Abstract
A method of manufacturing a catheter includes positioning a resilient tube in a vacuum tube. An outer periphery of the resilient tube is sealed to the vacuum tube so a vacuum region can be formed therebetween. A dimension of a channel of the resilient tube is adjustable in response to adjusting the pressure of the atmosphere of the vacuum region. The dimension of the channel is adjusted so that a reinforcement member can be positioned therein.
