Abstract
An insertion device includes a needle assembly having a distal end with a needle tip and a needle connector, a handle portion releasably connectable to the needle assembly, the handle portion including a handle connector portion that is configured to mate with the needle connector. A guidewire tube is connected to the handle portion, and is coiled to store a guidewire. The guidewire tube has an uncoiled length that is longer than its coiled circumference. The coil of the guidewire tube and the handle portion generally extend along a common plane. An axis through a center of the coil of the guidewire tube is substantially perpendicular to the common plane.
