Adaptive gastric vibrational therapy system with chewing detection and physiological monitoring

A method for adaptive control of gastric satiety therapy, the method comprising the steps of:

• delivering, by a gastric vibrational therapy device, non-invasive mechanical stimulation to a gastric region of a user;
• monitoring, by a chewing detection sensor, eating behavior of the user to generate chewing data indicative of a chewing cadence;
• acquiring, by a physiological monitoring device, physiological data from the user;
• receiving, by a controller in communication with the gastric vibrational therapy device, the chewing detection sensor, and the physiological monitoring device, the chewing data from the chewing detection sensor;
• receiving, by the controller, the physiological data from the physiological monitoring device;
• determining, by the controller, a target chewing cadence based on the physiological data;
• calculating, by the controller, a deviation between the chewing cadence and the target chewing cadence;
• and
• modulating, by the controller, operational parameters of the gastric vibrational therapy device based on the calculated deviation.

A multi-position gastric vibrational therapy system comprising:

• a first gastric vibrational therapy device configured to be positioned over a cardio region of a stomach of a user;
• a second gastric vibrational therapy device configured to be positioned over a pylorus region of the stomach of the user;
• and
• a controller in communication with the first gastric vibrational therapy device and the second gastric vibrational therapy device, the controller configured to independently control a first operating frequency of the first gastric vibrational therapy device and a second operating frequency of the second gastric vibrational therapy device based on differential tissue attenuation between the cardio region and the pylorus region to deliver a target stimulation frequency in the range of 60-100 Hz to nerve fibers at each region, wherein the first operating frequency and the second operating frequency are each in the range of 80-250 Hz.
