In accordance with the present invention there is provided a catheter for insertion within the human vasculature. The catheter is capable of being irreversibly expanded from a first diameter to a second diameter. The catheter has an elongated shaft with a distal end, a proximal end and a longitudinal axis extending therebetween. The shaft has a lumen extending therethrough. The lumen has a substantially circular cross section of a first diameter. The shaft has two or more stripes of a substantially rigid material and two or more stripes of a substantially expandable and non-resilient material. The rigid stripes disposed between the expandable stripes. The stripes extend between the distal and proximal ends of the shaft.

[ That which is claimed is:] [1.] A catheter for insertion within a patient, said catheter has an inside diameter which is capable of being irreversibly expanded from a first diameter to a second diameter, said catheter comprising:a. an elongated shaft having a distal end, a proximal end and a longitudinal axis extending therebetween, said shaft having a lumen extending therethrough, said lumen having a substantially circular cross-section having a first inside diameter, andb. said shaft comprising two or more arced stripes of a substantially rigid material and two or more arced stripes of a substantially expandable and non-resilient material, said rigid stripes disposed between said expandable stripes, adjacent stripes having ends which are connected to each other, said stripes extending between said distal and proximal ends, said expandable stripes can expand to allow said inside diameter of said shaft to expand, in a substantially uniform manner around a circumference of said shaft, to a second diameter andc. wherein said rigid stripes are made from a material chosen from the group comprising: high density polyethylene rigid polyurethane and polyamides.
