Claims (9)
- 子宮ポリープを切除するための組織切除デバイスであって、
長手方向軸線を有する細長い構造体を有し、前記細長い構造体は、子宮ポリープ組織を受入れるように構成された遠位窓を含む外側スリーブと、前記遠位窓に対する近位位置と遠位位置の間を移動するように構成された内側スリーブを含み、
更に、第1の極性を有する電極要素を有し、前記電極要素は、前記内側スリーブに結合され、前記遠位窓を横切るように近位位置と遠位位置の間を移動可能であり、
前記外側スリーブは、第1の極性と反対の第2の極性を有する戻り電極として機能し、
更に、前記電極要素の近位側の前記内側スリーブを覆う絶縁層を有し、前記絶縁層の一部分は、遠位位置において前記遠位窓の中で露出され、
前記絶縁層は、前記内側スリーブの遠位端部を遠位側に越えるように延び、前記電極要素の少なくとも一部分を覆って、前記電極要素に直接に結合され、
前記絶縁層は、耐摩耗性の低い材料で構成され、その結果、前記絶縁層は、前記内側スリーブから摩耗し、前記内側スリーブの一部分を露出させ、前記電極要素と前記外側スリーブとの間の電気経路を変更して、前記組織切除デバイスを作動させない、組織切除デバイス。 - 前記絶縁層が前記内側スリーブから摩耗して、前記内側スリーブの一部分を露出させることにより、電気的短絡を生じさせる、請求項1に記載の組織切除デバイス。
- 前記絶縁層が前記内側スリーブから摩耗して、前記内側スリーブの一部分を露出させることにより、インピーダンスの変化を生じさせる、請求項1に記載の組織切除デバイス。
- 前記組織切除デバイスは、プラズマを前記電極要素の電極エッジのところに形成するように構成される、請求項1〜3のいずれか1項に記載の組織切除デバイス。
- 前記絶縁層は、子宮ポリープ組織よりも繊維質である組織を切除するのに使用されるとき、前記内側スリーブから剥離するように構成される、請求項1〜3のいずれか1項に記載の組織切除デバイス。
- 前記絶縁材料は、フッ化エチレンプロピレン(FEP)を含む、請求項1〜5のいずれか1項に記載の組織切除デバイス。
- 前記内側スリーブは、304ステンレススチールを含む、請求項1〜6のいずれか1項に記載の組織切除デバイス。
- 前記外側スリーブは、304ステンレススチールを含む、請求項1〜7のいずれか1項に記載の組織切除デバイス。
- 前記絶縁層は、約0.0127mm〜約0.038mmの厚さを有する、請求項1〜8のいずれか1項に記載の組織切除デバイス。
