Combination therapy including peripheral nerve field stimulation

An implantable medical device system comprising:

• at least one implantable medical device, wherein the at least one implantable medical device comprises a single implantable medical device configured to deliver a first electrical stimulation therapy to a patient via a first implantable element and deliver a second electrical stimulation therapy to the patient via a second implantable element in combination with delivery of the first electrical stimulation therapy or more than one implantable medical devices configured to collectively deliver the first electrical stimulation therapy to the patient via the first implantable element and deliver the second electrical stimulation therapy to the patient via the second implantable element in combination with delivery of the first electrical stimulation therapy;
• and
• a processor configured to control the at least one implantable medical device to deliver, via the first implantable element, the first electrical stimulation therapy to the patient according to a duty cycle throughout a period of time such that the first electrical stimulation therapy delivery is cycled on and off more than once during the period of time, and control the at least one implantable medical device to deliver the second electrical stimulation therapy continuously and according to a selected frequency throughout the period of time, via the second implantable element, such that the first electrical stimulation therapy and the second electrical stimulation therapy are both delivered during a first portion of the period of time when the first electrical stimulation therapy is cycled on and the second electrical stimulation therapy is delivered but the first electrical stimulation therapy is not delivered during a second portion of the period of time when the first electrical stimulation therapy is cycled off, wherein one of the first electrical stimulation therapy and the second electrical stimulation therapy comprises peripheral nerve field stimulation therapy, and another of the first electrical stimulation therapy and the second electrical stimulation therapy comprises an electrical stimulation therapy configured to treat pain to the patient in combination with the peripheral nerve field stimulation.
