Abstract
Abstract The dilatation balloon catheter assembly is adapted to be inserted into a blood vessel and comprises a single catheter body having a distal end, a distal end portion, and a proximal end, and a double wall dilatation balloon assembly including an inner inflatable balloon wall and an outer balloon wall with a space therebetween, the balloon walls each having a distal end and a proximal end, and each balloon wall surrounding and being connected at both its distal and proximal ends directly or indirectly to the distal end portion of the single catheter body.
