Bedside controller for assessment of vessels and associated devices, systems, and methods
Devices, systems, and methods for evaluating a vessel of a patient are provided. The method includes outputting, to a touch-sensitive display of a bedside controller, a screen display including: a visual representation of a first pressure ratio of pressure measurements obtained by first and second instruments positioned within a vessel while the second instrument is moved from a distal position to a proximal position relative a stenosis and the first instrument remains stationary; and a first proximal pressure waveform and a first distal pressure waveform; receiving, through the touch-sensitive display of the bedside controller, a user touch input on the first proximal pressure waveform and/or the first distal pressure waveform identifying a time at which pressure measurements were obtained; and modifying the screen display, in response to the user touch input, to further include a visual representation of the obtained pressure measurements corresponding to the identified time.
1 . A system for evaluating a vessel of a patient, comprising:
a bedside controller comprising a processor and a touch-sensitive display, wherein the bedside controller configured to:
output a plurality of modes to the touch-sensitive display, wherein the plurality of modes comprises a first intravascular modality and a second intravascular modality;
receive, via the touch-sensitive display, a user touch input for selection of a mode from the plurality of modes;
in response to the user touch input for selection of the mode comprising a selection of the first intravascular modality:
control a first intravascular catheter or guidewire to obtain first intravascular data associated with the first intravascular modality from the vessel;
receive the first intravascular data from the first intravascular catheter or guidewire;
output, to the touch-sensitive display, a first screen display based on the first intravascular data;
receive, via the touch-sensitive display, a user touch input for modification of the first screen display; and
modify the first screen display in response to the user touch input for modification of the first screen display;
in response to the user touch input for selection of the mode comprising a selection of the second intravascular modality:
control a second intravascular catheter or guidewire to obtain second intravascular data associated with the second intravascular modality from the vessel;
receive the second intravascular data from the second intravascular catheter or guidewire;
output, to the touch-sensitive display, a second screen display based on the second intravascular data;
receive, via the touch-sensitive display, a user touch input for modification of the second screen display; and
modify the second screen display in response to the user touch input for modification of the second screen display.
2 . The system of claim 1 , wherein the first intravascular modality comprises an intravascular pressure modality.
3 . The system of claim 2 , wherein the intravascular pressure modality comprises a pressure ratio.
4 . The system of claim 3 , wherein the pressure ratio comprises a fractional flow reserve (FFR) or an instant wave free ratio (iFR).
5 . The system of claim 2 , further comprising:
the first intravascular catheter or guidewire.
6 . The system of claim 5 , wherein the first intravascular catheter or guidewire comprises a pressure-sensing element.
7 . The system of claim 1 , wherein the second intravascular modality comprises an intravascular imaging modality.
8 . The system of claim 7 , wherein the intravascular imaging modality comprises intravascular ultrasound (IVUS) or optical coherence tomography (OCT).
9 . The system of claim 7 , further comprising:
the second intravascular catheter or guidewire.
10 . The system of claim 9 , wherein the second intravascular catheter or guidewire comprises an imaging element.
