Abstract
A method of producing a multi-lumen elongate body for a medical device. Unlike known methods requiring a solid core of material inserted into each lumen to maintain patency of the lumens during manufacture, the present method obviates the need for a solid core within one or more minor lumens, which saves cost and production complexity. One or more material overlay and mesh overlay steps may be used to produce the multi-lumen elongate body, but only the main lumen may include a solid core therein during all manufacturing steps. The one or more minor lumens may each be defined by a lumen tube having a sufficient stiffness to withstand external pressure during all manufacturing steps without the need for a solid core within.
