1. A method of treating the sacroiliac region of a patient'"'"'s body by delivering energy, comprising the steps of:

  • providing a probe having an active portion at a distal end thereof, the active portion having at least two regions of electrical discontinuity which result in a region of increased current density about the probe when energy is delivered to the probe, the active portion slidably disposed within an insulating member such that a position of the active portion relative to the insulating member may be altered;

    inserting the probe into a patient'"'"'s body proximate a sacrum and positioning the probe at a target site external to a sacroiliac joint;

    delivering energy to the probe to treat tissue within the target site; and

    moving the insulating member along a length of the active portion during the step of delivering energy such that a position of at least one of the regions of electrical discontinuity is adjusted, wherein the active portion of the probe creates a strip lesion during a single energy delivery step.
