The present invention relates to the use of triple monoamine reuptake inhibitors for the treatment of chronic pain. Also disclose herein are methods of treating a patient, comprising: providing a self-inflating expandable attenuation device, containing a medium which is transformable from a first, reduced volume to a second, expanded volume; positioning the attenuation device within the patient at a treatment site; and transforming the medium from the first volume to the second volume. The deck plate is constructed at least partially, or entirely, of a multi-layered printed circuit board for providing electrical pathways for communicating power and signals between electrical components mounted to the deck plate.
