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.
Claims21
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 having at least two adjacent strands fused together;
- wherein each of the first and second layers is heat-treated such that the change in outer diameter of the second layer between its free state and its constrained state is less than 10 percent.

A cable comprising:
- a first layer of wire helically wound to define a lumen having a lumen diameter;
- a second layer of wire helically wound over the first layer, the wire in the first and second layers being a single, unbroken piece;
- a first end segment configured with a plurality of strands that are fused together;
- a second end segment configured with a plurality of strands that are fused together;
- and
- wherein the cable is characterized by the first and second layers having been heated between 20 and 40 minutes at a temperature of between 260 and 700 degrees Celsius.

A method of forming a cable comprising:
- winding a first layer of wire over a mandrel thereby defining a lumen having a lumen diameter;
- winding a second layer of wire over the first layer;
- fusing a plurality of strands of wire together in a first end segment of the second layer such that at least two adjacent strands are fused together;
- and
- heating the first and second layers between 20 and 40 minutes at a temperature of between 260 and 700 degrees Celsius.
