Abstract An apparatus is described that comprises an electrode, a waveform generator connected to the electrode, and a 5 controller. The controller is configured to control the waveform generator to first apply a first high frequency alternating current (HFAC) to a nerve through the electrode, the first HFAC having a first amplitude and a first frequency, the combination of the first amplitude 10 and the first frequency being configured to produce a conduction block in the nerve, where the conduction block blocks transmission of signals through the nerves. The controller is also configured to control the waveform generator to then apply a second HFAC to the nerve, the 15 second HFAC having a second amplitude and a second frequency, the combination of the second amplitude and the second frequency being configured to not produce a nerve conduction block in the nerve, the combination of the second amplitude and the second frequency being configured 20 to prevent the occurrence of an onset condition in the nerve upon the application of a third HFAC sufficient to produce a conduction block in the nerve. The controller is also configured to control the waveform generator to then apply the third HFAC to the nerve, the third HFAC having a 25 third amplitude and a third frequency, the combination of the third amplitude and the third frequency being configured to produce a conduction block in the nerve. 6414989_1 (GHMatters) P83987.AU.2 MELANIEE |
