Description
本発明は、2001年4月24日出願の、同時係属中の米国特許出願番号09/841,968、表題「Method and Apparatus for Catheter−Based Annuloplasty」(これは、本明細書中でその全体が参考として援用される)の部分継続である。
(1.発明の分野)
本発明は、一般に、僧帽弁漏出のような僧帽弁機能不全を処置するための技術に関する。より具体的には、本発明は、最小限侵襲性の様式で、漏出性僧帽弁を処置するためのシステムおよび方法に関する。
うっ血性心不全(CHF)(これは、しばしば、心臓の拡張を伴う)は、主要な死亡原因である。結果として、CHFの処置についての市場は、ますます拡大している。例えば、CHFの処置は、米国において医療保険および国民医療保障のドルの主要な出費である。代表的に、CHFの処置は、CHFに罹患した多数の人が、改善された生活の質を楽しむことを可能にする。
本発明は、輪状形成を実施する非侵襲性の方法に関する。本発明の1つの局面に従って、輪状形成を実施するための方法は、心臓の左心室にアクセスしてこの左心室に別個のひだ形成要素(discrete plication element)を提供する工程、およびこのひだ形成要素を心臓の僧帽弁付近の組織に係合する工程を包含する。ひだ形成要素を係合する工程は、このひだ形成要素を、組織の一部を集めてひだを作製する工程を包含する。1つの実施形態において、心臓の左心室にアクセスしてひだ形成要素を提供する工程は、カテーテル配置を使用して、この心臓の左心室にアクセスする工程を包含する。
侵襲性の開放心臓外科手術は、一般的に僧帽弁漏出の処置において効果的である。しかし、開放心臓外科手術は、幾人かの患者(例えば、非常に不健康であるとみなされる虚弱な患者)にとって特に有害となり得、そして他の患者(例えば、無症候性の患者および外科的手順の実施を望まない患者)にとって所望され得ない。従って、僧帽弁の漏出またはより一般的な僧帽弁不全を矯正するための開放心臓外科手術は、僧帽弁漏出を減少させるか、または排除することより改善される可能性のあるを得る多くの患者にとって適切ではない。
Claims (3)
- 輪状形成術を実施するための方法に使用するシステムであって、該システムは、
カテーテルおよび第一ひだ形成要素を含み、該第一ひだ形成要素は、複数のバー部分と、糸と、ロックとを含み、前記パー部品およびロックは、前記糸に結合されており、前記方法は、
心臓の左心室を通して心臓の僧帽弁の近傍に位置する組織に前記カテーテルを使用してアクセスし、
前記カテーテルを通して前記第一ひだ形成要素を提供し、
前記第一ひだ形成要素およびカテーテルを使用して前記組織に第一別個のひだ形成を生じさせ、前記第一ひだ形成要素は、僧帽弁の弧長を小さくするように位置決めされ、前記第一ひだ形成要素およびカテーテルを使用して前記組織に第一別個のひだ形成を生じさせるシステムにおいて、前記方法は、
(a)前記組織を貫通して前記組織の心房側に前記バー部分を位置決めし、
(b)前記糸を緊張させて前記組織の心房側に当てて前記バー部分を位置決めし、
(c)前記組織の心室側に当てて前記ロックを位置決めし、前記組織の心室側に当てて前記ロックを位置決めすることによって、実質的に前記バー部分と前記ロックとの間に前記第一ひだ形成を生じさせることを特徴とするシステム。 - 前記カテーテルは、前記第一ひだ形成要素に前記第一別個のひだ形成を生じさせるように構成されていることを特徴とする請求項1に記載のシステム。
- 前記システムは、第二ひだ形成要素をさらに含み、前記方法は、
前記第二ひだ形成要素を使用して前記組織に第二別個のひだ形成を生じさせ、前記第二ひだ形成要素は、前記第一ひだ形成要素から実質的に分離されていることを特徴とする請求項1に記載のシステム。
