An apparatus and method of assessing a narrowing in a fluid filled tube having a fluid flow pressure wave having a backward-originating pressure component and a forward-originating pressure component without taking a flow velocity measurement, comprising: taking pressure measurements in the tube; separating the pressure components into the backward-originating pressure component and the forward-originating pressure component; identifying a time window when the differential of flow velocity (dU) is minimal or absent; and deriving the backward and forward pressure components for pressure measurements taken in at least the time window.

Devices, systems, and methods for visually depicting a vessel and evaluating treatment options are disclosed.

Devices, systems, and methods for assessment of vessels

We provide an imaging system for use in a fluoroscopy procedure carried out on a subject, the imaging system being configured to receive images of a portion of the subject from an image acquisition device, the imaging system comprising an interface module for displaying images received from the image acquisition device to a user, and an optimisation module for determining, based on an image received from the image acquisition device, one or more properties of the image, wherein the optimisation module is configured to output a control routine.

Imaging system for use in a fluoroscopy procedure

Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent.

Devices, systems, and methods for assessing a vessel

A system and method for characterising a narrowing in a fluid filled tube, the system comprising: a probe having a first measurement sensor to take an instantaneous measurement at different locations along the tube; a mechanism to draw the probe through the tube; a position measure to provide location data relating to the location at which a respective instantaneous measurement is taken by the first measurement sensor; a processor to calculate, from the instantaneous measurements, a characteristic of the tube at different locations along the tube.

Devices systems and methods for assessment of vessels

The present disclosure relates generally to the assessment and treatment of vessels, including for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). For example, some embodiments of the present disclosure are suited for identifying the available intervention technique(s) suitable to achieve a desired outcome selected or input by a user. For example, in some implementations a method comprises receiving pressure measurements obtained by one or more intravascular pressure-sensing instruments positioned within a vessel of a patient; receiving an input from a user regarding a desired pressure value for the vessel of the patient; identifying an available treatment option based on the received pressure measurements and the desired pressure value; and outputting, to a display device, a screen display including a visual representation of the available treatment option. Related devices and systems are also described.

Devices systems and methods for coronary intervention assessment, planning, and treatment based on desired outcome

Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent. In some embodiments, the devices, systems, and methods of the present disclosure are configured to assess a vessel by automatically correcting for drift in the equipment utilized to obtain measurements related to the vessel.

Devices, systems, and methods for assessing a vessel with automated drift correction

Devices, systems, and methods for visually depicting a vessel and evaluating treatment options are disclosed. In some instances, a method of evaluating a vessel of a patient includes moving a second instrument longitudinally through a vessel of the patient from a first position to a second position while maintaining a first instrument in a fixed longitudinal position with respect to the vessel; obtaining pressure measurements from the first and second instruments while the second instrument is moved longitudinally through the vessel; visually depicting the vessel on a display based on the obtained pressure measurements; and modifying the visual depiction of the vessel to simulate one or more treatment options. Systems for performing such methods are also provided.
