Abstract
A method for manufacturing a catheter member having at least one lumen is disclosed herein. The method includes, winding a sacrificial coil over a mandrel in a first direction and winding a reinforcement coil over the sacrificial coil in a second direction. A polymer is then laminated over the sacrificial coil and the reinforcement coil. After the polymer is laminated, the mandrel is removed and the sacrificial coil is removed to thereby form the catheter member having the lumen.
