Abstract
Methods and devices for providing intravascular local radiation therapy and simultaneous local delivery of a solution of a therapeutic substance are disclosed. The therapeutic substance may be an antiplatelet substance, an antithrombotic substance, a thrombolytic substance, or a mixture thereof, among other possibilities. An exemplary balloon catheter assembly for delivery of the simultaneous radiation and therapeutic substance treatments includes an elongate body with lumen for delivering the solution of the therapeutic substance to a permeable inflation region at a distal end of the body, and a centerable delivery lumen for transporting a radiation source to the treatment site.
