Catheters, Vascular, Brachytherapy
Definition : Vascular catheters designed to deliver radiation to a predetermined area inside a vessel and/or into a stent previously inserted into the vessel. These devices typically consist of double-lumen catheters that center the radiation source (e.g., a metallic wire, liquid containers) within a closed lumen, while allowing side and distal perfusion through the other lumen. Vascular catheters for brachytherapy procedures are mostly intended to prevent and/or treat restenosis in arteries after angioplastic procedures, including restenosis in the inner part of stents (i.e., in-stent restenosis); they are used as a component of intravascular brachytherapy systems that also include a unit for delivery and retrieval of the radiation source.
