摘要： A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.

摘要： A balloon wrapping apparatus is disclosed by which a balloon can be accurately positioned and inserted in relation to a pleating section. The balloon wrapping apparatus for wrapping a balloon provided at a distal portion of an elongated shaft includes: a pleating section that forms the balloon with wing shapes; a folding section that folds the wing shapes formed in the balloon along a circumferential direction; a support base that supports a portion other than the distal portion of the shaft, and that makes the distal portion of the shaft insertable into the pleating section and the folding section; and a core metal member to be inserted in the shaft. The core metal member is inserted in the shaft from a distal end position of the balloon to at least the proximal side of a proximal end position of the balloon.
