Percutaneous Electrode Array Biowave's patented percutaneous electrode array (PEA) is a microneedle patch technology that facilitates the delivery of high frequency electrical feed signals through the skin directly into deep tissue encompassing the pain site. The PEA eliminates impedance and capacitance issues associated with skin. Patented Neuromodulation Signal Technology The patented electrical signal technology is comprised of a premixed set of high frequency wave forms which are delivered to each electrode. As the feed signals pass through each electrode which are placed directly over points of pain, polarized structures including nerve fiber membranes, that lie within a two inch volume of tissue beneath each electrode, act like nonlinear devices, causing the feed signals to further multiply. The result is a new spectrum of signals including the formation of a low frequency electric field, which is believed to interrupt transmission of pain impulses by preventing action potential propagation along pain fibers – a similar mechanism to local chemical anesthesia, except without any deleterious side effects. See both diagrams to the right. The use of different sized pads as well as the use of a percutaneous electrode in combination with a non-invasive electrode allow the resulting electric field to be focused in the volume of tissue surrounding and beneath the PEA (see top diagram to the right). The size of the volume of tissue affected can be changed and is dependent upon PEA placement, geometry and materials, as well as the intensity of the feed signals. The sensation felt by the patient is a comfortable pressure and tingling sensation without muscle twitching or side effects that are common to other electrotherapy devices. Biowave also utilizes its patented SmartPAD™ technology in all of its electrodes. The SmartPAD™ technology is a continuous closed loop monitoring and adjustment of the delivery of the electrical signal technology. The SmartPAD™ technology ensures the accurate and safe delivery of therapeutic energy into deep tissue. |
