Description
このカテーテルの遠位端は、中央管12が側部管14、16の端部を越えてある長さだけ遠位へ突出するように、側部管14、16の遠位端をまず取り除くことによって形成されている。図2には、この装置の遠位端における相対的な長さが変わるかもしれないということを理解すべきであるが、管12、14、16のほぼ相対的な長さが示されている。側部管14、16の遠位端は、少なくとも一方の側部管が、そして好ましくは両方の側部管が、図4及び図5に表されたように斜めの出口24、26で終わるように、加熱あるいは成形によって加工されている。斜めの出口24、26は、管腔20、22の遠位部分の中に適切に方位付けられたマンドレルを配置し、次いで、熱可塑性PEBAXあるいは他の適当なポリマーを溶融させて充填することで、これらの管の遠位開口を閉鎖し、一方、カテーテルの長手軸に対して所望の射出角で案内ワイヤの遠位端を外側へ案内することになる傾斜部(ランプ)28、30がある側部開口24、26を形成することによって、形成することができる。図6Aには、側部管16の管腔を通って延びた案内ワイヤ32が示されており、この案内ワイヤ32は、特定の射出角で斜めの出口26から外側へ突出している。
図6Bは、図6Aに類似しているが、装置の遠位先端の好ましい寸法的細部が含まれている点と、約25度の射出角が表されている点で、図6Aとは異なっている。図6Bから、カテーテルが前進させられて所望の分枝の中へそれ自体が導かれないようなときには、出口26をその斜めの分枝への入口に方位付けるために、そのカテーテルは長手方向に操作されることもある、ということが認識されるであろう。傾斜部24、26は、案内ワイヤの遠位端が出口で引っかからないことを保証するために、これらの傾斜部とのスムーズな係合がもたらされるように構成すべきである。さらに、約25度の射出角が好ましいものとして図示されているが、この射出角は約1度〜約45度が含まれる合理的に受け入れることのできる範囲内で変えることができる、ということを認識すべきである。
