a balloon catheter that may include a catheter shaft having a proximal end and a distal end , the catheter shaft having a core having an outer surface , the core extending to the distal end of the catheter shaft , the catheter shaft having a tubular member disposed about the core , the tubular member having an inner surface and an outer surface , and an inflation lumen between the tubular member inner surface and the tubular member outer surface , and an inflatable member having a proximal cone , a distal cone and a central section therebetween , the central section having proximal and distal ends , the proximal and distal cones defining an inflation cavity , the inflatable member further comprising a proximal waist affixing the proximal cone to the outer surface of the tubular member and a distal waist affixing the distal cone to the outer surface of the core , wherein the inflatable member is configured such that the distance along the longitudinal axis between the distal end of the central section and the distal waist is less than the distance between the proximal end of the central section and the proximal waist , wherein the inflation lumen is fluidly connected to the inflation cavity .
