Description
本開示は、外科的手技の間の使用のためのシステム及び方法に、より詳細には、眼の外科的手技の間の網膜下腔への治療薬の送達に関する。
一つの例示的な態様において、本開示は、網膜内の標的位置に治療薬を送達するための網膜治療装置を目的とする。網膜治療装置は、内腔を有し、かつ遠位端及び近位端を有する外管を含み、外管は、網膜外科手術を行うために眼を貫通するようにサイズ設定される。網膜治療装置は、外管の遠位端に付着された柔軟な先端をさらに含む。柔軟な先端は、網膜表面に対して接したときに網膜表面に柔軟に適合するように構成される。網膜治療装置はまた、外管の内腔内に配置された内管を含み、内管は、近位端及び遠位端を有する。内管の遠位端は、柔軟な先端内に伸び、内管は、柔軟な先端から伸びて、及び網膜の内側境界膜を貫通するように構成される。チャンバーは、内管の近位端に接続される。チャンバーは、内管が網膜の内側境界膜を貫通するときに、網膜の内側境界膜を越えて内管を介して治療薬注射剤を含む液体を受けるように構成される。
本開示の原則の知識を促進する目的で、ここで図面において図示した実施形態に対して参照がなされ、及び特定の言語がこれらを記述するために使用される。それにもかかわらず、本開示の範囲の限定は意図されないことが十分に理解されるだろう。本開示が関連する当業者に通常生じる得るとおり、本開示の原則の記述された装置、機器、方法及び任意のさらなる適用に対する任意の変更及びさらなる改変が完全に想定される。特に、一つの実施形態に関して記述された特徴、構成要素または工程を本開示のその他の実施形態に関して記述した特徴、構成要素及び/または工程と組み合わせてもよいことが、完全に想定される。単純さのために、いくつかの例において、同じまたは同様の部分に関して同じ引用番号が図面の全体にわたって使用される。
