Description
様々な実施態様の詳細な説明では、本明細書中で添付図面に触れるが、その図面は、制限ではなく、例示と最良の態様によって様々な実施態様とその実施を示している。これらの実施態様は当業者がその実施態様を実施できるくらい十分詳細に記載されているが、他の実施態様が実現され得ること、並びに機械的及び他の変更が本開示の要旨及び範囲から逸脱することなく行われ得ることは、理解されなければならない。さらに、単独の実施態様に対するあらゆる言及は複数の実施態様に対する言及を包含し、さらに2以上の部品に対するあらゆる言及が単独の実施態様に対する言及を包含することもある。そのうえ、述べた特徴を有する複数の実施態様の列挙は、付加的な機能を有する他の実施態様又は述べた特徴の異なった組み合わせを組み込んだ他の実施態様の排除を意図するものではない。
直径0.35mmのステンレス製ワイヤーを入手した。このワイヤーを、ePTFEフィルムから細長く切ったテープの全長がバイアスプライ(bias-ply)な螺旋状の形でそれに巻き付けられるマンドレルの代わりとし、該フィルムはBacinoに対するUS 5,476,589に記載のとおり作製した。前記テープを作り出すために、薄いePTFEフィルムを約3mm幅に細長く切り、そして層が約0.1mmの壁厚を確立するまで、最小限の張力でワイヤーマンドレル上に螺旋状に巻き付けた。長さ約15cmの部分をこのように作製し、次いで、サーモスタットにより370℃で作動するように設定したGrieves Model1100空気対流オーブン内で10分間、熱処置にかけた。
