Description
本発明は、モジュラー式経皮弁デバイスの展開および組み立てのためのシステムおよび方法に関する。特に、このモジュラー式弁デバイスは、弁モジュールの折り畳みおよび組み立てを容易にする新規な特徴を有するものであり、このシステムは、デバイスモジュールを展開し、結合して一体に固定するための新規な特徴を有するものである。
人体には、たとえば、心臓弁、噴門(食道/胃)弁、腸弁、リンパ系内の弁など、広範な種類の生来の弁がある。生来の弁は、疾病、年齢などのさまざまな理由により変性することがある。機能不全を生じた弁は、最小圧力損失での単一方向の体液の流れを維持することができない。機能不全を生じた弁とは、たとえば、狭窄(すなわち弁小葉が完全に開かない)状態、または、閉鎖不全(すなわち弁小葉が適切に閉まらない)状態が疑われる心臓弁である。弁が関係している器官が正常に機能している状態を取り戻すためには、弁の機能を回復することが望ましい。たとえば、心臓における正常な弁機能によって、弁を介して最小圧力欠損での単一方向の血流を確実に維持することができるので、血液循環と血圧を維持することが可能となる。同様に、正常な食道弁機能によって、酸性胃液分泌が食道内層に対して炎症を生じさせたり永久的に損傷を与えたりすることがないよう担保されている。
