An apparatus includes a semiconductor package, a radio receiver and a processor. The non-crosslinked polymer includes an ethylene unit andor propylene unit, and an unsaturated carboxylic acid unit having a carboxyl group esterified by a polyalkylene glycol having one terminal hydroxyl group protected. The method uses an apparatus including an electrode, and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. A biasing mechanism biases against the main body and the sleeve and is preferably disposed in the external groove and the recess.
