Description
上記のように、連結領域14の距離が比較的短いので、連結装置を互いに関連させて動かすのに好都合である。また一方、カテーテル10を固定されたワイヤガイド11の遠位先端部25に向けて前進させることにより、又は、ワイヤガイドがカテーテルを通って側部アクセスポート15/連結領域14を抜け出るまでワイヤガイドを引き戻すことにより、又は、カテーテル前進移動とワイヤガイドの引き抜きの組み合わせにより、その他、体内に留置されたワイヤを介して次の装置によるアクセスをやり易くするためにワイヤガイドを施術部位内(例えば管)に残留させるこのようなすべての好適なやり方により、装置を互いに連結解除するのに十分な距離は確保されている。
