摘要： A method and apparatus for pre-stressing devices incorporating materials subject to stress softening is disclosed, as well as the resulting device. The method includes fabricating a heart valve with an inflow side and an outflow side. At least a portion of the heart valve includes a material subject to stress softening. The material experiences stress when a pressure differential occurs between the inflow side and the outflow side of the valve. The method includes creating a stress in the material prior to implantation in order to stabilize the stress/strain response of the material prior to implantation.

摘要： A heart valve prosthesis includes a molded body and a plurality of leaflets. Each leaflet includes a free margin having opposite ends and a mid-point. The opposite ends are attached to a peripheral portion of the valve. Each free margin is adjacent each other free margin to form a natural-state non-uniform gap therebetween. The gap has a maximized width adjacent the mid-point of each leaflet. Each free margin is scalloped to form a peak at the opposite ends and a mid-point peak between the opposite ends. Each peak is substantially the same height above the base.

摘要： A valve including a living hinge coupling a leaflet to a valve body. The leaflet can be coupled through the living hinge to the valve body's inner diameter, its outer diameter, or somewhere between the two diameters. Because the living hinge design of the valve is an integrated part, it can be manufactured in a single step.

摘要： A tri-leaflet prosthetic cardiac valve with leaflets having an analytic shape in a selected position. The leaflets are connected to a valve body at attachment curves. The shape of the leaflet is selected from a set of geometries that can be represented mathematically. The attachment curve is selected to improve the durability of the tri-leaflet valve by moving the point of maximum loaded stress along the attachment curve away from the commissures. An inner wall of the valve body is given a non-circular shape near the attachment curve, the shape of the inner wall corresponding to the attachment curve. Also, a method of making a valve by selecting an analytic leaflet shape, selecting an attachment curve to improve durability of the valve by moving the point of maximum loaded stress along the attachment curve away from the commissures, and forming a valve body to support one or more leaflets, the valve body having a non-circular inner wall conforming to the attachment curve.

摘要： A mechanism for steering a photoconductor belt in an electrophotographic imaging system is disclosed. The photoconductor belt is moved about a support roller system of the imaging system to form a continuous transport path. The photoconductor belt tends to deviate from this continuous transport path in a direction substantially perpendicular to the path. The belt steering mechanism includes a support carriage, a steering carriage, a support roller and a belt steering drive assembly. The steering roller is mounted to the steering carriage, and the steering carriage is connected to the support carriage so as to be pivotable about a steering axis. The belt steering drive assembly is operably coupled to the steering carriage to pivotally move the steering carriage about the steering axis. Upon pivotal movement of the steering carriage about the steering axis, the steering roller pivots therewith to move the photoconductor belt in a direction substantially perpendicular to the continuous transport path to reduce deviation of the photoconductor belt from the path.

摘要： A flexible leaflet heart valve includes a base, a peripheral portion and a plurality of leaflets. Each leaflet includes a scalloped free margin having opposite ends and a mid-portion between the opposite ends. The opposite ends are attached to the peripheral portion of the valve at a first height above the base. The mid-portion of each free margin is positioned at a second height above the base, less than the first height. Each free margin is adjacent each other free margin to form a gap therebetween. Each leaflet is of a first thickness and at least a portion of each free margin is of a second thickness, greater than the first thickness. This may include extending the second thickness along the entire free margin between the opposite ends or extending the second thickness only along the mid-portion of the free margin.
