Guidewire positioning tool

A guidewire positioning tool, comprising:

• a sheath having a bore extending axially through a length of the sheath, the bore having a slot extending radially from the bore, the bore and slot configured to receive a guidewire;
• a collet portion extending laterally from the sheath, the collet having collet arms and interstitial spaces, a bore extending axially through a length of the collet portion, the bore having a slot extending radially from the bore, the bore and slot configured to receive a guidewire, the collet arms having threads located on the exterior of the collet arms;
• a clamp nut positioned over the collet portion and configured to threadably engage the threads;
• and
• a retainer rotatably attached to an end of the sheath opposite from the collet portion, the retainer having a bore extending axially through a length of the retainer, the bore having a slot extending radially from the bore, the bore and slot configured to receive a guidewire,
• where the sheath includes a radially positioned aperture to allow for fluid communication between the exterior of the sheath and the bore of the sheath.
