Abstract

Embodiments of the present disclosure relate to intravascular imaging devices with low reverberation housings and related systems and methods. In some particular embodiments, devices of the present disclosure include a transducer housing that includes a slot on the backside of the ultrasound transducer to deflect ultrasound signals away from the ultrasound transducer. For example, in some embodiments, there is provided an intravascular imaging device comprising: a catheter body; a drive cable extending through a lumen of the catheter body; a housing; and an ultrasonic transducer mounted within the housing, wherein the housing includes a slot on the back side of the ultrasonic transducer shaped to deflect ultrasonic signals away from the ultrasonic transducer transducer. Methods of making such devices and systems are also provided.

Description

Technical field [0001] The present disclosure generally relates to a vascular device, and more particularly to an imaging catheter having a low allen housing for improving imaging fidelity. Background technique [0002] Invascular ultrasound (IVUS) imaging is widely used as diagnostic tools in interventional cardiology to assess the vessels of lesions, such as arteries within the human body to determine whether it is needed to guide intervention, and / or assess their Effectiveness. IVUS imaging techniques use ultrasonic echo to form a cross-sectional image of the blood vessel. Typically, ultrasonic transducers on the IVUS catheter transmit ultrasonic echoes that are both ultrasonic pulses and reflection. Ultrasonic waves are easily passed through most tissues and blood, but they are reflected in partially reflected by the tissue structure (such as the layers of the blood vessel wall), red blood cells, and other interests of interest. IVUS imaging system, which is connected to th...
