Description
本発明の非限定的な実施形態が、添付の図を参照して例として説明される。添付の図は概略的であるとともに縮尺通りであることを意図されるものではない。図において、示された各同一又は略同一のコンポーネントは、典型的には単一の数字により表されている。明瞭さを目的として、全てのコンポーネントが全ての図においてラベル付けされているわけではなく、当業者が本発明を理解することを可能にするために例証が必要ではない場合各実施形態の全てのコンポーネントが示されているわけでもない。
明細書における「実施形態」、「いくつかの実施形態」、「他の実施形態」等への言及は、説明された実施形態は特定の特徴、構造、又は特性を含み得るが、全ての実施形態が特定の特徴、構造又は特性を必ずしも含まなくてもよいことを示すことに留意されたい。さらに、そのようなフレーズは、必ずしも同じ実施形態に言及していなくてもよい。さらに、特定の特徴、構造、又は特性が実施形態との関連において説明されるとき、明らかにそうではないと述べられない限り、明確に説明されたかどうかにかかわらず、他の実施形態と関連してそのような特徴、構造、又は特徴に影響を及ぼすことは、当業者の知識の範囲内である。すなわち、以下に記載の様々な独立した要素は、特定の組合せにおいて明確に示されていない場合であっても、それにも拘わらず、当業者により理解されるであろうとおり、他の追加的な実施形態を形成するため又は説明された実施形態を補完する及び/若しくは高めるために互いに組合せ可能又は配置可能であると想定される。
図5Aは、本明細書において説明されたシステムにおいて使用され得るフレーム部分500を示し、ストラット510及び520の対を示す。ストラット510は、弁輪への留置の間にアンカー514を支持するために、図3Bに関して説明されたとおりに構成され得るアンカースリーブ512を含むように示される。ストラット520は、同様に、留置の間アンカー524を支持するためにアンカースリーブ522を含むように示される。各アンカー514、524は、それぞれのアンカーヘッド516、526を含むように示されており、該アンカーヘッド516、526は、関連するアンカーをそれぞれの駆動チューブ518、528に結合する。一実施形態によれば、駆動チューブは、回転駆動チューブからなる。該回転駆動チューブは、駆動チューブの回転が、結合されたアンカーを遠位側に動かすように構成される。一実施形態において、アンカー514、524は螺旋コイルからなり、各螺旋コイルは、アンカーの遠位チップからそれぞれのアンカーヘッド516、526を通って延びるアンカールーメンを画定する。
調整後、結合されたアンカーの相対的位置は、締付コード、例えば、例えばナイロンフィラメントなど締付ワイヤ及び/又は縫合材料などを使用して結合されたアンカーのアンカーヘッドを結合することにより、拘束され得るか又は他の方法で固定され得る。
