ABSTRACT:
An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire. The apparatus includes a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire. The connecting device is configured for mating with the steering device to form an integral unit. The invention further includes a method of inserting a guidewire in a body and connecting the guidewire to an extension guidewire. The method includes the steps of: providing an integral guidewire holder and tool for connecting a guidewire to an extension guidewire; gripping the guidewire with the integral guidewire holder; inserting the guidewire into a body lumen; displacing the integral guidewire holder and tool relative to the guidewire so that the proximal end of the guidewire is located in a slot of the integral guidewire holder and tool; inserting an extension guidewire into the slot of the integral guidewire holder and tool; and connecting the guidewire to the extension guidewire. The method further includes the step of aligning the guidewire and extension guidewire in the slot prior to the connecting step.
