Once formed the balloon is attached to the catheter tubing using hot air, hot dies or laser. Laser bonding creates short, soft and flexible welding-connections of the balloon to the catheter tubing. A CO2 laser provides the most precise heating method to manufacture catheters. Laser energy can be focused to a spot size of less than 0.5mm making short, soft and flexible welding-connections. The end result is precisely reproducible. Applications include proximal/distal balloon bonds, soft tip attachment and other catheter/tube bonding processes.
