<p>The guide wire (1) according to the present invention comprises a core (2); and a synthetic resin layer (3) for covering the outer surface of the core (2) and containing fluororesin. Therefore, an excellent slidability in the blood vessel and the catheter can be obtained and a proper sliding performance can be obtained with which the guide wire can be assuredly held with the hand with a vital adaptability permanently exhibited. Furthermore, the guide wire (1) according to the present invention comprises: a core (2); a layer (4) for covering the outer surface of the core (2) and having contrast characteristics; and a synthetic resin layer (3) for covering the outer surface of the layer (4) having the contrast characteristics and containing fluororesin. Therefore, the position of the overall body of the guide wire can be easily confirmed under the X-ray contrast. In particular, the position of the front portion of the guide wire can be easily confirmed. Therefore, the handling facility can be improved. Since the core (2) is made of ultraelastic metal, any viciousness due to the bending operation can be prevented and its flexibility can be maintained. Therefore, the guide wire (1) can be easily inserted into the blood vessel with a good correspondence maintained even the blood vessel meanders.</p> |
