Abstract

A needle-hub assembly, the improvement comprising a small tissue deflector connected to the needle, wherein the deflector deflects tissues away from the hub to prevent needle penetration to the hub, but permits the needle to bend adjacent to the hub, thereby enhancing the retrievability of the needle from the tissues if the needle were to separate.

Claims

1. A needle-hub assembly comprising a needle connected to a hub, the improvement comprising a tissue deflector connected to said needle, wherein said deflector is shaped to inhibit insertion of said deflector into the tissues, thereby enhancing the retrievability of a separated said needle from the tissues.

2. The needle-hub assembly of claim 1, wherein said deflector is connected directly to said hub.

3. The needle-hub assembly of claim 1, wherein said deflector is not connected to said hub.

5. The needle-hub assembly of claim 1, wherein said deflector is substantially comprised of a sleeve.

6. The needle-hub assembly of claim 1, wherein said deflector indicates the location of the bevel of said needle.

4. The needle-hub assembly of claim 4, wherein said deflector is substantially comprised of a small mass adhered to said needle.

7. A needle-hub assembly comprising a needle connected to a hub, the improvement comprising a tissue deflector connected to said needle, said deflector having an end distal from said hub called a stop, and said needle having a portion interposed between said stop and said hub called a proximal needle, wherein said deflector permits user to bend said proximal needle, and wherein said deflector is shaped to inhibit insertion of said deflector into the tissues, thereby enhancing the retrievability of a separated said needle from the tissues.

8. The needle-hub assembly of claim 7, wherein said deflector is connected directly to said hub.

9. The needle-hub assembly of claim 7, wherein said deflector is not connected to said hub.

10. The needle-hub assembly of claim 9, wherein said deflector is comprised of a small mass adhered to said needle.

11. The needle-hub assembly of claim 7, wherein said deflector is substantially comprised of a sleeve.

12. The needle-hub assembly of claim 7, wherein said deflector permits bending of said needle between said deflector and said hub.

13. The needle-hub assembly of claim 7, wherein said deflector indicates the location of the bevel of said needle.

14. A needle-hub assembly comprising a needle connected to a hub, the improvement comprising a tissue deflector connected to a location along the length of said needle, wherein said deflector is shaped to inhibit insertion of said deflector into the tissues, such that said deflector permits said needle to penetrate to only to the location of said deflector, and inhibits needle penetration beyond the location of said deflector, thereby enhancing the retrievability of a separated said needle from the tissues.

15. The needle-hub assembly of claim 14, wherein said deflector is connected directly to said hub.

16. The needle-hub assembly of claim 14, wherein said deflector is not connected to said hub.

17. The needle-hub assembly of claim 16, wherein said deflector is comprised of a small mass adhered to said needle.

18. The needle-hub assembly of claim 14, wherein said deflector is substantially comprised of a sleeve.

19. The needle-hub assembly of claim 14, wherein said deflector permits bending of said needle between said deflector and said hub.

20. The needle-hub assembly of claim 14, wherein said deflector indicates the location of the bevel of said needle.
