Description
例1において、植込みリードをシールドする方法は、患者にリードを植込むステップを含む。リードは、先端側領域と、基端側領域と、先端側領域と基端側領域との間の中間領域と、先端側領域に配置された少なくとも1つの電極と、基端側領域から少なくとも1つの電極まで延びる少なくとも1つの伝導体と、を有する。方法は、中間領域の一部を巻き取り、1つ以上のループを画定するステップを更に含み得る。方法は、RFシールドによってリードの1つ以上のループを選択的にシールドするステップを更に含み得る。RFシールドは、金属材料を含み、1つ以上のループに沿った少なくとも1つの伝導体へのRF信号結合を低減するように構成されている。
例12は、RFシールドが、金属フィルム及び金属メッシュの少なくとも1つを含む、例10又は11のいずれかに記載のリード。
例14は、RFシールドが、リード上において摺動するように構成されたスリーブを含む、例10〜12のいずれかに記載のリード。
例16は、RFシールドが、リードの1つ以上のループのみをシールドする、例10〜15のいずれか1つに記載のリード。
例19は、リード本体を含む植込みリード。リード本体は1つ以上のループへと巻き取られるように構成されている。リードは、少なくとも1つの電極及びリード本体内に延びる少なくとも1つの伝導体を更に含みうる。少なくとも1つの伝導体は、少なくとも1つの電極にそれぞれ電気的に接続されている。リードは、RFシールドを更に含みうる。RFシールドはリード本体上において移動可能及びリード本体から取り外し可能であり、RFシールドは、1つ以上のループを取り囲み、1つ以上のループに沿った少なくとも1つの伝導体へのRF信号結合を低減するように構成されている。
複数の実施形態を開示するが、当業者には、本発明の例証的な実施形態を示し且つ記載する以下の詳細な説明から、本発明の更に他の実施形態が明らかになろう。したがって、図面及び詳細な説明は限定ではなく本質的に例示とみなされるべきである。
