Try Small Parts Inc
They have dozens of sizes:
Part no R-GWXX-050 fits inside 30 Ga hyperdermic tubing
60 inches cost $3.64 with no minimum order, and modest shipping charges
The last three digits of the part number give the wire diameter in thousands
of an inch, from -050 to -650
Small parts also has an amazing catalogue of tubing, meshes, bearings..etc.
Another source is Plastic Products, who make pre-built infusion cannulas.
However, I've found them to be more expensive, and had problems getting
delivery in less than a month.
