Abstract:
1. A balloon catheter for dilation of a vessel wall, comprising: a shaft having a distal end and a proximal end; a balloon mounted on the distal end of the shaft, the balloon having a distal tapered portion and a proximal tapered portion, wherein at least a length of an outer surface of the balloon comprises a working diameter adapted to dilate the vessel wall, the shaft having an inflation lumen extending therethrough in fluid communication with an interior region of the balloon, the balloon thereby being expandable between a deflated state and an inflated state; and a plurality of separate dilation elements each comprising a coil and a single dilation wire, the dilation wire having a proximal end and a distal end, one of the proximal and the distal ends of the dilation wire affixed to the coil at a joint where a diameter of the one of the proximal and the distal ends extends a predetermined distance into the coil, the coil extending in a first direction from at least the working diameter of the balloon to the shaft and the coil affixed to the shaft, the coil extending along and substantially in contact with the proximal or distal tapered portion of the balloon and the other one of the proximal and distal ends of each of the dilation wires affixed to the shaft.
