Abstract

A catheter insertion device includes a housing, a needle, a catheter, and a guide wire. The needle has a proximal end positioned in the housing and a distal end extending beyond a distal end of the housing. The catheter is positioned coaxially over the needle, and includes a flexible tube and a catheter hub on a proximal end of the flexible tube. A proximal portion of the flexible tube and the catheter hub are positioned in the housing. the guide wire has a proximal end positioned in the housing and a distal end positioned in a lumen of the needle. The catheter insertion device also includes a handle coupled to the catheter, wherein movement of the handle relative to the housing moves the catheter hub from a position in the housing to a position outside of the housing.

Claims

1. A catheter insertion device, comprising:

a housing;

a needle having a proximal end positioned in the housing and a distal end extending beyond a distal end of the housing;

a catheter positioned coaxially over the needle, the catheter comprising a flexible tube and a catheter hub on a proximal end of the flexible tube, wherein a proximal portion of the flexible tube and the catheter hub are positioned in the housing;

a guide wire having a proximal end positioned in the housing and a distal end positioned in a lumen of the needle; and

a handle coupled to the catheter, wherein movement of the handle relative to the housing moves the catheter hub from a position in the housing to a position outside of the housing.

2. The catheter insertion device according to claim 1, further comprising a guide wire advancement member, wherein movement of the guide wire advancement member moves the guide wire relative to the needle.

3. The catheter insertion device according to claim 2, wherein the guide wire advancement member includes a guide wire carrier associated with the guide wire in the housing.

4. The catheter insertion device according to claim 2, wherein movement of the guide wire advancement member is initiated by a user.

5. The catheter insertion device according to claim 1, wherein the guide wire distal end comprises a coiled tip.

6. The catheter insertion device according to claim 1, wherein a distal end of the flexible tube extends beyond a distal end of the housing prior to movement of the catheter hub to the position outside of the housing.

7. The catheter insertion device according to claim 1, wherein movement of the handle is initiated by a user.

8. The catheter insertion device according to claim 1, further comprising a seal at a proximal end of the catheter hub.
