Anatomic needle system

1. A needle system comprising:

a housing having proximal and distal ends, and an axis extending between the proximal and distal ends;

a tubular needle secured to the housing and having a length extending outward from the distal end of the housing between proximal and distal ends of the tubular needle, the tubular needle including a straight section, and a bent section, the bent section extending distally and non-linearly from the straight section, wherein a length of the bent section substantially corresponds to a depth of a biological structure beneath a tissue surface, wherein the biological structure is at least one of a vessel, vein, artery, joint, and organ;

a base coupled to the housing such that the base is movable between a first position, in which the base extends distally from the housing and along the length of the tubular needle to cover the distal end of the tubular needle, and a second position, in which the base extends laterally away from the axis of the housing to uncover the distal end of the tubular needle.

2. The needle system of claim 1 , wherein, in the second position, the base at least partially covers the tubular needle.

3. The needle system of claim 1 , wherein the tubular needle is configured to at least one of introduce fluids to and withdraw fluids from the biological structure.

4. The needle system of claim 1 , wherein the straight section extends distally from the housing.

5. The needle system of claim 4 , wherein the base has a base surface shaped to extend along the tissue surface when the base is in the second position.

6. The needle system of claim 5 , wherein the base surface includes at least one of a substantially concave portion and a groove running along the length of the base and adapted to seat upon at least one of a convex feature and a protruding feature on the skin.

7. The needle system of claim 4 , wherein at least a portion of the tubular needle is radially expandable from a first diameter to a second diameter, wherein the second diameter is greater than the first diameter.

8. The needle system of claim 4 , wherein the tubular needle is adapted to receive an endovascular surgical device therethrough.

9. The needle system of claim 4 , wherein the bent section is angled with respect to the straight section at about 5-45 degrees.

10. The needle system of claim 9 , wherein the bent section is angled with respect to the straight section at about 35-45 degrees.

11. The needle system of claim 9 , wherein the bent section is angled with respect to the straight section at about 15-30 degrees.

12. The needle system of claim 9 , wherein the bent section is angled with respect to the straight section at about 5-15 degrees.

13. The needle system of claim 4 , wherein the length of the bent section is about 1-8 mm.

14. The needle system of claim 13 , wherein the length of the bent section is about 1-3 mm.

15. The needle system of claim 13 , wherein the length of the bent section is about 5-8 mm.

16. A penetrating device system comprising:

a housing;

a needle device including a first section, a second section, a third section, a first bend interposing the first section and the second section, a second bend interposing the second section and the third section, and a depth indicator, wherein the first, second, and third sections are non-coplanar;

a base coupled to the housing such that the base is movable between a first position and a second position, wherein the base has a base surface facing the needle device when the base is in the second position; and

a latch configured to couple the base to the housing when the base is in the second position.

17. The penetrating device system of claim 16 , wherein at least one of the first section, the second section, and the third section is non-coplanar with the others of the first section, the second section, and the third section.

18. The penetrating device system of claim 16 , wherein the penetrating device is substantially S-shaped.

19. The penetrating device system of claim 16 , wherein at least one of the first section, the second section, and the third section includes an expandable conduit.

20. The penetrating device system of claim 19 , wherein the expandable conduit is configured around at least a portion of the penetrating device.

21. The penetrating device system of claim 19 , wherein the expandable conduit is configured in a side-by-side arrangement with respect to at least a portion of the penetrating device.

22. The penetrating device system of claim 16 , wherein the needle device includes at least one of a substantially solid needle and a substantially hollow needle.

23. A needle system comprising:

a housing having proximal and distal ends, and an axis extending between the proximal and distal ends;

a tubular needle having proximal and distal ends and including a straight section extending distally from the housing, a bent section extending distally and non-linearly from the straight section, wherein a length of the bent section substantially corresponds to a depth of a biological structure beneath a tissue surface, wherein the biological structure is at least one of a vessel, vein, artery, joint, and organ;

a base coupled to the housing such that the base is movable between a first position, in which the base extends distally from the housing and along the length of the tubular needle to cover the distal end of the tubular needle, and a second position, in which the base extends laterally away from the axis of the housing to uncover the distal end of the tubular needle; and

a latch configured to lock the base in the second position.
