Abstract
【解決手段】カテーテル10は、アセンブリ18の遠位端部又は近位端部のいずれかから圧縮力がかかったとき、所定の予測可能な様式において超屈曲するように構成されたスパイン27を有するバスケット形状の電極アセンブリを備える。少なくとも1つのスパインは、その遠位及び近位領域を含むスパインの残りの領域の構造及び硬さを損なうことなく、さもなければ、アセンブリと接触した組織壁への損傷又は傷害をもたらし得る過剰な力を吸収及び減衰するため、電極アセンブリが変形、例えば、圧縮することを可能にする、より高い(又は超)可撓性の少なくとも1つの領域を有する。スパインのより高い可撓性の1つ又は2つ以上の領域は、スパインが概ねV形状の構成又は概ねU形状の構成に屈曲することを可能にする。
