摘要： 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. Another means includes a restraining sleeve applied over the free ends.

摘要： 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.

摘要： The present invention relates generally to catheters for performing medical procedures including percutaneous transluminal coronary angioplasty. More particularly, the present invention relates to guide catheters, diagnostic catheters and balloon catheters with an improved shaft design. In a preferred embodiment, the present invention includes a catheter shaft comprising an elongate support member having an outer surface, the elongate support member preferably defining a lubricious liner; a first layer disposed over the lubricious liner, a second layer disposed over the first layer, a third layer disposed over the second layer, a fourth layer disposed over the third layer, and a fifth layer disposed over the fourth layer. In preferred embodiments, the first and third layers comprise an ultraviolet-curable epoxy which is cured to desired degrees at select axial locations on the shaft to provide desired stiffness.
