Abstract: A reinforced intravascular catheter adapted for use in performing minimally invasive medical procedures. A catheter, in accordance with the present invention, comprising an inner tubular member having an outer surface, a proximal end, a distal end, and a lumen extending therethrough. The catheter further including a support member overlaying the inner tubular member and conforming to the outer surface thereof, the support member including at least one filament forming a plurality of turns. The support member further including at least one multi-layered portion having a first layer and a plurality of additional layers, each layer comprising a plurality of turns formed by at least one filament, the plurality of additional layers each overlaying at least the first layer. The catheter also including an outer layer overlaying both the support member and the inner tubular member. A method of fabricating a catheter in accordance with the present invention is also disclosed.

Abstract: The present invention relates generally to intravascular catheters for performing medical procedures. An intravascular catheter is disclosed comprising a shaft, the shaft comprising an inner liner having a distal end, a distal tip; a second layer disposed over the inner liner, the second layer extending from the proximal end of the shaft to a distal terminus; a third layer disposed over the second layer; and a fourth layer disposed over the third layer, the fourth layer including a proximal end and a distal end. In addition, a method of manufacturing a catheter according to a preferred embodiment of the invention is disclosed.
