Abstract
Description
この出願は、2018年12月21日に出願された仮出願第62/783,902号、2018年12月21日に出願された仮出願第62/783,935号、2019年5月9日に出願された仮出願第62/845,386号、2019年8月30日に出願された仮出願第62/894,260号及び2019年9月16日に出願された仮出願第62/901,105号の利益を主張し、これらをすべて、あらゆる目的のためにその全体の参照により本明細書に取り込む。
本開示は、患者を治療するためのシステム、より具体的には、生理学的測定を使用して薬物の投与を決定するためのシステム及び方法に関する。
過去10年の間に、米国における冠状動脈死の数は、医学及び治療の進歩のおかげで着実に減少したが、心不全による死亡の相対的な数は増加し、より多くの人々がこれまで以上に心不全の高いリスクとともに生きていることを示している。一般に、心不全は心臓が体に十分な血液を供給できないときに発生する。その結果、体積排出量が少ないと、排出力の不足を補うのを支援するために左心の充満圧が高くなる。より少量の体積排出量はまた、腎臓又は腎臓の灌流の減少を含む、より低い臓器灌流を引き起こす。腎臓の灌流が減少すると、過剰な流体が保持されることがありうる。急性代償不全発症は、体液レベルが上昇したり、及び/又は、血管の血液分布が低下したりして、患者が倦怠感及び呼吸困難(呼吸困難)を経験し、病院に送る状態になることである。治療せずに放置すると、深刻な合併症を引き起こし、死に至る可能性がある。
本明細書に開示されるのは、行われた測定に基づいて患者への薬物の投与を決定するための医療システム及び方法である。
添付の図面は、本開示のさらなる理解を提供するために含まれ、本明細書に取り込まれ、その一部を構成し、実施形態を示し、記載とともに、本開示の原理を説明するのに役立つ。
定義及び用語
本開示は、限定的な方法で読まれることを意図するものではない。例えば、本出願で使用される用語は、その分野の用語がそのような用語に帰する意味の文脈で広く読まれるべきである。
本開示の様々な態様は、心臓の左側及び右側で生理学的測定を行うためのデバイスなどのインプラント可能なメディカルデバイスを対象とする。特定の例において、本開示の様々な態様は、圧力測定を行うための方法及び装置に関する。さらに、本開示はまた、行われる測定に基づいて患者への薬物の投与を決定するための医療システムを含む。
