PROCEDES, DISPOSITIFS ET SYSTEMES DE DETECTION, DE MESURE ET/OU DE CARACTERISATION DE CHANGEMENTS DE CONFORMITE ET/OU D'ELASTANCE DE VAISSEAU ET/OU DE LESION PENDANT DES INTERVENTIONS VASCULAIRES
The present system is directed in various embodiments to methods, devices and systems for sensing, measuring and evaluating compliance and/or elastance in a bodily conduit. In other embodiments, the methods, devices and systems sense, measure, determine, display and/or interpret compliance and/or elastance in a bodily conduit and/or a lesion within the bodily conduit using fractional flow reserve and/or flow velocity measurements as well as resistance to flow calculations in certain embodiments. In all embodiments, the sensing, measuring, determining, displaying and/or interpreting may occur before, during and/or after a procedure performed within the bodily conduit. An exemplary conduit comprises a blood vessel and an exemplary procedure comprises a vascular procedure such as atherectomy, angioplasty, stent placement and/or biovascular scaffolding.
