摘要：
Disclosed is a tubular wire coil in which the wire varies in diameter over the length of the coil. The coil can be used to create a coiled reinforcement member for a tubular body, having different physical properties along the length of the body without the need for welds or joints to connect different wire segments. The coil can thus reduce unwanted catheter tip or welded joint stiffness without sacrificing desired proximal stiffness in, for example, a catheter such as a neurovascular catheter.
