Abstract
A method is provided for making a splittable introducer catheter by co-extruding two different polymers of differing solubilities, so that v-shaped strips are formed on each side of the catheter wall which may be easily stripped from the main catheter tube. This leaves an introducer catheter which is easily split along the narrowed v-shaped grooves on diametrically opposite walls of the catheter.
