ABSTRACT:
A catheter and method of making a catheter are disclosed in which the catheter is highly flexible and yet resistant to crushing and kinking. The catheter is made by applying rings of hard polymer material along the tubular shaft as the catheter is manufactured. The catheter thus has a plurality of hard polymer rings formed at spaced locations along its length, and soft segments between the hard polymer rings that allow the catheter to remain very flexible. The hard polymer rings improve the radial strength of the catheter and make the catheter resistant to crushing and kinking.
