1. A therapy system for treating a patient's pain, comprising: a pulse generator coupled to a signal delivery element to transmit multiple electrical stimulation signals to the signal delivery element, the signal delivery element comprising a lead body including one or more electrodes; and a machine-readable medium within the pulse generator, the machine-readable medium containing instructions that, when executed, cause the pulse generator to transmit the multiple electrical stimulation signals to multiple neurons of a target sensory neural population via the signal delivery element, wherein the multiple electrical stimulation signals have a target stimulation frequency that is in a range from 3.0 kHz to 10 kHz, and wherein the multiple electrical stimulation signals produce an asynchronous sensory neuron response.
