Balloon catheters filled with liquid radioisotopes provide excellent dose homogeneity for
intracoronary radiation therapy but are associated with risk for rupture or leakage. We …

Over the past decade, the introduction of coronary stents brought a quantum improvement in
postangiographic treatment of diseased coronary arteries by providing a scaffolding that …

Background Intravascular brachytherapy is an effective method for inhibiting coronary
restenosis after percutaneous transluminal coronary angioplasty. A new concept for …

Purpose: To determine the efficacy of the use of copper-62, a positron emitter with a half-life
of 9.7 minutes, as an intracoronary brachytherapy (IRBT) source in the prevention of …

Purpose. Optimization of intravascular radiation to reduce stenosis following coronary
angioplasty requires the ability to predict the patterns of radiation dose distribution. This …

Device RADIA-NT'” is manufactured by United States Surgical Corporation, Vascular
Therapies Division,(formerly Progressive Angioplasty Systems). The system comprises a …

Balloon angioplasty is a standard treatment for artherosclerotic coronary artery disease.
However, its clinical value is reduced by a high restenosis rate. A new concept in preventing …

Purpose. Intracoronary gamma or beta radiation from centrally located sources at the time of
overstretch balloon injury inhibits neointimal proliferation. In an effort to deliver …

A substantial body of experimental evidence suggests that local application of radiation at
sites of angioplasty or stent implantation prevents neointima formation. Recent initial clinical …

Background The therapeutic efficacy of percutaneous transluminal coronary angioplasty is
limited by the incidence of restenosis. Intracoronary irradiation has shown to be effective in …
