diabetes represents a large and growing global health issue with estimates of over 537 million patients worldwide having been diagnosed with type 2 diabetes and estimates of 6.7 million annual deaths related to complications of diabetes. Despite different types of treatments being developed and utilized (e.g., medication, surgery, diet, etc.), type 2 diabetes remains challenging to effectively treat. Type 2 patients must frequently contend with keeping their blood sugar levels in a desirable glycemic range. Prolonged deviations can lead to long term complications such as retinopathy, nephropathy (e.g., kidney damage), cardiovascular disease, etc. Because treatment for diabetes is self-managed by the patient on a day-to-day basis (e.g., the patients self-inject the insulin), compliance or adherence with treatments can be problematic.

Additionally or alternatively, congenital hyperinsulinism, and more generally hyperinsulinism, is a condition where neonates or patients experience severe hypoglycemia (e.g., reduced blood sugar) due to abnormally high levels of insulin production that sometimes starts within the first few hours of birth. In some cases, the high levels of insulin production are due to a genetic mutation in potassium channels of the neonate/patient. Left untreated, congenital hyperinsulinism can be fatal.

Vagus nerve stimulation (VNS) is a technology that has been developed to treat different disorders or ailments of a patient, such as epilepsy and depression. In some examples, VNS involves placing a device in or on a patient's body that uses electrical impulses to stimulate the vagus nerve. For example, the device may be usually placed under the skin of the patient, where a wire (e.g., lead) and/or electrode connects the device to the vagus nerve. Once the device is activated, the device sends signals through the vagus nerve to the patient's brainstem (e.g., or different target area in the patient, such as other organs of the patient), transmitting information to their brain. For example, with VNS, the device may be configured to send regular, mild pulses of electrical energy to the brain via the vagus nerve. In some examples, the device may be referred to as an implantable pulse generator. An implantable vagus nerve stimulator has been approved to treat epilepsy and depression in qualifying patients.

The vagus nerve (e.g., also called the pneumogastric nerve, vagal nerve, the cranial nerve X, etc.) is responsible for various internal organ functions of a patient, including digestion, heart rate, breathing, cardiovascular activity, and reflex actions (e.g., coughing, sneezing, swallowing, and vomiting). Most patients may have one vagus nerve on each side of their body, with numerous branches running from their brainstem through their neck, chest, and abdomen down to part of their colon. The vagus nerve plays a role in many bodily functions and may form a link between different areas of the patient, such as the brain and the gut. The vagus nerve is a critical nerve for supplying parasympathetic information to the visceral organs of the respiratory, digestive, and urinary systems. Additionally, the vagus nerve is important in the control of heart rate, bronchoconstriction, and digestive processes. In some cases, the vagus nerve may be considered a mixed nerve based on including both afferent (sensory) fibers and efferent (motor) fibers. As such, based on including the two types of fibers, the vagus nerve may be responsible for carrying motor signals to organs for innervating the organs (e.g., via the efferent fibers), as well as carrying sensory information from the organs back to the brain (e.g., via the afferent fibers).

The vagus nerve has a number of different functions. Four key functions of the vagus nerve are carrying sensory signals, carrying special sensory signals, providing motor functions, and assisting in parasympathetic functions. For example, the sensory signals carried by the vagus nerve may include signaling between the brain and the throat, heart, lungs, and abdomen. The special sensory signals carried by the vagus nerve may provide signaling of special senses in the patient, such as the taste sensation behind the tongue. Additionally, the vagus nerve may enable certain motor functions of the patient, such as providing movement functions for muscles in the neck responsible for swallowing and speech. The parasympathetic functions provided by the vagus nerve may include digestive tract, respiration, and heart rate functioning. In some cases, the nervous system can be divided into two areas: sympathetic and parasympathetic. The sympathetic side increases alertness, energy, blood pressure, heart rate, and breathing rate. The parasympathetic side, which the vagus nerve is heavily involved in, decreases alertness, blood pressure, and heart rate, and helps with calmness, relaxation, and digestion.

VNS is considered a type of neuromodulation (e.g., a technology that acts directly upon nerves of a patient, such as the alteration, or “modulation,” of nerve activity by delivering electrical impulses or pharmaceutical agents directly to a target area). For example, as described above, VNS may include using a device (e.g., implanted in a patient or attached to the patient) that is configured to send regular, mild pulses of electrical energy to a target area of the patient (e.g., brainstem, organ, etc.) via the vagus nerve. The electrical pulses or impulses may affect how that target area of the patient functions to potentially treat different disorders or ailments of a patient.

