摘要：
The invention provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes an elongate shaft having a distal region and a coil disposed along the distal region. The coil is formed from a winding member having a first filar region and a second filar region. The winding member has a first cross-sectional diameter along the first filar region, a second cross-sectional diameter different from the first cross-sectional diameter along the second filar region, a first centroid at a first position along the first filar region and a second centroid at a second position along the second filar region. The first centroid and the second centroid are axially-aligned.
