Description
繊維の所望の密度および固さや、濾過される塞栓の既知の大きさを実現してもよい。好適な実施例では、ワイヤメッシュは直径が0.002インチの少なくとも96のワイヤストランドで構成され、長さ方向の軸25に対して約35°の角をなすように配置される。好適なワイヤは、本分野で「エルジロイ(Elgiloy)」と呼ばれるコバルトの低熱膨張合金と、ニッケルの高熱高力の「超合金」(ニチノールを含む)、ニッケルの処理合金と、様々な等級のステンレス鋼と、ポリエステル、ナイロン、ポリテトラフルオロエチレン(PTFE)、ポリウレタン、ポリアリルエーテルエーテルケトン(PEEK)、ポリグリコール酸(PGA)、ポリラクチド(PLA)、ポリエプシロン−カプロラクトン、およびポリエチルアクリラート(PEA)を含むポリマとで構成されるグループから選択してもよい。また、プラチナおよびプラチナ合金も、メッシュ14に編組して、メッシュが卵円孔開存内に配置される位置を決定するのを補助できる。好適な実施例では、ワイヤストランドは、形状記憶合金、実質的に化学量論的なニッケルおよびチタニウムの合金であるNiTi(ニチノールとして知られている)から作られており、また、所望の特性を実現する少量の他の金属を含んでもよい。デバイス10のフレーム12と、ベース16、ベース18、右側アーム20、および左側アーム22を含むデバイスの構成部材は、いわゆる形状記憶合金から製造することが好適である。このような合金は、温度誘起相転移を有する傾向があり、これにより、素材が所望の形態になり、この形態は、素材を特定の転移温度以上に熱して素材の相転移を誘発することにより固定できる。合金が冷却された場合、合金は、熱処理中の形状を「思い出し」、その形状に強いて変更させることなく、その形状になる傾向がある。
