A tubing assembly for manufacture for a catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding said inner member, and a support member mounted between the tubular members to provide rigidity to the flexible catheter. The support member comprises a high tensile strength wire braid, and in the preferred embodiment comprises a stainless steel wire braid which has been tempered or hardened. This higher tensile strength affords significantly greater kink resistance to the flexible catheter. One wire braid has a tensile strength in the range of 300 to 425 kpsi and a braid density of approximately 40 pic. The high tensile strength wire braid has the disadvantage of tending to flare out at its free ends. Therefore, means are provided for preventing the flaring of the wire braid during manufacture of the tubing assembly. One means includes adhesive applied over the free ends.

An intravascular guide catheter includes a main shaft member, a bond member, an intermediate shaft member and a terminal shaft member. The main shaft has a proximal end and a mating distal end. The bond ring includes a mating proximal end, which is joined to the mating distal end of the main shaft member, and a mating distal end. The intermediate shaft member includes a mating proximal end, which is joined to the mating distal end of the bond member, and a mating distal end. The terminal shaft member includes a mating proximal end, which is joined to the mating distal end of the intermediate member, and a distal end. The main and intermediate shaft members have wire braiding reinforcing layers. The material of the intermediate shaft member has a greater hardness than the material of the terminal shaft member and a lower hardness than the material of the main shaft member.

A guiding catheter for use in coronary angioplasty and other cardiovascular interventions which incorporates a transition element in the shaft of the device. The transition element which has a different flexibility than the sections immediately proximal and distal to it, creates a zone in the catheter shaft which is either more or less flexible than the rest of the shaft. The transition element allows a portion of the shaft to be made more rigid or more flexible, without changing the flexibility of the other portions of the shaft. The transition element also allows for a differential flexibility to be added to the catheter shaft.

An intravascular flexible catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding the inner tubular member, and a metallic support member situated between the tubular members to provide rigidity to the flexible catheter. In the preferred embodiment the support member comprises a stainless steel wire braid which has been tempered or hardened to give it a significantly higher tensile strength than the prior art annealing process. This higher tensile strength affords significantly greater kink resistance to the flexible catheter as the lumen size is increased and the wall thickness is decreased.
