Abstract:
1. A device for applying endovascular brachytherapy, comprising: a brachytherapy catheter having a catheter tip; a flexible tube-shaped catheter jacket of the brachytherapy catheter; an OCT catheter simultaneously used with the brachytherapy catheter that is arranged within the flexible tube-shaped catheter jacket of the brachytherapy catheter and positioned on a target position at the same time as the brachytherapy catheter, the brachytherapy and OCT catheters forming one integrated catheter unit; a radiation emitter attached to the catheter tip of the brachytherapy catheter and adapted to prevent restenosis after plaque removal from a vascular wall by emitting radioactive radiation; an OCT image system connected to the OCT catheter; and a control device having a user interface for controlling the device, the user interface including an input device for entering radiation parameters of the radiator, wherein the radiation parameters of the radiation emitter include parameters of activation data and half-life period, wherein the OCT catheter comprises at least one rotating OCT signaling line arranged within the flexible tube-shaped catheter jacket of the brachytherapy catheter, the rotating OCT signaling line connected to a rotating OCT sensor arranged within a circumferential ring-shaped window, the rotating OCT sensor being a rotating mirror, wherein the OCT sensor is arranged within the brachytherapy catheter and adjacent to the radiation emitter, wherein the radiation emitter is a split emitter comprising at least two emitter parts and the OCT sensor is arranged between a first and a second emitter part, wherein the OCT image system is adapted to fade isocentric radiation lines into an OCT image of the OCT image system, and wherein the OCT image system is adapted to measure a duration of applied radiation.
