    摘要： A system includes a processor circuit in communication with an extraluminal imaging device and an intraluminal imaging device. The processor circuit obtains an enhanced stent deployment extraluminal image and a plurality of intraluminal images. The enhanced stent deployment extraluminal image and the each of the plurality of intraluminal images are associated with locations along a pathway. The pathway is overlaid over an extraluminal image. Based on the locations of the pathway, the processor circuit coregisters the plurality of intraluminal images to the enhanced stent deployment extraluminal image and outputs a screen display of one of the plurality of intraluminal images and the enhanced stent deployment extraluminal image with an indicator identifying the location at which the displayed intraluminal image was obtained. The processor circuit may also determine an expansion score for intraluminal images depicting the stent and identify regions of the stent corresponding to an expansions score below a threshold.

    摘要： A system includes a processor circuit in communication with an intraluminal imaging device and a laser atherectomy device. An intraluminal imaging procedure is performed within a lumen with the intraluminal imaging device. The processor circuit receives the intraluminal images acquired. The intraluminal images are analyzed to determine a tissue classification for each intraluminal image. One or more laser atherectomy settings are determined for each intraluminal image based on the tissue classification. The intraluminal images and corresponding tissue classifications and laser atherectomy settings are then associated with the location at which each intraluminal image was acquired along the lumen. A laser atherectomy procedure is then performed within the same lumen. As the laser atherectomy device is moved to positions within the vessel, the laser atherectomy setting associated with each position is retrieved from the memory and automatically applied to the laser atherectomy device.

    摘要： 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.
