Abstract: Pressure sensing guidewires and methods for making and using pressure sensing guidewires are disclosed. An example pressure sensing guidewire may include a tubular member having a proximal region and a housing region. An optical fiber may be disposed within the tubular member and extend to the housing region. The optical fiber may have a distal end region with a cavity formed therein. A polymeric member disposed within the cavity. A reflective surface disposed along the polymeric member.

Abstract: A method, device, and system for evaluating a vessel of a patient, and in particular the hemodynamic impact of a stenosis within the vessel of a patient. Proximal and distal pressure measurements are made using first and second instrument while the first instrument is moved longitudinally through the vessel from a first position to a second position and the second instrument remains in a fixed longitudinal position within the vessel. A series of pressure ratio values are calculated, and a pressure ratio curve is generated. One or more stepped change in the pressure ratio curve are then identified and/or located using an Automatic Step Detection (ASD) process and/or algorithm. The ASD includes identifying a general position of a starting point of the stepped change by identifying a change in the pressure ratio values within a first window along the pressure ratio curve that is at or above a first threshold change value, and identifying an optimized position of the starting point by identifying a change in the pressure ratio values within a second window along the pressure ratio curve that is at or above a second threshold change value, wherein the second window is smaller than the first window, and the second threshold change value is smaller than the first threshold change value.

Abstract: The present disclosure provides to co-register intravascular images of a vessel with one or more extravascular images of the vessel in real-time, such as, during acquisition of the extravascular images. Key points in a first frame of the extravascular images can be identified and then tracked across other frames of the extravascular images. The intravascular images can be co-registered to a frame (or frames) of the extravascular images based on the locations of the key points in the frame.

Abstract: The present disclosure provides to generate a side branch mask from an extravascular image of a vessel using an ensemble of machine learning (ML) models. The side branch mask can be generated by inferring, using several initial ML models, indications of side branches from an image frame and inferring, using a post-processing ML model, the side branch mask from the indication of side branches.

Abstract: The present disclosure provides to process intravascular ultrasound (IVUS) images from different runs through a vessel to generate a mapping between frames of each IVUS run and to generate a graphical user interface (GUI) to graphically present the IVUS runs in relationship to each other. In some examples, a vessel fiducial is identified in a frame of each IVUS run and one or both runs are offset in time, distance, and/or angle to align the frames with the identified vessel fiducial. Further, the disclosure provides to angularly align intravascular images to a viewing perspective of an external image of the vessel.

Abstract: This disclosure provides alternative medical imaging systems and methods for vascular imaging co-registration. Methods include obtaining extravascular imaging data of a portion of a blood vessel including an extravascular image showing an intravascular imaging device disposed within the vessel with an imaging element disposed at a starting location for a translation procedure. The extravascular image also includes an extravascular contrast image showing the portion of the blood vessel with contrast showing a visualized anatomical landmark. Intravascular imaging data is obtained during the translation procedure that includes one or more intravascular images showing a detected anatomical landmark. The starting location and the ending location of the imaging element on the extravascular imaging data is marked, and the predicted location of the detected anatomical landmark on the extravascular imaging data is marked. The predicted location of the detected anatomical landmark is then aligned with the visualized anatomical landmark.

Abstract: Embodiments herein relate to intravascular imaging display systems and related methods. In an embodiment, an intravascular imaging display system is included having a control circuit and a video output circuit. The video output circuit can be configured to generate a display output including a user interface. The user interface can include graphical elements related to a vessel being imaged. The graphical elements can include a first detected feature portion at least partially defined by a first graphic indicator and a second detected feature portion at least partially defined by a second graphic indicator. The first graphic indicator can be visually distinct from the second graphic indicator. The first detected feature portion and the second detected feature portion can be assigned to represent one or more locations along a vessel wall by the control circuit based on a degree of attenuation of an ultrasound return signal crossing a threshold value.

Abstract: The present disclosure provides apparatus and methods to both infer stent expansion (vessel expansion or compliance) and probability of procedural success (vessel patency) from pretreatment diagnostic imaging at the point-of-care and also train an inference model to generate such an inference, thus allowing a physician to choose with greater certainty an optimal treatment tool and treatment protocol for treating a vessel of a patient.

An image is obtained showing the position of the first instrument within the vessel that corresponds to the identified stepped change. The image is registered to the identified stepped change in the pressure ratio curve. The image may be output to the display.
