Brachytherapy Systems, Intravascular
Definition : Brachytherapy systems designed to deliver radiation (e.g., beta, gamma) to tissue inside the vessels (e.g., coronary or peripheral arteries). These systems typically consist of a radioisotope source delivery unit and a catheter specially designed for application of the intravascular radiation. The most common isotope for gamma irradiation is Iridium-192; for beta irradiation, Phosporous-32, Rhenium-188, Yttrium-90, Strontium-90, and their compounds are used. Intravascular restenosis brachytherapy systems are mainly intended to prevent and/or treat excessive intimal proliferation of tissue that progressively obstructs the arterial lumen (i.e., restenosis) of arteries after angioplasty procedures, frequently inside implanted stents.
