Abstract
A system and method for manufacturing a plurality of cannulas configured to facilitate the delivery of medicament to a user having internal coils can include providing spacers along portions of a mandrel between the coils. Spacers prevent shifting of the coils both during assembly on the mandrel and during the extrusion process, which will ensure sufficient material extending beyond the coil for creation of the tapered distal end for the cannula. Use of spacers also provides a more uniform outer wall.

A method of manufacturing a plurality of cannulas configured to facilitate delivery of medicament to a user, comprising:
- arranging a plurality of coils on a mandrel;
- providing a spacer on the mandrel between each of the coils to form an assembly having alternating coils and spacers along the mandrel;
- processing the assembly through an extrusion device to form an outer tube around the assembly;
- cutting the processed assembly adjacent both ends of each coil to create a plurality of cannula sections;
- and
- forming a cannula configured to facilitate delivery of medicament from each cannula section.
