Multi-Stent and Multi-Balloon Apparatus for Treating Bifurcations and Methods of Use

A system for dilating a bifurcated vessel in a patient, the bifurcated vessel having a main branch and a side branch, said system comprising:

• a first delivery catheter having a first elongate shaft with a proximal and a distal end, a proximal expandable member, and a distal expandable member, the proximal and distal expandable members disposed adjacent the distal end of the first elongate shaft,
• wherein the proximal and distal expandable members each have a collapsed configuration and a radially expanded configuration, the collapsed configuration having a profile suitable for advancement through a blood vessel, and the expanded configuration having a larger profile than the collapsed configuration profile, and
• wherein the proximal and distal expandable members are independently expandable of one another;
• and
• a second delivery catheter having a second elongate shaft with a proximal and a distal end, and a second expandable member, the second expandable member disposed adjacent the distal end of the second elongate shaft,
• wherein the second expandable member has a collapsed configuration and a radially expanded configuration, the collapsed configuration having a profile suitable for advancement through a blood vessel, and the expanded configuration having a larger profile than the profile in the collapsed configuration, and
• wherein the second expandable member is independently expandable of the proximal and the distal expandable members.

A system for treating a trifurcated vessel in a patient, the trifurcated vessel having a main branch, a first side branch vessel and a second side branch vessel, said system comprising:

• a first delivery catheter carrying a first stent, the first stent comprising a proximal stent and a distal stent, the first delivery catheter also having a proximal elongate shaft with a proximal and a distal end, and a distal elongate shaft with a proximal and distal end, wherein the proximal elongate shaft comprises a proximal expandable member with the proximal stent disposed thereover, and the distal elongate shaft comprises a distal expandable member with the distal stent disposed thereover, the proximal and distal expandable members disposed adjacent the distal end of the first delivery catheter,
• wherein the proximal and distal expandable members each have a collapsed configuration and a radially expanded configuration, the collapsed configuration having a profile suitable for advancement through a blood vessel, and the expanded configuration having a larger profile than the collapsed configuration profile, and
• wherein the proximal and distal expandable members are independently expandable of one another;
• a second delivery catheter carrying a second stent, the second delivery catheter also having a second elongate shaft with a proximal and a distal end, a second expandable member with the second stent disposed thereover, the second expandable member disposed adjacent the distal end of the second elongate shaft,
• wherein the second expandable member has a collapsed configuration and a radially expanded configuration, the collapsed configuration having a profile suitable for advancement through a blood vessel, and the expanded configuration having a larger profile than the profile in the collapsed configuration, and
• wherein the second expandable member is independently expandable of the proximal and the distal expandable members;
• and
• a third delivery catheter carrying a third stent, the third delivery catheter also having a third elongate shaft with a proximal and a distal end, a third expandable member with the third stent disposed thereover, the third expandable member disposed adjacent the distal end of the third elongate shaft,
• wherein the third expandable member has a collapsed configuration and a radially expanded configuration, the collapsed configuration having a profile suitable for advancement through a blood vessel, and the expanded configuration having a larger profile than the profile in the collapsed configuration, and
• wherein the third expandable member is independently expandable of the second expandable member, and the proximal and the distal expandable members.
