ABSTRACT:
A medical device, such as a catheter in which the catheter has a relatively stiff proximal section and a relatively soft distal section joined by a relatively short transition section in which the materials of the proximal and distal sections are gradually combined in the transition section to form a continuous unbroken tube without abrupt joints. The relatively soft distal section can be provided with a balloon, and the catheter can be provided with multiple passageways. In addition, the catheters can be provided with braiding to provide the finished product with more torqueability and kink resistance.
