Abstract:
A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.

Claim (Index 13):
A catheter placement device comprising:\n a housing having a front opening, a top opening, and a rear opening, wherein a longitudinal axis extends between the front opening and the rear opening; a needle mating tip connected to the housing at the front opening; a sheath connected to the housing and extending from the rear opening; a guide wire parallel to the longitudinal axis, extending from the sheath through the rear opening and through the front opening to the needle mating tip; a guide wheel assembly inside the housing comprising:\n a first guide wheel having a first guide wheel circumferential surface and a first guide wheel diameter, wherein a portion of the first guide wheel is located outside the top opening of the housing; \n a second guide wheel having a second guide wheel circumferential surface and a second guide wheel diameter, wherein a portion of the second guide wheel is located outside the top opening of the housing; and \n a spacer plate coupled between the first guide wheel and the second guide wheel with a spacer plate diameter smaller than the first guide wheel diameter and the second guide wheel diameter and a spacer plate thickness greater than a guide wire diameter of the guide wire, \n wherein the first guide wheel, the second guide wheel, and the spacer plate are connected and configured so as to share a common rotational axis, rotation rate, and a rotational direction parallel to the longitudinal axis, and \n wherein the guide wire does not contact the first guide wheel or the second guide wheel; \n a drive wheel assembly positioned inside the housing comprising:\n a drive wheel having a drive wheel circumferential surface; and \n a wheel plate having a wheel plate outer circumferential surface, \n wherein the drive wheel and the wheel plate are connected and configured so as to share a common rotational axis, rotation rate, and a rotational direction parallel to the longitudinal axis, \n wherein the drive wheel circumferential surface is engaged with the first guide wheel circumferential surface such that rotating the first guide wheel causes the drive wheel to rotate, and \n wherein the guide wire contacts the wheel plate outer circumferential surface, moves when the wheel plate rotates, and does not contact the drive wheel circumferential surface.
