Abstract: In a stiffening core for catheters, a plurality of spaced apart wires, which are circular in cross-section are inserted in the surface of a continuous strip of soft plastic material and are embedded by said strip to more than one-half of their cross-sections. Owing to this design, the stiffening core has a stiffness, flexibility and elasticity which can be reproduced within close limits.