In some examples, for epileptic patients that suffer from seizures, VNS may change how brain cells work by applying electrical stimulation to certain areas involved in seizures. For example, research has shown that VNS may help control seizures by increasing blood flow in key areas, raising levels of some brain substances (e.g., neurotransmitters) important to control seizures, changing electroencephalogram (EEG) patterns during a seizure, etc. As an example, an epileptic patient's heart rate may increase during a seizure or epileptic episode, so the VNS device may be programmed to send stimulation to the vagus nerve regular intervals and when periods of increased heart rate are seen, where applying stimulation at those times of increased heart rate may help stop seizures. Additionally or alternatively, depression has been tied to an imbalance in certain brain chemicals (e.g., neurotransmitters), so VNS is believed to assist in treating patients diagnosed with depression by using electricity (e.g., electrical pulses/impulses) to influence the production of those brain chemicals.

Diabetes represents a large and growing global health issue with estimates of over 537 million patients worldwide having been diagnosed with type 2 diabetes and estimates of 6.7 million annual deaths related to complications of diabetes. Despite different types of treatments being developed and utilized (e.g., medication, surgery, diet, etc.), type 2 diabetes remains challenging to effectively treat. Type 2 patients must frequently contend with keeping their blood sugar levels in a desirable glycemic range. Prolonged deviations can lead to long term complications such as retinopathy, nephropathy (e.g., kidney damage), cardiovascular disease, etc. Because treatment for diabetes is self-managed by the patient on a day-to-day basis (e.g., the patients self-inject the insulin), compliance or adherence with treatments can be problematic. Additionally, in a financial sense, global expenditures for type 2 diabetes treatments, preventive measures, and resulting consequences are estimated at about $966 billion per year. Compounding this issue of high global expenditures is the increasing price of insulin.

As described herein, a neuromodulation technique is provided for glycemic control (e.g., as a treatment for diabetes) using a stimulation/block therapy (e.g., type of VNS). For example, the neuromodulation technique may generally include using a device (e.g., including at least an implantable pulse generator) to provide electrical stimulation (e.g., electrical pulses/impulses) on one or more trunks of the vagus nerve (e.g., vagal trunks) to mute a glycemic response for patients with diabetes. The “patient” as used herein may refer to Homo sapiens or any other living being that has a vagus nerve.

In some examples, the device may provide stimulation/blocking of the celiac and hepatic vagal trunks (e.g., using the device) for the purposes of glycemic control. For example, the anterior sub diaphragmatic vagal trunk at the hepatic branching point of the vagus nerve may be electrically blocked (e.g., down-regulated) by delivering a high frequency stimulation (e.g., of about 5 kilohertz (kHz) or in a range between 1 kHz to 50 kHz). Additionally or alternatively, the posterior sub diaphragmatic vagal trunk at the celiac branching point of the vagus nerve may be electrically stimulated (e.g., up-regulated) by delivering a low frequency stimulation (e.g., a square wave at 1 Hz or within a range from 0.1 to 20 Hz). In some examples, the electrical blocking and/or electrical stimulating of the respective vagal trunks may be performed by using one or more cuff electrodes (e.g., of the device) placed on the corresponding vagal trunks (e.g., sutured or otherwise held in place). The desired response by providing the stimulation/block therapy is a muting of the glycemic response of a patient. In some examples, muting of the glycemic response may refer to a lower post prandial peak of the glycemic response as compared to a peak without the stimulation/block therapy being applied.

