  • Publication number: 20190099987
    Abstract: Provided is a strand board with improved strength and water resistance. Reduction in productivity is prevented and characteristics of the strand board can be varied as desired while achieving certain strength and water resistance of the strand board. A strand board B is formed by stacking and laminating five strand layers 1 each formed by a large number of strands 5. The strand board B has substantially constant density distribution in the lamination direction of the strand layers 1. Three of the five strand layers 1 of the strand board B are high-density strand layers 1a having a higher density than the other strand layers 1, and the other strand layers 1 are low-density strand layers 1b.

  • Publication number: 20180243551
    Abstract: An electrical stimulation lead includes a body having distal and proximal end portions, a longitudinal length, at least one anchoring lumen, and at least one open slot spaced apart from each end of the lead body. Each anchoring lumen is open at a slot and extends both distally and proximally from the slot. The lead also includes electrodes; terminals; conductors electrically coupling the terminals to the electrodes; and at least one anchoring element at least partially disposed in an anchoring lumen. Each anchoring element includes at least one bent portion biased to extend an extension portion of the anchoring element out of a slot when the anchoring element is in a deployed position and can retract the extension portion into an anchoring lumen when the anchoring element is in a constrained position. The lead further includes an attachment member attached to each anchoring element and disposed proximal to each slot.
