Abstract
A method of manufacturing tubing suitable for use as a component of a medical device, such as a catheter body, and the real-time adjustment of characteristics of the tubing as it passes from one reel to another reel during manufacture. Thus, a length of tubing is manufactured that includes a plurality of segments of different flexibilities and the length of tubing is then cut into a plurality of sub-lengths of tubing that are suitable for use as a component of a medical device. In one embodiment, a method of manufacturing a length of catheter tubing comprises: extruding a base layer; overlaying a braided layer on the base layer; overlaying a sub-jacket layer over the braided layer; overlaying an outer jacket on the jacket sub-layer; and heating at least a portion the jacket sub-layer to change a characteristic of the length of catheter tubing.
