An anode for use in a high voltage electrolytic capacitor is provided. The anode contains a sintered porous pellet and a leadwire extending therefrom in a longitudinal direction. The pellet is multi-layered to the extent that it contains at least a first layer positioned adjacent to a second layer, both of which extend along the length of the anode. The anode leadwire is embedded within the first layer. For this reason, the first layer has a thickness greater than that of the leadwire. Nevertheless, the use of a separate and distinct second layer adjacent to the first layer can allow each of the layers to be independently pressed using a multi-sided compaction device so that the properties of the anode are not significantly impacted by the presence of the relatively large anode leadwire.

A system for analyzing the energy delivered to ECG device from the defibrillator is disclosed. The system includes an energy analyzing unit configured to measure the energy delivered to the ECG device from the defibrillator, wherein the energy gets diverted to the ECG device during operation of the defibrillator; and a presentation unit capable of presenting the measured energy in the ECG device.

In various embodiments, the presently described methods, apparatus, and systems can facilitate decreasing a boot time of a medical device, e.g., an amount of time between when a medical device or system is first turned on or powered on and when the medical device or system is ready to perform its intended function. In some embodiments, the present disclosure can also facilitate conducting tests on the functionality of various operational circuits shortly or immediately after the device/system has been activated. In some cases, the emergency medical devices/systems can report on the status or functionality of operational circuits even before the emergency medical device is fully booted up and ready to perform some or all of its intended functions.

A hermetically sealed capacitor and method of manufacturing are provided. The hermetically sealed capacitor includes an anode element having an anode wire and a feed through barrel, a cathode element, a first case portion having a first opening portion and a second case portion having a second opening portion. The first and second opening portions form an opening configured to mate with the feed through barrel. The first opening portion may include a slot portion configured to receive the feed through barrel. The hermetically sealed capacitor may also include electrolytic solution disposed between the first and second case portions.

An energy supplying component (100) includes a plurality of power sources (161, 171, 181, 191) and at least one switch (163, 165, 167, 173, 175, 177, 183, 185, 187, 193, 195, 197). Each power source of the plurality of power sources is configured to output a defined energy level. The at least one switch is configured to reversibly combine two or more power sources of the plurality of power sources for enabling the energy supplying component to supply requested energy at one or both of a needed voltage or a needed current.

Methods and apparatus to form biocompatible energization elements are described. In some examples, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a biocompatible material. In some examples, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.

A system including a medical device is provided. The medical device includes at least one sensor configured to acquire first data descriptive of a patient, first memory storing a plurality of templates, and at least one processor coupled to the at least one sensor and the first memory. The at least one processor is configured to identify a first template of the plurality of templates that is similar to the first data, to determine first difference data based on the first template and the first data, and to store the first difference data in association with the first template. The system may further include the programmable device.

An implantable medical device includes a low-power circuit, a high-power circuit, and a dual-cell power source. The power source is coupled to a dual-transformer such that each cell is connected to only one of the transformers. Each transformer includes multiple windings and each of the windings is coupled to a capacitor, and the capacitors are all connected in a series configuration. The low power circuit is coupled to the power source and issues a control signal to control the delivery of charge from the power source to the plurality of capacitors through the first and second transformers.

A system, such as an IMD system, includes a tissue conductance communication (TCC) transmitter configured to generate a beacon signal by generating a carrier signal and modulating a first property of the carrier signal according to a first type of modulation. The TCC transmitter is configured to generate a data signal subsequent to the beacon signal by generating the carrier signal and modulating a second property of the carrier signal different than the first property according to a second type of modulation different than the first type of modulation.

An intra cardiac device is disclosed. The device comprises means for transforming kinetic energy from heart tissue movement into electrical energy in use, from which electrical energy information in respect of heart function is obtainable. Furthermore, a system is disclosed, comprising one such intra cardiac device and at least one receiver, wherein the intra cardiac device comprises means of communication, through which said at least one device communicates with the receiver(s) wirelessly. In this way energy from heart movement provides self contained intra cardiac devices for conveniently monitoring or stimulating a patient's heart.
