First Claim
Patent Images
1. A multiphasic pulse generator, comprising:
- a plurality of subsystems wherein each subsystem has a power source and an energy reservoir;
at least one of the plurality of subsystems generates a first phase of a pulse that has a shape and is one of a positive phase of the pulse and a negative phase of the pulse;
at least one of the plurality of subsystems generates a second phase of the pulse that has a shape and is an opposite polarity phase to the first phase of the pulse; and
a switch element that switches between the subsystem that generates the first phase of the pulse and the subsystem that generates the second phase of the pulse to generate a therapeutic pulse having at least one positive phase and at least one negative phase.

10. A method for generating a therapeutic pulse, comprising:
-
providing a plurality of subsystems wherein each subsystem has a power source and an energy reservoir; using one of the plurality of subsystems to generate one or more positive phases for a pulse; using a different one of the plurality of subsystems to generate one or more negative phases for a pulse using a second power source and a second energy reservoir; and switching between the one or more positive phases and the one or more negative phases to generate a therapeutic pulse having at least one positive phase and at least one negative phase. - View Dependent Claims (11, 12, 13, 14, 15, 16)
