DEVICE FOR APPLYING ACTIVE INGREDIENTS TO THE WALL OF A BODY VESSEL

摘要

The invention relates to a device for applying active ingredients to the wall of a body vessel for treating the vessel wall, comprising a catheter, a guide element and a distal element arranged on the guide element. The distal element is equipped with a soft, atraumatic surface that can be adapted to the vessel wall and carries the active ingredient and strives for a greater diameter after exiting the catheter than the maximum diameter of the vessel in the segment of the body vessel to be treated, wherein the greater diameter is effected by elastic forces in the distal element.
