Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue.

A vibrating ingestible capsule includes a housing, and having a vibrating agitator adapted such that, in a first vibrating mode of operation, the housing exerts vibrations on an environment surrounding the capsule. A temperature sensor produces temperature information signals. A control element receives a series of temperature information signals from the temperature sensor, compares a measured temperature-over-time pattern, which is based on the series of temperature information signals, to a predetermined temperature-over-time pattern, and, after the measured temperature-over-time corresponds to the predetermined temperature-over-time pattern, activates the vibrating agitator to operate in the first vibrating mode of operation. The predetermined temperature-over-time pattern includes a temperature transition from a first temperature to a second temperature within human body temperature range, which may exceeds the first temperature by a temperature differential of at least 3° C. A rate of the temperature transition may be at least 4° C. per hour.

A method and system for gastric stimulation and imaging for a user. The system having an array of millimeter-sized gastric seeds implanted in a stomach area of a user. Each gastric seed is ultrasonically powered and communicates using a transducer, and the transducer has a recorder to measure a bioelectrical activity in the stomach area of the user. A wearable unit (WU) is worn or carried by the user, and the WU wirelessly powers the gastric seeds. The WU wirelessly communicates with the gastric seeds, and the gastric seeds communicate a parameter to the WU based on the bioelectrical activity. Received pulses by the seeds can he used to localize the position of the seeds and guide the wireless power/data transmission in a self-image-guided manner. A processing unit (PU) wirelessly communicates with the WU, and the WU communicates the parameters from the gastric seeds to the PU.

The present disclosure relates to various anchoring assemblies, systems, and methods for a catheter delivered device or otherwise implantable biomedical sensors. In one instance the anchoring systems of the present disclosure are designed to be used in connection with a biomedical sensor configured to be placed in the various locations within the anatomy of a patient including: a junction of a renal vein and an inferior vena cava, a junction of a jugular vein branch and a subclavian vein branch, a junction of a brachiocephalic vein branch and a superior vena cava, or a junction of an iliac vein branch and an inferior vena cava. In one embodiment, an biomedical sensor and anchoring system can be implanted in an organ of a patient or in an organ to be transplanted within a patient.

The device, that can be implanted in the intestinal cavity, comprises a reactor comprising a semi-permeable or porous membrane or coating linked to a element for attachment to an intestinal or gastric wall. The reactor can be in the form of a ribbon, a structure having more than two faces or an open structure delimiting a lumen, comprising, or formed from, a semi-permeable or porous membrane. The reactor can also delimit, at least partially with the semi-permeable or porous membrane of same, a closed inner space. The reactor can comprise or carry enzymes or micro-organisms, in particular bacteria or yeast. The reactor is used for generating a chemical reaction with one or more molecules present in the intestine, or for producing one or more biologically active molecules. It can, in particular, be used for consuming sugars, disaccharides and simple sugars or producing essential amino acids or other molecules having a positive effect on the health.

The capsule may also include a power source, a controller, and an impedance sensor. The impedance sensor may be configured to measure an impedance within the body lumen.

A system and method by which a catheter tube may be automatically driven to a target location within the body of a subject, such as an enteral cavity or respiratory tract of the subject. The catheter tube may include an imaging device, a transceiver, a spectrometer, and a battery embedded in a tube wall at a distal end of the catheter tube. The imaging device may capture image data of structures proximal to the distal end of the catheter tube. An articulated stylet may be inserted in the catheter tube, which may be controlled by a robotic control engine according to navigation data generated by an artificial intelligence (AI) model based on the topographical image data. The spectrometer may sample and identify biomarkers proximal to the catheter tube. A remote computer may implement the robotic control engine and AI model and may wirelessly receive the image data from the transceiver.
