System and methods for treating a bifurcation with a fully crimped stent

A system for treating a bifurcated vessel, said system comprising:

• a first delivery catheter comprising a first elongate shaft with a proximal end and a distal end, a first expandable member adjacent the distal end of the first elongate shaft, and a first radially expandable stent disposed over the first expandable member, wherein the first stent comprises a sidewall having a side hole therethrough, and
• wherein the first stent has a crimped configuration and an expanded configuration, in the crimped configuration the first stent is coupled with the first expandable member, and in the expanded configuration the first stent supports a vessel wall;
• and
• a second delivery catheter comprising a second elongate shaft with a proximal end and a distal end, a second expandable member adjacent the distal end of the second elongate shaft,
• wherein a portion of the second delivery catheter is disposed under the proximal portion of the first radially expandable stent, and
• wherein a portion of the second delivery catheter is slidably disposed in the side hole of the first radially expandable stent, and
• wherein in the crimped configuration, the first stent is crimped over the first and second delivery catheters such that the first stent remains attached to the first and the second delivery catheters during advancement of the delivery catheters through a blood vessel.
