Differentially expandable stent

A system for stenting a bifurcation, comprising:

• a stent comprising:
• a proximal region, a distal region, an intermediate region disposed between the proximal region and the distal region, and a longitudinal axis extending between the proximal region and the distal regions;
• wherein the proximal region comprises one or more interconnected closed rings,
• wherein each closed ring comprises a plurality of interconnected undulating struts having a plurality of peaks and valleys,
• the proximal region further comprising a proximal connector element coupled between adjacent closed rings,
• wherein the distal region comprises one or more interconnected closed rings,
• wherein each closed ring in the distal region comprises a plurality of interconnected undulating struts having a plurality of peaks and valleys,
• the distal region further comprising a distal connector element coupled between adjacent closed rings,
• wherein the proximal region has a proximal strut cell density and a proximal collapsed configuration and a proximal expanded configuration,
• wherein the distal region has a distal strut cell density and distal collapsed configuration and a distal expanded configuration,
• wherein the proximal strut cell density is different than the distal strut cell density, and
• a delivery catheter, wherein the stent is carried by the delivery catheter.

A method of manufacturing a differentially expandable stent, comprising:

• providing a tubular member;
• cutting the tubular member using a pattern file to form a stent structure comprising a proximal region, a distal region, and an intermediate region disposed between the proximal and distal regions;
• wherein the proximal region comprises one or more closed rings, each closed ring comprising a plurality of interconnected undulating struts having a plurality of peaks and valleys;
• wherein the distal region comprises one or more closed rings, each closed ring comprising a plurality of interconnected undulating struts having a plurality of peaks and valleys;
• wherein the proximal region has a proximal strut cell density and the distal region has a distal strut cell density, the proximal strut cell density being different than the distal strut cell density.
