Description
本出願は、2013年11月18日に出願された米国仮出願第61/905,430号の優先権の利益を主張し、この仮出願は、参照により本明細書に援用される。
冠動脈血流予備能、冠血流予備量比、及びP−Vループは、動脈内の異なる位置で取られた測定値を必要とし得る。これらのパラメータのための測定値を提供するために、本発明のシステム及び方法は、脈管構造内の機能的流れセンサの大2の位置に対する機能的流れセンサの第1の位置での圧力および流量を評価する。例えば、第1の位置は、検査下の血管のセグメントの遠位であり、第2の位置は、血管のこのセグメントの近位である。2つの位置に渡って得られた測定値は次に、1又は複数の閾値に対して評価され、この閾値は、閉塞が体管腔内に存在するかどうかを決定するために使用され得る。
特許、特許出願、特許公開、雑誌、書籍、論文、ウェブコンテンツのような、他の文献の参照及び引用が、本開示の全体にわたって成されている。全てのこのような文献は、全ての目的のためにそれらの全体が参照により本明細書に援用される。
本発明の様々な修正形態及びそれらの多くのさらなる実施形態は、本明細書に図示され且つ記載されたものに加えて、本明細書で引用される科学文献及び特許文献への参照を含む、この文書の全内容から当業者に明らかになるであろう。本明細書の主題は、様々な実施形態及びそれらの均等物における本発明の実施に適合されることができる重要な情報、例証及び手引きを含む。
