Typical characteristics of guidewires. (A, upper) Structure of a TRUwire. The guidewire is structurally divided into a shaft area and a tip area. The hydrophilic coating is mainly applied for the tip area. (B, lower) Scanning electron microscopy (ULTRA PLUS; zeiss group., Land Baden-Württemberg, Germany) cross-section images of guidewires (× 100, upper line) and hydrophilic coating thickness (× 3,000, lower line): TRUwire, VisiGlide 2, Jagwire Revolusion, Acrobat II, MICHISUJI (Left to right). Spiral coiled spring structure was noted on all guidewires except Jagwire.
