- 分岐血管を備え、かつ長手方向軸を有する血管内で展開させるカテーテルシステムにおいて、
長尺状をなすカテーテル軸を有するカテーテルであって、同カテーテル軸はその長さ方向に延び、かつ主ガイドワイヤが挿通される主ガイドワイヤ内腔を有し、前記カテーテル軸の先端部の外周面には膨張可能なバルーンが配置されてステント保持領域が画成され、前記ステント保持領域より基端側のカテーテル軸の一部が少なくとも一つの湾曲部を画成し、前記少なくとも一つの湾曲部が前記血管の長手方向軸周りに螺旋状経路を形成し、カテーテルはさらに長尺状の側方分岐ガイドワイヤハウジングと側方分岐ガイドワイヤとを有し、側方分岐ガイドワイヤハウジングはステント保持領域に設けられて、分岐血管内に延び、前記側方分岐ガイドワイヤはその長さ方向全体にわたって延びて、分岐血管に連通する側方分岐ガイドワイヤ内腔を画成し、前記側方分岐ガイドワイヤが、主ガイドワイヤから離間して主ガイドワイヤと絡み合うことなくカーテル軸に沿ってその外周面上を螺旋状に延びたのち分岐ガイドワイヤ内腔を挿通して分岐血管に延びるカテーテルシステム。 - 前記螺旋状経路は血管の長手方向軸の中心に延びる複数個の湾曲部よりなる請求項1記載のシステム。
- 前記カテーテル軸の少なくとも一部が編組み材よりなる請求項1記載のシステム。
- 前記カテーテル軸は湾曲部の近傍において主ガイドワイヤ内腔と連通する交換ポートを構成し、主ガイドワイヤが交換ポートを挿通して主ガイドワイヤ内腔内に延びる、請求項1記載のシステム。
- 前記側方分岐ガイドワイヤハウジングの先端部は可膨張バルーンから斜状に延び、前記側方分岐ガイドワイヤハウジングがバンドをさらに備え、同バンドが側方分岐ガイドワイヤハウジングの先端部の周りに配置され、前記バンドは膨張状態と非膨張状態とに変化可能であり、バンドは非膨張状態においてはリング状をなし、膨張状態においては頂部と底部とを有する円錐状をなし、頂部の直径が底部の直径よりも大きいことにより側方分岐ガイドワイヤが主ガイドワイヤとは離れた状状態に保持される請求項1に記載のシステム。
- バンド膨張内腔をさらに備え、バンドがこのバンド膨張内腔に連通して膨張流体を受容するよう構成され、前記膨張状態においてバンドには膨張流体が充填され、前記非膨張状態においてバンドから膨張流体が流出されリング形状となる、請求項5記載のシステム。
- 前記カテーテル軸は断面視において中心軸を中心に環状をなす中空状の本体を備え、本体は中心軸を中心に環状をなす内縁部と、同内縁部から半径方向外方に連続する外縁部とを備え、外縁部にはカテーテル軸の外周面上で周方向において離間して外方へ突出する複数の外縁ピークと、隣接する外縁ピークを連結する外縁トラフとが形成され、複数の外縁ピークは複数の外縁トラフよりも中心軸から離間した距離にある請求項1記載のシステム。
- 前記内縁部が同内縁部から外方に切欠かれた複数の内縁ピーク及び同内縁ピーク間に位置する内縁トラフを備え、前記ピークはトラフよりもカテーテル軸の長手方向軸からの径方向距離が大きく、前記内縁部の各内縁ピークが外縁部の外縁ピークに径方向において対応し、さらに内縁部の内縁トラフが外縁部の外縁トラフに径方向において対応する、請求項7記載のシステム。
- 前記外縁ピークが支持体を備え、この支持体がカテーテル軸の本体のピーク内全体にわたって延び前記支持体が本体の長手方向軸に略平行である請求項7記載のシステム。
- 前記本体が第1の材料をよりなり、前記支持体が第2の材料よりなり、前記第1の材料が前記第2の材料より可撓性に富む、請求項9記載のシステム。
