Description
現代医療では、閉塞、疾病または損傷を蒙った動脈セグメントにバイパスを形成するのが望ましいことがよくある。血管の閉塞、疾病または損傷セグメントのバイパス形成に用いられる典型的な外科手法は、動脈の開存性外科的露呈と、移植片の一端が閉塞、疾病または損傷セグメントの上流に接続され、移植片の他端がその下流で動脈に接続されるような、罹患動脈への管状移植片(例えば同種移植片、異種移植片、同種異系移植片、プロテーゼまたはバイオプロテーゼ移植片)のアタッチメント(例えば縫合糸)を必要とする。このようにして、動脈血はバイパス移植片を通って運ばれ、それにより動脈の閉塞、疾患または損傷セグメントに対して遠位の血流を元に戻し、罹患動脈を通る血流障害に起因する組織虚血、梗塞およびその他の後遺症を防止する。
冠状動脈疾患は依然として世界中で罹患率および死亡率の主な原因の1つである。冠状動脈疾患の典型的病因は、冠状動脈内のアテローム硬化性斑の増大を特徴とする。アテローム硬化性斑のこのような沈着は罹患冠状動脈を通る血液の流れを完全にまたは部分的に遮断しがちで、処置されない場合には心筋虚血、梗塞および死を引き起こすおそれがある。
末梢血管性疾患は、普通は末梢動脈内のアテローム硬化性斑および/または血栓物質の蓄積に起因する。多くの場合、末梢血管性疾患により下肢の動脈が閉塞されると、間欠性跋行として公知の現象が生じる。間欠性跋行は尽力(即ち歩行または走行)中の足の疼痛および進行性衰弱の発生を特徴とする。
体内の種々の動脈は、外傷(例えば裂傷、挫傷、鈍性腹部外傷)により損傷されるか、または血管外疾患経過(例えば隣接腫瘍の増殖および内方成長)により侵襲または圧迫されるようになることがある。このような外傷または疾患により影響を受ける動脈の治療のための典型的な外科的アプローチは、動脈の罹患セグメントを外科的に露呈して直示し、その後、a)切除および再接続するか、あるいはb)動脈の罹患セグメントにバイパス形成して動脈の罹患セグメントを通るまたはその周囲の血流を元に戻す方法である。多くのこのような場合には、損傷または疾患による影響を受けた動脈のセグメントが大きすぎて、罹患セグメントを簡単に切除、除去したり、動脈の隣接切断端の端と端を吻合することができないことがある。したがって、切除および端と端の吻合が任意にできないような場合には、罹患動脈に管状バイパス移植片(例えばポリエステル織物またはePTFEで形成される管状移植片)を取り付けて、この動脈の罹患セグメントにバイパス形成するのが望ましい。
多くの種類の外科的および介入的手法が、これまで器官、組織または体腔に形成されてきた。伝統的には、このような器官、組織または体腔へのアクセスは、身体に1つまたはそれ以上の開存性外科的切開を形成し、それにより罹患器官、組織または体腔が外科的に露呈されることにより達成される。

i.血管再生法
概して、本発明の血管再生法は、血液が少なくとも1つの血管からまたは血管中に流れ得る1つまたはそれ以上の経路10を確立するための方法を提供する。ほとんどの場合、経路を通って流れる血液は、好ましくは約50の余分量のpO2を有する。
上記の血管再生法の他に、本発明はさらに体内の血管外位置での種々の外科的または介入的手法の実施方法を含む。本発明のこれらの方法は、血管から血管外位置(例えば器官、組織、体腔等)への1つまたはそれ以上の血管外経路を形成し、その後1つまたはそれ以上の手法実施装置を血管外経路に通して血管外位置での所望の外科的または介入的手法を成し遂げることにより達成される。本発明のこの方法により実施される外科的または介入的手法の型を以下に示す:
・ 流動性薬剤物質の送達;
・ 埋込可能な薬剤送達装置(例えばミクロスフェア)の埋込み;
・医療液の送達;

図2cを参照すると、皮下入口装置105はアクセスカニューレ103の近位端に取り付けられて、アクセスカニューレ103を通って標的領域Tへの、流動性物質(例えば薬剤、医療液、X線写真用造影剤、細胞、遺伝物質、微生物またはウイルスベクター等)の注入または撤退に用いられる。さらに、入口装置105およびカニューレ103は、標的領域Tでの圧力またはその他の条件の定期的モニタリングを行う(例えば、カニューレ103に液体を充填し、圧力変換器に連結した針を入口装置105に挿入して、標的領域Tでの圧力を読み取る)。したがって、図2cは、皮下に位置する注入口105を有する内在性アクセスカニューレ103が標的領域Tへの/から流動性物質の注入または撤退を継続するために用いられる方法を説明する。体内の特定の標的領域Tへの薬剤の反復注入により処置される症状の特定の例としては、パーキンソン病、てんかん、高血圧、腫瘍、うつ病、アルツハイマー病、睡眠障害、行動障害、運動機能障害等が挙げられる。さらに、アクセスカニューレ103および注入口105は、種々の種類の置換療法を実施するために、置換液または溶液を定期的に注入するための手段として用いられる。これらの適用はさらに、図2dに示されている用具を用いて実施される。
