摘要：
Medical devices that are visible by magnetic resonance imaging (MRI), and optionally, other imaging techniques, are described. In some embodiments, a medical device adapted for insertion into the body includes an elongated shaft and an electrically conductive path extending spirally about a portion of the shaft. The conductive path is capable of being connected to a current source. The medical device can further include one or more contrast agents (such as MRI contrast agents, radiopaque materials, and/or ultrasound visible materials), which can be arranged in a predetermined manner.
