Abstract: Methods and systems for attaching a radiopaque marker to a prosthetic heart valve to indicate a location of a commissure of the prosthetic heart valve are disclosed. As one example, a prosthetic heart valve includes a frame including a plurality of struts forming a plurality of cells of the frame arranged between an inflow end and an outflow end of the frame, a plurality of leaflets arranged within the frame, and at least one commissure comprising an attachment member arranged across a selected cell of the plurality of cells of the frame and commissure tabs of two adjacent leaflets coupled to the attachment member. The valve further includes a radiopaque marker arranged on the attachment member of the commissure within the selected cell.

Abstract: A grilling oven for foodstuffs comprising an oven casing having rows of apertures/gaps in the lower section uniformly facing various directions. The grilling oven has three layers disposed apart from each other by the supporting bars attached to the plates/grids in the bottom-to-the-top order. The plates/grids include the plate/grid containing the burning materials, the plate/grid is used to scatter and increase the heat and prevent the fat and nutritious juices from overflowing to the burning materials, the plate/grid containing the foodstuff to be grilled. These plates/grids and supporting bars are removable from the oven casing since the diameters of the plates/grids are smaller than the internal diameter of the oven wall. The oven cover has various rows of ventilation holes disposed uniformly throughout the cover to adjust and guide—distribute the heat in contact with the foodstuff more uniformly so that the foodstuff will not be burnt out.

Abstract: The useful solution mentions the naturally pure pot for planting, comprises a pot (1), the lower half of which has locating ribs (2) lying vertically, prominent inward and equally distancing from each other; two rows of draining holes (3) lying alternately in vertical direction and lower than the upper end of locating ribs (2); a supporting board (4) with holes placed in the pot, rest on the upper end of locating ribs, prominent as cornice on the inside of the pot (1); a cloth covers the supporting board (4) and is fastened and let down. To water the earth in the pot from the above until the water overflows the draining holes (3). To sow seed or to plant in the pot (1).
