Description
本出願は、2013年3月14日に出願された米国特許出願、出願番号61/784,973の35USC119(e)の下の利益を主張するものであり、その全体が参照により本明細書に組み込まれる。
1.弁把握器及び支持フレーム
支持フレーム5に移動可能に取り付けられた弁把握器は、弁把握器10、拡張可能な支持フレーム15及び縫合糸ループ60を含む。弁把握器10は、3つの脚部材30を備え、この各々は、縫合糸ループ60がその長手方向軸に沿ってスライド可能な内腔50を有している。図1は、本明細書に記載の「係合位置」を表す。図2は、支持フレーム15の配置前に、弁把握器10と支持フレーム15が、自然の弁輪内に適切に配置される(本明細書中に記載の「入れ子位置」)場合の様に、支持フレーム15が弁把握器10と位置合わせされる実施態様を示す。
II.大動脈人口弁を搬送するための人口弁搬送装置
搬送の方法
III. 人工心臓弁のカテーテルベースの搬送のための外科用搬送装置
搬送のための方法
