Abstract
A method of making a cannula includes providing a plurality of polymer reservoirs with each reservoir containing a polymer material and providing a nozzle mounted within each reservoir of the plurality of reservoirs. The method further includes one or more of preheating the mandrel, generating a polymer material wave from each nozzle, rotating the mandrel over the nozzles to form an initial coat on the mandrel, curing the initial coat, depositing a reinforcing material around a selected section of the mandrel and ensuring that the reinforcing material is held in place at the selected section of the mandrel. The method further includes rotating each section of the mandrel over a selected nozzle to form an additional coat, curing the additional coat, and removing the tubular structure from the mandrel.
