Means and method for stenting bifurcated vessels

摘要

A system for placing a stent into the side branch of an arterial bifurcation. The system includes: (i) An inflatable balloon (15') located at a distal portion of a stent delivery system (16'), the stent delivery system having an outer shaft (11) with a longitudinal length, the outer shaft having a distal end that is fixedly attached to the proximal end of the balloon. (ii) A pre-deployed side branch stent (14) mounted coaxially onto the balloon for placement into the side branch of an arterial bifurcation, the stent having a proximal end and a distal end. (iii) A guide wire (6); and (iv) A main guide wire tube (12) having a proximal end and a distal end and having an interior lumen (19) that allows the stent delivery system to be moved slideably over the guide wire, the main guide wire tube being fixedly attached to the balloon at a location that is in close proximity to the proximal end of the stent.
