Description
この出願は、2014年9月4日に出願された「経頸動脈(transcarotid)アクセスのための方法およびデバイス」と表題が付けられた米国仮出願番号62/046,112号および2014年11月4日に出願された「経頸動脈アクセスのための方法およびデバイス」と表題が付けられた米国仮出願番号62/075,169号の優先権の利益を主張する、「経頸動脈アクセスのための方法およびデバイス」と表題が付けられ2014年11月10日に出願された米国特許出願番号14/537,316号の継続出願である、「経頸動脈アクセスのための方法およびデバイス」と表題が付けられ2014年12月18日に出願された米国特許出願番号14/575,199号の優先権を主張する。前述の出願日の優先権を主張し、それらの特許出願の全体が、参照によって本明細書に取り込まれる。
いくつかの例では、所望のアクセス部位は、頸動脈である。例えば、頸動脈分岐部および内頸動脈の疾患を処置するための手技は、このアクセス部位にかなり近い。頭蓋内および脳の動脈における手技は、同様に、大腿動脈よりもこのアクセス部位に、はるかに近い(closure)。この動脈も、上に示した代替のアクセス動脈のいくつかよりも大きい。(総頸動脈は、典型的に、直径が6〜10mmであり、橈骨動脈は、直径が2〜3mmである。)
図2を再び参照すると、経頸動脈用動脈アクセスシース220の1つの実施形態は、細長いシース本体222と、アクセスシース220の細長いシース本体222の近位端にある近位アダプタ224とを含む。細長いシース本体222は動脈アクセスシース220の一部分であり、動脈の中に挿入されるように寸法が決められて成形されており、細長いシース本体の少なくとも一部分は、手技中に動脈の中に実際に挿入される近位アダプタ224は、止血弁226と、シース本体222の内部管腔と連通する内部管腔を有する細長い噴出ライン228とを含む。近位アダプタ224は、シース本体222よりも大きい直径または断面の寸法を有していてもよい。止血弁226はシース本体222の内部管腔と連通しており、手技中に、内部管腔を介した血液損失を回避または最小限にしつつ、その中にデバイスを導入することを可能にしている。1つの実施形態では、止血弁226は、静的シール(static seal)タイプパッシブ弁である。(図5に示された)動脈アクセスシース220の代替の実施形態では、止血弁226は、ツイボースト(Tuohy−Borst)弁227または回転止血弁(RHV)などの調整可能な開口弁である。代わりに、アクセスシース220は、パッシブシール弁、ツイボースト(Tuohy−Borst)弁、または回転止血弁(RHV)のいずれかの独立した止血弁の構成要素を取り付けることができる、メスのルア(Luer)アダプタの近位端で終端してもよい。
脈、または大動脈弓、大動脈弁、冠動脈、または他の末梢動脈であってもよい。これらのターゲット位置に対して、細長いシース本体222の適切な長さは、ターゲット位置からアクセス部位までの距離に依存する。この構成では、細長いシース本体222は、動脈アクセス部位を通して置かれ、大動脈に向かって下方に方向付けられる。
図2を再び参照すると、シース拡張器260は、経頸動脈アクセスシースシステム200の構成要素である。シース拡張器260は、動脈の中に挿入される細長い本体であり、動脈壁の穿刺部位を通して、シースガイドワイヤ300の上へのアクセスシース220の滑らかな挿入を可能にする。したがって、拡張器260の遠位端は、拡張器を動脈中のシースガイドワイヤ300上に挿入することができるように、そしてニードル穿刺部位を、アクセスシース220そのものの挿入のために大きい直径に拡張させるために、一般に、テーパ状である。これらの機能に適合するために、拡張器260は、(拡張器の長手方向軸線に対する)全体的な角度(または全体を含む角度:total included angle)が概ね6〜12度のテーパを有し、丸い先端(leading edge)を備えたテーパ端部268を有する。シース拡張器は、動脈の中への挿入のために組み立てられたとき、典型的に、アクセスシースに固定される。例えば、シース拡張器260の近位ハブ264は、動脈アクセスシース220の止血弁226の対応する構造の中または上方に嵌めこまれるように構成されている。拡張器260の内部管腔は、例えば、シースガイドワイヤサイズに応じて、0.037〜0.041”の内側直径を有するシースガイドワイヤ300に適合する。
