Patent application number | Description | Published |
20090163405 | Angiogenic peptides and uses thereof - A peptide comprising an amino acid sequence as set forth in SEQ ID NO: 2, 4, 6, 8, 10 or 12 is provided. The peptide being at least 6 and no more than 50 amino acid residues in length. Also provided are therapeutic applications using such peptides. | 06-25-2009 |
20100081933 | TREATING WEAKENED VESSEL WALL SUCH AS VULNERABLE PLAQUE OR ANEURYSMS - Described is a method of stabilizing blood vessel wall abnormality. The method includes ultrasonically heating at least a portion of the blood vessel wall having the abnormality; monitoring a parameter related to a property of at least a portion of the heated portion of the blood vessel wall; and stopping the heating when the monitored parameter changes by a predetermined factor or after the monitored parameter changes in a slow enough rate. The slow enough rate may be, for instance, a predetermined fraction of a maximal rate change observed during heating. | 04-01-2010 |
20140128844 | DEPLOYMENT MECHANISM FOR BODY VESSEL INSERTION DEVICES - An aspect of some embodiments of the invention relates to a microcatheter comprising a deployment element disposed about around at least a portion of an exterior of a distal end of the microcatheter, the deployment element configured for repeatedly expanding and collapsing, the distal end arranged to allow forward or reverse axial displacement while the deployment element maintains a position, the deployment element arranged for positioning the microcatheter distal end approximately in the middle of a vessel. A method of traversing tortuous vessels using the microcatheter, in accordance with an exemplary embodiment of the invention, is also described. | 05-08-2014 |
20140200867 | VASCULAR FLOW ASSESSMENT - A method for vascular assessment is disclosed. The method comprises receiving a plurality of 2D angiographic images of a portion of a vasculature of a subject, and processing the images to produce a stenotic model over the vasculature, the stenotic model having measurements of the vasculature at one or more locations along vessels of the vasculature. The method further comprises obtaining a flow characteristic of the stenotic model, and calculating an index indicative of vascular function, based, at least in part, on the flow characteristic in the stenotic model. | 07-17-2014 |
20140218397 | METHOD AND APPARATUS FOR PROVIDING VIRTUAL DEVICE PLANNING - A method, apparatus and computer program product are therefore provided to enable virtual planning and selection of devices. In this regard, the method, apparatus, and computer program product may receive an image, where the image includes a set of image scale values. The image scale values may map the image size to real world units of measure. The image scale values may be used to scale the size of a model of a device, such that the model of the device may be superimposed on the image. The model of the device may be manipulated to view the relationship of the device model to the image to assist with selection of the proper device for a procedure. In this manner, a practitioner may visualize the device in the same scale as the image, so that the practitioner may be assured that the size and scale of the device is accurate. | 08-07-2014 |
20150201948 | RADIAL ARTERY DEVICE - According to an aspect of some embodiments of the present invention there is provided a vessel pressure control device configured for selectively applying pressure to a radial artery, the device comprising: a sensor configured to sense one or more parameters associated with blood flow through a portion of the radial artery; a pressure application element adapted to apply variable amounts of pressure to the portion of the radial artery; and a controller configured to apply logic and generate a signal to control the pressure application element in response to the one or more measured parameters, the signal controlling the pressure application element to modify or maintain the applied pressure so that at least some blood flow is maintained through the radial artery portion in an amount sufficient to reduce or prevent radial artery occlusion, and so that the applied pressure is sufficient to prevent bleeding from the portion. | 07-23-2015 |
20150335304 | DIAGNOSTICALLY USEFUL RESULTS IN REAL TIME - Method for real-time vascular modeling and assessment. Modeling, in some embodiments, comprises receiving a plurality of 2-D angiographic images of a portion of a vasculature of a subject, and processing the images to automatically detect 2-D features, for example, paths along vascular extents, which are projected into 3-D to determine homologous features among blood vessels and construct 3-D vascular extents and determine other vascular characteristics. Assessment, in some embodiments, comprises processing models selectively different from one another to produce one or more vascular indexes which indicate a diagnostic preference, for example, to perform a medical intervention such as a stent implantation. Speed is achieved, for example, by the method being optimized for determining the effects of a medical intervention. In some embodiments, results are produced quickly enough to allow use of the method to perform PCI within the same catheterization used to perform diagnostic imaging. | 11-26-2015 |
20150339847 | CREATING A VASCULAR TREE MODEL - A method for vascular modeling is disclosed. The method, in some embodiments, comprises receiving a plurality of 2-D angiographic images of a portion of a vasculature of a subject, and processing the images to automatically detect 2-D features, for example, paths along vascular extents, which are projected into 3-D to determine homologous features among blood vessels. In some embodiments, projection and/or image registration is iteratively altered to improve feature position matching. Based on 3-D vascular extents and their registration to 2-D images, additional features such as vascular width are optionally determined and added to the model. | 11-26-2015 |
