Medical investigation and treatment device's catheter and catheter tip navigating method for treating heart infarct, involves overlaying spatial path on real-time radiological image, and viewing path by displaying overlaid image

摘要

The method involves determining a three-dimensional spatial path (12) through a blockage region (4), and observing a catheter under a real-time radiological image e.g. two-dimensional projection image, of a vessel (2) e.g. coronary artery, of a patient. The catheter is pushed forward in the vessel along the path. Coordinates of the path are registered with the radiological image. The path is overlaid on the radiological image, where the image is generated by an angiographic X-ray through-illumination method. The path is viewed by displaying the overlaid image. An independent claim is also included for a medical investigation and treatment device comprising a catheter.
