INTRODUCER ASSEMBLY EXTENSION AND METHOD OF USE
First Claim
1. An introducer assembly comprising:
- an introducer with a distal segment sized to be received through a puncture site and into a passageway within a patient, and a proximal segment with a fitting having a male luer;
an extension that includes a flexible tube extending between a first fitting with a female luer and a second fitting with a male luer; and
the female luer of the extension being connected to the male luer of the introducer.

Abstract
An introducer set includes an introducer and dilator along with an extension in a sealed sterile peal open package. The extension is available for use during procedures where the puncture access site to the patient is close enough to the site to be treated in the patient that the physician'"'"'s hands and/or head may be positioned in the fluroscopic area while the physician is attempting to maneuver a wire guide to a desired location. When the extension is attached to the introducer, the physician may perform a procedure, such as an antigrade stick in the lower leg of a patient, while maintaining their hands and head outside of the fluroscopic area while direct radiation is being supplied and the wire guide is being maneuvered to a desired treatment location. After the wire guide has been properly positioned and the radiation has been terminated, the extension may be disconnected from the introducer and the remaining portions of the procedure (guide catheter insertion, balloon catheter insertion and dilation, etc.) may proceed in a known manner. The extension need only be in the range of ten to thirty centimeters to allow the physician to work a safe distance from the fluroscopic area undergoing direct radiation.

8. A method of positioning a wire guide at a desired location in a passageway of a patient, comprising the steps of:
-
positioning a distal segment of an introducer through a puncture site into the passageway of the patient while a proximal segment extends outside the patient; connecting an extension to the proximal segment of the introducer; injecting radiopaque dye into the passageway; positioning the desired location and at least a portion of the introducer within a fluoroscopic area while a proximal end of the extension is outside the fluoroscopic area; and maneuvering a wire guide, through the extension and introducer into the passageway and toward the desired location, from outside the fluoroscopic area while passing radiation through the fluoroscopic area. - View Dependent Claims (9, 10, 11, 12, 13)

14. An introducer set comprising:
-
an introducer; a dilator mated to the introducer; an extension that includes a flexible tube extending between a first end and a second end, and a first fitting with a male luer attached to the first end, and a second fitting with a female luer attached to the second end, and a length between the male luer and the female luer being in a range of ten to thirty centimeters; and the introducer, the dilator and the extension being sterile and sealed in a peal-open package. - View Dependent Claims (15, 16, 17, 18, 19, 20)
