A new coronary angioplasty guidewire has been brought to the North American market. This hybrid guidewire combines several technologies. It is produced by the company Asahi Intecc (Japan), which, in my opinion, is a guarantee of success. It is called Minamo and it has a three-piece coaxial core. These pieces are, from proximal to distal: a round stainless steel core, followed by a tapered nitinol core, and most distally, a stainless steel round press core. This end segment is surrounded by a 170 mm coil, with the most distal 30 mm containing braided wires with ACT One technology. As is well known, this section with ACT One technology allows the preshaped curve to retain its shape for a longer time and be reshaped as many times as necessary without breaking the guidewire. It can be preshaped easily with a special needle, and even it this is done several times, it forms a perfect J curve without distortion.
The Minamo guide wire is suitable for everyday use in most interventional procedures. It has a tip load of 0.5 gf. The most distal 25 mm of the tip is silicone-coated, and the remainder is hydrophilic-coated.
