Abstract
【解決手段】血流予備量比(FFR)を決定するのに適した方法、装置、及びシステム、並びにそれらの様々の変形に関し、狭窄14を有する血管12内の補正されたFFRを取得するための方法及び装置に関し、狭窄を有する血管の補正されたFFRを測定するための装置に関する。装置は、光コヒーレンス断層撮影組立体及び圧力組立体を含むプローブと、光コヒーレンス断層撮影組立体及び圧力組立体と連絡するプロセッサとを含む。圧力組立体は、血管の所定の場所における圧力の値を測定し、それらをプロセッサに通信する。圧力測定における干渉を減少させるために二重ガイドワイヤが使用される。

Description
この出願は2011年5月27日に出願された米国仮特許出願第61/490,925号及び2011年8月31日に出願された米国仮特許出願第61/529,594号の利益及び優先権を主張し、それらの全文を参照としてここに援用する。
部分的に、本発明は、カテーテルのような、パージポートを有するデータ収集プローブの一部のパージ(除去)を行い、且つパージポート圧力測定を行うするのに適した、システム、方法、及び装置にも関する。この種の測定を図18に関して上で議論した。1つの実施態様では、パージポートと流体連絡する圧力測定装置を使用することによって、空腔内に配置されるパージポートを通じて、血管の空腔のある位置での圧力を測定し得る。図20乃至23に示すようなパージング及び圧力測定を行うために、様々の種類の流体供給又は流れ規制システム又は構成部品を使用し得る。図18に示すシステム又は構成部品と共に、或いは図18に示すシステム又は構成部品の代わりに、これらのシステム及び構成部品の一部を使用し得る。
プロセッサ(例えば、マイクロプロセッサ、マイクロコントローラ、デジタル信号プロセッサ、又は汎用コンピュータ)と共に使用するためのコンピュータプログラム論理、プログラム可能な論理装置(例えば、現場でプログラム可能な論理列(FPGA)又は他のPLD)と共に使用するためのプログラム可能な論理、別個の構成部品、集積回路(例えば、特定用途向け集積回路(ASIC))、又はそれらの任意の組合せを含む任意の他の手段を非限定的に含む多くの異なる形態において、本発明を具現し得る。本発明の典型的な実施態様において、OCTプローブ及びプロセッサに基づくシステムを使用して収集されるデータの処理の一部又は全部は、一組のコンピュータプログラム命令として実施され、コンピュータプログラム命令は、コンピュータ実行可能な形態に変換され、例えば、コンピュータ読取り可能な媒体内に記憶され、且つオペレーティングシステムの制御の下でマイクロプロセッサによって実行される。よって、問合わせ応答及び入力データは、OCTデータ、OCT画像、血管抵抗、FFR計算、圧力感知、輪郭検出、並びに上述の他の機能及び実施態様を生成するのに適した、プロセッサが理解可能な命令に変換される。
Claims (1)
