Description
本出願は、2013年1月25日出願の特許出願「A medical device and method for facilitating selection of an annuloplasty implant」、2013年1月25日出願の特許出願「A valve for short time replacement, for taking over the function of and/or for temporary or partial support of a native valve in a heart」、2013年1月25日出願の特許出願「A medical system, and a device for collecting chordae and/or leaflets」、及び2013年1月25日出願の特許出願「Temporary atrium support device」に関するものである。
本発明は、全体的に心臓弁修復の分野に関する。より具体的に、本発明は僧帽弁修復に関する。
心臓弁修復は、時間的に厳しく且つ困難な手順であるということが知られている。今日における既知のシステムと方法は、作業に長時間を要し、且つ、作業を行う医療スタッフには非常に高度なものである。それ故、患者の生命は、医療スタッフの技術と、心臓弁に関連した問題の発見の時間に大いに依存する。
本発明の具体的な例はここで、添付の図面を参照すると共に記載される。しかし、本発明は、多くの異なる形態で実施され得るものであり、且つ、本明細書で説明される例に限定されると解釈されるべきではない。むしろ、これらの例は、本開示が徹底的且つ完全なものとなり、且つ本発明の範囲を当業者に十分に伝えるように、提供される。添付の図面にて例証される例の詳述において使用される用語は、本発明を制限するようには意図されていない。図中、同様の数字は、同様の要素を指す。
