ABSTRACT:
This invention relates to the preparation of a balloon dilatation catheter which comprises blowing a length of double lumen tubing to produce a double lumen catheter piece having distal and proximal ends and having a first lumen and a second lumen; cutting an opening in the second lumen proximal to the distal end of the catheter piece; inserting a pushing wire having distal and proximal ends into the second lumen through the proximal end of the catheter piece until the distal end of the pushing wire extends distally across the opening; inserting a piece of lubricous tubing into the second lumen through the distal end of the catheter piece; sealing the distal end of the first lumen; heating the distal portion of the catheter piece to cause the distal portion of the second lumen to shrink slightly to cause the lubricous tubing to fixedly engage the distal end of the pushing wire, while the first lumen is pressurized; and heating the remainder of the catheter piece to cause the second lumen to shrink around the pushing wire and the first lumen to shrink to define a balloon.
