Method of and apparatus for navigating medical devices in body lumens by a guide wire with a magnetic tip
摘要：
A guide wire combined with a catheter or medical device for moving through a body lumen to a desired position in the body with the aid of an applied magnetic field. The guide wire is provided with a magnet on its distal end that can be oriented or oriented and moved by the application of a magnetic field to the magnet. A catheter or other medical device can be advanced over the guide wire. Once the medical device is in its desired position, the magnet can be withdrawn through the lumen of the catheter. Alternatively, a guide wire with a magnet on its distal end can be docked at the distal end of a catheter or medical device and can be oriented, or oriented and moved by the application of a magnetic field.
摘要（中）：

导丝与导管或医疗装置组合，用于借助于施加的磁场将体腔移动到身体中的期望位置。 引导线在其远端设置有可以通过向磁体施加磁场而定向或定向和移动的磁体。 导管或其他医疗装置可以在导丝上前进。 一旦医疗装置处于其期望的位置，磁体可以通过导管的内腔抽出。 或者，在其远端具有磁体的导丝线可以对接在导管或医疗装置的远端，并且可以通过施加磁场而定向或定向和移动。
