PCI Guide Wires are intended to facilitate the placement of balloon dilatation catheters during percutaneous coronary intervention (PCI) and percutaneous transluminal angioplasty (PTA). The PCI Guide Wires are not intended for use in the neurovasculature.

Device Story

MINAMO blue and MINAMO viola are catheter guide wires used to facilitate balloon dilatation catheter placement during PCI and PTA procedures. The device consists of a hybrid stainless steel and nitinol core wire, a stainless steel distal inner rope coil, and a radiopaque platinum-nickel/stainless steel outer coil. The distal tip is radiopaque for X-ray fluoroscopic visualization. The device is operated by a physician in a clinical setting (e.g., cath lab). The guide wire is inserted into the vasculature to navigate to the target site, providing a track for the balloon catheter. The device benefits patients by enabling precise delivery of interventional tools to coronary or peripheral lesions. Some models include a shaping device to assist in distal tip configuration.

## Description:

The basic structure of the MINAMO blue / viola consists of a hybrid stainless steel and nitinol (Ni-Ti) core wire, with a stainless steel distal inner rope coil. Surrounding the inner rope coil and the distal core wire is a radiopaque platinum nickel / stainless steel outer coil. The outer and inner coils are soldered to the tapered core wire. A similar coil design is used with other ASAHI guide wires, such as the predicate MINAMO (K190176). In addition, coatings are applied on the surface of the product. The coil portion is coated with a silicone and hydrophilic coating. The proximal side of the core wire is coated with PFA, silicone and PTFE.

The nominal outer diameter of the MINAMO is 0.36 mm. The devices are available in three lengths: 190 cm, 235 cm and 300 cm.

The MINAMO blue / viola radiopaque distal tip enables the user to view the position of the tip under X-ray fluoroscopy.

All sizes are available with a straight, pre-shape, and J-shape design.

### Accessory

Some model of the MINAMO blue / viola are packaged with a shaping device. The shaping device can be used to facilitate shaping distal end of the guide wire.
