Abstract: In accordance with some non-limiting examples of the disclosed subject matter, an ingestible system configured to acquire physiological information from an interior of a subject is provided, comprising a substrate and at least one physiological sensor. The at least one physiological sensor can be coupled to the substrate and configured to capture physiological data from at least one of an internal area or an orientation in a digestive tract of the subject. The system can include a controller coupled to the substrate and configured to receive the physiological data and prepare the physiological data for one of transmission from the subject or analysis of the physiological data. The substrate, including the at least one physiological sensor and the controller coupled thereto can be configured to self-orient within the digestive tract of the subject, during ingestion of the system by the subject.

Abstract: An arrangement and method for treating cardiac abnormalities and/or inconsistencies are provided. In particular, a fluid is introduced to a target area within a heart of a subject. Preferably, a volume of the target area which receives the fluid is less than a volume of the heart, and the volume of the target area which receives the fluid is independent from a manner of introducing the fluid to the target area. For example, the volume of the target area which receives the fluid is less than the volume of the heart regardless of whether the fluid is introduced systemically or locally. The arrangement may also include an energy source adapted to transmit energy, such as light, to at least one portion of the target area.