Using the stimulation/block therapy to achieve a muting of the glycemic response is advantageous for those with type 2 diabetes where the postprandial glycemic response (e.g., occurring after a meal) can be very high. For example, some patients with type 2 diabetes may have high blood sugar levels (e.g., glucose levels) after eating a meal based on their reduced or lack of insulin production (e.g., normal insulin production in the body lowers blood sugar levels postprandially by promoting absorption of glucose from the blood into different cells). Additionally or alternatively, patients diagnosed with type 2 diabetes may generally have high glycemic levels at different points of the day (e.g., not necessarily postprandially or immediately after a meal). Over time, the effect of high glycemic values can have a detrimental effect on one's health, leading to neuropathy, retinopathy, and other ailments. Accordingly, by using the stimulation/block therapy provided herein, a high glycemic response experienced by type 2 diabetes patients may be muted (e.g., the glycemic response is reduced, particularly post prandially). Additionally, the therapy aims to improve insulin sensitivity by blocking hepatic glucose production and also by stimulating pancreatic insulin production needed for glycemic control, where the lack of insulin sensitivity can potentially lead to an imbalance in glycemic control and consequent systemic complications in patients with type 2 diabetes. In some examples, the therapy may also improve fasting hyperglycemia, which can be commonly seen in patients with type 2 diabetes.

Additionally or alternatively, as described herein, a device (e.g., implantable pulse generator) configured to provide a stimulation to the celiac and hepatic vagal trunks (e.g., or another anatomical element of the patient) may be used in the context of treating hyperinsulinism (e.g., congenital hyperinsulinism). Congenital hyperinsulinism, and more generally hyperinsulinism, is a condition where neonates or patients experience severe hypoglycemia (e.g., reduced blood sugar) due to abnormally high levels of insulin production that sometimes starts within the first few hours of birth. In some cases, the high levels of insulin production are due to a genetic mutation in potassium channels of the neonate/patient (e.g., adenosine triphosphate (ATP)-sensitive potassium (kATP or K_ATP) channels). Left untreated, congenital hyperinsulinism can be fatal. In many cases, children diagnosed with hyperinsulinism or congenital hyperinsulinism do not survive very long.

In some cases, the only treatment currently available for treating hyperinsulinism and congenital hyperinsulinism is a pancreatectomy (e.g., removal of a patient's pancreas). However, pancreatectomies come with different problems. Due to having their pancreas removed, the patients may be unable to digest food on their own and may rely on other feeding methods to properly digest their meals. Further, with no pancreas, the patient's body may be unable to regulate its own blood glucose, such that the patients require around-the-clock glucose management through insulin and glucagon injections or pump therapy, affecting the patient's lifestyle drastically from an early age (e.g., sometimes all before the patient is two (2) years of age).

Hyperinsulinism is the most frequent cause of severe, persistent hypoglycemia in newborn babies, infants, and children. In most countries, hyperinsulinism occurs in approximately 1/25,000 to 1/50,000 births. About 60% of babies with hyperinsulinism are diagnosed during the first month of life. An additional 30% of babies with hyperinsulinism are diagnosed after the first month but within their first year of life, and the remainder of patients with hyperinsulinism are diagnosed after that first year of life.

Using techniques described herein, neuromodulation techniques are provided that can be used to treat hyperinsulinism and/or other metabolic syndromes. For example, the neuromodulation techniques may include delivering a current or signal to one or more branches of the vagus nerve that results in a blocking of the celiac branch of a patient's vagus nerve (e.g., celiac vagal trunk) that regulates insulin production from the patient's pancreas. Blocking the celiac branch of the vagus nerve may offer patients a better chance of managing hyperinsulinism.

As part of blocking the celiac branch of the vagus nerve, electrodes (e.g., one or more cuff electrodes) may be placed on the celiac branch of the vagus nerve and/or other branches of the vagus nerve, and the electrodes may be configured to deliver a current or signal (e.g., generated by an implantable pulse generator) to the branch(es) of the vagus nerve, such that the current or signal blocks neural activity on the celiac branch of the vagus nerve that regulates insulin production in the patient. For example, the current may be used to deliver a high frequency stimulation to the celiac branch of the vagus nerve that blocks neural activity of the celiac branch, which then blocks signaling to the pancreas that would otherwise cause the pancreas to produce excessive amounts of insulin in the patient. Accordingly, medical professionals (e.g., pediatricians) and the patients may be able to block excess insulin production and regulate insulin production at will for the patient using the stimulation therapy and neuromodulation techniques described herein.

Further, because the stimulation therapy obviates the need for a pancreatectomy, patients do not have to rely on alternative feeding methods (e.g., such as consuming partially digested food). Thus, the nerve modulation therapy may offer patients both a chance at a longer and healthier life and a better lifestyle. In some examples, the patients may use continuous glucose monitoring (e.g., via a glucose sensor) while on the nerve modulation therapy to achieve better glycemic control.

