以下の実施例は、本明細書で開示されるシステムおよび方法の実施形態をさらに例証し、決してそれらの範囲を限定するものとして解釈されるべきではない。
直線状治療要素を含み、4ワットの最大電力を使用する、双極システムを用いた切除体積
直線状ポリマーシャフト上に搭載された2つの白金・イリジウム(90%/10%)バンドを使用して、双極電極構成を有する卵巣組織装置が作成された。電極の外形は、1.27mmであり、長さは、3.0mmであった。電極は、相互から3.0mm離間され、温度センサが各電極の内径上に搭載された。損傷(切除組織)サイズを評価するために、生の鶏の胸肉が電極の周囲に配置され、RF発生器がエネルギーを電極に送達する一方で、他方の電極が発生器への帰還経路の一部として使用された。RFエネルギーが、約80℃の標的温度を達成するために30秒間送達された。観察された最大電力は、約4ワットであった。結果として生じる損傷の断面(縦方向の切断)は、幅3.8mmおよび長さ10.4mmである明白な組織壊死を示した。(3.8mmの直径および10.4mmの長さ、ならびに1/4×π×D2×Lの体積を伴う)円筒として損傷体積を概算すると、損傷は、118mm3の切除組織の体積を有すると計算された。本実験は、直線状治療要素を用いて行われたが、曲線状治療要素を使用して、類似結果が予期されるであろう。
直線状治療要素を含み、10ワットの最大電力を使用する、双極システムを用いた切除体積
類似実験が、実施例1で説明される同一の電極構成を用いて行われた。しかしながら、本実施例では、RFエネルギーが合計15秒間送達され、約100℃の最高温度を標的にした。この場合に利用された最大電力は、約10ワットであった。結果として生じる損傷の断面は、4.5mmの主軸D1および3.9mmの短軸D2を伴う楕円に近似する、明白な組織壊死を示した。10mmの損傷長を仮定すると、結果として生じる損傷体積は、138mm3(体積=1/4×π×D1×D2×L)として計算された。
曲線状治療要素を含む双極システムを用いた切除体積
実験が、実施例1で説明されるような類似双極電極構成を利用して行われた。しかしながら、電極は、7mmの近似半径を伴う曲線状ポリマーシャフト上に搭載された。白金・イリジウム(90%/10%)電極は両方とも、1.27mmの外径および3.0mmの長さを有した。電極は、相互から3.0mm離間され、温度センサが各電極の内径上に搭載された。一実験では、RFエネルギーが、約90℃の標的温度を達成するために30秒間送達された。結果として生じる損傷の断面(縦方向の切断)は、幅6.7mmである明白な組織壊死を示した。別の実験では、RFエネルギーはまた、約90℃の標的温度を達成するために30秒間送達された。結果として生じる損傷の断面は、6.0mmの主軸D1および3.8mmの短軸D2を伴う楕円に近似する、明白な組織壊死を示した。9mmの損傷長を仮定すると、結果として生じる損傷体積は、161mm3(体積=1/4×π×D1×D2×L)として推定されることができる。
さらに、それらの示された組み合わせのうちのいずれかを含む、以下の実施例が、本明細書で開示され、本開示の範囲内に含まれる。
a)卵巣組織装置であって、卵巣組織装置は、ドッキングデバイスと、治療要素とを備え、ドッキングデバイスは、伸長本体を備え、近位端と、遠位端とを有し、それを通る管腔を画定し、治療要素は、ドッキングデバイスの管腔内で摺動可能であり、かつそこから展開可能である、卵巣組織装置と、
