A flexible, fluid flow tubing is configured to be kink resistant, and amedical device is configured with such kinkresistant tubing. The tubing has a length L, an inside radius r and an outsideradius R, wherein L/R >；= 34.8, and wherein R/r >；= 1.5. Adistal portion of the tubing is received in a channel of a hollow needle. Thehollow needle is slideable axially relative to the tubing,to selectively slide off of the distal portion of the tubing. An insertion setsystem includes a base on which the tubing is secured, andan inserter having the needle and moveably received by the base. The baseincludes a fluid passage transverse to the axial dimensionof the distal end portion of the tubing.
