Apparatus, methods, computer program products, systems and circuits are provided that allow for persistent uplink and downlink resource allocations. The microsurgical instrument may be fitted with infusion, aspiration, or illumination sources, and these sources are directed to the surgical site in proximity to the scraping edge, the abrasive particles on the edge scrape membranes to remove tissue at the surgical site. Heat causes the substance to transform into a gaseous state due to the transfer of thermal energy from the heat source to the substance. With the above configuration, a signal can be transmitted at a high speed with a low voltage amplitude and low power consumption.
