Description
本明細書中及び上記の参照出願で引用したすべての文書及び参照文献は参照により本明細書中に援用される。
は、日常的な健康診断又は他の健康問題の診断手順の最中に発見される場合がある。破裂脳動脈瘤の診断は、一般に、くも膜下出血の徴候をCTスキャン(コンピュータ断層撮影法)で発見することにより行われる。CTスキャンが陰性ではあるものの破裂動脈瘤がなお疑われる場合、脳及び脊髄を取り囲む脳脊髄液(CSF)中の血液を検出するために、腰椎穿刺が実施される。
系の血行力学により、液体ポリマーは動脈瘤の嚢から逸脱する可能性がある。これもまた、親血管の不可逆的な閉塞につながる可能性がある。
メッシュキャリッジを有する。この新規な設計は、動脈瘤又は体腔内のより大きな血流阻止及び区画化を実現し、特により大きく且つより不規則な形状の動脈瘤を閉塞するための血行静止の増大をもたらす。
ジを含む連続的な圧縮可能なメッシュ構造体を含み、各キャリッジの各端部は、連続的なメッシュ構造体の挟持点である閉塞デバイスを体腔又は動脈瘤に送出することと、動脈瘤内に閉塞デバイスを留置し、それにより患者の動脈瘤を処置する又は改善することと、を含む。
は、メッシュの軸方向区分の端部に配置され、この端部を画定する。このような区分化されたメッシュキャリッジ20及び挟持点10は、多くの場合、連続的なメッシュ構造体又は網内にある。「挟持点」はメッシュ構造体の、拘束され、まとめられた位置として、離れた場所にある隣接するキャリッジの移動を制限するように機能し、それによってキャリッジを互いに安定させる。これらキャリッジ20の数(n)は臨床的及び実用的に可能な限り多く、大きな及び/又は不規則な大きさの動脈瘤90を処置するための、並びに約150センチメートル(cm)のカテーテル70(又はマイクロカテーテル)を通じて送出するための既知の診断技術に従い臨床医によって予め決定される。各キャリッジ20の長さ(x)30は、長さ(x)30が「遊離ガス」中においてキャリッジ20を寸法y(幅40)に拡張させるのに十分である限りは、所与の大きさの動脈瘤90を閉塞するのに適切と考えられるキャリッジ20の数(n)に応じて変えることができる。当技術分野で容認されている通り、このような閉塞デバイスの直径は遊離ガス中で測定される。各キャリッジ20の幅(y)40は、臨床的に実現可能であるためには、(遊離ガス中において)約2ミリメートル(mm)〜約50mmの範囲である。留置されると、キャリッジ20は、y40の寸法のキャリッジ20がy40の約2倍(又は2y)に増大することができるように、直径又は幅(y)40が約2倍まで増大する又は拡張するような状態で圧縮する。換言すると、各キャリッジ20はマシュマロのように圧縮して、x30の減少及びy40の拡大を生じさせる。一実施形態では、遊離ガス中において、各キャリッジ20はx30がy40より大きい又はy40に等しいような状態に設計され得るが、留置(圧縮)形状においては、y40はx30よりも大きい。一連の圧縮可能なキャリッジ20を含むこのような閉塞デバイスは、キャリッジ20の数(n)並びに各キャリッジ20の長さ(x)30及び幅(y)40を、処置される広範な大きさ及び形状の動脈瘤90又は体腔に適応するように選択するために、調節可能な状態で構成され得る。したがって、別の実施形態では、遊離ガス中において、各キャリッジ20はx30がy40以下であるような状態に設計することができ、留置(圧縮)形状においては、y40はx30よりも大きなままである。
