摘要： A heart valve and method of making the same, the valve regulating the flow of fluid in a body passage. The valve comprises a substantially circular body having an outer ring portion and at least two interior flap portions. Each flap portion is pivotally secured to the ring along an axis represented by chords of the ring and being flexible to pivot in response to the flow of fluid in the passage. Means are located on each flap portion which are adapted to engage the wall of the ring portion to limit movement of the flap in one direction. The flaps are cooperatively shaped to close the interior of said body when they are pivoted in the one direction to their limit.

摘要： A MIXTURE OF ETHYLENEGLYCOL MONOMETHACRYLATE WITH A LITTLE ETHYLENEGLYCOL DIMETHYACRYLATE IS POLYMERIZED IN A MOLD ROTATING ABOUT AN AXIS PERPENDICULAR TO A SPHERICALLY CONCAVE MOLD FACE TO FORM A SHAPE-RETAINING HYDROPHILIC POLYMER LAYER. A VERY THIN LAYER OF OPAQUE MATTER IS DEPOSITED ON THE EXPOSED POLYMER FACE AND COVERED WITH A SECOND LAYER OF THE SAME POLYMER. THE OPAQUE MATERIAL MAY SIMULATE THE IRIS, PUPIL, AND/OR SCLERA OF AN EYE WHEN THE LAMINAR PRODUCT IS ULTIMATELY SWELLED BY CONTACT WITH PHYSIOLOGICAL SALINE SOLUTION PRIOR TO USE AS SOFT CONTACT LENS OR AS PART OF AN ARTIFICAL EYE.

摘要： The invention relates to an implant for directed infusion of active substances, which implant consists of a hollow body with one wall formed by a thin permeable membrane and with a chamber inside the body, which chamber is connected at least by one channel with the outside space. This enables practically unidirectional diffusion of the active substance directly to the affected tissue and to maintain or arbitrarily change the concentration and type of the active agent.
