Intraluminal catheter with a composite shaft
First Claim
1. An intravascular catheter for performing diagnostic or therapeutic procedures within a patient'"'"'s blood vessel comprising a catheter shaft having an inner lumen extending therein and a wall defining the inner lumen which is formed of a polymeric matrix and braided polymeric strands therein with a plurality of reinforcing metallic ribbons separate from the braided polymeric strands within the wall of the composite shaft.

Abstract
A composite tubular element for intravascular catheters, such as fixed-wire dilatation catheters and guiding and angiographic catheters, which is formed by braiding strands formed from an intimate mixture of polymeric matrix materials, such as fibers and powders, having a relatively low melting point and high strength reinforcing fibers having a relatively high melting point into a tubular element, heating the braided tubular element to melt the low melting point matrix materials and flow around the reinforcing fibers to form a matrix. A thermoplastic jacket or coating may then be extruded or otherwise applied to the exterior of the braided tubular element.
