Abstract

A suture applying device comprises a shaft having a nose piece attached at its distal end. The shaft and the nose piece are separated by a transition region, and a needle entry lumen in the shaft permits a flexible needle to be introduced in the distal direction. The needle is able to cross the transition region and penetrate tissue held therein and enter into a return lumen in the nose piece. The return lumen is U-shaped and acts to bend the flexible needle as it is advanced. In this way, the needle passes from the nose piece through the transition region in a proximal direction, and is able to pass through tissue within the transition region generally on the opposite side of a tissue puncture from the first suture passage. The needle then exits from the device, permitting the suture attached to the needle to be drawn fully through the device. The suture may then be tied in order to close and seal the tissue penetration.

Claims

1. A method for suturing a puncture site in the wall of a body lumen, said method comprising:

providing at least one elongate flexible needle having a distal tip and an attached length of suture;

pushing the needle so that the distal tip penetrates inwardly through an anterior surface of the wall adjacent to the puncture site and enters into the body lumen, whereby an inward penetration is formed;

elastically bending the needle as it travels within the body lumen so that the distal tip penetrates outwardly through a posterior surface of the wall adjacent to the puncture site, whereby an outer penetration is formed;

advancing the distal tip of the needle outwardly to draw suture across the puncture site; and

securing the suture to close the puncture site.

2. A method as in claim 1, wherein the needle is pushed by engaging a drive wheel against the needle and rotating the drive wheel.

3. A method as in claim 1, wherein the needle is elastically bent by travelling through a U-shaped guide path.

4. A method as in claim 1, wherein the needle is pulled from the outward penetration.

5. A method for suturing a puncture site distal to a tissue tract, said method comprising:

providing an elongate flexible needle having a distal tip and an attached length of suture;

providing a needle-guiding device which defines a needle path having an entry segment, a return segment, and an exit segment, wherein the entry and exit segments are separated from the return segment by a gap;

introducing the needle-guiding device through the tissue tract so that the gap lies within the puncture site;

pushing the needle through the entry segment of the needle path so that the needle passes through tissue adjacent the puncture, into the return segment, through tissue on the other side of the puncture site, and then into the exit segment;

advancing the distal tip of the needle outwardly from the exit segment of the needle path to draw suture from the needle-guiding device; and

securing the suture to close the puncture site.

6. A method as in claim 5, wherein the needle is composed of a superelastic alloy.

7. A method as in claim 5, wherein the needle-guiding device has a tapered, soft distal end to facilitate introduction through the tissue tract and into puncture site.

8. A method as in claim 7, wherein the tapered distal end has a generally oval cross-section adjacent the gap with the return segment being a U-shaped lumen disposed in a plane parallel to the major axis of the oval.

9. A method as in claim 8, wherein the needle-guiding device includes a transition region in the gap between the entry and exit segments and the return segment, wherein the transition region has a generally oval cross-section with a major axis oriented orthogonally relative to the major axis of the oval portion of the tapered distal end, whereby the puncture site will be conformed to expose tissue adjacent the puncture site within the gap between the entry and exit segments and the return segment.

10. A method as in claim 9, wherein the maximum peripheral length around the oval cross-section of the tapered distal end is generally equal to the maximum peripheral length around the cross-section of the transition region.

11. A method as in claim 10, further comprising withdrawing an introducer sheath from the tissue tract prior to introducing the needle-guiding device, wherein the maximum peripheral length is substantially equal to the circumference of the introducer sheath.

12. A method as in claim 5, wherein the needle-guiding device includes a shank, a transition region, and a nose piece which is rotatable about a longitudinal axis relative to the shank and transition region wherein the entry and exit segments are disposed in the shank and the return segment is disposed in the nose piece, and wherein the nose piece and transition region is a continuous oval surface when the nose piece and transition region are rotationally aligned, further comprising rotating the nose piece out of alignment with the transition region after the needle-guiding device has been introduced in order to align the entry and exit lumens with the return lumen in the nose piece.

13. A method as in claim 5, further comprising extending needle guide tubes across the gap between the entry and exit segments and the return segment after the needle-guiding device has been introduced through the tissue tract.

14. A method as in claim 5, wherein the needle is pushed by engaging a drive wheel against the needle and rotating the drive wheel.

15. A method as in claim 5, wherein the needle is pulled outwardly from the tissue tract.

16. A method as in claim 5, wherein the needle-guiding device is introduced over a guide wire which is in place in the tissue tract.

17. A method as in claim 5, wherein the needle-guiding device has an elongated nose piece and the nose piece remains within the puncture site to occlude blood flow after the suture is withdrawn from the suture path until the suture is tied to close the puncture site.

18. A suturing kit comprising:

a suturing needle including an elongate needle shank having a distal tip, said shank being composed of a flexible metal alloy; and

a length of suture attached to the needle shank; and

a needle-guiding device including a shaft having a proximal end, a distal end, an entry lumen, and an exit lumen; and

a nose piece attached to the distal end of the shaft and having a return lumen disposed to receive the suturing needle from the entry lumen and to turn the needle to enter the exit lumen, wherein the nose piece is axially spaced-apart from the distal end of the shaft to form an annular gap between the shaft and proximal end of the nose piece, wherein the gap receives tissue to be sutured.

19. A suturing kit as in claim 18, wherein the shank of the suturing needle has a length which is sufficient to extend through the entry lumen, return lumen, and exit lumen so that the shank may be pushed from the entry lumen until the distal tip emerges from the exit lumen.

20. A suturing kit as in claim 19, wherein the shank of the suturing needle has a length from 10 cm to 30 cm.

21. A suturing kit as in claim 20, wherein the gap between the shaft and the nose piece is defined by a transition region having a generally oval cross-section.

22. A suturing kit as in claim 21, where the nose piece is tapered with an oval cross-section at its proximal end, wherein the maximum peripheral length around the nose piece is generally equal to that around the transition region.

23. A suturing kit as in claim 22, wherein the nose piece comprises a tapered distal tip, a shank portion having a cylindrical cross-section with a circumference generally equal to the maximum peripheral length, and a proximal end piece which changes to an oval cross-section having a constant peripheral length generally equal to the maximum peripheral length.

24. A suturing kit as in claim 23, wherein the nose piece is fixed relative to the shaft.

25. A suturing kit as in claim 22, further comprising means for rotating the nose piece relative to the shaft and transition region.
