Medical device for navigation through anatomy

Medical devices equipped with the tubular component (130) provided with the guide wire (100) or the slot, or its both sides for going on the inside of human body structure. The guide wire (100) may have a core wire (150). The above-mentioned medical devices may have a coil (200, 345, 600, 1141, 1143, 1243, 2238, 2266, 2441). In a coil (200, 345, 600, 1141, 1143, 1243, 2238, 2266, 2441), The marker coil (200) which carried out the edge volume of the wire which has an un-circular section, and the 近心 coil (1141-1143, 1243) which it extended-coil-tipped (300), and was soldered, or was pasted up are contained. In the connection part (140) to a tubular component (130), the core wire (150) may have a level difference (1551-2151, 2152), an upheaval part (1351), and a taper part (1253), and may have a plate-like portion (1057) in the tip chip (257). Radiation an unpenetrated material (801, 802) may be arranged, and heat treatment may be given to the inside of a tubular component (130) so that a tip chip (138) may be can be fabricated. An another tubular component (730-2062, 2130, 2162, 2439) or coil (200, 345, 600, 1141, 1143, 1243, 2238, 2266, 2441), You may be arranged so that it may be lined in the shape of the same mind, or a row, and flexibility can be improved, radiopacity can be given, friction can be reduced, material can be reduced, or a manufacturing cost can be made low. The tubular component (130, 730, 2062, 2130, 2162, 2439) has been cuted off the corners enough (231), or the path may be small continuously or gradually. The slot (135) may constitute the group (235-1635) like the group (1635) which consists of three slots, for example. Moreover, in order to obtain a chip compressible operational, the slot (135) may have uniform length and may have un-uniform length.