動脈アクセスシースは、典型的に、0.035”または0.038”直径のシースガイドワイヤ上で、動脈中に導入される。拡張器の遠位先端の内側直径およびテーパ長さは、このようなガイドワイヤと一致するように寸法が決められる。例えば、橈骨動脈アクセスのためのいくつかのシースは、遠位先端の内側直径およびテーパ長さを有する対応する拡張器とともに、0.018”直径のシースガイドワイヤに適合するように寸法が決められる。シースガイドワイヤは、傷つけない直線状の、角度が付いた、またはJ先端を有していてもよい。ガイドワイヤは、近位端の固いセグメントに滑らかに移行する。この構造は、シースが動脈中のワイヤ上に導入されたときにシースのための支持を可能にしつつ、動脈の中へのワイヤの傷つけない侵入および前進を可能にする。典型的には、傷つけない先端からの移行は、固い部分に対して、約4〜9cmである。シースが挿入されたときに、ワイヤの固いセグメントが動脈の侵入部位に存在するように、シースは、通常、動脈の中に15〜20cm挿入される。
図1を参照すると、初期経頸動脈アクセスのためのマイクロアクセスキット100は、アクセスニードル120、アクセスガイドワイヤ140、およびマイクロアクセスカニューレ160を含む。マイクロアクセスカニューレ160は、本体162と、本体162の管腔の内部でスライド可能に配置された内側拡張器168とを含む。典型的には、動脈アクセスのために、改良されたセルジンガー技術が使用される場合、初期ニードル穿刺は、21Gまたは22Gアクセスニードル、または18Gニードルにより行われてもよい。経頸動脈アクセスでは、さらに小さいニードル穿刺によってアクセスすることが望ましい。頸動脈の経皮的アクセスは、典型的に、大腿動脈のものよりも困難である。頸動脈は、厚い壁の動脈であり、頸動脈シースとして知られた組織スリーブに囲まれており、それは、筋肉組織を取り囲むのと同様に固定されておらず、それゆえに、初期ニードル刺し(initial needle stick)は難しく、不安定な動脈に、より大きな力で刺さなければならず、したがって、誤った部位への穿刺、動脈の切断、または後壁穿刺のリスクが増加する。小さい初期ニードル穿刺、例えば、23Gまたは24Gニードルは、ニードル侵入の容易性を増加させ、これらのリスクを減少させる。シースガイドワイヤは、小さいニードル、例えば、0.016”または0.014”ワイヤに適合するように適切に寸法が決められるべきである。アクセスニードル120は、超音波ガイドによる動脈中へのニードル挿入を支援するために、超音波でそれを見ることができる状態にするように、遠位端にテクスチャー加工した表面を含んでもよい。ニードル長さは、長さ4cm〜8cmの範囲にあってもよい。
上で説明されたデバイスのいずれかまたは全ては、システムの1つ以上の構成要素が一般的なパッケージまたはパッケージの集合に含まれるように、ユーザにキットの形で提供されてもよい。アクセスシースキットの1つの実施形態は、上で説明されたような経頸動脈アクセスのために構成されたアクセスシース、シース拡張器、およびシースガイドワイヤの全てを備える。
ここに、経頸動脈アクセスシステムのための例示の使用方法を記載する。頸動脈狭窄を処置するための例示の経頸動脈手技では、ユーザが、総頸動脈に至るまで切断を実行することによって開始する。その後、ユーザは、所望のアクセス部位でアクセスニードル120を総頸動脈の中に挿入する。経頸動脈アクセスのために構成されたテーパを有するアクセスガイドワイヤ140は、ニードルを通して総頸動脈の中に挿入され、CCAの中に前進される。アクセスニードル120は抜去され、マイクロアクセスカニューレ160は、CCA中のワイヤ140上に挿入される。マイクロアクセスカニューレは、ガイドとして、カニューレのマーク166を使用して所望の深さに挿入され、過挿入を回避する。
