PHILIPS IMAGE GUIDED THERAPY CORPORATION

A system is provided that includes a processor circuit in communication with an intravascular imaging catheter. The processor circuit is operable to: receive an intravascular imaging signal; perform, tissue characterization to identify a plaque component of the blood vessel; generate an intravascular image; receive an extravascular image of a blood vessel; co-register the intravascular image and the extravascular image to associate the intravascular image with a location of the blood vessel in the extravascular image; determine, if a spatial distribution of the plaque component within the intravascular image satisfies a criterion associated with the spatial distribution; and when the spatial distribution satisfies the criterion, output a screen display comprising: the extravascular image; and a first indicator at the location of the blood vessel in extravascular image. The first indicator is representative of the spatial distribution of the plaque component. Associated methods and devices are also provided.

A system includes a processor circuit that receives intravascular imaging data from an intravascular imaging catheter, an x-ray image from an x-ray imaging device, and intravascular pressure data from an intravascular pressure-sensing guidewire. The processor circuit correlates the intravascular imaging data and the intravascular pressure data to locations along a body lumen shown in the x-ray image. The processor circuit generates a longitudinal view of the body lumen based on the intravascular imaging data and outputs a screen display including the longitudinal view of the body lumen with an overlaid graphical representation corresponding to the intravascular pressure measurements.

Disclosed is an intraluminal ultrasound imaging system, including a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive a plurality of intraluminal ultrasound images obtained by the imaging catheter while the imaging catheter is moved through a body lumen of a patient, wherein the plurality of intraluminal ultrasound images comprise axial cross-sectional views of the body lumen. The processor circuit is further configured to generate a stylized graphic of the body lumen based on the plurality of intraluminal ultrasound images, wherein the stylized graphic comprises a longitudinal cross-sectional view of the body lumen, and output, to a display in communication with the processor circuit, a screen display comprising the stylized graphic.

Systems, devices, and methods for displaying multiple intraluminal images in a luminal assessment are provided. An intraluminal imaging device is provided which is configured to be positioned within a body lumen of a patient and receive imaging data associated with the body lumen. The intraluminal imaging device may be in communication with a controller configured to display two or more transverse images of the body lumen on a single display device. The system may also be configured to automatically measure, display, and compare measurements of features, including misalignment or malapposition of a stent, the diameter and area of the stent at various locations along the stent, as well as the diameter and area of the lumen before the stent is positioned.

An intraluminal sensing system is provided, which includes an intraluminal device. The intraluminal device includes a flexible elongate member that can be positioned within a body lumen of a patient, and an ultrasound sensor at a distal portion of the flexible elongate member and configured to emit an ultrasound pulse in a longitudinal direction and to receive ultrasound echoes from the pulse. The system also includes a processor circuit in communication with the ultrasound sensor. The processor circuit is configured to compute a velocity spectrum of particles moving within the body lumen based on the received ultrasound echoes and, based on the velocity spectrum, compute a skew index indicative of a position or alignment of the ultrasound sensor within the body lumen. The processor circuit is also configured to output an indication of the skew index.

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.

Systems, devices, and methods for providing procedure-specific workflow guidance are provided. The workflow guidance may include providing selectable options on a display device to a user including a selectable option to select a target vessel and a prompt to move an intravascular imaging device within the selected target vessel. Imaging data is received from the intravascular imaging device within the selected target vessel. The workflow guidance may be used to identify an area of interest within the selected target vessel and automatically display vessel measurements corresponding with the area of interest on the display device.

A method of evaluating a vessel of a patient is provided. The method includes outputting, to a display device, a screen display including: a visualization based on pressure measurements obtained from a first instrument and a second instrument positioned within the vessel of the patient while the second instrument is moved longitudinally through the vessel and the first instrument remains stationary within the vessel; and a visual representation of a vessel; receiving a user input to modify the visualization to simulate a therapeutic procedure; and updating the screen display, in response to the user input, including modifying the visualization based on the user input. A system for evaluating a vessel of a patient is also provided. The system includes first and second instruments sized and shaped for introduction into the vessel of the patient; and a processing system communicatively coupled to the first and second instruments and a display device.
