Abstract
The present invention provides a device, system and method for uniformly delivering a radiation dose over the surface area of a stenosed vessel during or after a percutaneous transluminal angioplasty procedure. A helical balloon is inflated in the region to be treated, preferably in contact with the vessel wall, and a radiation source is drawn through the helical coils of the balloon to provide a uniform dosage. Alternatively, the helical balloon is disposed within a cylindrical balloon and the helical balloon containing a radiation source with at least one coil is drawn through the cylindrical balloon.
