PROBLEM TO BE SOLVED: To provide a guide wire introduction device for deploying an opening for introducing the guide wire in the pericardium by just leading a micro portion near a distal end into the pericardium.SOLUTION: The guide wire introduction device includes: a cylindrical body 2 having a through-hole 2a opened at a distal end side in the longitudinal direction and allowing the guide wire to penetrate therethrough a non-sharp distal end 3 that is provided at the distal end of the body 2 and cannot penetrate through the pericardium by just pressing and a hook section 5 having a pointed end 5a that extends radially outward a lateral face of the body 2 at a proximal side with respect to the distal end 3 and can penetrate through the pericardium coming into contact from the lateral side.COPYRIGHT: (C)2014,JPO&INPIT【課題】心膜内に先端部近傍の微小部分を進入させるだけで、ガイドワイヤを心嚢内に導入するための開口を心嚢内に配置するガイドワイヤ導入装置を提供する。【解決手段】長手方向の先端側に開口しガイドワイヤを貫通可能な貫通孔2aを有する筒状の本体2と、該本体2の先端に設けられ、押し付けただけでは心膜を貫通できない非鋭利な先端部3と、該先端部3よりも基端側の本体2の側面に半径方向外方に延びて、側方から接触する心膜を貫通可能な尖端5aを有するフック状の引掛部5とを備える。【選択図】図1
