Radifocus Guide Wire M

Guide Wire

Product Overview

Design Structure


  • Rigidity of the shaft is different depending on the thickness of core wire.
    ・The bigger the core wire is, more rigid the shaft is.
  • The shaft of stiff wire is twice as rigid as that of standard wire.

Tip shape

Straight-type guide wires can be advanced linearly, but may damage blood vessels.
With high selectivity, Angle-type guide wires are easily inserted into sheaths, but may damage blood vessels compared with the J-shape guide wires.
J-shape is most common, which prevents damages to vascular intima and entry into small vessels and guides a catheter safely.