Embodiments of the present disclosure provide technical solutions to one or more of the problems of (1) treating congenital hyperinsulinism and, more generally, hyperinsulinism and (2) lifestyle impacts that result from pancreatectomies. For example, the nerve modulation therapy provided herein can be used to treat hyperinsulinism and congenital hyperinsulinism by providing electrical stimulation to one or more vagal trunks of a patient to regulate or decrease insulin production in the patient. Additionally, the nerve modulation therapy obviates the need for a pancreatectomy, thereby increasing a standard of living for the patient that would have otherwise been impacted by the removal of a patient's pancreas, such as requiring the patient to consume partially digested food or around-the-clock glucose management through insulin and glucagon injections or pump therapy.

Turning to FIG. 1, a diagram of a system 100 according to at least one embodiment of the present disclosure is shown. The system 100 may be used to provide insulin production regulation for a patient and/or carry out one or more other aspects of one or more of the methods disclosed herein. For example, the system 100 may include at least a device 104 that is capable of providing a stimulation/blocking therapy that blocks excessive insulin production for patients with hyperinsulinism. In some examples, the device 104 may be referred to as an implantable pulse generator. Additionally, the system 100 may include one or more wires 108 (e.g., leads) that provide a connection between the device 104 and nerves of the patient for enabling the stimulation/blocking therapy.

As described previously, neuromodulation techniques (e.g., technologies that act directly upon nerves of a patient, such as the alteration, or “modulation,” of nerve activity by delivering electrical impulses or localized pharmaceutical agents directly to a target area) may be used for assisting in treatments for different diseases, disorders, or ailments of a patient, such as epilepsy and depression. Accordingly, as described herein, the neuromodulation techniques may be used for blocking excess insulin production in the patient to assist in the treatment of hyperinsulinism for the patient. For example, the device 104 may provide electrical stimulation to one or more trunks of the vagus nerve of the patient (e.g., via the one or more wires 108) to provide the stimulation/blocking therapy for supporting insulin regulation in the patient.

In some examples, the one or more wires 108 may include at least a first wire 108A and a second wire 108B connected to respective vagal trunks (e.g., different trunks of the vagus nerve). As described previously, most patients have one vagus nerve on each side of their body, with numerous branches or trunks running from their brainstem through their neck, chest, and abdomen down to part of their colon. The vagus nerve plays a role in many bodily functions and may form a link between different areas of the patient, such as the brain and the gut. For example, the vagus nerve is responsible for various internal organ functions of a patient, including digestion, heart rate, breathing, cardiovascular activity, and reflex actions (e.g., coughing, sneezing, swallowing, and vomiting).

Accordingly, the first wire 108A may be connected to a first vagal trunk of the patient (e.g., the posterior sub diaphragmatic vagal trunk at the celiac branching point of the vagus nerve, celiac vagal trunk, celiac branch of the vagus nerve, etc.) to provide an electrical blocking signal (e.g., a down-regulating signal) from the device 104 to the first vagal trunk (e.g., by delivering a high frequency stimulation, such as a given waveform at about 5 kHz or within a range from 1 kHz to 50 kHz). Additionally or alternatively, the second wire 108B may be connected to a second vagal trunk of the patient (e.g., the anterior sub diaphragmatic vagal trunk at the hepatic branching point of the vagus nerve, hepatic vagal trunk, hepatic branch of the vagus nerve, etc.) to provide an electrical stimulation signal (e.g., an up-regulating signal) from the device 104 to the second vagal trunk (e.g., by delivering a low frequency stimulation, such as a square wave or other waveform at 1 Hz or within a range from 0.1 to 20 Hz). By providing the electrical blocking signal and the electrical stimulation signal to the respective vagal trunks, the system 100 may provide a blocking of excessive insulin production in the patient when the stimulation/blocking therapy is applied.

