Abstract
【解決手段】複数の安定形体を持つ医療装置において、相互連結された複数のセル64を有し、各セルは所定のセル構造を有し、これらのセルは、複数の安定形体を持つ多安定ばねシステムの形態のセル構造を形成するように相互連結された比較的剛性の区分52、66及び比較的可撓性の区分54、68を含む、医療装置を提供する。セル構造は、二つの安定形体を持つ双安定構造であってもよく、またセルは、半径方向に差し向けられた均等な力を加えることによって前記装置を二つの安定形体間で切り換えることができるように形成されており且つ構成されていてもよい。非拡張形体50及び一杯に拡張させた形体60を含む二つ又はそれ以上の形体を持つ管状ステントとして形成されており、一杯に拡張させた形体の前記ステントの直径は、非拡張形体の前記ステントの直径以上であってもよい。

Description
この構造は、なんらかの外部手段によってカテーテル上に保持しなければならない。この種の一例は、ステントをその自然の形態まで展開しなければならないときに取り除かれる送出シースによって収縮状態に保持されるステントである。
これらの自動膨張ステントの欠点は、送出シースを必要とし、挿入直径が大きくなるということである。更に、シースの取り出しにはシース引っ込め機構が必要とされ、これを基端で操作しなければならない。
幾つかのステントの別の欠点は、正のばね率(spring rate)である。これ
は、高いバルーン圧力によってしか更に拡張させることができないということを意味する。
例えば、ジョンソン&ジョンソン・インターベンションシステムズ社が製造しているパルマーシャズ(Palmaz−Schatz)ステントのユニットセル又はプログレッシブ・アンジオプラスティシステムズ社が製造しているACTワン・コロナリーステントは、その畳まれた状態において平らな矩形形状を有し、その拡張状態において或る程度菱形形状の形態を有し、ほぼ直線的なストラット(パルマーシャズ)又は成る程度湾曲したストラット(ACTワン)を含む。
特定の臨界直径以下では、本発明のステントは、更に、安定した最小直径にスナップ作用で移行し、かくして、萎ませたバルーンを、挿入直径をできるだけ小さくして、カテーテルの表面上にしっかりと保持する。追加のシースを必要としないが、最大の安定性を得るために追加のシースを使用してもよい。
本発明の別の部分は、配置される身体のキャビティの形状にできるだけ良好に適合させるためにその長さに沿って幾つかの外径を持つステントである。
本発明は、更に、スナップ作用2位置ユニットセルを持つ双安定バルブ及び特に失禁症をなくすためのその使用に関する。
本発明のステントの構造には、特別な方法で安定性を確保できるユニットセルからなる構成をもつ一連のエレメントが含まれる。各ユニットセルは、異なる機械的挙動を示す機械的に連結された全く異なる少なくとも二つの区分でできている。一方の区分は、他方の比較的可撓性の区分に対して比較的剛性の支持体として作用する。比較的可撓性の区分は、ステントの可撓性の全てではないにしろ大部分の原因である。この原理に基づいてステントを製造するには幾つかの方法があり、このステントは、ポリマー、組成物、従来の金属、又は超弾性挙動又は感温挙動を示す形状記憶合金等の様々な材料から製造できる。
回転させなければならない。第1c図は、ロッド1の中央部分をクランプすることによって、角度βに亘る回転に逆らい、この部分を軸線A−Aと平行に維持した場合に発生し、ロッドの2階湾曲(secondorder curvature)を示す。
ロッドを第1図の上安定位置2から下安定位置3まで移動させる。力は、ゼロからFmaxまで迅速に増大する。そのとき、第1b図及び第1c図の1階又は2階湾曲のいずれか
の開始に達する。X方向へのこれ以上の変位には力を殆ど必要としない。これは、このばねシステムが負のばね率を持つためである。力は中央部分でゼロとなり、これ以上の移動は自動的に生じる。システムが完全に対称であり、下位置から上位置に戻すのに必要な力は同じ特性を備えているということは第2図から理解されよう。
合には、反対方向への開始力はF2であり、F1よりも小さい。
ができるが、下位置の安定性が必要である場合には正の値を持つ必要がある。
第5a図及び第5b図は、本発明の管状ステントの外観を一杯に収縮させた形体及び一杯に拡張させた形体の夫々で示す。ステントは、全体に参照番号50を附したその一杯に収縮させた状態及び全体に参照番号60を附したその一杯に拡張させた状態において、複数の相互連結された双安定ユニットセル(第5b図において拡張状態で参照番号64が附してある)を有する。双安定ユニットセルは、比較的剛性の第1セグメント52(第5b図において参照番号66が附してある)及び比較的可撓性の第2セグメント54(第5b図において参照番号68が附してある)から形成されており、これらのセグメントは、端部70及び72のところで互いに接合されている。比較的可撓性の第2セグメント68は、隣接した比較的剛性の部材66に相互連結されている。長さ方向(長さ方向軸線には参照番号75が附してある)で隣接したセルは、端部70と72とが接合されている。半径方向外方又は内方に均等な力を加えることによって、ステントを一杯に収縮した形体から一杯に拡張させた形体まで直接切り換えることができ、又はその逆を行うことができる。
