    Abstract: Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to assess the severity of a stenosis in the coronary arteries without the administration of a hyperemic agent. Further, in some implementations devices, systems, and methods of the present disclosure are configured to normalize and/or temporally align pressure measurements from two different pressure sensing instruments. Further still, in some instances devices, systems, and methods of the present disclosure are configured to exclude outlier cardiac cycles from calculations utilized to evaluate a vessel, including providing visual indication to a user that the cardiac cycles have been excluded.

    Abstract: Devices, systems, and methods automatically detecting anomalous waveforms and eliminating these waveforms from physiologic measurements are disclosed. For example, in some instances a method includes collecting a pressure data from an intravascular device positioned within the vessel of the patient, the pressure data including a pressure waveform for each cardiac cycle of the patient; comparing the pressure waveform for each cardiac cycle of the patient to a reference pressure waveform to identify an anomalous pressure waveform; and calculating a pressure ratio utilizing the pressure data from the intravascular device, wherein data from the anomalous pressure waveform is excluded from the calculation.

    Abstract: In one embodiment, a sensing guidewire for performing atraumatic intravascular physiologic measurements includes an elongated core wire and a sensor disposed at a distal end portion thereof. A flexure is disposed in the core wire proximal to the sensor housing. The flexure is substantially more flexible than regions of the core wire disposed on either side of the flexure, and enables a distal end portion of the guide wire to conform to and rest against a wall of vascular structure, such as an aneurism, without exerting an undue outward pressure thereon in response to making any contact with the wall.

    Abstract: Devices, systems, and methods of evaluating risk associated with a condition of the vessel and providing an objective intervention recommendation based on the evaluated risk are disclosed. The method includes steps of obtaining physiologic measurements 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 from a first position to a second position, obtaining image data from an image of a vessel system, co-registering the physiologic measurements with the image data to produce co-registered physiologic measurements, and determining whether to perform a first surgical procedure or a second surgical procedure, wherein the determining is based on the co-registered physiologic measurements. Other associated methods, systems, and devices are also provided herein.