図3a〜3g、および下記の詳細な説明は、本発明に従って形成される血管外経路10のある種の型を記載する。図3a〜3g、および以下の詳細な説明は、形成され得る経路の型の単なる例を示すものであって、本発明に従って用いられる経路10の考え得るすべてを余すところなく記載するものではない。さらに、図3a〜3gは静脈と動脈の間に形成される経路10を示してはいるが、図3a〜3gに示されている種々の経路の変形は、このような変形が適している本発明に従って形成される血管外経路10のいずれかまたはすべての型に広く適用可能である。実際、図3a〜3gに示されている、そして以下に記載した経路10は、動脈と静脈の間に形成される経路に限定されず、本発明のすべての経路10に広範に適用可能である。
図4a〜4e、ならびに以下の詳細な説明は、本発明のある種の血管再生法を実施するために2つの血管の間に血管外経路10を形成するのに用いられるいくつかのアプローチを説明するために提示される。図4a〜4e、ならびに以下の詳細な説明は、このような経路10を形成するために用いられるアプローチの考え得るすべてを余すところなく示すものではなく、むしろこのような手法に関して目下了解されているアプローチの単なる例として提供される。さらに、図4a〜4eは、閉塞OBが血管の1つの内側に存在する適用を示すが、これらの図面で説明される一般的アプローチは、経路10が閉塞を迂回する以外の目的のために形成されるか、あるいは閉塞OBが経路10が形成される位置から遠く離れて位置する種々の血管再生方法に適用可能である。さらに、図4a〜4cに示されるアプローチは、必ずしも2つの血管の間で、あるいは動脈と静脈の間で実施される必要はない。実際、これらのアプローチは任意の血管と任意のその他の中空性解剖学的構造との間に適用可能であり、静脈−静脈、動脈−動脈または静脈−動脈経路10に用い得る。
図5a〜5rは、所望の血管外経路10を作るために、本発明のカテーテル100から進められる場合に、組織貫通素子102を配向し、照準を合わせ、制御し、および/または案内するために用いられる装置の例を示す。概して、これらの配向、照準合わせ、制御および案内装置は、組織貫通素子102がカテーテル100から通り抜ける場合にカテーテル100が位置する血管の壁と接触し、貫通するように、カテーテル100を配備するよう意図される。図5a〜5rに示されている図、ならびに以下の詳細な説明は、本発明に用いられる配向、照準、制御および/または案内装置の型の単なる例として提示されるものであり、これらの目的のために用いられる装置の考えられるすべてを網羅して示すかまたは説明するものではない、と理解すべきである。さらに、図5a〜5rに示されている、下記に説明する装置のいずれかまたはすべてが、本発明の経路形成カテーテル100が配向、照準、制御または案内される「システム」を形成するために本明細書中に記載されている本発明のあらゆるその他の素子と組合せられる、と理解すべきである。
図6〜12は、本発明に従って血管外経路10を形成し、そうでなければこのような経路10を変形するかまたは装備するために用いられる本発明の用具を示す。図6〜12の図面および下記の詳細な説明は用具のある種の例および目下好ましい実施態様を記載し、説明するだけのものであって、本発明が物理的形態をとり得る用具または実施態様の考え得るすべてを網羅的に記載し、説明するものではない、と理解されるべきである。
図6a〜6jは、所望の血管外経路10を作るために、組織貫通素子102がカテーテル100が配備される血管の壁を通り抜けるように、本発明の血管外経路10を最初に形成するために使用される組織貫通素子102が、血管の管腔内に置かれた経路形成カテーテル100から抜き出される配置および装置の例を示す。
