Description
本出願は、2004年9月17日に出願された米国仮出願第60/611,191号の利益を主張し、この出願は、その全体が本明細書によって参考として援用される。
本明細書に記載される実施形態は、一般に、制限されずに、レーザー送達カテーテルへのレーザーエネルギーの送達のための改良された装置および方法に関する。
動脈は、心筋に血液および酸素を提供することを担当する主要な血管である。動脈疾患は、動脈がプラークの構築により狭められるか、またはブロックされるようになるとき生じる(いくつかの例として、アテローム硬化型プラークまたはその他の堆積物)。妨害物が重篤であるとき、心筋への血液および酸素の流れは、減少し、胸の痛みを生じる。ヒト身体中に形成される血餅による動脈妨害物は、多くの伝統的な方法で軽減され得る。硝酸塩、βブロッカー、および動脈を拡大する末梢血管拡張剤薬物または血餅を溶解するための血栓溶解性薬物を含む薬物療法は、有効であり得る。薬物処置が失敗した場合、血管形成術を用いて、動脈中のアテローム硬化型プラークまたはその他の堆積物を矯正または除去し得る。
いくつかの実施形態によれば、制限されることなく、本発明は、第1の近位端と第1の遠位端との間に中央軸を含む細長いハウジングを有するカテーテルを備える。このハウジングは、第1の近位端と、第1の遠位端との間に配置されたチャネルを有し、このチャネルは、第1の遠位端の近位方向に配置された腔と連通する。レーザー送達部材は、第2の近位端および第2の遠位端を有するチャネル内で移動可能であり、そしてその中に少なくとも部分的に配置される。ランプは、上記腔内で上記細長いハウジングの中央軸に対して角度をなし、その第1の遠位端の近位方向に配置される。このランプは、上記チャネルと連通し、そしてレーザー送達部材の第2の遠位端を上記細長い部材の中央軸から外方に移動するように適合される。ガイドワイヤは、上記レーザー送達部材および細長いハウジングの両方と機械的連通している。このガイドワイヤは、上記レーザー送達部材の第2の遠位端を、このハウジングの中央軸に向かってほぼ内方に付勢するように適合されている。いくかの実施形態では、制限なくして、ランプが、上記ハウジングの中央軸からの上記レーザー送達部材の先端部の中央軸のオフセットを決定するために用いられ、その一方、レーザー送達部材がランプ上を辿る範囲を調節することにより上記軸を実質的に平行に保ち、そしてこのレーザー送達部材のガイドワイヤ上の配置が、ハウジングの中央軸に実質的に平行にオフセット先端部を維持する。それらを用いる方法もまた開示される。
ここで、図面を参照して、例示の実施形態が詳細に示される。図面は、いくつかの実施形態を表すけれども、これら図面は、必ずしもスケール通りではなく、そして特定の特徴は、実施形態の革新的な局面をより良好に示し、そして説明するために誇張され得る。さらに、本明細書中に記載される実施形態は、網羅的であること、またはそうでなければ、本発明の実施形態を、図面に示され、そして以下の詳細な説明に開示される正確な形状および形態に制限または限定することは意図されない。
