Abstract

An apparatus for accessing the lumen of a vessel. The apparatus includes a handheld device and a cartridge. The handheld device includes an imaging device attachment utilized to secure an image capturing instrument, an arm coupled to the imaging device attachment. The cartridge includes a sheath, needle or guidewire coupled to the cartridge. The sheath or needle extends to the insertion depth when fully advanced, thereby allowing the sheath, needle, or guidewire to access the lumen of a vessel.

Claims

1. A handheld apparatus for accessing a lumen of a vessel, the handheld apparatus comprising:

an arm providing a cartridge;

a body providing an image device attachment, wherein said arm is pivotally attached to said body, the image device attachment is positioned adjacent to a pivot point of said arm, and a center of gravity of said handheld apparatus is positioned adjacent to said pivot point where said arm is coupled to said body;

a slider coupled to the cartridge, wherein said slider secures a needle;

a slide stop secured to said body; and

a stop extension extending from said slider, wherein said stop extension contacts said slide stop when said slider is advanced a predetermined length, and said stop extension and slide stop prevent the slider from advancing beyond said predetermined length;

wherein the center of gravity of said handheld apparatus is positioned at a point below a midpoint of a height of the handheld apparatus.

2. The handheld apparatus of claim 1, further comprising a depth scale secured to said body, wherein said depth scale provides a scale indicating an insertion depth.

3. The handheld apparatus of claim 2, further comprises:

a thumb wheel coupled to the arm, wherein rotation of the thumb wheel adjust said arm along said depth scale; and

an indicator provided by said arm, wherein the indicator specifies said insertion depth on the depth scale.

4. The handheld apparatus of claim 2, wherein said handheld apparatus does not utilize electric power.

5. The handheld apparatus of claim 1, wherein said body provides an arc-like structure, said image capturing instrument is positioned at a center of a width of the handheld apparatus, and a pivot point of said arm is positioned adjacent to an image capturing instrument.

6. The handheld apparatus of claim 5, wherein the center of gravity of said handheld apparatus is positioned at a point adjacent to an axis centered at midpoint of a width of the handheld apparatus.

7. The handheld apparatus of claim 6, wherein the center of gravity of the handheld apparatus is positioned near where the handheld apparatus is held by an operator.

8. The handheld apparatus of claim 1, wherein the image device attachment secures an image capturing instrument, and said image capturing instrument is a preexisting image capturing instrument.

9. The handheld apparatus of claim 1, wherein said cartridge is removable from said arm.

10. The handheld apparatus of claim 1, wherein said cartridge is not removable from said arm.

11. The handheld apparatus of claim 1, wherein pivoting of said arm and advancing said slider is motorized.

12. The handheld apparatus of claim 11, wherein said handheld apparatus is operable with a single hand.

13. The handheld apparatus of claim 1, wherein the said imaging device attachment is an ergonomic handle.

14. The handheld apparatus of claim 13, wherein an image capturing instrument is incorporated into said ergonomic handle.

15. The handheld apparatus of claim 14, wherein one or more controls are positioned on said ergonomic handle, and said handheld apparatus is operable with a single hand.

16. A handheld apparatus for accessing a lumen of a vessel, the handheld apparatus comprising:

an arm providing a cartridge;

a body providing an image device attachment, wherein said arm is pivotally attached to said body, the image device attachment is positioned adjacent to a pivot point of said arm;

a slider coupled to the cartridge, wherein said slider secures a needle; and

wherein a center of gravity of the handheld apparatus is positioned adjacent to said pivot point, said center of gravity is positioned adjacent to an axis centered on a midpoint of a width of the handheld apparatus, and said center of gravity is positioned below a midpoint of a height of the handheld apparatus.

17. The handheld apparatus of claim 16, further comprising:

a slide stop secured to said body; and

a stop extension extending from said slider, wherein said stop extension contacts said slide stop when said slider is advanced a predetermined length, and said stop extension and slide stop prevent the slider from advancing beyond said predetermined length.

18. The handheld apparatus of claim 16, further comprising a depth scale secured to said body, wherein said depth scale provides a scale indicating an insertion depth.

19. The handheld apparatus of claim 16, wherein said handheld apparatus does not utilize electric power.

20. The handheld apparatus of claim 16, wherein the image device attachment secures an image capturing instrument, said image capturing instrument is a preexisting image capturing instrument, and said image capturing instrument is positioned at a center of a width of the handheld apparatus.

21. The handheld apparatus of claim 20, wherein the center of gravity of the handheld apparatus is positioned near where the handheld apparatus is held by an operator.

22. The handheld apparatus of claim 16, wherein pivoting of said arm and advancing said slider is motorized, and said apparatus is operable with a single hand.