ている。「マーカー」は周知であり、医療デバイス技術において容易に利用可能である。いくつかの実施形態では、マーカーは、金属材料、多くの場合、放射線不透過性材料からなり、閉塞デバイスの挟持点を囲み覆うためにバンド形マーカー、リング形マーカー、チューブ形等などの形状を取る。あるいは、マーカーは、所与の挟持点に巻回され、そのため、所与の挟持点を覆い囲んでいるワイヤストランドからなってもよい。一実施形態では、各挟持点10を囲み覆うマーカー50は、デバイスがカテーテル70(又はマイクロカテーテル)内のどこにあるか、及びデバイスが動脈瘤90又は体腔内に留置後どこにあるかに関し、X線下での位置的基準を提供する。図2は、連続的な圧縮可能なメッシュ構造体である一連の可変寸法の(寸法及び/又は直径が異なる)区分化軸方向メッシュキャリッジ20の例示的実施形態を示し、n=3の軸方向メッシュキャリッジ20であり、各キャリッジ20は、x30及びy40の寸法に関して異なり、各挟持点10はマーカー50によって囲み覆われている。図2に示すこのような構成では、動脈瘤90に入る第1のキャリッジ20(右側)は、処置される動脈瘤90の最大測定直径よりもわずかに大きな直径又は幅(y)40を有し、デバイスの連続的なメッシュ構造体が動脈瘤90の壁の最も薄く且つ最も敏感な領域であることが多い動脈瘤90のドームに接触しないようにする。加えて、図2に示すこの構成では、動脈瘤90に入る最後のキャリッジ20(左側)の直径又は幅(y)40は動脈瘤頚部100よりも大きく、この最後のキャリッジ20を動脈瘤90内部にしっかりと固定された(及び留められた)ままにする。
送出及び配置時におけるデバイスの位置の可視化を提供する。マーカー50は、各キャリッジ20、120の各端部にある挟持点10を覆い囲むように閉塞デバイス上に配置されている。このように、近位キャリッジ20、120の近位端にあるマーカー50は、動脈瘤90の頚部100の上方又は内部に載置することが可能である。マーカー50の中実性によって、動脈瘤90内におけるデバイスの安定性を付与し、圧縮可能なメッシュキャリッジ20、120を介した力の移動又は伝達を防止することで、デバイスの誤配置又は偶発的な移動を防ぐ。マーカー50はまた、送出カテーテル70又はガイドワイヤ60及び/若しくはプッシャワイヤ技術などであるが、これらに限定されない対応する送出手段と連係し、送出手段から解放する/送出手段に取り付けるための接合部を備えて構成されている。マーカー50はまた、有利には、本明細書中に開示されるデバイスの完全回収可能性を提供する。

トランドはポリマーコーティング又は押出品で被覆されてもよい。放射線不透過性ワイヤストランドを覆うコーティング又は押出品はX線透視可視化を提供するが、曲げ疲労に対するストランドの抵抗も増加させるとともに、ストランドの潤滑性も高めてよい。一実施形態では、ポリマーコーティング又は押出品は、コーティングされている又はへパリンなど抗凝固の傾向がある薬剤で処理されている。このような抗凝塊コーティングは全般に知られている。ポリマーコーティング又は押出品は、任意の適切な押出可能なポリマー、又はTeflon(登録商標)若しくはポリウレタンなどの薄いコーティングで適用することができる任意のポリマーであり得る。
シュ密度を有する。本明細書中に開示される閉塞デバイスの目的において、用語「メッシュ密度」は、有孔率のレベル又はメッシュ構造体の開口面積に対する金属の比率を意味する。メッシュ密度は、メッシュの開口又は孔の数及び大きさ、並びに開口又は孔の開口状態が送出と留置との間で変化する状況において孔が開放又は閉鎖している程度に関係する。概して、弾性メッシュ材料の高メッシュ密度領域は概ね約40%以上の金属面積及び約60%以下の開口面積を有する。
and Use Committee(IACUC)によって検討及び承認され、手順は獣医の監督下で実施した。
Testing Endovascular Devices.AJR 2000;174:349−354を参照のこと。)したがって、このモデルは適切な試験モデルとして規制機関により即座に承認される。このモデルの凝固系はヒトの凝固系と酷似している。加えて、このモデルは、ウサギの頭蓋外頚動脈の直径がヒトの頭蓋外頚動脈の直径と酷似しているという点で有利な解剖学的側面を有する。更に、エラスターゼ誘起動脈瘤はヒトの動脈瘤と組織学的に類似するように挙動することが示されている。
