AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1, 2 and 15 is confirmed.
Claims 16 and 17 are cancelled.
Claims 3-14 and 18-59 were not reexamined.
At the time of issuance and publication of this certificate, the patent remains subject to pending reexamination control number 90/013,483 filed Apr. 1, 2015. The claim content of the patent may be subsequently revised if a reexamination certificate issues from the reexamination proceeding.
1. A method for applying electrotherapy to a patient through electrodes connected to an energy source, the method comprising the following steps:
charging the energy source to an initial level;
discharging the energy source across the electrodes to deliver electrical energy to the patient in a multiphasic waveform;
monitoring a patient-dependent electrical parameter during the discharging step;
shaping the waveform of the delivered electrical energy based on a value of the monitored electrical parameter, wherein the relative duration of the phases of the multiphasic waveform is dependent on the value of the monitored electrical parameter.
