Devices, Systems, and Methods and Associated Display Screens for Assessment of Vessels
First 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 the pressure measurements obtained by the first and second instruments on a display, the screen display 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.

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.

18. 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 the pressure measurements obtained by the first and second instruments on a display in communication with the processing system, the screen display 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. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
