摘要:
An apparatus is disclosed as part of a system for tracking and confirming delivery of a medicinal dose to a user. The apparatus includes a detector. The detector is secured to and communicatively coupled to the user and is capable of detecting a current flow through the user's body. The current flow is produced when the user makes contact with the apparatus. The apparatus includes at least two contact areas connected to a power source where a circuit and, hence, a current path is completed through the user's body as the user makes contact with the apparatus. The current flow is detected by the detector, which is coupled to the user. Also disclosed is an apparatus for tracking and confirming delivery of a medicinal dose to a user where the apparatus includes an acoustic detector. Upon loading the dose into a chamber an acoustic vibration is generated. The vibration is detected and correlated with a current flow that is produced when the user makes contact with the apparatus. The combined event of vibration detection and current flow detection confirms that the dose is loaded and the user is in contact with the apparatus and ready to receive the dose.

Aspects of systems include a data aggregating module configured to receive both continuous field tomography data and non-continuous field physiological data and produce an aggregated data product from these disparate types of data. Also provided are methods of using systems of the invention in a variety of different applications, including diagnostic and therapeutic applications. The systems and methods of the invention find use in a variety of different applications, such as cardiac related applications.
摘要:
Methods for evaluating motion of a tissue, such as of a cardiac location, e.g., heart wall, via electrical field tomography are provided. In the subject methods, an sensing element is stably associated with a tissue location of interest. Signals obtained from the sensing element are obtained to evaluate movement of the tissue location. Also provided are systems and devices for practicing the subject methods. In addition, innovative data displays and systems for producing the same are provided. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.

摘要:
Ingestible event markers comprising an identifier and an ingestible component are provided. The ingestible component may vary, where ingestible components of interest include osmotic ingestible components, liquid capsules, tablets, multi-layered ingestible component and multi-compartment ingestible components. In some instances, the identifier is mechanically stably associated with the ingestible component. Also provided are systems that include the ingestible event markers, as well as methods of using the ingestible event markers.
摘要:
Ingestible event marker systems that include an ingestible event marker (i.e., an IEM) and a personal signal receiver are provided. Embodiments of the IEM include an identifier, which may or may not be present in a physiologically acceptable carrier. The identifier is characterized by being activated upon contact with a target internal physiological site of a body, such as digestive tract internal target site. The personal signal receiver is configured to be associated with a physiological location, e.g., inside of or on the body, and to receive a signal the IEM. During use, the IEM broadcasts a signal which is received by the personal signal receiver.

摘要:
Methods of highly selective cardiac tissue stimulation and devices for practicing the same, e.g., implantable segmented electrode devices, are provided. The methods and devices provide a previously unavailable high phrenic nerve capture voltage paired with a low pacing capture voltage threshold. The subject methods and devices provide a number of benefits. For example, patients who previously would have been required to have their resynchronization device turned off due to phrenic nerve capture will now be able to reap the benefits of resynchronization therapy.

Minimally invasive deployable epicardial array devices are provided. The devices include deployable platform comprising two or more effectors, such as sensors and actuators, where the devices are configured to be deployed at an epicardial location via a minimally invasive, e.g., sub-xiphoid approach. In embodiments of the present invention, at least one area of the electrode patch is an electrical control area that comprises a series of effectors, e.g., sensors and/or electrodes. Other embodiments provide localized physical constraint and dynamic mechanical stimulation of the heart to effectuate physical and biological responses. Still other embodiments provide both of these functions. Also provided are methods of using the devices, as well as systems and kits that include the devices.
