PROBLEM TO BE SOLVED: To easily guide and indwell medical equipment into a coronary artery from outside a heart.SOLUTION: A cardiac medical equipment guiding instrument includes: an annular transverse part disposed over the whole periphery in a position in which the transverse part covers the circumflex and the right coronary artery C traveling along the circumferential direction on the surface of a heart A a longitudinal part having both ends connected to the transverse part, and disposed in a position in which the longitudinal part covers the anterior descending artery D and a peripheral part E such that the longitudinal part surrounds the cardiac apex B side and an introduction part connected to either one of the longitudinal part and the transverse part. The transverse part, the longitudinal part, and the introduction part are each formed in a tube shape through which medical equipment can be inserted thereinside, at least the transverse part and the longitudinal part are formed of an expandable and contractible material, the transverse part and the longitudinal part are covered on the outer face of the heart A from the cardiac apex B side in a contracted state, and the cardiac medical equipment guiding instrument has size in which the cardiac medical equipment guiding instrument is stuck to the circumflex and the right coronary artery C, the anterior descending artery D, and the peripheral part E when expanded by a fluid pressure.COPYRIGHT: (C)2015,JPO&INPIT【課題】医療機器を心臓の外側から冠動脈に容易に誘導および留置する。【解決手段】心臓Aの表面を周方向に沿って走行する回旋枝および右冠状動脈Cを被覆する位置に、全周にわたって配置される環状の横断部と、該横断部に両端が接続され、前下降枝Dおよび末梢部Eを被覆する位置に、心尖B側を取り囲むように配置される縦断部と、縦断部または横断部のいずれかに接続する導入部とを備え、横断部、縦断部、導入部が、内部に医療機器を挿通可能な管状に構成されるとともに少なくとも横断部、縦断部が、拡張および収縮可能な材質により構成され、横断部、縦断部が、収縮した状態で、心尖B側から心臓Aの外面に被せられ、かつ、流体圧によって拡張させられたときに、回旋枝および右冠状動脈C、前下降枝D、末梢部Eに密着させられる寸法を有する心臓用医療機器誘導具を提供する。【選択図】図3