In some examples, the vagal trunks to which the wires 108 are connected may be connected to or otherwise in the vicinity of one or more organs of the patient, such that the blocking/stimulation signals provided to the respective vagal trunks by the wires 108 and the device 104 are delivered to the one or more organs. For example, the first vagal trunk (e.g., to which the first wire 108A is connected) may be connected to a first organ 112 of the patient, and the second vagal trunk (e.g., to which the second wire 108B is connected) may be connected to a second organ 116. Additionally or alternatively, while the respective vagal trunks are shown as being connected to the corresponding organs of the patient as described, the vagal trunks to which the wires 108 are connected may be connected to the other organ (e.g., the first vagal trunk is connected to the second organ 116 and the second vagal trunk is connected to the first organ 112) or may be connected to different organs of the patient. In some examples, the first organ 112 may represent a liver of the patient, and the second organ 116 may represent a pancreas of the patient. In such examples, the blocking/stimulation signals provided by the wires 108 and the device 104 may be delivered to the liver and/or pancreas of the patient to block excessive insulin production in the patient as described herein.

In some examples, the wires 108 may provide the electrical signals to the respective vagal trunks via electrodes of an electrode device (e.g., cuff electrodes) that are connected to the vagal trunks (e.g., sutured in place, wrapped around the nerves of the vagal trunks, etc.). In some examples, the wires 108 may be referenced as cuff electrodes or may otherwise include the cuff electrodes (e.g., at an end of the wires 108 not connected or plugged into the device 104). Additionally or alternatively, while shown as physical wires that provide the connection between the device 104 and the one or more vagal trunks, the cuff electrodes may provide the electrical blocking and/or stimulation signals to the one or more vagal trunks wirelessly (e.g., with or without the device 104).

Additionally, while not shown, the system 100 may include one or more processors (e.g., one or more DSPs, general purpose microprocessors, graphics processing units, ASICs, FPGAs, or other equivalent integrated or discrete logic circuitry) that are programmed to carry out one or more aspects of the present disclosure. In some examples, the one or more processors may include a memory or may be otherwise configured to perform the aspects of the present disclosure. For example, the one or more processors may provide instructions to the device 104, the cuff electrodes, or other components of the system 100 not explicitly shown or described with reference to FIG. 1 for providing the stimulation/blocking therapy to regulate insulin production in a patient as described herein. In some examples, the one or more processors may be part of the device 104 or part of a control unit for the system 100 (e.g., where the control unit is in communication with the device 104 and/or other components of the system 100).

In some examples, the system 100 may also optionally include a glucose sensor 120 that communicates (e.g., wirelessly) with other components of the system 100 (e.g., the device 104, the one or more processors, etc.) to achieve better glycemic control in addition to regulating insulin production. For example, the glucose sensor 120 may continuously monitor glucose levels of the patient, such that if the glucose sensor 120 determines glucose levels are low in the patient (e.g., or outside a normal or desired range for the patient, such that glucose levels are determined to be too high or too low in the patient), the glucose sensor 120 may communicate that glucose levels are getting low to the device 104 (e.g., via the one or more processors) to signal for the device 104 to apply the stimulation/blocking therapy described herein to block insulin production in the patient as a possible technique to raise glucose levels in the patient.

The system 100 or similar systems may be used, for example, to carry out one or more aspects of any of the methods 300 and/or 400 described herein. The system 100 or similar systems may also be used for other purposes. It will be appreciated that the human body has many vagal nerves and the stimulation and/or blocking therapies described herein may be applied to one or more vagal nerves, which may reside at any location of a patient (e.g., lumbar, thoracic, etc.). Further, a sequence of stimulations and/or blocking therapies may be applied to different nerves. For example, a low frequency stimulation may be applied to a first nerve and a high frequency blockade may be applied to a second nerve.

FIG. 2 depicts a system 200 according to at least one embodiment of the present disclosure is shown. In some examples, the system 200 may implement aspects of or may be implemented by aspects of the system 100 as described with reference to FIG. 1. For example, the system 200 may be used to provide insulin production regulation for a patient and/or carry out one or more other aspects of one or more of the methods disclosed herein. Additionally, the system 200 may include at least a device 204 that is capable of providing a stimulation/blocking therapy that blocks excessive insulin production for patients with hyperinsulinism. In some examples, the device 204 may be referred to as an implantable pulse generator or implantable neurostimulator. Additionally, the system 200 may include one or more wires 208 (e.g., leads) that provide a connection between the device 204 and nerves of the patient for enabling the stimulation/blocking therapy. The device 204 and the one or more wires 208 may represent examples of the corresponding device 104 and the one or more wires 108, respectively, as described with reference to FIG. 1.

