Abstract
The present invention provides an improved core wire for use in a medical catheter. In one aspect, the invention provides a core wire with a shapeable tip and method of manufacturing the same. A core wire previously made superelastic is subject to additional processing to remove its superelasticity thereby allowing the material to be shapeable to aid in advancing the core wire through a blood vessel or other body cavities. In another aspect of the present invention, a method is provided for securing the core wire to the distal end of an elongated catheter tubular body. The tubular body is mechanically crimped onto the core wire to secure the core wire in place. This crimping method has been found to increase the strength of the bond between the core wire and the catheter tube so that greater pull force is required to break the core wire off from the catheter.
