An elongated guide (10) for use in medical procedures is provided, the guide having a flexible metal core (12) and a forward portion comprising an elongated, helically wound wire coil (20) providing a flexible tip. A flexible safety wire (12) extends forwardly within the coil (20) and terminates forwardly in an integral, enlarged diameter portion defining a plug (14) carried adjacent the forward end of the coil (20), the plug (14) having a diameter at least approximately equal to the inner diameter of the coil (20) at its forward end and substantially filling the lumen of the coil. A bonding agent (22) such as a polymeric resin, solder or the like is employed to adhere the plug (14) to the coil (20). |
