Abstract

Device and method for puncturing blood vessels while using fluoroscopy. The disclosed device enables improved needle orientation control and avoids direct exposure of the clinician'"'"'s hand to X-ray during the puncturing procedure.

Claims

1. A method comprising:

(i) connecting a needle to a needle holder, the needle holder comprising;

an elongate stiff member having a proximal end, a distal end, and a longitudinal axis;

a connector coupled to the distal end of the elongate stiff member;

a guidewire holder coupled to the elongate stiff member proximally of the distal end, the guidewire holder comprising;

(a) a flexible locking element located proximally of the distal end of the elongate stiff member;

(b) a sliding knob arranged to slide over the locking element in a direction parallel to the longitudinal axis and force the flexible locking element in a radial direction;

a lumen traversing the connector, the elongate stiff member, and the guidewire holder, wherein the lumen comprises an inner wall and an opening, wherein the opening is disposed proximally of the locking element;

(ii) inserting a guidewire into the lumen;

(iii) after (ii), sliding the sliding knob thereby causing the flexible locking element to directly contact and hold the guidewire in position relative to the connector;

(iv) after (iii), inserting the needle into a blood vessel;

(v) after (iv), sliding the sliding knob thereby releasing the flexible locking element from holding the guidewire in the position relative to the connector; and

(vi) after (v), inserting the guidewire into the blood vessel through the lumen and the needle.

2. The method according to claim 1, wherein inserting the needle into the blood vessel comprises using x-ray angiography.

3. The method according to claim 1, further comprising confirming that the needle is positioned in the blood vessel by viewing blood in the elongate stiff member.

4. The method according to claim 1, further comprising, after (vi), removing the needle holder together with the needle from the blood vessel.

5. The method according to claim 4, further comprising removing the needle holder and the needle proximally from the guidewire.

6. The method according to claim 5, further comprising conducting an angioplasty procedure after removing the needle holder and the needle proximally from the guidewire.

7. The method according to claim 1, wherein (iii) sliding the sliding knob comprises sliding the sliding knob in a first direction, and wherein (v) sliding the sliding knob comprises sliding the sliding knob in a second direction.

8. The method according to claim 1, wherein inserting the needle into the blood vessel comprises inserting the needle with a retrograde approach.

9. The method according to claim 1, wherein the blood vessel is an artery.

10. The method according to claim 9, wherein inserting the needle into the artery comprises inserting the needle with a retrograde approach.

11. The method according to claim 10, further comprising, after (vi), removing the needle holder together with the needle from the artery.

12. The method according to claim 11, further comprising conducting an angioplasty procedure after removing the needle holder together with the needle from the artery.

13. The method according to claim 1, wherein the connector comprises a male luer connector.

14. The method according to claim 1, wherein the opening comprises a female luer connector.

15. The method according to claim 1, wherein the needle holder has a length of at least 12 cm.

16. The method according to claim 1, wherein the needle holder has a length of 20 cm to 25 cm.

17. The method according to claim 1, further comprising a second opening in fluid communication with the lumen.

18. The method according to claim 17, wherein the second opening is located distal to the flexible locking element and proximal of the distal end of the elongate stiff member.

19. The method according to claim 1, wherein the elongate stiff member is constructed of a clear polymeric material.

20. The method according to claim 1, wherein the flexible locking element is located within a hole within the elongate stiff member.
