Abstract
A low profile balloon-on-a-wire catheter having a flexible elongate tubular member with proximal and distal extremities and with a lumen extending from the proximal extremity to the distal extremity. An inflatable balloon is mounted on the distal extremity of the flexible elongate tubular member. Communication is established between the lumen and the interior of the inflatable balloon. An inflation fitting is removably secured to the proximal extremity of the flexible elongate tubular member for supplying an inflation fluid to the lumen for inflating and deflating the balloon. The inflation fitting when removed provides a proximal extremity on the catheter which is free of obstructions so that another balloon catheter can be advanced over the proximal extremity of the flexible elongate tubular member.
