Abstract
Disclosed is a delivery catheter adapted for delivery of a dose of radiation to a vessel wall. A radiation source is enlargeable from a first, reduced cross-sectional profile to a second, enlarged cross-sectional profile by unwinding around a central core. Following delivery of a radiation dose to the vessel wall, the source is reduced in profile by wrapping around the core and removed from the treatment site.
