THERAPEUTIC METHOD WITH PAIN RELIEF
First Claim
1. A method of blocking undesirable side effect activation of electrically excitable tissue wherein the undesirable side effect is pain, the method comprising the steps of:
- therapeutically activating tissue at a first predetermined site within a patient'"'"'s body; and
blocking activation of tissue or conduction of action potentials at a second predetermined site within the patient'"'"'s body by applying high frequency stimulation or one or more direct current pulses or both high frequency stimulation and one or more direct current pulses at or near the second site.

Abstract
A desired effect is produced by therapeutically activating tissue at a first site within a patient'"'"'s body and a corresponding undesired side effect is reduced by blocking activation of tissue or conduction of action potentials at a second site within the patient'"'"'s body by applying high frequency stimulation and/or direct current pulses at or near the second site. Timex varying DC pulses may be used before or after a high frequency blocking signal. The high frequency stimulation may begin before and continue during the therapeutic activation. The high frequency stimulation may begin with a relatively low amplitude, and the amplitude may be gradually increased. The desired effect may be defibrillation of the patient'"'"'s atria or defibrillation of the patient'"'"'s ventricles, and the undesired side effect may be pain.

13. A method of blocking undesirable side effect activation of electrically excitable tissue, wherein such undesirable side effect activation includes pain, the method comprising the steps of:
-
therapeutically activating tissue at a first predetermined site within a patient'"'"'s body by applying low frequency stimulation at or near the first predetermined site; and
blocking activation of tissue or conduction of action potentials at a second predetermined site within the patients body by applying high frequency stimulation or one or more direct current pulses or both high frequency stimulation and one or more direct current pulses at or near the second site such that the high frequency stimulation and/or the direct current pulses prevent the low frequency stimulation applied at the first site from activating the electrically excitable tissue, or causing conduction of action potentials, at the second site. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method of stimulating tissue within a patient'"'"'s body while blocking undesirable side effect activation of electrically excitable tissue, wherein such undesirable side effect activation includes pain, the method comprising the steps of:
-
implanting a tissue stimulating system in the patient'"'"'s body with a first electrode at or near a first predetermined site within the patient'"'"'s body and a second electrode at or near a second predetermined site within the patient'"'"'s body;
therapeutically activating tissue at the first predetermined site within a patient'"'"'s body by applying low frequency stimulation at or near the first predetermined site with the first electrode; and
blocking activation of tissue or conduction of action potentials at a second predetermined site within the patient'"'"'s body by applying high frequency stimulation or one or more direct current pulses or both high frequency stimulation and one or more direct current pulses at or near the second site with the second electrode such that the high frequency stimulation and/or the direct current pulses prevent the low frequency stimulation applied at the first site from activating the electrically excitable tissue, or causing conduction of action potentials, at the second site. - View Dependent Claims (23, 24, 25, 26, 27)
