Methods and Systems For Ostial Stenting of a Bifurcation

A system for treating a bifurcation, said system comprising:

• a first delivery catheter comprising a first elongate shaft with proximal and distal ends, and a first expandable member adjacent the distal end of the first elongate shaft;
• and
• a second delivery catheter comprising a second elongate shaft with proximal and distal ends, a second expandable member adjacent the distal end of the second elongate shaft, and a radially expandable stent disposed over the second expandable member,
• wherein the stent comprises a sidewall having a side hole therethrough, and wherein the stent has a collapsed configuration suitable for delivery to the bifurcation, and an expanded configuration in which the stent supports a wall of a main branch of the bifurcation and a wall of a side branch of the bifurcation, and
• wherein a first portion of the first elongate shaft is disposed under a proximal portion of the stent, and the first elongate shaft passes through the side hole so that a second portion of the first elongate shaft is disposed over a distal portion of the stent, and wherein the first elongate shaft is axially slidable relative to the second elongate shaft while the stent is in the collapsed configuration.
