Abstract

A tissue puncture assembly includes an ultrasound probe, a tissue puncture device, and an adjustment device. The ultrasound probe includes a probe end arranged to contact a tissue surface, the ultrasound probe being operable to determine a depth of a body cavity positioned below the tissue surface. The tissue puncture device is configured to penetrate the tissue surface to gain access to the body cavity. The adjustment device is mounted to the ultrasound probe and operable to adjust an orientation of the tissue puncture device relative to the ultrasound probe.

Claims

1. A tissue puncture assembly, comprising:

an ultrasound probe having a probe end arranged to contact a tissue surface, the ultrasound probe being operable to determine a depth of a body cavity positioned below the tissue surface;

a tissue puncture device configured to penetrate the tissue surface to gain access to the body cavity;

an adjustment device mounted to the ultrasound probe and operable to adjust an orientation of the tissue puncture device relative to the ultrasound probe.

2. The tissue puncture assembly of claim 1, wherein the adjustment device has an adjustable length to vary a distance between the ultrasound probe and the tissue puncture device.

3. The tissue puncture assembly of claim 1, wherein the adjustment device includes a pivot adjustment portion operable to change an angle or orientation of the tissue puncture device relative to the ultrasound probe.

4. The tissue puncture assembly of claim 1, further comprising a display configured to show a position of the ultrasound probe relative to the body cavity.

5. The tissue puncture assembly of claim 1, wherein the tissue surface is an outer skin surface of a patient, and the body cavity is a vessel lumen.

6. The tissue puncture assembly of claim 1, wherein the tissue puncture device comprises a hub and a puncture member mounted to the hub, the hub being adjustably mounted to the adjustment device.

7. The tissue puncture assembly of claim 1, further comprising a stabilizing member extending radially outward from the ultrasound probe and being arranged to contact the tissue surface.

8. The tissue puncture assembly of claim 7, wherein the stabilizing member comprises a circular shaped ring portion arranged to contact the tissue surface.

9. The tissue puncture assembly of claim 7, wherein the stabilizing member is adjustable along a length of the ultrasound probe.

10. The tissue puncture assembly of claim 1, wherein ultrasound probe, tissue puncture device, and adjustment device are arranged in a common plane.

11. A needle placement assembly, comprising:

an ultrasound probe;

a needle;

a needle adjustment device having a probe attachment member connected to the ultrasound probe, and a needle carrier connected to the needle and being adjustably mounted to the probe attachment member to adjust a position of the needle relative to the ultrasound probe.

12. The needle placement assembly of claim 11, wherein the needle is movable relative to the needle carrier and is insertable through a tissue layer against which the ultrasound probe abuts.

13. The needle placement assembly of claim 11, wherein the ultrasound probe is configured to abut against a tissue layer and locate a vessel positioned below the tissue layer, the needle being insertable through the tissue layer and vessel to access a lumen of the vessel.

14. The needle placement assembly of claim 13, further comprising a display showing images of the vessel generated by the ultrasound probe.

15. The needle placement assembly of claim 11, wherein the needle adjustment device includes a length adjustment portion and a pivot adjustment portion.

16. A method of accessing a vessel percutaneously, comprising:

providing a needle placement assembly having an ultrasound probe, a needle adjustment device, and a needle, the ultrasound probe and needle being mounted to the needle adjustment device;

contacting the ultrasound probe against a tissue layer;

determining a location of the vessel below the tissue layer;

adjusting the needle adjustment device to alter an orientation of the needle relative to the ultrasound probe;

advancing the needle through the tissue layer and into the vessel.

17. The method of claim 16, wherein determining a location of the vessel includes displaying images of the vessel and tissue layer on a display screen.

18. The method of claim 16, wherein adjusting the needle adjustment device includes adjusting at least one of a length and a rotated position of the needle adjustment device.

19. The method of claim 16, wherein the needle adjustment device includes a probe attachment member connected to the ultrasound probe, a needle carrier connected to the needle, and an adjustment member, and adjusting the needle adjustment device includes adjusting at least one of a distance and a rotated position of the probe attachment member relative to the needle carrier with the adjustment member.

20. The method of claim 16, further comprising providing a stabilization ring, mounting the stabilization ring to one of the ultrasound probe and the needle adjustment device, and contacting the stabilization ring against the tissue layer after determining a location of the vessel.