図6fは、カテーテル用具100eが格納式外部カテーテル鞘190、およびその遠位部分に形成されるかまたは取り付けられるプレベント弾性管194を有する延長内部部材192を包含するカテーテル用具100eの別の実施態様を示す。図に示されているように、外部カテーテル鞘190が近位方向に引っ込められた場合に、プレベント弾性管状部材194が外方に、そのプレベント側方弯曲形状に飛び出すように、延長内部部材192は鈍遠位先端196およびその中に形成される延長外側開口198を有する。この実施態様の組織貫通素子102は 柔軟性部材であるか、または内部管部材194の遠位端に形成される遠位端開口114eから出される場合に、プレベント形状をとるプレベント弾性部材である。このようにして、プレベント管部材194は、カテーテル鞘190が近位方向に引っ込められた場合は一次角A1を形成し、プレベント管部材194の遠位端開口114eから出される場合には、さらに二次角度A2を形成し、したがって一次角度A1および二次角度A2は併合して組織貫通素子102の遠位先端が照準を合わせる方向とカテーテル100eの縦軸LAとの間に第三の角A3を形成する。上記で詳細に説明したように、組織貫通素子102の遠位端の方向とカテーテル100eの縦軸LAとの間の角度A3は、必ずしも経路10が組織貫通素子102により形成される正確な角度を示したり、限定するものではない。実際、組織貫通素子102は、連続曲線経路を作る連続曲線形状を含むあらゆる適切な形状を有する。
以下の図7a〜7rならびに添付の下記の詳細な説明は、本発明に従って用いられる組織貫通素子102のいくつかの型を記載し、説明するためのものである。下記に記載し、図7a〜7rに示されている組織貫通素子の特定の型は、使用可能な組織貫通素子102の型の考え得るすべてを網羅的に記載し、説明するものではなく、むしろ使用され得る組織貫通素子102の型の例を提供するためのものである、と考えられ、理解されるべきである。上記のように、「組織貫通素子」という用語は、固体部材に限定されるものではなく、種々の用具、装置またはエネルギー流も含まれる。さらに、「弾性プレベント部材」という用語は、上記のような用語の定義に従って解釈される。
図8a〜8h、ならびに下記の詳細なその説明は、組織貫通素子102により最初に形成される血管外経路10を処置し、拡大し、嵩下げし、膨張し、内張りし、被覆し、そうでなければ変形するために用いられる種々の型のアプローチを示す。図8a〜8hの図面および下記の詳細な説明は本発明に従って用いられる経路変更装置の型の代表例を説明し、示すものであって、本発明により使用可能な経路変形装置の考え得る型の各々およびすべてを網羅的に記載し、説明するものではないと考えられ、理解されるべきである。
本発明の血管外経路10が2つの血管の間に形成される適用(多数の上記の血管再生法の場合のような)では、血管の壁の間の海綿状または疎性組織の存在が問題であり、この場合、経路10を流れる血液がこのような海綿状または疎性組織中に浸潤し、それにより血液漏出および/または血腫形成が生じる傾向がある。
図10a〜11dは、好ましい経路形成カテーテルと、本発明に従って、経路形成システムを形成するために組合せる付随装置についての2つの基本的実施態様を示す。図12a〜13bは、図10a〜11dに示されている経路形成カテーテルおよびシステムを用いて2つの隣接血管BV1、BV2間に血管外経路10を作るための好ましい方法を段階的に提供する。
図12a〜12dは、図10〜10eに示されている組織貫通カテーテル用具およびシステム100pの第一の実施態様を用いる好ましい方法の段階的な図を示す。
図13a〜13bは、好ましい経路形成カテーテル用具およびシステム100p′の第二の実施態様を用いる好ましい方法の段階的な図を提示する。
最初に、イメージングカテーテル50および経路形成カテーテル用具100p′が、組合わされて、経路形成「システム」となるように、所望のイメージングカテーテル50がサイドカー720の管腔722に挿入される。
その後、図13dに示されているように、経路形成カテーテル用具100p′および付随のイメージングカテーテル50が引き出され、体内から取り出されて、それにより一次血管BV1の管腔を通り、経路10を通って、二次血管BV2中に延びるガイドワイヤGWが残される。
ある種の特定の実施態様および実施例のみを参照しながら本発明を上記で説明した、と理解されるであろう。したがって、本明細書は、本発明の実施態様の考え得るすべてを網羅的に記載したものでも、あるいは本発明が実施され得る各々のおよびすべての方法の例を提供するものでもない。実際、本発明の意図された精神および範囲を逸脱しない限りにおいて、上記の実施態様および実施例に対して種々の付加、削除、修正および変更がなされ得ることは、当業者には明らかであろう。したがって、このような付加、削除、修正および変更は、以下の請求の範囲に含まれるものとする。