線方向での相対的変位に逆らう。これとは対照的に、セグメント8は、第1図で説明したロッド1又は第3図で説明したロッド5と同様の可撓性ロッドとして作用する。セグメント7及び8又は9及び10を組み合わせることにより、力−変位曲線F−Xが第2図及び第4図で説明した曲線と同様であり、非荷重状態及びセグメントの形状で決まる、双安定ばねシステムとして作用するユニットセルを構成する。変形例では、様々な直径のセグメント又はストラットを使用する代わりに、直径(即ち断面積)が同じであるが強度又は剛性が異なるセグメントでも同じ効果が得られる。このように強度又は剛性を異ならせるための一つの方法は、セグメントについて異なる材料を使用することである。別の方法は、全てのセグメントについて金属等の同じ材料を使用するが、剛性である必要があるセグメントを選択的に強化する(例えば熱処理によって)ことである。例えばニチノールは、熱処理を施すと更に柔軟になる。しかしながら、一方のニチノール製区分を熱処理が施してない第2のニチノール製区分に対して更に柔軟にするためにニチノールのこの性質を活用できる。
セグメント8は力FによってX方向に変形されているが、セグメント9はその剛性が大きいためにほぼその元の形状を有する。
び剛性区分)を持つように形成できる。
が第1直径であり、第2端部154が第2直径であり、第1端部152と第2端部154との間の領域156が一つ(又はそれ以上)の中間直径である。中間直径は、第1直径及び第2直径と異なる。第12図で全体に参照番号150を附したステントの相互連結されたセルは、全て、力定数(forceconstant)が同じであり、及び従って、必要な力を加えることによって全てのセルを一度に開放できる。又は、それ自体の力定数を各々有する幾つかの異なる種類のセルを含む。多数の直径を得るためには、大きさの異なるセルを使用するのがよい。この種のステントの一つの実施例では、第1及び第2の直径が同じであるが、別の実施例では第1及び第2の直径が異なる。
むのがよい。ステントの表面には、拡張リングに取り付けられたスキンが設けられている。スキンの取り付けでは、スキンが、拡張リング内で又は拡張リング間で取り囲むのがよい。スキンは人間又は動物の皮膚、ポリマー材料、又は任意の他の適当な生体親和性材料であるのがよい。
管404及び408の外側に載った随意のクランプ(例えば、下文において第23図にストリップの形体で示す、本発明によるコラプシブルステントの小さな部分)によりステントを脈管にクランプする。必要に応じて追加のクランプを使用できる。
トリガー手段620は圧電エレメントである。作動に当たっては、第19図に参照番号620で示す圧電エレメントが賦勢されていない場合には、バルブ閉鎖部材640は閉鎖している。圧電エレメント620を賦勢すると、圧電エレメント620の長さ方向長さ(第15図でYが附してある)が第20図に示すように僅かに短くなり、これにより可撓性部材608をその第1位置から解放する。部材608が解放されると、バルブ閉鎖部材640が自由になり、流体から伝達された圧力の作用で開放する。部材608は、第20図に示すように第2の逆の位置をとる。部材608は、流体圧力によってその第2位置に維持されるのであるけれども、流体が全くない場合でも、トリガーが消勢されて、圧電エレメント620がその元の長さになると、部材608は第20図に示すようにその第2位置にとどまる。流体が全くない場合、これに続いて圧電エレメント620を賦勢することにより、部材608をその第2(閉鎖)位置に移行できるようにすることによってバルブ閉鎖部材640を再び閉鎖できる。第2位置は、部材608にとって好ましい位置である。部材608は、第3図に示す好ましい位置を受け入れるように処理されている。
本発明は、上文中に説明した双安定ユニットセルに加え、他の形状の双安定ユニットセル及び更に一般的には多安定ユニットセルもまた企図している。第21a図及び第21b図は、本発明の別の実施例のヒンジ連結多安定セルをその収縮状態及び拡張状態で夫々概略に示す。全体に参照番号700を附した収縮状態のセル及び全体に参照番号705を附した拡張状態のセルは、相互連結された四つの比較的剛性の部材を含む。二つの側部材709は、ヒンジ715によって頂部材713の両端に連結されている。側部材709は、それらの反対端が底部材717の両端にヒンジ719によって連結されている。好ましくは、これらのヒンジは弾性変形可能であるか或いは塑性変形可能である。ヒンジは、側部材、頂部材、及び底部材に固定的に取り付けられているか或いはこれらの部材と一体であるのがよい。後者の場合には、セルのヒンジ領域から材料を除去してヒンジを薄くするか或いはヒンジの形状を側部材、頂部材、及び底部材と異ならせることによってヒンジを形成できる。拡張状態から畳まれた状態までの移行プロセスにおいて、底部材717は僅かに開放している。第21a図及び第21b図のセルは、二つの追加の中間状態を有し、この中間状態では、側部材709及び頂部材713の一方又は他方(しかし両方ではない)が下方に畳まれている。
及び第22b図に示す一杯に拡張させた状態及び一杯に収縮させた状態の他に、二つの中間安定形体をとることができる。これらの中間形体では、二つの上側部材762の一方だけが頂部材754に沿って畳まれている。
添付図面及び以上の説明には、様々な実施例のうちの幾つかの例が与えられているに過
ぎない。本発明のステントは、従来のステントと同様に見えるけれども、機械的にもたらされる結果が全く異なる。これは、同じユニットセルでの剛性区分と比較的可撓性の区分の特殊な組み合わせのためである。勿論、ユニットセルについて、図示の正弦波形状の他に、同様の特性挙動を持つ多くの他の可能な基本的形状がある。
