Abstract

A system for visualizing needle entry into a body is presented. The system includes a needle for entering a body. The needle is coated with a radiation scattering coating on at least a portion of the needle. The system additionally includes a radiation visualization device which detects reflected radiation directed at a target body and enables medical personnel to view anatomical structures such as a blood vessel along with the inserted needle within a body.

Claims

1. A system for visualizing needle entry into a body, comprising:

a needle;

a radiation scattering coating coated on the needle, the radiation scattering coating having a saturating feature comprising a pore; and

a radiation visualization device.

2. The device of claim 1, wherein the coating includes at least one polymer.

3. The device of claim 1, wherein the coating includes at least one of fluorinated ethylene propylene (FEP), polytetrafluoroethylene (PTFE), and combinations thereof.

4. The device of claim 1, wherein the coating includes at least one of a pigment and a dye that scatters incident near infrared radiation.

5. The device of claim 1, wherein the coating is coated only on the needle tip of the needle.

6. The device of claim 1, wherein the coating is coated on the needle except the needle tip.

7. The device of claim 1, wherein the coating is coated on the needle using a pattern of coated and uncoated portions.

8. The device of claim 1, wherein the radiation visualization device includes a detector that visualizes based on at least one of tomography, spectroscopy, and spectral imaging.

9. A system for visualizing needle entry into a body, comprising:

a needle; and

a radiation scattering coating coated on the needle, the coating further including a radiation scattering pigment or a radiation scattering dye having a saturating feature comprising a pore.

10. A device of claim 9, wherein the coating includes at least one of fluorinated ethylene propylene (FEP), polytetrafluoroethylene (PTFE), and combinations thereof.

11. A device of claim 10, wherein the coating is coated on the needle using a pattern of coated and uncoated portions.

12. A method visualizing needle entry into a blood vessel, comprising:

providing a needle having a radiation scattering coating comprising a saturating feature that is a pore;

providing a radiation visualization device;

inserting the needle into a blood vessel;

blocking the radiation scattering coating by saturating the pore of the saturating feature with blood; and

visualizing advancement of the needle into a blood vessel by monitoring the saturation of the pore of the saturating feature with the radiation visualization device.

13. The method of claim 12, further comprising a step for stopping advancement of the needle into the blood vessel when the needle tip of the needle is visualized as within the blood vessel.

14. The method of claim 12, further comprising a step for coating a tip portion of the needle with the radiation scattering coating.
