Description
拡張可能な構造体と、
心臓の心耳の小孔にわたって広がるように適応した、拡張可能な構造体の上に配置されるカバーと、
を含む、カテーテルに対して放出可能に取り付けることができる医療用移植装置によって実現され、
拡張可能な構造体は、外部のエネルギー源からエネルギーを受けるように構成され、さらに、拡張可能な構造体が拡張された状態にある場合にその周囲にある心臓の組織を加熱して心臓の組織の電気的特性を、導電性から電気絶縁性に変化させるため等、その周囲にエネルギーを伝えるように構成され、それにより、医療用移植装置による心耳の持続性の閉塞をもたらす。
カテーテルを用いて、本発明による医療用移植装置を心臓内に導入するステップと、
心臓の心耳内で医療用移植装置を展開させるステップと、
を含み、
医療用移植装置は、外部のエネルギー源からエネルギーを受け、
医療用移植装置は、拡張可能な構造体が拡張された状態にある場合にその周囲にある心臓の組織を加熱して心臓の組織の電気的特性を、導電性から電気絶縁性に変化させるため等、心臓の組織にエネルギーを伝え、それにより、展開された医療用移植装置による心耳の持続性の閉塞をもたらす。心臓に医療用移植装置を導入し、さらに、心臓の心耳内の正しい位置にて展開させることは、カテーテルによって可能になる。医療用移植装置は、カテーテルを通った、又は、患者の体を介して伝えられるエネルギーを外部のエネルギー源から受けてもよい。医療用移植装置に隣接する心臓の組織を加熱することによって、心耳を心臓の残りの部分から電気的に分離することができ、その結果、心房細動の維持及び永続化のための基質の大きさを患者において有意に減らすことができる。
医療用移植装置に統合されたセンサに隣接する心臓の組織の温度及び/又は電気信号を測定し、
測定された温度及び/又は電気信号に基づき、コントローラコンピュータによって、医療用移植装置に外部のエネルギー源から伝えられるエネルギーの量、及び/又は、医療用移植装置の外周の周囲にあるセグメントの起動シーケンス(activation sequence)を制御する
ようにさらに構成される。コントローラコンピュータは、医療用移植装置に外部のエネルギー源から伝えられるエネルギーの量、医療用移植装置の周囲によって要求される温度分布、又は、医療用移植装置の外周の周囲のセグメントの起動シーケンス等のパラメータの選択を可能にするコンピュータプログラムを含む。
