Latest Patents

One of Shemer's latest patents is titled "Modulation of intracellular calcium concentration using non-excitatory electrical signals applied to the tissue." This invention involves a method and device for modulating intracellular calcium concentration in biological tissue. A stimulation probe is applied to the tissue, where a non-excitatory stimulation pulse is generated and conveyed to the probe. In a specific embodiment concerning cardiac tissue, the probe is applied to a patient's heart, receiving signals from sensors responsive to the patient's cardiac muscle activity. A non-excitatory stimulation pulse is then generated in response to this signal and conveyed to the stimulation probe.

Another significant patent is "Pacing with hemodynamic enhancement." This apparatus is designed for heart pacing with improved hemodynamics. It includes one or more electrodes that convey electrical signals to respective cardiac muscle segments. The signal generation circuitry applies an extended pacing signal, which has an overall duration greater than three times a chronaxie time, to the electrodes. The signal comprises a train of biphasic pulses, with an amplitude at least three times greater than the threshold for pacing the heart, but not sufficient for cardioversion.
