    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.

    摘要: A high performance guide wire with a pressure sensor for measuring blood pressure, may utilize a single electrical lead connected to the guide wire. An integrated circuit, powered by the single electrical connection on the guide wire, may interface with the pressure sensor, and may convert pressure information to an encoded signal. The encoded signal may be detectable in the electrical circuit, and can be used to display a pressure waveform as detected by the pressure sensor. For example, when utilized for percutaneous coronary interventions, such a guide wire can provide high quality blood pressure measurements (e.g., for fractional flow reserve), while also possessing excellent steerability and handling characteristics for navigating tortuous anatomy.
