Abstract:
1. A balloon catheter for dilation of a body lumen, 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 portion and a proximal portion, 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, wherein at least a length of an outer surface of the balloon comprises a working diameter adapted to dilate the body lumen, the length extending between the proximal portion and the distal portion; and a plurality of dilation wires, each having a proximal and distal end, extending along a portion of the working diameter of the balloon, each dilation wire being encapsulated in a sheath, each dilation wire being completely circumscribed in a radial direction, and each dilation wire being longitudinally constrained within the sheath, the sheath axially extending past the respective proximal and distal ends of each dilation wire and being pressed down over the respective proximal and distal ends of each dilation wire and being fused to encapsulate each dilation wire; wherein the sheath is attached to the outer surface of the balloon and the sheath forms a radially extending cutting edge.
