Abstract

A device is disclosed for providing an indication as to the relative position of a vessel or artery opening thereby facilitating the choice of which several closure techniques to use. A disclosed device includes an outer tube and a collapsible foot slidably disposed within a distal end of the outer tube. The device may further include one or more threaded suture needles, a biodegradable plug or other wound closing device that is connected to another shaft. The collapsed or folded foot is pushed distally out of the tube and through the opening in the vessel whereupon the foot expands. Pulling the expanded foot in the proximal direction provides an indication as to the orientation of the opening in the vessel, which assists in determining the type of closing procedure to be carried out.

First claim

What is claimed is:

1. A device for determining an orientation of an opening in a vessel, the device comprising:
an outer tube;
a collapsible foot slidably disposed within a distal end of the outer tube; and
the foot being connected to a shaft, the shaft passing through the tube and exiting a proximal end thereof, the foot being pushable distally out of the tube and through the opening in the vessel whereupon the foot expands, and
wherein pulling on the expanded foot in the proximal direction against the vessel provides an indication as to whether the opening in the vessel is in a top stick position, a left stick position or a right stick position.

2. The device of claim 1 , wherein the foot has a shape selected from the group consisting of heart-shaped, triangular-shaped, star-shaped, oval-shaped and pear-shaped.

3. The device of claim 1 , wherein the foot and shaft are made from a single piece of wire.

4. The device of claim 3 , wherein the foot may be re-collapsed after bleeding through the opening is controlled and the foot and shaft may be removed.

5. The device of claim 3 , wherein the wire comprises a first proximal end connected to a first shaft section connected to the foot that is connected to a second shaft section terminating at a second proximal end.

6. The device of claim 1 , wherein the shaft is connected to an indicator bar with indicia marked thereon for indicating a first position of the foot when the opening is disposed on a left side of the vessel, a second position of the foot when the opening is disposed on a top of the vessel and a third position of the foot when the opening is disposed on a right side of the vessel.

7. The device of claim 6 , wherein the tube has a window disposed toward a proximal end thereof and the indicator bar is positioned in alignment with the window so the indicia can be seen through the window.

8. The device of claim 1 , wherein the tube accommodates a suturing mechanism.

9. The device of claim 8 , wherein the suturing mechanism comprises a plurality of threaded hook needles.

10. The device of claim 1 , wherein the tube accommodates a plug for closing the opening.

11. The device of claim 10 , wherein the tube further accommodates a shaft for moving the plug distally toward the opening or for holding the plug in position as the tube is withdrawn.

12. A device for determining an orientation of an opening in a vessel and for closing the vessel, the device comprising:
an outer tube;
a collapsible foot slidably disposed within a distal end of the outer tube, the foot being connected to a first shaft, the first shaft passing through the tube and exiting a proximal end thereof; and
a threaded suture needle, the needle being connected to a second shaft, the foot being pushable distally out of the tube and through the opening in the vessel whereupon the foot expands, and
wherein pulling on the expanded foot in the proximal direction against the vessel provides an indication as to whether the opening in the vessel is in a top stick position, a left stick position or a right stick position.

13. The device of claim 12 , wherein the foot is heart shaped.

14. The device of claim 12 , wherein the foot and first shaft are made from a single piece of wire.

15. The device of claim 14 , wherein the foot may re-collapsed after bleeding through the opening is controlled and the foot and first shaft may be removed.

16. The device of claim 15 , wherein the wire comprises a first proximal end connected to a first shaft section connected to the foot that is connected to a second shaft section terminating at a second proximal end.

17. The device of claim 12 ,
wherein the first shaft is connected to an indicator bar with indicia marked thereon for indicating a first position of the foot when the opening is disposed on a left side of the vessel, a second position of the foot when the opening is disposed on a top of the vessel and a third position of the foot when the opening is disposed on a right side of the vessel; and
wherein the tube has a window disposed toward a proximal end thereof and the indicator bar is positioned in alignment with the window so the indicia can be seen through the window.

18. A device for determining an orientation of an opening in a vessel and for closing the vessel, the device comprising:
an outer tube;
a collapsible foot slidably disposed within a distal end of the outer tube, the foot being connected to a first shaft, the first shaft passing through the tube and exiting a proximal end thereof; and
a biodegradable plug connected to a second shaft, wherein the foot may be pushed distally out of the tube and through the opening in the vessel whereupon the foot expands, and
wherein pulling on the expanded foot in the proximal direction provides an indication as to whether the opening in the vessel is in a top stick position, a left stick position or a right stick position.

19. The device of claim 18 , wherein the foot is heart shaped.

20. The device of claim 18 , wherein the foot and first shaft are made from a single piece of wire.

21. The device of claim 20 , wherein the foot may be re-collapsed after bleeding through the opening is controlled and the foot and shaft may be removed.

22. The device of claim 20 , wherein the wire comprises a first proximal end connected to a first shaft section connected to the foot that is connected to a second shaft section terminating at a second proximal end.

23. The device of claim 18 , wherein the first shaft is connected to an indicator bar with indicia marked thereon for indicating a first position of the foot when the opening is disposed on a left side of the vessel, a second position of the foot when the opening is disposed on a top of the vessel and a third position of the foot when the opening is disposed on a right side of the vessel, and wherein the tube has a window disposed toward a proximal end thereof and the indicator bar is positioned in alignment with the window so the indicia can be seen through the window.
