Abstract

A surgical device of suturing vascular vessels is described, as well as methods for suturing tissue employing the surgical device. The device includes at least one needle advanceable through tissue and into a needle capture element within a distal end of the surgical device to draw lengths of suture material which can then be used to close various puncture wounds, particularly in vascular tissue.

Claims

1. A method of suturing vascular tissue adjacent an opening in a vascular vessel, said method comprising:

inserting a suturing device through the opening in the vascular vessel, said suturing device comprising;

a proximal member having a needle channel and a first needle and a second needle therein, said first needle and said second needle carrying a length of suture material;

a distal member configured to be inserted into the lumen of the vascular vessel, the distal member having a receptacle comprising a needle capture element and being sized to receive said first needle and said second needle therein, the needle capture member including an interior wall portion and a first plurality of projections and a second plurality of projections, the first and second pluralities of projections extending at an angle away from the interior wall portion toward a distal end of the distal member, the first plurality of projections being longitudinally offset from the second plurality of projections; and

an intermediate member disposed between the proximal member and the distal member, the intermediate member defining a tissue receiving area and configured to provide a linear needle pathway between the channel and the receptacle;

advancing said first needle distally along the needle channel to pierce the vascular tissue and draw a portion of the length of suture material through the vascular tissue; and

engaging said first needle with the needle capture element in the receptacle by inserting said first needle between the first and/or second plurality of projections.

2. The method of claim 1 comprising sequentially advancing at least said first needle and said second needle along the needle channel and into the receptacle.

3. The method of claim 1 comprising withdrawing the suturing device from the opening in the vascular vessel with said first needle retained within the receptacle.

4. The method of claim 3 comprising pulling suture material distally through vascular tissue adjacent the opening.

5. The method of claim 4 comprising pulling suture material proximally out the opening.

6. The method of claim 5 comprising pulling two lengths of suture material proximally out the opening.

7. The method of claim 6 comprising securing the two lengths of suture material together.

8. The method of claim 7 wherein said securing comprises tying the two lengths of suture material together.

9. The method of claim 7 wherein said securing comprises using a suture securing device to secure the two lengths of suture material together.

10. The method of claim 7 comprising using a knot pusher to secure the two lengths of suture material together.

11. The method of claim 1 further comprising rotating said suturing device from a first position to a second position.

12. The method of claim 1 further comprising:

advancing said second needle distally along the needle channel to pierce the vascular tissue and draw a portion of the length of suture material through the vascular tissue; and

engaging said second needle with the needle capture element in the receptacle.

13. The method of claim 1 wherein said first needle and said second needle share a common length of suture.

14. The method of claim 1 wherein said suturing device further comprises a guide wire lumen.

15. The method of claim 1 wherein said suturing device further comprises a locator.

16. The method of claim 15 wherein said locator further comprises a bleed back lumen.

17. The method of claim 1, wherein the first plurality of projections are all positioned at the different longitudinal location and distributed about the longitudinal axis.

18. The method of claim 1, wherein the first needle and the second needle both have a body that is substantially straight and wherein the first needle and the second needle each further comprise a distal tip that tapers inward from the substantially straight body.

19. The method of claim 1, wherein the first plurality of projections and the second plurality of projections cooperate to resist the proximal movement of both the first needle and the second needle.

20. A method of suturing vascular tissue adjacent an opening in a vascular vessel, said method comprising:

inserting a suturing device through the opening in the vascular vessel, said suturing device comprising;

a proximal member having a needle channel and a first needle and a second needle therein, said first needle and said second needle carrying a length of suture material, said first needle and said second needle both having a body that is substantially straight, said first needle and said second needle each further comprising a distal tip that tapers inward from the substantially straight body;

a distal member configured to be inserted into the lumen of the vascular vessel, the distal member having a receptacle comprising a needle capture element and being sized to receive said first needle and said second needle therein, the needle capture member including an interior wall portion and a first plurality of projections and a second plurality of projections, the first and second pluralities of projections extending at an angle away from the interior wall portion toward a distal end of the distal member, the first plurality of projections being longitudinally offset from the second plurality of projections; and

an intermediate member disposed between the proximal member and the distal member, the intermediate member defining a tissue receiving area and configured to provide a linear needle pathway between the channel and the receptacle;

advancing said first needle distally along the needle channel to pierce the vascular tissue and draw a portion of the length of suture material through the vascular tissue;

engaging said first needle with the needle capture element in the receptacle;

following advancing said first needle distally along the needle channel and engaging said first needle with the needle capture element, rotating said suturing device from a first position to a second position;

following rotating said suturing device from a first position to a second position, advancing said second needle distally along the needle channel to pierce the vascular tissue and draw a portion of the length of suture material through the vascular tissue and engaging said second needle with the needle capture element in the receptacle.

21. The method of claim 20, wherein the first plurality of projections are all positioned at the different longitudinal location and distributed about the longitudinal axis.

22. The method of claim 20, wherein the first needle and the second needle both have a body that is substantially straight and wherein the first needle and the second needle each further comprise a distal tip that tapers inward from the substantially straight body.

23. The method of claim 20, wherein the first plurality of projections and the second plurality of projections cooperate to resist the proximal movement of both the first needle and the second needle.
