Intravenous catheter insertion device and method of use
First Claim
1. A catheter insertion device, comprising:
- a housing having an interior space;
an access needle that is slideable with respect to the interior space, said access needle having a lumen therethrough;
a guide wire moveably received in the lumen of the access needle, wherein the guide wire has a safety tip which straightens when the tip is drawn proximally into the needle lumen and assumes a planar coil configuration when the safety tip is advanced distally from the distal end of the needle lumen, wherein the planar coil of the guide wire is coplanar with a straight portion of the guide wire proximal to the coil; and
a handle attached to the guide wire and axially slideable on the housing, wherein movement of the handle is limited so that at least a portion of the guide wire always remains in the interior space while the safety tip of the guide wire can move in and out of the needle.

Abstract
A catheter insertion device with a housing and an interior space. An access needle and a guide wire supported by and moveable relative to the access needle. A restraining element attached to a handle to limit the motion of the guide wire relative to the access needle. A catheter insertion device with a housing and an interior space. An access needle and a guide wire channel attached to the access needle. A guide wire supported by the guide wire channel. A handle attached to the guide wire to move the guide wire relative to the guide wire support channel. A method of introducing a catheter into a vessel by inserting a guide wire substantially contained within a housing into a vessel. Next, advance a catheter over the guide wire and into the vessel.
