MULTIFUNCTIONAL GUIDEWIRE ASSEMBLIES AND SYSTEM FOR ANALYZING ANATOMICAL AND FUNCTIONAL PARAMETERS

摘要

Multifunctional guidewire assemblies and system for analyzing anatomical and functional parameters are described. Using a single guidewire, functional and anatomical measurements and identification of lesions may be made. Functional measurements such as pressure may be obtained with a pressure sensor on while anatomical measurements such as luminal dimensions may be obtained by utilizing an electrode. The vascular network and stenosed lesions may be modeled into an equivalent electrical network and solved based on the measured parameters. Treatment plan options may be constructed where each plan may correspond to the treatment of a subset of particular lesions. The anatomical outcome for each treatment plans may be estimated and the equivalent modified electrical parameters may be determined. Then, each of the electrical networks for each plan may be solved to determine the functional outcome for each treatment plan and the outcomes for all treatment plans may be presented to a physician.
