Stent and Vessel Visualization and Diagnostic Systems, Devices, and Methods

Abstract

In part, the disclosure relates to computer-based methods, devices, and systems suitable for pre-stent planning, stent planning and post-stent planning using one or more computing devices. In one embodiment, a method generates one or more stent profiles, such as a target stent profile, that are user configurable during a pre-stent planning stage by selecting one or more frames. The method performs a comparative analysis of the previously set target stent profile relative to a vessel lumen region post stent deployment. The method and related user interfaces can alert a user to move, remove, reposition, or inflate a stent. The location of jailed side branches can also be identified and displayed based upon the comparative analysis. Parameters that change based on the outcome of the stent deployment can be displayed in terms of the predicted parameter value and the value that is measured or determined after stent deployment.
