Patent ID: 7892232

Claim:
A medical treatment device for performing a medical procedure in a patient, comprising: an ablation catheter which inserts into a part of a body of the patient to be treated; a visualization device which detects a risk area of the part of the body to be treated and displays the risk area jointly with the ablation catheter and an anatomy of the part of the body; wherein the risk area is extracted from a display of the anatomy and is displayed as a point, line, flat surface, or a volume; a mapping system including a position sensor to measure a position of the risk area and a position of the ablation catheter, to determine a distance between the risk area and the ablation catheter; a communication interface configured to exchange information between the ablation catheter, the visualization device and the mapping system; wherein a degree of danger is determined based on the distance provided by the mapping system between the extracted risk area and the ablation catheter, said degree of danger being continuously determined in real-time based on the distance between the extracted risk area and the ablation catheter being continuously determined in real-time, said degree of danger being inversely proportional to the distance between the extracted risk area and the ablation catheter; and wherein said mapping system is configured to output a warning signal if the degree of danger exceeds a limit value, wherein an intensity of the warning signal is modified depending on the degree of danger.
