Description
1−1.生分解性高分子のコーティング
ポリ乳酸−グリコル酸共重合体(PLGA;ベーリンガーインゲルハイム社、インゲルハイム、ドイツ)(生分解性高分子1)を、メチレンクロライド(CH2Cl2)に10重量%になるように溶解した。この後、レーザー加工したステント本体(テウンメデカル社、韓国)の表面に通常のスプレー法を用いて、厚さが10μmになるように生分解性高分子をコーティングした。
前記1−1において得た、PLGAポリマーがコーティングされたステントの表面に、周波数(Radio Frequency)が13.56MHzのPACVD法を利用してArプラズマを処理した。具体的には、PLGAポリマーの表面にチャンバー圧力が1.33Paで、電圧が―800Vの条件で5分間Arプラズマ処理をした。これによりしわ状のナノ構造を形成した。この際、処理時間及びチェンバー内の圧力によってナノ構造は多少変化することもある。
PLGA(ベーリンガーインゲルハイム社、ドイツ)(生分解性高分子2)を、メチレンクロライドに3重量%となるように溶解した後、PLGAの1/10の量の、パクリタキセル(paclitaxel; アルドリッチ社、50mg)(薬物2)を添加して混合した。混合溶液を前記1−1と同様のスプレー法によって、前記1−2において得たナノ構造パターンが形成された生分解性高分子の表面に、厚さが2μmになるようにコーティングした。
実施例1−3の段階で、生分解性高分子を10μmの厚さにコーティングすることを除いては、実施例1と同様の方法によって、ナノ構造パターンが形成された生分解性高分子の表面にコーティングを行った。
実施例1−1における生分解性高分子のコーティング段階において、PLGA(ベーリンガーインゲルハイム社、インゲルハイム、ドイツ)(生分解性高分子1)を、トルエンに10重量%となるように溶解した後、これにパクリタキセル(アルドリッチ社、50mg)(薬物1)を添加していることを除いては、実施例1と同様の方法によって、ナノ構造パターンが形成された生分解性高分子の表面にコーティングを行った。
実施例1において得たステントの表面を分析するために、原子間力顕微鏡(AFM)(オートプロブCPリサーチシステム、サーモマイクロスコープ社、米国)を用いて、非接触モードで2μm角の領域の表面粗度を測定した。表面粗度は、二乗平均粗さ(Root Mean Square; RMS)を用いた。また、表面の形状を走査電子顕微鏡(nano-SEM、FEI社、米国)によって撮影して、その結果を図2a及び図2bに示している。図2aは、NiTiステントの表面の光学顕微鏡の写真であり、図2bは、ステントの断面とその表面の走査電子顕微鏡の写真で、ナノ構造が形成されていることが確認できた。表面のナノパターンの幅は約200nmで、高さは100nmであり、表面のナノパターンは、様々な条件によってその幅と高さを変えることができる。
