ABSTRACT:
Catheter systems comprising a base catheter and a sleeve catheter are modified to have reduced sliding friction therebetween. The sleeve catheter is received over the base catheter, and an inner luminal surface of the sleeve catheter or outer surface of the base catheter is modified to have surface irregularities to reduce sliding friction. Preferably, the surface irregularities are circumferentially spaced-apart V-spaced peaks. Such peaks may be formed by fabricating tubular catheter bodies in an extrusion tool having a mold or die with correspondingly shaped V-shaped grooves therein. Alternatively, the surface irregularities may be imparted using a mold or mandrel which is placed over or in a tubular catheter body, where the desired geometry is transferred by heating the catheter.
