摘要

Balloon catheter for angioplasty characterized by a catheter shaft having an inflatable balloon at its distal end and a restriction that limits the expansion of the inflatable balloon, said restriction structure one unexpanded configuration before inflation and an expanded configuration it is smaller than a size unrestricted ball so that the structure limits the inflation of the balloon along a plurality of lines of channel intersection, which carries at least on part of its surface of paclitaxel or a preparation of free paclitaxel polymer and propyl gallate in an amount of 3 to 100% by weight of said at least one antioxidant relative to 100% by weight of paclitaxel, wherein the balls of scoring or cutting as medical devices are excluded .
