Abstract
An elongated guide for use in medical procedures is provided, the guide having a flexible metal core and a forward portion comprising an elongated, helically wound wire coil providing a flexible tip. A flexible safety wire extends forwardly within the coil and terminates forwardly in an integral, enlarged diameter portion defining a plug carried adjacent the forward end of the coil, the plug having a diameter at least approximately equal to the inner diameter of the coil at its forward end and substantially filling the lumen of the coil. A bonding agent such as a polymeric resin, solder or the like is employed to adhere the plug to the coil.
