Abstract
A stimulation system and method includes a stimulation driver which drives bio-interface electrodes with a pulse shape which transmits more than ⅔ of the pulse's total energy before ⅓ of the pulse's total duration has elapsed.
Claims20
A stimulation system comprising:
- a stimulation driver which drives bio-interface electrodes with a pulse shape which transmits more than ⅔ of the pulse's total energy before ⅓ of the pulse's total duration has elapsed.
The method of claim 11 further comprising
- driving bio-interface electrodes with a pulse shape which transmits more than ⅔ of the pulse's total energy before ⅓ of the pulse's total duration has elapsed.
The method of claim 11, wherein said more than 90% of the pulse's total energy is transferred before 10% of the pulse's total duration has elapsed.
A stimulation method comprising:
- intermittently driving bio-interface electrodes, which are in contact with tissue, with a pulse by a stimulation driver;
- wherein said stimulation driver has a source impedance which has less than half the magnitude of impedance seen at said electrodes when said pulse has risen halfway to its peak voltage.
A stimulation method comprising:
- intermittently driving bio-interface electrodes, which are in contact with tissue, with a pulse;
- wherein said pulse has a shape which is optimized for transfer of energy through a series capacitor.