The system 200 may block excess insulin production in the patient by delivering a current generated by the device 204 to an anatomical element via the one or more wires 208. For example, the current may be applied to one or more vagal trunks 216 of the patient using one or more electrode devices 212 that receive the current from the device 204 (e.g., via the wires 208 or wirelessly). In some examples, the electrode devices 212 may each include a body and a plurality of electrodes that are disposed on the respective bodies, where the plurality of electrodes are configured to apply the current generated by the device 204 to the one or more vagal trunks 216. As shown, a first electrode device 212A (e.g., a first electrode or first cuff electrode) may be configured for placement on a first vagal trunk 216A to apply a current to the first vagal trunk 216A (e.g., carried via a first wire 208A or wirelessly instructed to apply the current), and a second electrode device 212B (e.g., a second electrode or second cuff electrode) may be configured for placement on a second vagal trunk 216B to apply a current to the second vagal trunk (e.g., carried via a second wire 208B or wirelessly instructed to apply the current). In some examples, the electrode devices 212 may be referred to as cuff electrodes.

In some examples, the first vagal trunk 216A may represent a celiac vagal trunk of the patient, and the second vagal trunk 216B may represent a hepatic vagal trunk of the patient. Accordingly, applying the current to the first vagal trunk 216A via the first electrode device 212A may downregulate (e.g., block) neural activity of the celiac vagal trunk, and applying the current to the second vagal trunk 216B via the second electrode device 212B may upregulate (e.g., stimulate) neural activity of the hepatic vagal trunk. By downregulating the neural activity of the celiac vagal trunk, excess insulin production in the patient may be blocked or reduced based on signaling between the celiac vagal trunk and a patient's pancreas being blocked, resulting in the pancreas decreasing insulin production and aiding in the treatment of hyperinsulinism.

In some examples, the current being applied to each vagal trunk 216 may be different per electrode device 212 or may include different parameters for application to each vagal trunk. For example, the first electrode device 212A may apply a high frequency stimulation (e.g., such as a given waveform at about 5 kHz) to provide an electrical blocking signal (e.g., a down-regulating signal) from the device 204 to the first vagal trunk 216A. Additionally or alternatively, the second electrode device 212B may apply a low frequency stimulation (e.g., such as a square wave or other waveform at 1 Hz) to provide an electrical stimulation signal (e.g., an up-regulating signal) from the device 204 to the second vagal trunk 216B. The combined effect of providing the same current with different parameters or respective currents with respective parameters to each of the vagal trunks 216 may result in providing a blocking of excessive insulin production in the patient when the stimulation/blocking therapy is applied. Subsequently, the patient may also experience an increase in blood sugar or glucose levels based on applying the stimulation/blocking therapy (e.g., to mitigate hypoglycemia).

Additionally, while not shown, the system 200 may also include a monitoring device (e.g., a glucose sensor) that is configured to continuously monitor glucose levels in the patient. In some examples, the electrode devices 212 may apply the current(s) to the vagal trunks 216 based on the monitoring device detecting decreased glucose levels in the patient. Accordingly, the monitoring device may communicate (e.g., wirelessly) with other components of the system 200 (e.g., the device 204, one or more processors, etc.) to achieve better glycemic control in addition to regulating insulin production. For example, the monitoring device may determine glucose levels are low in the patient and, as such, may communicate that glucose levels are getting low to the device 204 (e.g., via the one or more processors or directly) to signal for the device 204 to apply the stimulation/blocking therapy described herein to block insulin production in the patient as a possible technique to raise glucose levels in the patient and mitigate hyperinsulinism and/or hypoglycemia in the patient.

FIG. 3 depicts a method 300 that may be used, for example, to perform neuromodulation techniques (e.g., a stimulation/block therapy) to provide insulin production regulation for a patient to treat hyperinsulinism in the patient.

The method 300 (and/or one or more steps thereof) may be carried out or otherwise performed, for example, by at least one processor. The at least one processor may be the same as or similar to the processor(s) of the device 104 described above. The at least one processor may be part of the device 104 (such as an implantable pulse generator) or part of a control unit in communication with the device 104. A processor other than any processor described herein may also be used to execute the method 300. The at least one processor may perform the method 300 by executing elements stored in a memory (such as a memory in the device 104 as described above or a control unit). The elements stored in the memory and executed by the processor may cause the processor to execute one or more steps of a function as shown in method 300. One or more portions of a method 300 may be performed by the processor executing any of the contents of memory, such as providing a stimulation/block therapy and/or any associated operations as described herein.

