Patent ID: 8882713

Claim:
A vascular access system comprising: a needle having a proximal end, a sharpened distal end, a tubular body, and a central lumen therethrough; an over-the-needle guidewire configured to fit over the outside diameter of the needle, the guidewire comprising a proximal section and a distal section, wherein the proximal section comprises a first cross-sectional profile in the proximal section, wherein the distal section comprises an outer tubular sidewall, a skive in the outer tubular sidewall configured for passage of the needle therethrough, the guidewire having the first cross-sectional profile proximally and a second cross-sectional profile distally, and a transition zone between the first cross-sectional profile and the second cross-sectional profile, wherein the second cross-sectional profile is smaller than the first cross-sectional profile; and a luer connector operably connected to the needle having at least one input port fluidly connected to the central lumen of the needle, and a guidewire lumen not fluidly connected to the central lumen of the needle, the guidewire lumen configured to slidably house the guidewire therethrough, the guidewire lumen having a longitudinal axis that forms an acute angle with respect to a longitudinal axis of the luer connector.
