  • SYSTEM FOR INTRODUCING AN INTRALUMINAL ENDOPROSTHESIS AND METHOD FOR MANUFACTURING SUCH A SYSTEM
    Publication number: 20100076539
    Abstract: A system for introducing an intraluminal endoprosthesis (30), preferably a stent, into a body cavity. The system consists of the intraluminal endoprosthesis (30) and a catheter with a balloon (10), the balloon (10) having at least one wing (12) in an undilated condition. The system has at least one active pharmaceutical substance (20) arranged at least partially beneath the at least one wing (12) of the balloon (10) in the undilated condition. The intraluminal endoprosthesis (30) is fixedly arranged on the folded balloon (10) such that the endoprosthesis surrounds the balloon at least partially and protects the at least one active pharmaceutical substance (20) from being washed out and rubbed off. Further disclosed is a method for manufacturing such a system.
