Embodiment Construction

[0029] The present invention provides systems and methods for detecting endoleaks based on a combination of intraluminal images and intravascular functional parameters such as flow. In particular, the present invention is a system comprising an intravascular diagnostic imaging probe with expanded imaging capabilities and a processor for processing image data and causing display of related information, such as flow, to provide flow visualization. In one embodiment, the present invention includes an intravascular ultrasound (IVUS) device comprising an imaging probe having one or more ultrasound transducers, wherein the imaging probe can be introduced into a blood vessel and Manipulated to the site for placement of the stent graft. Once located, the imaging probe can collect suitable data which can then be used to discern the presence of an endoleak. For example, ultrasound transducers are configured to acquire more than one form of data related to blood vessels and stents place...

Abstract

The present invention is a system comprising an intravascular imaging probe with expanded imaging capabilities and a processor for processing image data and causing relevant information such as flow to be displayed. The system is configured such that the image data is processed and reconfigured in a user-friendly format (e.g., color-coded) to provide flow details, including placement sites of stent-grafts within the lumen associated with EVAR or TEVAR procedures Automatic or semi-automatic detection of endoleaks at or near the The system is further configured to provide identification of the type of endoleak present.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to US Provisional Patent Application Serial No. 61 / 925939, filed January 10, 2014, the contents of which are incorporated by reference. technical field [0003] The present invention relates generally to assessing cardiovascular health, and more particularly to methods for detecting endoleaks associated with aneurysm repair using a system with visualization and flow detection capabilities. Background technique [0004] An abdominal aortic aneurysm (AAA) is an abnormal swelling of the lower portion of the aorta that runs through the abdominal region. The aorta is the main blood vessel that carries blood from the heart to the rest of the body. The walls of the aorta are elastic, which allows the vessel to be filled with blood under high pressure. An aneurysm occurs when the walls of an artery become weakened and swell. Many factors can contribute to the weakening of ...
