Problems solved by technology

[0005] While solid-state IVUS catheters are simple to use, due to their lack of moving parts, it cannot match the image quality that can be obtained from rotatable IVUS catheters
It is difficult to operate a solid-state IVUS catheter at the same high frequency as a rotatable IVUS device, and the lower operating frequency of the solid-state IVUS catheter translates into poorer resolution compared to the higher frequency operating frequency of a rotatable IVUS catheter

Abstract

An intravascular ultrasound (IVUS) device that includes a flexible elongate member having a proximal portion and a distal portion; a controller coupled to the distal portion of the flexible elongate member; an ultrasound transducer disposed at the distal portion of the flexible elongate member and in communication with the controller; a pressure transducer disposed at the distal portion of the flexible elongate member and in communication with the controller; and plurality of conductors extending from the controller to the proximal portion of the catheter, at least one conductor of the plurality of conductors being configured to carry both the signals representing information captured by the ultrasound transducer and information captured by the pressure transducer.

Description

technical field [0001] The present disclosure generally relates to systems, devices, and methods for using controllers for imaging sensors and pressure sensors for diagnostically evaluating a target region of a patient. More specifically, the present disclosure relates to systems, devices, and methods that utilize a common controller to perform intravascular ultrasound (IVUS) imaging and pressure sensing to diagnostically assess a target region of a patient (eg, the patient's vasculature). Background technique [0002] Intravascular ultrasound (IVUS) imaging is widely used in interventional cardiology as a diagnostic tool for evaluating diseased vessels (e.g., arteries) in the human body, for determining the need for treatment, for guiding such interventions and / or using to assess its effectiveness. IVUS mapping uses ultrasound echoes to form a cross-sectional image of the vessel of interest. Typically, an ultrasound transducer on an IVUS catheter transmits ultrasound puls...
