Abstract
A catheter system and method are described for stenting a vessel at a bifurcation or sidebranch of the vessel. The catheter system includes a first balloon catheter, a second balloon catheter and a releasable linking device for holding the first and second balloon catheters arranged in a side-by-side configuration and aligned with one another along a longitudinal axis so that the catheter system can be advanced as a unit. The catheter system is combined with drug eluting technology to prevent restenosis, inflammation and/or thrombosis and/or to promote reendothelialization in the vessel bifurcation. The main vessel stent and/or the sidebranch stent may be coated or impregnated with one or more drugs or bioactive substances. Alternatively or in addition, the first balloon and/or the second balloon may be coated with or include a mechanism for delivering one or more drugs or bioactive substances to the vessel wall.
