In embodiments, data corresponding to an object is determined from symbology. The electrostatic-dischargeimpedance-matching circuit includes at least one shunt circuit operable to shunt current related to an over-voltage condition and at least one series element operably coupled to the shunt element. Upon insertion through the narrow openings of the pelvis, the frame is compressed, and upon delivery at the site, the frame is expanded, and is designed to anchor to the surrounding anatomical structures.
