Devices, systems, and methods and associated display screens for assessment of vessels
DCFirst Claim
1. A method of evaluating a vessel of a patient, comprising:
- obtaining pressure measurements from first and second instruments positioned within a vessel of a patient while the second instrument is moved longitudinally through the vessel from a first position to a second position and the first instrument remains stationary within the vessel; and
outputting a screen display having visual representations of a pressure ratio calculated using the pressure measurements obtained by the first and second instruments on a display, the screen display including;
a numerical value of the pressure ratio; and
a graph of the pressure ratio over a time the second instrument is moved longitudinally through the vessel from the first position to the second position.

Abstract
Devices, systems, and methods for visually depicting a vessel and evaluating treatment options are disclosed. The methods can include obtaining pressure measurements from first and second instruments positioned within a vessel of a patient while the second instrument is moved longitudinally through the vessel from a first position to a second position and the first instrument remains stationary within the vessel; and outputting a visual representation of the pressure measurements obtained by the first and second instruments on a display, the output visual representation including a graphical display of a pressure ratio of the obtained pressure measurements and at least a portion of a pressure waveform of the obtained pressure measurements identifying a diagnostic period utilized in calculating the pressure ratio.

8. A system for evaluating a vessel of a patient, comprising:
a processing system in communication with first and second instruments sized and shaped for introduction into the vessel of the patient, the processing unit configured to; obtain pressure measurements from the first and second instruments while the second instrument is moved longitudinally through the vessel of the patient from a first position to a second position while the first instrument is maintained in a fixed longitudinal position with respect to the vessel; and output a screen display having visual representations of a pressure ratio calculated using the pressure measurements obtained by the first and second instruments on a display in communication with the processing system, the screen display including; a numerical value of the pressure ratio; and a graph of the pressure ratio over a time the second instrument is moved longitudinally through the vessel from the first position to the second position. - View Dependent Claims (9, 10, 11, 12, 13, 14)
