Problems solved by technology

Conventional support members have many disadvantages
For example, the fabrication techniques available for metals (e.g. milling, welding, etc.) limit the geometries of support members that can be produced
Similarly, steel cannot reflow with polymers, nor can it effectively scatter or attenuate ultrasonic waves
Therefore, the structure of conventional support members may limit the mechanical and / or acoustic performance of IVUS devices

Abstract

Intravascular imaging probes including a multi-material support member or base, and related devices, systems, and methods are provided. According to one embodiment, an intraluminal ultrasound imaging catheter includes: a flexible elongate member configured to be positioned within a body lumen of a patient; a support member coupled to the distal portion of the flexible elongate member; and an ultrasonic scanner assembly positioned about the support member. The support member includes a hollow inner member including a first material, and a first annular member positioned around a perimeter of the hollow inner member at a proximal portion of the hollow inner member. A first annular member extends radially outward from the hollow inner member and includes a second material different from the first material.

Description

technical field [0001] The present disclosure relates generally to the structural arrangement of intravascular ultrasound devices, and more particularly, to intravascular ultrasound devices having support members formed from various materials to provide structural support and other mechanical properties to the device. Background technique [0002] Intravascular ultrasound (IVUS) imaging is widely used as a diagnostic tool in cardiac interventions to assess diseased blood vessels (eg, arteries) in the human body to determine the need for treatment, guide intervention, and / or assess its effectiveness. An IVUS device including one or more ultrasound transducers is introduced into the blood vessel and directed to the area to be imaged. The transducer emits ultrasonic energy to form an image of the blood vessel of interest. Ultrasound is reflected by discontinuities caused by tissue structures (eg, various layers of blood vessel walls), red blood cells, and other features of int...
