Description
直径が約0.23mmで長さ約1メートルの10%白金の延伸−充填ニチノールワイヤ(Fort Wayne Metals,For Wayne,IN)を入手する。ワイヤの具体的長さは測定されてもされなくてもよいが、ワイヤは以下の段落で説明するような巻回パターンを完成させるのに充分な長さを有していなければならない。電解研磨したワイヤを得る。ニチノールワイヤを電解研磨することで、表面上に二酸化チタン層を自発的に形成する特性、ワイヤの表面上のニッケル量を選択的に削減する特性、及びワイヤ内の一部の応力を取り除いて疲労を改善させる特性などの、いくつかの周知の特性が付与される。
メタノール泡立ち点:4.8kPa(0.7psi)
単位面積質量:2.43グラム/平方メートル
長手方向マトリクス引張り強度:662MPa(96000psi)
長手方向最大荷重:0.6kg/cm(1.6kg/インチ)
厚み:0.00889mm
マトリクス引張り強度=(σsample)*(ρPTFE)/(ρsample)
式中:ρPTFE=2.2グラム/cc
σsample=(最大荷重/幅)/厚み
ρsample=(単位面積質量)/厚み
密度は、密度=質量/体積という式を用いて計算する。
単位面積質量:36.1グラム/平方メートル
長手方向最大荷重:4.96kg/cm(12.6kg/インチ)
横断方向最大荷重:0.12kg/cm(0.3kg/インチ)
厚み:0.03mm(0.0012インチ)
密度:0.531g/cc、
長手方向のマトリクス引張り強度:34215MPa、
厚み:0.086mm。
以下の点を除いて、実施例1と同じ要領で、同じ材料を使用して、物品を製造する。すなわち、フィルム管は管として適用せず、むしろこれを長手方向に細長く切り、結果として得た平坦なシートを用いてニチノールフレームを被覆する。閉塞性部材に張力を加えることなく、シートを上部フレームペタル全体にわたり垂らしてかけ、シートの縁部にひだを付け、中心アイレットのまわりに固定する。結果として得た物品の閉塞性構成要素は、図9に示されている通りの平坦な近位表面とカップ状の遠位表面を伴うカップ状閉塞性構成要素を有する。
以下の点を除いて、実施例1と同じ要領で、同じ材料を使用して、物品を製造する。カップ状閉塞性部材とアンカー構成要素を、手で中心アイレットを挟むことによって互いに切り離す。図19A〜19Bに示されているアイレットの外径のものと類似の直径を有するePTFE管を入手し、カップ状閉塞性部材の遠位アイレット及びアンカー構成要素の近位アイレットにしっかり固定する。管は、前述の通りFEPを含むテープを上に巻き付けることによってしっかり固定する。
以下の点を除いて、実施例1と同じ要領で、同じ材料を使用して、物品を製造する。カップ状閉塞性部材とアンカー構成要素を、手で中心アイレットを挟むことによって互いに切り離す。図19A〜19Bに示されているアイレットの外径と類似の直径を有するePTFE管を入手し、カップ状閉塞性部材の遠位アイレット及びアンカー構成要素の近位アイレットにしっかり固定する。結果として得られたアイレットの外径にLoctite4011接着剤を塗布し、アイレット全体にわたりPTFE管を硬化するまで固定することによって、管をしっかり固定する。
以下の点を除いて、実施例1と同じ要領で、同じ材料を使用して、物品を製造する。カップ状閉塞性部材とアンカー構成要素を、手で中心アイレットを挟むことによって互いに切り離す。外径と類似の直径を有するePTFE管を前述の通りにePTFEフィルムから形成した。カップ状閉塞性部材の遠位アイレットとアンカー構成要素の近位アイレットに管をしっかり固定する。その後、アセンブリを320℃で3分間加熱して、管を収縮させ、それをアイレットにしっかりと固定する。
