First Claim
Patent Images
1. An ingestible capsule for administering a drug for treatment of a disease in a gastrointestinal tract of a mammal according to a pre-determined drug release profile, the gastrointestinal tract having sites of diseased tissue and normal tissue, the capsule comprising:
- a drug reservoir for storing the drug;
a drug dispensing device for dispensing or stopping the dispensing of the drug from the drug reservoir into the gastrointestinal tract;
an electronic control circuitry communicating with the drug dispensing device for regulating amount and time interval for dispensing of the drug into the gastrointestinal tract by the drug dispensing device according to a predetermined drug release profile, wherein the electronic control circuitry further comprises a memory for storage or updating of data specific to the predetermined drug release profile for the mammal;
at least one sensor configured to communicate with the electronic control circuitry; and
a non-digestible outer protective shell housing the drug reservoir, the drug dispensing device and the electronic control circuitry;
wherein the drug is substantially dispensed at the diseased tissue sites by the electronic control circuitry activating the drug dispensing device in response to detection of a biological condition by the at least one sensor,wherein the at least one sensor is a threshold sensor that detects a level of the biological condition crossing a predetermined threshold, andwherein the electronic control circuitry is configured to start a timer for the dispensing of the drug into the gastrointestinal tract in response to the level of the biological condition crossing the predetermined threshold.

Abstract
The present invention discloses an ingestible capsule containing drug and a method for controlled administration of the drug in a mammal for treatment of a disease of the GI tract. The capsule has electronic control means for dispensing the drug substantially to the diseased tissue sites of the GI tract, according to a pre-determined drug release profile obtained prior to administration from the specific mammal.

7. A method for administration of a drug for treatment of a disease in a gastrointestinal tract of a mammal according to a pre-determined drug release profile, the gastrointestinal tract having sites of diseased tissue and normal tissue, the method comprising the acts of:
-
orally administering to the mammal an ingestible capsule that includes the drug; detecting of a biological condition by at least one sensor included in the capsule, wherein the capsule further includes a drug dispensing device and a controller; and in response to the detecting act, activating the drug dispensing device by the controller for dispensing the drug in the gastrointestinal tract according to a predetermined drug release profile, wherein the drug is substantially dispensed at the diseased tissue sites, wherein the detecting act includes detecting a level of the biological condition crossing a predetermined threshold, and wherein the activating act includes starting a timer for the dispensing of the drug into the gastrointestinal tract in response to the level of the biological condition crossing the predetermined threshold. - View Dependent Claims (8, 9, 10, 11, 12, 17, 18, 19, 20, 22)
