The complications of mechanical lithotripsy include a trapped basket surrounding the stone, fracture of the basket wires or the main operation wire, malfunction of the mechanical lithotriptor crank handle, and ductal injury [1,2]. Impaction of a basket with a captured stone inside occurs occasionally not only during mechanical lithotripsy but also during removal of small stones with non-lithotr...

B2223 High Temperature Superconductor (HTSC) has been prepared as a pellet by solid state reaction. Then, HTSC wires were fabricated from the prepared superconductor using powder in tube (PIT) method utilizing silver as the tube material. Superconductor powder was packed in the pure silver tube of about 4.5 mm diameter, and 50mm long. The prepared wires are of three types; with monofilament MOF...
