    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: A device and method for exchanging guide catheters over a guide wire, while maintaining the position of the guide wire within a patient. One guide catheter exchange device includes an elongate shaft and a distally tapering tube disposed at the distal end of the shaft. The tube includes a guide wire lumen and a controlled resistance washer having an aperture disposed in line with the guide wire lumen. One controlled resistance washer is formed of a resilient material and has an aperture with a central hole and four radial slits. The radial slits form control flaps which have, in a relaxed state, a minimum inside dimension less than the outside diameter of the guide wire to be received. While receiving a guide wire, the control flaps are in a flexed state and exert a static frictional force on the guide wire. The exerted frictional force inhibits longitudinal movement of the guide wire. Guide wire movement could otherwise be result from frictional forces caused by proximally retracting the guide catheter over the guide wire.

    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.
