  • Smooth muscle electrical stimulation based on entrainment of intracellular calcium ion oscillations
    Patent number: 10610685
    Abstract: Methods, systems, and apparatus for electrically stimulating a smooth muscle. The method includes generating a continuous pulse train signal having pulses and pulse intervals between the pulses, the pulses and the pulse intervals being generated at a pulse frequency. The method also includes modulating the continuous pulse train signal at a modulation frequency to match dynamics of intracellular calcium ion oscillations in the smooth muscle. The method also includes entraining a group of cells of the smooth muscle by applying the modulated continuous pulse train signal to the group of cells of the smooth muscle to increase an oscillation frequency of the calcium ion oscillations.
