ABSTRACT:
A rapid exchange balloon catheter having a proximal end and a distal end, said catheter comprising: a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, said distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, said guide wire lumen extending from a proximal side port to a distal end opening. To reduce the resistance to kinking, the metal body comprises a transitional region having reduced stiffness at the position of bonding to the plastics distal end portion compared to a more proximal position along the metal body.
