Embodiment Construction

[0029] The present invention is a co-registration system configured to co-register data sets captured by multiple intravascular and extravascular modalities and for detection of endoleaks associated with endovascular aneurysm repair. By way of overview, a system typically includes an imaging catheter that has expanded imaging capabilities and is configured to acquire more than one form of image data related to a vessel and a stent placed therein, including intraluminal structural data and vascular inflow data. The system is configured to generate an intravascular image including at least structural and flow data to provide flow visualization of the blood vessel. The system also includes one or more sensors for capturing functional measurements of the blood vessel, such as flow or pressure. The system also includes an external imaging modality for capturing external image data (eg, radiological images) of the vessel.

Abstract

The invention provides co-registration systems and methods for detecting endoleaks associated with aneurysm repair. The system includes an imaging device having expanded imaging capabilities and configured to capture and provide image data and flow visualization of a vessel based on the image data. The system further includes one or more sensors for capturing functional parameters of the vessel, such as flow or pressure. The system further includes an external imaging modality for capturing external image data of the vessel, such as, for example, a radiological image. The co-registration system is configured to co-register sets of data captured by a plurality of intra- and extraluminal modalities and provide a composite map (3- or multi not dimensional) of the vessel including automatically detected areas of interest, particularly during an EVAR or TEVAR procedure.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to U.S. Provisional Patent Application Serial No. 61 / 925939, filed January 10, 2014, and U.S. Provisional Patent Application Serial No. 61 / 925996, filed January 10, 2014, by The contents of each of these applications are incorporated by reference. technical field [0003] The present invention relates generally to assessing cardiovascular health, and more particularly to methods for detecting endovascular disease associated with aneurysm repair based on co-registered datasets from a number of different endoluminal and extraluminal modalities. Leaky method. 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 vess...
