Abstract

A catheter insertion device for inserting a catheter into a body of a patient includes a retractable needle for establishing access to a subcutaneous vessel of the patient and a manually extensible guidewire for guiding the initially attached catheter into the vessel. In one embodiment, the catheter insertion device includes a housing, a hollow needle retractably extending from the housing, a catheter initially disposed on a portion of the needle, a guidewire including a portion initially disposed within the needle, a guidewire advancement feature configured to selectively advance a distal end of the guidewire distally past a distal end of the needle, and a needle retention component configured to selectively enable retraction of the needle into the housing. The needle retention component is configured to be actuated by the guidewire advancement feature. In one embodiment, one-handed operation of the device is possible.

Claims

1. A catheter insertion device, comprising:

a housing;

a hollow needle retractably extending from the housing;

a catheter initially disposed on a portion of the needle, at least a distal portion of the catheter initially positioned distal of the housing;

a guidewire, at least a portion of the guidewire initially disposed within the needle;

a guidewire advancement feature configured to selectively advance a distal end of the guidewire distally past a distal end of the needle; and

a needle retention component configured to selectively enable retraction of the needle into the housing, the needle retention component configured to be actuated by the guidewire advancement feature.

2. The catheter insertion device as defined in claim 1, wherein the guidewire advancement feature includes a guidewire advancement handle slidably included with the housing.

3. The catheter insertion device as defined in claim 1, wherein the needle retention component includes a spring configured to retract the needle.

4. The catheter insertion device as defined in claim 1, wherein the guidewire includes a guidewire hub attached to a proximal end of the guidewire, the guidewire hub removably attached to a guidewire advancement handle.

5. The catheter insertion device as defined in claim 4, wherein the guidewire hub separates from the guidewire advancement handle when the guidewire advancement handle is distally advanced a predetermined amount.

6. The catheter insertion device as defined in claim 5, wherein the needle is attached to a needle hub, the needle hub including a flash chamber.

7. The catheter insertion device as defined in claim 6, wherein the guidewire hub impinges on the flash chamber so as to separate from the guidewire advancement handle when the guidewire advancement handle is distally advanced the predetermined amount.

8. The catheter insertion device as defined in claim 7, wherein retraction of the needle causes retraction of the flash chamber, the flash chamber causing retraction of the guidewire hub.

9. The catheter insertion device as defined in claim 1, wherein the needle retention component is configured to be actuated by full distal advancement of the guidewire advancement feature.

10. The catheter insertion device as defined in claim 9, wherein the needle retention component is movable by the full distal advancement of the guidewire advancement feature from a first position wherein the needle retention component engages a portion of a needle hub to prevent the retraction of the needle to a second position wherein the needle retention component enables the retraction of the needle into the housing.

11. The catheter insertion device as defined in claim 10, wherein the needle retention component includes a plate disposed in a distal portion of the housing, the plate movable between the first and second positions.

12. The catheter insertion device as defined in claim 11, wherein the guidewire advancement feature includes a first angled surface, wherein the plate includes a second angled surface, and wherein engagement between the first and second angled surfaces causes the plate to move from the first position to the second position.

13. The catheter insertion device as defined in claim 12, wherein the plate defines a keyhole including a semicircular portion and a circular portion, wherein the portion of the needle hub is disposed in the semicircular portion when the plate is in the first position and wherein the portion of the needle hub moves to the circular portion when the plate moves from the first position to the second position.

14. A catheter insertion device, comprising:

a housing;

a hollow needle extending from the housing;

a catheter assembly initially disposed on a portion of the needle and removably connected to a portion of the catheter insertion device;

a guidewire, at least a portion of the guidewire initially disposed within the needle;

a guidewire advancement feature configured to selectively advance a distal end of the guidewire distally past a distal end of the needle; and

a needle retention component configured to selectively enable retraction of the needle into the housing, the needle retention component configured to retract the needle upon detachment of the catheter assembly from the catheter insertion device, the needle retention component configured to be actuated by the guidewire advancement feature.

15. The catheter insertion device as defined in claim 14, wherein the needle retention component is actuated to retract the needle when the catheter assembly is rotatably detached from the housing of the catheter insertion device.

16. The catheter insertion device as defined in claim 14, wherein the needle retention component is operably connected to a needle hub, the needle hub attached to the needle.

17. The catheter insertion device as defined in claim 16, wherein the needle retention component includes first and second retention arms that extend from a portion of the needle hub, the first and second retention arms each including a distal portion that extends beyond a distal end of the housing.

18. The catheter insertion device as defined in claim 17, wherein a distal end of each of the first and second retention arms includes a hook, the hook configured to engage threads of a hub of the catheter assembly to removably attach the catheter assembly to the housing.

19. The catheter insertion device as defined in claim 18, wherein the catheter assembly is detached from the hooks of the first and second arms when the hub of the catheter assembly is rotated by a user, the rotation of the hub of the catheter assembly causing the threads of the hub of the catheter assembly to detach from the hooks.

20. The catheter insertion device as defined in claim 19, wherein the hub of the catheter assembly includes a finger tab to enable the user to rotate the hub.

21. The catheter insertion device as defined in claim 20, wherein a profile of the finger tab includes at least one of a square profile, a round profile, and an elongated profile.

22. The catheter insertion device as defined in claim 14, wherein the catheter insertion device is configured for one-handed use by a user.

23. A method of making a catheter insertion device, the method comprising:

removably disposing a catheter assembly on a portion of a needle, the needle extending from a housing;

disposing a distal portion of a guidewire in a lumen defined by the needle, the guidewire having a proximal portion aligned with a longitudinal axis of the needle;

movably including a guidewire advancement feature with the housing so as to enable selective movement of a distal end of the guidewire distally past a distal end of the needle; and

including with the needle a needle retention component configured to enable retraction of the needle into the housing, the needle retraction component configured to be actuated by full distal movement of the guidewire advancement feature with respect to the housing.
