  • Patent number: 9551814
    Abstract: In a method for manufacturing a structure of curable material, a first structure from a first curable material is molded and cured on a substrate, and a second structure of a second curable material is molded and cured on a first surface of the first structure facing away from the substrate, so that at the first surface of the first structure a boundary surface forms between the first and second structures so that the first structure is not covered by the second structure in a passage area. A solvent is introduced into the passage area to dissolve the first curable material of the first structure so that a cavity forms between the second structure and the first surface of the substrate. After curing, the first curable material is soluble and the second curable material is insoluble for the solvent. An optical component and an optical layer stack are made of curable material.

  • Patent number: 9539614
    Abstract: A medical electrical lead body having an outer surface and including at least one lumen having an inner surface treated with a silane surface modifying agent to form a three-dimensional, densely cross-linked lubricious coating over at least a portion of the inner surface of the lumen. The outer surface of the lead body also may be similarly treated. The lubricious silane coating may reduce the coefficient of friction of the coated surface of the lead body by as much as 80% when compared to an uncoated surface. A reduction in the coefficient of friction may enhance the stringing efficiency of a conductor through the lead body lumen and may enhance its abrasion resistance.
