    摘要: A system for detecting the dimensions and geometry of a native valve annulus for trans-catheter valve implantation includes a compliant balloon and a shaft within the balloon. One or more drive electrodes may be affixed to a surface of the balloon, and one or more sense electrodes may be affixed to the shaft. After insertion of the balloon into the native valve annulus, the drive electrodes may be energized with a predetermined voltage. Using a trained statistical model and the voltages measured at the sense electrodes, initial estimates of the cross-section of the valve annulus may be obtained. The initial estimates may then be provided to an optimization model of the valve annulus to obtain a highly accurate prediction of the cross-section of the valve annulus.

    摘要: A prosthetic device for use in an anatomical orifice or lumen of a patient includes an expandable first stent structure coupled to a valve support structure having at least one leaflet. The stent structure includes a collar provided with at least one groove or opening adapted to engage a tab extending from the valve support structure. Rotation of the stent structure and valve support structure relative to one another assembles the prosthetic valve device. The prosthetic valve device may be used for sutureless treatment of various valvular conditions such as aorta stenosis and mitral valve replacement.
