Abstract
A torquable guiding catheter for use in mapping the wall of a heart of the patient with a mapping catheter having a distal extremity and a mapping device carried by the distal extremity and carrying a plurality of electrodes for engaging the wall of the heart. The basket-like device is movable between expanded and contracted positions and in a contracted position having an outside diameter no greater than a predetermined diameter. The torquable guiding catheter comprises a flexible elongate braided shaft assembly having proximal and distal extremities and having a smooth outer surface and also having a smooth inner surface defining a lumen extending from the proximal extremity to the distal extremity. The flexible elongate braided shaft assembly includes a braid formed of flat metal ribbon extending from the proximal extremity to the distal extremity and having plastic covering the braid having a Shore hardness durometer ranging from 55D to 75D. The surface defining the lumen is formed by a liner of a lubricious material adhered to the plastic encapsulating the braid and has a diameter at least as great as the predetermined diameter of the mapping device in a contracted position.
