Abstract: This invention is a device and method for automatic and selective modification of the taste and/or smell of one or more selected nutrient or food types as food is being digested within a person's mouth. This invention can comprise: multiple taste and/or smell modifying substances; multiple reservoirs for these substances that are implanted within the person's body; and a flow control mechanism that automatically and selectively increases flowable communication between these substances and the person's oral cavity or nasal cavity when a selected nutrient or food is being digested within the person's mouth. This invention can help a person to moderate their consumption of unhealthy food and to limit their overall caloric intake as part of a comprehensive system for improved nutrition, energy balance, and weight management.

Abstract: This invention is an expandable intragastric device for reducing food consumption and/or absorption. In an example, this device can be embodied in a plurality of longitudinal expandable members which are arranged in a colonnade configuration to form a restrictive food lumen within a stomach. Pumping a flowable substance between the interiors of these expandable members changes the rate of food flow through the stomach, the capacity of the stomach to hold food, and/or the amount of food absorbed by the body. This offers some of the beneficial effects of gastric sleeve surgery, while also being adjustable and reversible.

Abstract: This invention is an implanted extracardiac device for supplementing blood circulation which comprises an implanted blood flow lumen, a blood flow increasing mechanism, and a control unit. Its design improves blood circulation when the blood flow increasing mechanism is operating, without hindering native blood flow when the mechanism is not operating. This device improves circulation without intruding on cardiac tissue or weakening the heart by completely supplanting cardiac function. Also, since the device allows native blood flow when the blood flow increasing mechanism is not in operation, it requires less power and can enable more patient mobility.

In an example, the wearable sensor can be part of a smart watch or smart bracelet. In an example, the imaging member can be part of a smart phone. The integrated operation of the wearable sensor and the imaging member disclosed in this invention offers accurate measurement of food consumption with low intrusion into the person's privacy.

These devices and methods can help people to better manage their food consumption, energy balance, and weight.
