Abstract

This invention relates to apparatus and methods for use in sealing a vascular puncture site and to apparatus and methods for properly locating and deploying a sealing device. The locating apparatus comprises a lumen which extends from an opening in the distal region of the apparatus but located proximally of the sealing device, which lumen extends to another opening in the proximal region of the device. When the distal opening is in communication with blood in a blood vessel, blood flow through the lumen and out of the proximal opening signifies such location to the user. When the sealing device is withdrawn such that the sealing device is deployed such that it blocks the blood flow into the distal port, the user will know the location of the sealing device. In a preferred embodiment, the sealing device is then withdrawn proximally a predetermined distance to assure that no part of the sealing device extends into the blood vessel lumen. The sealing device is then detached from the delivery device.

Claims

1. A device for sealing a puncture in a wall of a body lumen comprising:

an elongate member having a distal port, a proximal port, and a passage connecting the distal and proximal ports,

an obturator extending through at least a portion of the elongate member, the obturator having a distal portion adapted to selectively prevent movement of a sealing member in a proximal direction when the elongate member is withdrawn proximally to release the sealing member to seal the puncture of the wall of the body lumen, and

a guidewire extending through the elongate member, the guidewire having a transversely disposed portion at a distal region.

2. The device of claim 1, wherein the sealing member is located distally of the distal portion of the obturator.

3. The device of claim 1, further comprising

a guidewire tube extending through a lumen in the elongate member, wherein the guidewire is retained within the guidewire tube.

4. The device of claim 1, further comprising

an actuator coupled to the elongate member, the actuator adapted to facilitate movement of the elongate member relative to the obturator.

5. The device of claim 1, wherein the transversely disposed portion at the distal region of the guidewire engages the wall of the body lumen to indicate the position of the sealing member.

6. The device of claim 1, wherein the elongated member is a tubular structure and the distal port is a hole in the side of the tubular structure.

7. A device for sealing a puncture in a wall of a body lumen comprising:

an elongate member having a distal opening, a distal port, a proximal port, and a passage connecting the distal port and the proximal port,

an obturator extending through at least a portion of the elongate member, the obturator having a distal portion adapted to selectively prevent movement of a sealing member in a proximal direction when the elongate member is withdrawn proximally to release the sealing member to seal the puncture of the wall of the body lumen, and

a guidewire extending through the distal opening of the elongate member, the guidewire having a transversely disposed portion at a distal region.

8. The device of claim 7, wherein the sealing member is located distally of the distal portion of the obturator.

9. The device of claim 7, further comprising

a guidewire tube extending through a lumen in the elongate member, wherein the guidewire is retained within the guidewire tube.

10. The device of claim 9, wherein the guidewire tube is stationary relative to the elongate member

11. The device of claim 7, further comprising

an actuator coupled to the elongate member, the actuator adapted to facilitate movement of the elongate member relative to the obturator.

12. The device of claim 7, wherein the elongated member prevents fluids from entering the distal opening.

13. The device of claim 7, wherein the distal port is a hole in a side wall of the elongated member tubular structure.

14. A device for sealing a puncture in a wall of a body lumen comprising:

an elongate member having a distal opening, a distal port, a proximal port, and a passage connecting the distal port and the proximal port,

an obturator extending through at least a portion of the elongate member, the obturator having a distal portion adapted to selectively prevent movement of a sealing member in a proximal direction when the elongate member is withdrawn proximally to release the sealing member to seal the puncture of the wall of the body lumen, and

a guidewire extending through the distal opening of the elongate member, the guidewire having a loop at a distal region that defines a plane that is transversely disposed relative to a proximal region of the guidewire.

15. The device of claim 14, wherein the sealing member is located distally of the distal portion of the obturator.

16. The device of claim 14, further comprising

a guidewire tube extending through a lumen in the elongate member, wherein the guidewire is retained within the guidewire tube.

17. The device of claim 14, further comprising

an actuator coupled to the elongate member, the actuator adapted to facilitate movement of the elongate member relative to the obturator.

18. The device of claim 14, wherein the sealing member prevents fluids from entering the distal opening.

19. The device of claim 14, wherein the distal port is a hole in a side wall of the elongated member tubular structure.

20. The device of claim 14, wherein the loop at the distal region of the guidewire is substantially circular in shape.
