Embodiment Construction

[0049] A first exemplary embodiment of an electronically controlled capsule or drug delivery system according to the present disclosure is shown in FIG. 1 and described in detail below. The electronically controlled capsule 100 is an independent electronically controlled drug delivery system. As described in detail below, the electronically controlled capsule 100 includes programmed electronics that control the release mechanism to dispense the drug according to a dispense pattern. Capsule 100 is made using biocompatible materials such that capsule 100 is biocompatible at least for the amount of time it takes to pass through the gastrointestinal tract. The biocompatible material is preferably stable at room temperature, allowing the capsules to have a long shelf life. As used herein and in the claims, the word "drug" refers to internal medicines, non-medicinal substances, contrast media, gases, fluids, liquids, chemicals, radioactive reagents, imaging or medical markers, sig...

Abstract

An electronically controlled capsule or medicament delivery system (900) is provided. Disposed within a housing (102) of the system (900) configured for internal placement within a patient is a reservoir (960) for storing medicament. The reservoir (960) communicates with at least one respective aperture (970) of the housing (102). A pressure mechanism (962) is provided for displacing medicament stored within the reservoir (960) for causing the medicament to exit the housing (102) through the at least one respective aperture (970). At least one a closure member (966) is provided. Respective closure members (966) are in fluid communication with an associated aperture. The respective closure members (966) are actuatable between a closed state for substantially blocking flow of the medicament through the respective closure member (966) and an open state for permitting flow of the medicament through the respective closure member (966) for dispensing of the medicament. Control circuitry (906) is provided for controlling at least one of the pressure mechanism (962) and actuation of the respective closure members (966).

Description

technical field [0001] The present invention generally relates to electronically controlled capsules. More specifically, the present invention relates to systems and methods for dispensing medication from electronically controlled capsules. Background technique [0002] The drug is usually given in capsule or liquid form and taken at least once a day. A person may need to take or be given several medications at the same or different times each day. This requires him or his caregivers to maintain a diary or remember which medications are taken or administered at different times of the day. [0003] Drugs that people take, such as aspirin, usually pass through the digestive tract, where they are absorbed to treat a disease or condition. Typically, it takes 20 to 40 hours for the target to pass through the digestive tract. Several drugs are available as time-release capsules, which are used to release portions of the drug into the body at different times. Time-release caps...
