Abstract:

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.

International Classification:

A61B 5/00
A61B 5/0215
A61B 5/02

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:

Devices, systems, and methods of mapping a vessel system of a patient and identifying lesions therein are disclosed. This includes a method of evaluating a vessel of a patient, the method comprising obtaining image data for the vessel of the patient, obtaining physiological measurements for the vessel of the patient, co-registering the obtained physiological measurements with the obtained image data such that the physiological measurements are associated with corresponding portions of the vessel of the patient, analyzing the co-registered physiology measurements to determine a classification of a lesion within the vessel of the patient, and outputting, to a user interface, the classification of the lesion. Other associated methods, systems, and devices are also provided herein.

Abstract:

What is described is an apparatus for intravascular pressure measurement, comprising an elongate body and a first pressure sensor. The elongate body includes a proximal portion and a distal portion, the body defines a lumen extending from a proximal end to a distal end of the body, the lumen is sized and shaped to allow the passage of a guidewire therethrough, and the body includes an annular wall extending from the lumen to an outer surface of the body. The first pressure sensor is disposed entirely within the wall of the distal portion of the body, and the pressure sensor includes a sensor cover coupled to the wall. An exterior surface of the sensor cover and the outer surface of the body are substantially aligned.
