TMS Medical Technologies offers the Samariton AED, which is biphasic, pediatric capable, fully automatic, easy to use, compliant to the new AHA standards and is software upgradeable. It is among the smallest and lightest in the market -- half the size of most AEDs and weighing 2 pounds. Samariton includes a rugged carry case and one Adult PadPak (a single disposable consisting of the pads and the battery). The single disposable has a shelf life of greater than three years and cuts down the time tracking expiration dates.
