A medical device includes an elongated body having a proximal end and a distal end and a braided tubular body extending coaxially with the elongated body between the proximal and distal ends. The braided tubular body includes multiple cables extending helically in opposing directions in an interwoven manner. Each cable includes multiple, electrically conductive filars. In some examples, each filar includes an electrically insulating coating or layer.

Medical device with braided tubular body

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.
