- 前記加熱アセンブリが、1または複数の追加の機能的要素として、前記カテーテルに流す電流を供給するための神経刺激アセンブリ、前記カテーテルに流す電流を生成するための1または複数のバッテリ装置、前記カテーテルの少なくとも一部を浸漬するための温度管理された水を貯留した水槽、および前記カテーテルの近傍で振動を生成するための超音波装置または振動装置のうちの少なくとも1つを含むことを特徴とする請求項2に記載のカテーテルアセンブリ。
- 前記コイルばねが、前記カテーテル本体部の壁部に埋め込まれていることを特徴とする請求項1に記載のカテーテルアセンブリ。
- 前記コイルばねが、前記カテーテル本体部の前記ルーメン内に嵌合されるサイズに形成されていることを特徴とする請求項1に記載のカテーテルアセンブリ。
- 前記形状記憶材料が、形状記憶ポリマーおよび形状記憶合金の少なくとも一方を含むことを特徴とする請求項1に記載のカテーテルアセンブリ。
- 前記形状記憶材料が、前記形状記憶ポリマーを含み、
前記形状記憶ポリマーが、ブロックコポリマー、熱可塑性ポリマー、熱硬化性ポリマーのうちの少なくとも1つを含むことを特徴とする請求項6に記載のカテーテルアセンブリ。 - 前記形状記憶材料が、前記形状記憶合金を含み、
前記形状記憶合金が、ニチノールを含むことを特徴とする請求項6に記載のカテーテルアセンブリ。
