Abstract
Official abstract text for this publication.
A medical device system includes a needle having a tip including a permanent magnet, and a magnet sensing device including a plurality of sensors configured to detect the magnetic field of the permanent magnet. The magnet sensing device is operable to localize a position of the permanent magnet relative to the magnet sensing device and to indicate a path of the needle on a display.
First claim
Opening claim text (preview).
What is claimed is: 1. A medical device system, comprising: a needle having a tip including a permanent magnet; and a magnet sensing device including a plurality of sensors configured to detect a magnetic field of the permanent magnet, the magnet sensing device operable to localize a position of the permanent magnet relative to the magnet sensing device and to indicate a path of the needle on a display. 2. The system according to claim 1 , wherein the path is a three-dimensional projection. 3. The system according to claim 1 , wherein the magnet sensing device includes an audible indicator operable to provide a representation of the position of the permanent magnet relative to the magnet sensing device. 4. The system according to claim 1 , further comprising a light emitting element coupled to the magnet sensing device. 5. The system according to claim 4 , wherein the light emitting element is configured to provide visible light with sufficient brightness to penetrate tissue of a body such that the light is visible from a location inside the body. 6. The system according to claim 4 , wherein the magnet sensing device and the light emitting element are in physically separable housings. 7. The system according to claim 4 , wherein the light emitting element is positioned on a face of the magnet sensing device, the light emitting element operable to confirm the position of the permanent magnet relative to the magnet sensing device.
