Description
工程1214において、予め形成されたバルーンはバルーンモールドから除去され、予め形成されたバルーンの外面は本明細書に記載されるPEG−ジメタクリレート等の架橋可能な親水化剤で処理される。処理に続いて、直接可視化カテーテルまたは代替の医療装置を構成するため、親水化されたバルーンについて他の製造工程に進んでもよい。
工程1240において、予め形成されたバルーンは必要に応じてバルーンモールドから除去され、工程1250において、複数のポリマーナノファイバーの少なくとも一部がバルーンの外面に沿って露出されるように、予め形成されたバルーンを反転する。いくつかの場合において、行程中に複数のポリマーナノファイバーの少なくとも一部が熱硬化性材料に入り込むことにより、繊維が非反転バルーンの外面に露出される場合には、工程1250は必要ない場合がある。
工程1340において、予め形成されたバルーンは、本明細書に記載される架橋可能な親水化剤、例えばPEG−ジメタクリレートで処理される。親水化されたバルーンは、熱硬化性材料が硬化された後のいつでも、マンドレルから除去することができる。親水化されたバルーンについて、直接可視化カテーテルまたは代替の医療装置を構成するため、後続の製造工程が行われてもよい。