The method 300 comprises transmitting instructions to a device (e.g., the device 104 or 204 as described with reference to FIGS. 1 and 2, such as an implantable pulse generator) to apply a current generated by the device to an anatomical element of the patient via a plurality of electrodes of an electrode device, where the current regulates insulin production of the patient (step 304). In some examples, the anatomical element may comprise a celiac vagal trunk and a hepatic vagal trunk of the patient. Accordingly, a first electrode of the plurality of electrodes may be configured for placement on the celiac vagal trunk, and a second electrode of the plurality of electrodes may be configured for placement on the hepatic vagal trunk.

The method 300 also comprises transmitting instructions to the device to apply the current to the celiac vagal trunk via the first electrode to downregulate neural activity of the celiac vagal trunk (step 308). The method 300 also comprises transmitting instructions to the device to apply the current to the hepatic vagal trunk via the second electrode to upregulate neural activity of the hepatic vagal trunk (step 312). By applying the current to the respective vagal trunks to downregulate/upregulate the corresponding neural activity of each vagal trunk, the patient may be able to regulate their insulin production at will. For example, insulin production of the patient may be reduced based on applying the current to the vagal trunks (e.g., insulin production of the patient is reduced at a pancreas of the patient). Additionally, applying the current to the vagal trunks may result in an increase in blood sugar or glucose levels in the patient.

The present disclosure encompasses embodiments of the method 300 that comprise more or fewer steps than those described above, and/or one or more steps that are different than the steps described above.

FIG. 4 depicts a method 400 that may be used, for example, to provide better glycemic control for a patient in addition to providing a stimulation therapy to regulate insulin production in the patient.

The method 400 (and/or one or more steps thereof) may be carried out or otherwise performed, for example, by at least one processor. The at least one processor may be the same as or similar to the processor(s) of the device 104 described above. The at least one processor may be part of the device 104 (such as an implantable pulse generator) or part of a control unit in communication with the device 104. A processor other than any processor described herein may also be used to execute the method 400. The at least one processor may perform the method 400 by executing elements stored in a memory (such as a memory in the device 104 as described above or a control unit). The elements stored in the memory and executed by the processor may cause the processor to execute one or more steps of a function as shown in method 400. One or more portions of a method 400 may be performed by the processor executing any of the contents of memory, such as providing a stimulation/block therapy and/or any associated operations as described herein.

The method 400 comprises determining if glucose levels in a patient have decreased (step 404). For example, the patient may have a monitoring device attached to themselves or implanted within themselves (e.g., the glucose sensor 112 as described with reference to FIG. 1) that is configured to continuously monitor glucose levels in the patient. Accordingly, this monitoring device may communicate with the at least one processor to indicate if glucose levels in the patient are low or fall below a threshold value. In some examples, low glucose levels may be representative of hyperinsulinism and/or hypoglycemia. As such, if the glucose levels become low, the neuromodulation techniques for applying the stimulation/block therapy as described herein may be used to decrease insulin production and/or increase glucose levels in the patient.

The method 400 also comprises transmitting instructions to a device (e.g., the device 104 or 204 as described with reference to FIGS. 1 and 2, such as an implantable pulse generator) to apply the current generated by the device to the anatomical element of the patient via the plurality of electrodes of the electrode device (step 408). In some examples, the processor may determine to transmit the instructions to the device to apply the generated current to the anatomical element based on determining the glucose levels in the patient have decreased.

The present disclosure encompasses embodiments of the method 400 that comprise more or fewer steps than those described above, and/or one or more steps that are different than the steps described above.

As noted above, the present disclosure encompasses methods with fewer than all of the steps identified in FIGS. 3 and 4 (and the corresponding description of the methods 300 and 400), as well as methods that include additional steps beyond those identified in FIGS. 3 and 4 (and the corresponding description of the methods 300 and 400). The present disclosure also encompasses methods that comprise one or more steps from one method described herein, and one or more steps from another method described herein. Any correlation described herein may be or comprise a registration or any other correlation.
