    摘要: The present disclosure relates to valve replacement devices that are foldable for catheter-based deployment to the site of implantation, as well as systems for the delivery of valve prostheses, including prostheses having the special characteristics of the disclosed valve replacement devices. The devices include highly effective adhering mechanisms for secure and enduring precision implantation. The adhering mechanisms may employ a unique sealing mechanism that includes a cuff that expands slowly whereby the device is not secured in place until the completion of the implantation procedure. The implanted device, optionally together with the cuff, prevents perivalvular leaks and incorporate an appropriate leaflet system for reliable functioning in situ.

    摘要: Disclosed herein are devices for assessing mitochondrial function in a living subject comprising a catheter comprising a sheath defining a lumen, a distal end, and a proximal end comprising a light guide for radiating light onto a target within the subject and for receiving a fluorescence signal from the target; a light source, wherein the catheter is adapted for transmitting light from the light source to the light guide; and, a detector for receiving the fluorescence signal from the light guide and for correlating the fluorescence signal to the mitochondrial function of the target. Also disclosed are methods for assessing mitochondrial function in a living subject comprising placing a catheter proximate to a site of interest within the subject; using the catheter to acquire fluorescence signals from cells at the site of interest; and, correlating the fluorescence signals to the mitochondrial function of the cells.

    摘要: A series of rt-3DE images of the mitral valve are quantitatively analyzed so as to enable, for example, prediction of the degree of recurrent ischemic mitral regurgitation (IMR) and comprehensive assessments of leaflet tethering and “tenting” for the entire mitral valve. In accordance with the method, first, the rt-3DE images are registered with symmetric diffeomorphism to obtain information about how the mitral valve deforms over time. Second, the mitral valve is segmented with the level sets or other known segmentation method at each time point in the cardiac cycle with minimal user interaction. Third, the information about mitral valve structure is reduced into a 3D medial model, a compact representation of shape. In other words, a volumetric segmentation of the mitral valve is condensed to a form that is amenable to clinically relevant morphometry.
