Abstract
A cable includes a first layer of wire helically wound to define a lumen having a lumen diameter. A second layer of wire is helically wound over the first layer. A first end segment of the second layer is configured with a plurality of strands that are fused together. A second end segment of the second layer is configured with a plurality of strands that are fused together.
Claims28
A cable comprising:
- A first layer of wire helically wound to define an inner lumen having a lumen diameter;
- a second layer of wire helically wound over the first layer;
- and
- a first end segment configured with a plurality of strands of wire that are fused together;
- wherein the first end segment is fused along a helical path such that adjacent strands of wire within the first end segment are fused in multiple locations along helices of each strand of wire.
