Patent attributes
A system (10) includes electromagnetic indicator coils (30) included in surgical devices, examples of surgical devices (20) including guidewires; surgical instruments including dilators, stents, catheters, jejunostomy tubes, and endoscopes; and indicator clips (used for marking a location within patient). An innovative device indicator is attachable to any surgical instrument to convert it to an electromagnetically monitorable instrument. A monitoring unit (50) detects electromagnetic fields from the electromagnetic indicator coils and displays the location and configuration of the electromagnetic indicator coils on a display unit (80). The relative positions and overall configuration of multiple devices—such as guidewires, instruments, and location marker indicator clips—can all be simultaneously electromagnetically monitored with the use of radiology.
