摘要:
A guiding sheath has a braided layer for improved deflection characteristics and ring electrodes for electrical sensing, mapping and visualization, wherein lead wires for the ring electrodes are passed through lumened tubing position under the braided layer in a proximal portion of the guiding sheath shaft and above the braided layer in a distal portion of the guiding sheath shaft. Moreover, the hemostatic valve includes an improved friction ring with air vents to reduce the risk of air being introduced into the valve.

A method in accordance with the present invention manufactures a tire with a biaxial monolayer belt component (MBC). The method comprises the steps of: winding a cord continuously about a first drum according to a pre-defined pattern to create a mesh of cords defining a single belt/overlay structure; adjusting the structure to a predetermined position on the first drum by laser lights; applying a tread component to the structure; transferring the structure and tread component to a second drum; applying the structure and tread component to a carcass component on the second drum; reducing pressure of the carcass component by a predetermined amount; and stitching the structure and tread component to the carcass component.

A three-dimensional lattice includes a stabilizing grid having grid warp strands and grid weft strands crossing the grid warp strands. Grid cells are defined by adjacent grid warp strands and adjacent grid weft strands intersecting the adjacent grid warp strands. A projecting net has net warp strands and net weft strands crossing the net warp strands. Each subnet in a plurality of subnets uniquely corresponds to a corresponding grid cell. Each subnet includes a net warp strand portion intersecting both of the grid weft strands that define the corresponding grid cell. Each subnet includes a net weft strand portion intersecting both of the grid warp strands that define the corresponding grid cell. The net warp strand portion and the net weft strand portion of each subnet are spaced from a minimum surface defined by the corresponding grid cell.
