    Abstract: The invention is a delivery catheter, e.g., a guide catheter, having expandable elements proximate to the distal end of the catheter. Catheters of the invention are easier to place in proximity to an ostium, thereby increasing the efficiency of contrast delivery while reducing the risk of ischemia due to blocked blood supply. The invention additionally directs the flow of a fluid from the catheter, resulting in better performance with less fluid. For example, a catheter of the invention can be used to produce improved fluoroscopic images with less overall contrast. This improvement also decreases the length of time for a procedure, i.e., because of a need to re-contrast.

    Abstract: The invention provides methods and systems for correcting translational distortion in a medical image of a lumen of a biological structure. The method facilitates vessel visualization in intravascular images (e.g. IVUS, OCT) used to evaluate the cardiovascular health of a patient. Using the methods and systems described herein it is simpler for a provider to evaluate vascular imaging data, which is typically distorted due to cardiac vessel-catheter motion while the image was acquired.

    Abstract: The invention provides systems and methods that provide a plurality of different displays (i.e., data formats) corresponding to intravascular imaging, such as obtained with intravascular ultrasound (IVUS) or optical coherence tomography (OCT). The plurality of displays may be provided to a single user, e.g., a cardiovascular surgeon, or the displays may be divided between multiple users, e.g., a surgeon, a surgical tech, and a radiologist.

    Abstract: This invention relates generally to the detection of objects, such as stents, within intraluminal images using principal component analysis and/or regional covariance descriptors. In certain aspects, a training set of pre-defined intraluminal images known to contain an object is generated. The principal components of the training set can be calculated in order to form an object space. An unknown input intraluminal image can be obtained and projected onto the object space. From the projection, the object can be detected within the input intraluminal image. In another embodiment, a covariance matrix is formed for each pre-defined intraluminal image known to contain an object. An unknown input intraluminal image is obtained and a covariance matrix is computed for the input intraluminal image. The covariances of the input image and each image of the training set are compared in order to detect the presence of the object within the input intraluminal image.
