<p num="1"><br/><br/><br/>A catheter system and method are described for stenting a vessel at a <br/>bifurcation or sidebranch of the vessel. The catheter system comprises: a <br/>first balloon catheter (102) having a shaft with a proximal end and a distal <br/>end and a first inflatable balloon (130) mounted on the shaft proximate to the <br/>distal end; and a second balloon catheter (104) having a shaft (134) with a <br/>proximal end and a distal end, and a second inflatable balloon mounted on the <br/>shaft proximate to the distal end, and an elongated flexible extension tube <br/>(135) extending distally from the second inflatable balloon; and is <br/>characterized in that when the catheter system is in an undeployed state with <br/>the first inflatable balloon in a deflated condition, at least a portion of <br/>the first inflatable balloon is wrapped around a portion of the flexible <br/>extension tube.<br/>
