Abstract: A system and method for improving heart contractions during a heart function cycle (heartbeat) of a patient requires detecting a local electrical event (depolarization) during the cycle. This local electrical event is then used to trigger a stimulation interval ?t at a time t0. Importantly, the stimulation interval ?t is set to end at a time t1 during the absolute refractory period of the heart function cycle. At the time t1, a stimulator is triggered to stimulate a local sympathetic nerve on the epicardial surface of the heart. With this stimulation the sympathetic nerve secretes norepinephrine to improve a subsequent contraction of the heart.

Abstract: The present invention uses one or more radiation-emitting devices in combination with a topical radiation block to ablate the skin and remove topographic variations in the skin surface. The energy pathway may be guided by a computer. The device might also include a treatment plate or window to be placed against the skin in order to flatten the skin surface during treatment. The purpose of the topical radiation block is to manage the areas to which the radiation is applied to the skin by allowing the radiation to reach some portions of the skin, while limiting or preventing the radiation from reaching other portions of the skin. In the case of atrophic scarring, for example, the block may be deposited selectively into the atrophic indentations, such that the block limits or prevents the radiation from reaching (and thereby ablating) the indentations, but allows the radiation to reach (and thereby ablate) the surrounding skin tissue.
